Best AI Pine Script Generator: 7 Tools Compared (2026)

Best AI Pine Script Generator: 7 Tools Compared (2026)

By HorizonAI Team

There's no single best AI for Pine Script. There are four that win different jobs. If you live entirely inside TradingView and prefer to pay once, Pineify. If you want to try an AI Pine tool for free today, PineGen AI's free tier or Claude. If you already subscribe to LuxAlgo, Quant is bundled with what you're paying for. If the same strategy also has to run on MetaTrader 5 or NinjaTrader, HorizonAI.

The fuller answer: every tool on this list can turn "buy when RSI crosses back above 30 in an uptrend" into something that compiles. They separate on four things that matter far more than raw generation quality. Does it validate against a real compiler or just hope? Can you see the script on a chart before you paste it into TradingView? Can you test it, and whose engine produces the numbers? And does it only speak Pine Script, or can it move your logic to another platform when you outgrow TradingView? Those four questions decide which tool is right for you, and they're the structure of everything below.

One thing to know up front about this category: most of the "best AI Pine Script generator" roundups on the web are published by one of the vendors, which ranks itself first. The most-cited example, Pineify's own list, puts Pineify at number one and doesn't mention several real competitors at all (pineify.app, fetched July 2026). We publish HorizonAI, so treat this page the same way, and check the linked sources yourself. Every price and feature below was fetched from the vendor's own site in July 2026.

What actually makes an AI good at Pine Script

Pine Script punishes general-purpose language models in a specific way. It's a series-based language: close isn't a number, it's a whole vector of values indexed by bar, and almost every function you call is executed once per bar with its own internal state. A model that has read a lot of Python and JavaScript will confidently write Pine that looks right and behaves wrong.

Four failure modes show up over and over, and they're the things a Pine-specific tool is supposed to fix:

  1. Version drift. Pine Script v6 broke real things. Booleans can no longer hold na at all, expressions that returned a boolean na in v5 now return false, int and float values are no longer implicitly cast to bool, integer division now keeps its fractional part, and the when parameter was removed from the strategy functions (v6 migration guide). A model trained on years of v4 and v5 forum posts will write strategy.entry("Long", strategy.long, when = cond) and label the file //@version=6 anyway.
  2. Repainting by default. Higher-timeframe requests with lookahead=barmerge.lookahead_on and no offset give the script future data on historical bars. The backtest looks incredible and the live chart doesn't match.
  3. Compile errors that read like prose. "Cannot call 'ta.sma' with argument 'length'=..." tells you nothing if you can't see the series types involved.
  4. Silent logic inversion. ta.crossover(rsi, 30) and rsi < 30 are not the same signal. One fires on the single bar RSI comes back up through the level; the other is true on every bar of the entire oversold stretch. Both compile.

A tool that runs your generated script through a genuine compile step catches numbers 1 and 3 mechanically. Numbers 2 and 4 need either a chart preview or a backtest, which is why "does it have a chart" turns out to be a better buying criterion than "which model does it use."

Pineify

What it is: the most feature-dense product in the category. Pineify sells a Pine Script coding agent, an MQL5 coding agent, a no-code visual Pine editor with 235+ built-in indicators, and then a large surround of non-coding tools: a custom screener, a trading journal, a strategy optimizer browser extension, a backtest report, an AI stock and options picker, and market-insight feeds like options flow and dark pool data (pineify.app, fetched July 2026).

Pricing at time of writing: one-time payments, not a subscription. Plus $99, Advanced $149, Expert $259, each discounted from a higher list price, each granting a monthly AI-credit allowance forever (500, 1,000 and 2,500 credits respectively). Their pricing page carries a banner saying lifetime pricing is going away and that they're moving to annual subscriptions, so the one-time offer may not exist by the time you read this.

Where Pineify genuinely beats HorizonAI: on total cost of ownership, badly. If you're going to be generating Pine Script for the next three years, $149 once is less than half of what any monthly plan costs you over that horizon. Its visual builder is also more developed than HorizonAI's flow builder for the specific job of assembling an indicator out of pre-built blocks without describing anything in words. And nothing in HorizonAI touches screeners, journals or options-flow data, because HorizonAI isn't a market-data product at all.

The catch: the "credits" model means the lifetime purchase buys you a monthly allowance, not unlimited use, and the heaviest tier is $259. The blog post that ranks Pineify number one is Pineify's own marketing, and its headline stat, that "about 85% of the time, the code compiles perfectly on the first try," is self-reported with no published methodology. We keep a longer side-by-side at HorizonAI vs Pineify.

PineGen AI

What it is: the narrowest and, for a lot of people, the most sensible option. PineGen does one thing: plain-English prompt in, compiler-validated Pine Script v6 out, with a TradingView chart preview, a backtest summary, a prompt builder, threaded chats so you can refine a strategy over many turns, and a code-explanation mode (pinegen.ai, fetched July 2026).

Pricing at time of writing: a genuinely free Basic tier with 5 credits per month, 1 chat thread, and limited backtesting and preview. Pro is $39/month with 50 credits and 5 threads. Business gives 200 credits and 20 threads (pinegen.ai/pricing).

What PineGen does better than HorizonAI: it's free to start, with no card and no clock. HorizonAI's trial is one-time and expires after 7 days, so if you generate one script a month, PineGen's free tier is simply a better fit and it always will be. Its chart-preview-plus-backtest-summary loop is also tight and purpose-built.

The limit: Pine Script only. There's no MQL5, no NinjaScript, and no conversion path, so the moment your idea needs to run on a broker's MT5 terminal you're starting over somewhere else. The homepage claims of "200K+ users" and a "98% Success Rate" are unaudited vendor marketing; treat them the way you'd treat any number a company publishes about itself.

LuxAlgo Quant

What it is: LuxAlgo is best known for its indicator toolkits, and Quant is the AI layer bolted onto them. It generates Pine Script v6 indicators and strategies, renders them on a live chart as you describe them, and runs a validation chain that LuxAlgo describes as syntax verification, variable-scope analysis, series-type inference and runtime sanity checks across 10,000 bars of data. It claims a 96% pass rate over 100 test indicators (luxalgo.com, fetched July 2026). The Quant workspace also offers a "Generate From Image" mode, which turns a chart screenshot into code.

Worth separating from Quant: LuxAlgo's AI Backtesting Assistant is a different product that gets conflated with it in roundups. It doesn't backtest your code. It answers natural-language questions against a precomputed database of backtests of LuxAlgo's own toolkit strategies, recomputed on their internal system three times a week, on Mondays, Wednesdays and Fridays at 23:30 UTC (docs.luxalgo.com). That's a useful research tool and not at all the same thing as testing a script you wrote.

Where LuxAlgo genuinely beats HorizonAI: image-to-code has no equivalent in HorizonAI. If you screenshot a chart from a YouTube video and want the indicator behind it, Quant will attempt that and HorizonAI won't. And if you're already paying for LuxAlgo's toolkits, Quant costs you nothing extra.

The catch: we couldn't retrieve LuxAlgo's live pricing page programmatically, so we're not going to quote plan prices. Check them yourself. LuxAlgo's docs also state the AI Backtesting Assistant is Ultimate-tier while the same page's FAQ says all users get some access, which is worth clarifying with their support before you buy on that basis. Quant is Pine-only.

HorizonAI

What it is: a code generator built around the assumption that TradingView isn't the last platform you'll use. It generates Pine Script v6, MQL5 and NinjaScript from chat, validates all three against real compilers, and converts between any two of them in either direction. It backtests MQL5 strategies through the MetaTrader 5 Strategy Tester and feeds the results back into the chat so you can iterate on the code and re-run. Pine Script strategies are backtested on TradingView itself through the HorizonAI Chrome extension, which drives the TradingView Strategy Tester in your own browser and returns the report to the conversation. There's a Monaco editor, a visual flow builder, and a script library with weekly drops.

Pricing: a one-time 7-day free trial with no credit card, then Starter $12, Pro $25, Elite $39 per month.

The honest limits. There's no free-forever tier, so casual users are better served by PineGen's free plan. It's a subscription, so anyone planning years of use will pay more than a Pineify or GetPineScript lifetime licence. TradingView backtesting requires Pro or Elite, since the Chrome extension isn't available on Starter. HorizonAI has no screener, no trading journal, no options-flow data and no image-to-code. It doesn't publish scripts to TradingView for you, and it doesn't generate Python. It writes the code; you run it. It isn't a broker, it doesn't execute trades, and it holds no funds.

Where it wins: the conversion path. If you've read our comparison of MQL5 vs Pine Script, you know the two languages express the same idea very differently, and a hand translation of a mid-sized strategy is an afternoon of work. Being able to take a working Pine strategy, convert it to MQL5, backtest it in MT5's Strategy Tester, and then push a NinjaScript version to NinjaTrader is a workflow no Pine-only tool on this list offers.

GetPineScript

What it is: the honest outlier. GetPineScript states plainly on its own site that it "is not an AI oriented project": it uses AI only to decide how to combine indicators, and generates the actual code through traditional templating for accuracy (getpinescript.com, fetched July 2026). You pick from 40+ indicators, choose entry and exit conditions, add filters (MA trend, ADX, session and day-of-week, date range), and configure take-profit and stop-loss by ATR, percentage or pips.

Pricing at time of writing: $99 one-time for unlimited generation, with two free scripts to try it.

Where it beats every AI tool here: determinism. Template-generated code cannot hallucinate a function that doesn't exist. If your strategy is a standard indicator combination with ATR-based risk, GetPineScript will produce code that compiles and does what the form said it would, every time. That's a real advantage over any language model.

Where it stops: it only builds what the form allows. Anything genuinely custom, a bespoke market-structure rule, a multi-symbol condition, a session-anchored calculation, is out of reach.

Claude, ChatGPT and general assistants

General models are the most-used Pine Script tool in the world and nobody sells them as one. They're free or roughly $20/month, they have enormous context windows, and they're better than every specialised tool on this list at one specific thing: explaining why your code does what it does. Paste a 200-line script you inherited and ask what breaks on the first bar, and a good general model will walk you through it properly.

They're also the weakest on the four failure modes above. There's no compiler in the loop, so version drift goes uncaught until TradingView rejects the paste. There's no chart, so a repainting request.security call looks like a winner. And there's no backtest, so you can't tell an inverted condition from a rare one.

The practical pattern that works: use a specialised tool to generate and validate, and a general assistant to interrogate the result. That's not a compromise, it's just using each for what it's actually good at.

PineReady, and a note on roundup rot

PineReady appears in a lot of "best Pine Script generator" lists, including AI-tool directories that still carry a full feature description. As of 27 July 2026, pineready.com returns NXDOMAIN: the domain doesn't resolve at all. We couldn't reach it over HTTP either.

We're leaving it on the list rather than quietly deleting it, because it illustrates the actual state of this category. Half the roundups you'll find were written once and never rechecked, and several of the tools in them are dead, rebranded, or on completely different pricing than the article says. Before you buy anything on the strength of a comparison post, including this one, open the vendor's pricing page.

The benchmark prompt: test any of these in ten minutes

The fastest way to grade a Pine Script AI is to give every candidate the same non-trivial prompt and read the code. Use this one, because it contains three traps: a confirmation requirement, a trend filter, and a stop that must be fixed at entry rather than trailing the current bar.

Write a Pine Script v6 strategy. Go long when RSI(14) has stayed below 30 for at least 2 consecutive bars and price is above the 200 EMA. Exit when RSI crosses above 55, or on an ATR(14) stop set at 2x ATR below the entry price. Percent-of-equity sizing at 10%, 0.05% commission.

Good output looks like this:

//@version=6
strategy("RSI Mean Reversion + EMA Filter", overlay=true,
     initial_capital           = 10000,
     default_qty_type          = strategy.percent_of_equity,
     default_qty_value         = 10,
     commission_type           = strategy.commission.percent,
     commission_value          = 0.05,
     process_orders_on_close   = true)

// --- Inputs
rsiLen      = input.int(14,    "RSI Length",         minval = 2)
rsiBuy      = input.int(30,    "RSI Oversold",       minval = 1,  maxval = 50)
rsiExit     = input.int(55,    "RSI Exit Level",     minval = 50, maxval = 95)
trendLen    = input.int(200,   "Trend EMA Length",   minval = 20)
atrLen      = input.int(14,    "ATR Length",         minval = 1)
atrMult     = input.float(2.0, "ATR Stop Multiple",  minval = 0.5, step = 0.1)
confirmBars = input.int(2,     "Bars RSI must hold oversold", minval = 1, maxval = 5)

// --- Series
rsiVal  = ta.rsi(close, rsiLen)
trendMa = ta.ema(close, trendLen)
atrVal  = ta.atr(atrLen)

// RSI must SIT below the level for confirmBars bars, not just tag it once.
// nz() matters here: barssince() is na until the condition has been true.
oversoldRun = nz(ta.barssince(rsiVal >= rsiBuy), 0)

longSetup = oversoldRun >= confirmBars and close > trendMa and barstate.isconfirmed
longExit  = ta.crossover(rsiVal, rsiExit)

// --- Orders
if longSetup and strategy.position_size == 0
    // Stop is priced off the entry bar and never moves. A trailing calc here
    // would silently turn this into a different strategy.
    stopPrice = close - atrMult * atrVal
    strategy.entry("Long", strategy.long)
    strategy.exit("Long Stop", from_entry = "Long", stop = stopPrice)

if longExit and strategy.position_size > 0
    strategy.close("Long", comment = "RSI target")

// --- Visuals
plot(trendMa, "Trend EMA", color = color.new(color.orange, 0), linewidth = 2)
bgcolor(longSetup ? color.new(color.teal, 90) : na, title = "Setup bars")
plotchar(longSetup, "Setup", "▲", location.belowbar, color.teal, size = size.tiny)

Grade what comes back on five points:

  • ✅ Declares //@version=6 and uses strategy(), not study()
  • ✅ Uses a real confirmation window (ta.barssince with nz, or a counter), not a bare rsiVal < 30
  • ✅ Computes the stop once at entry and passes it to strategy.exit, rather than recalculating it from the current bar every bar
  • ✅ Guards the entry with strategy.position_size == 0 so it doesn't pyramid by accident
  • ❌ Fails if it invents parameters, calls strategy.exit without from_entry, or hard-codes 30 and 55 instead of exposing inputs

The third point is the one worth staring at. A stop recalculated from the current bar on every bar isn't a stop at 2x ATR below entry, it's a loose trailing stop, and the compiler has no opinion about it. It's the most expensive silent bug in the whole prompt, and it's the one a tool with no chart and no backtest in the loop is least likely to catch.

Where all of these tools still get it wrong

❌ The repainting higher-timeframe call. Any generator on this list can hand you this if you ask for a higher-timeframe filter and say nothing about repainting:

// ❌ Sees the future on historical bars. Backtest looks superb, live does not.
htfTrend = request.security(syminfo.tickerid, "60", ta.ema(close, 50),
     lookahead = barmerge.lookahead_on)

✅ Ask for the confirmed value instead. Offsetting the requested expression by one bar makes the script use the previous, already-closed higher-timeframe bar, which is the standard non-repainting form. The request.security signature and what lookahead actually does are both in TradingView's Pine Script v6 reference:

// ✅ Uses the previous, already-closed HTF bar. Historical and live agree.
htfTrend = request.security(syminfo.tickerid, "60", ta.ema(close, 50)[1],
     lookahead = barmerge.lookahead_on)

❌ Trusting the backtest number the tool hands you. TradingView's broker emulator fills orders using chart data only, executes on historical bars after the bar closes, and infers intrabar movement from OHLC: if the open is nearer the high than the low, it assumes open → high → low → close (TradingView strategies docs). On a 4-hour chart that assumption is doing a lot of work. Bar Magnifier narrows it using lower-timeframe data on Premium plans, but the same docs cap a script at 200,000 requested lower-timeframe bars, so long histories can lose intrabar coverage entirely.

✅ Re-run on a lower timeframe before you believe anything. More broadly, most of what goes wrong here isn't the AI's fault at all; it's testing method. Our guide to backtesting mistakes to avoid covers the rest.

❌ Assuming "AI-generated" means "tested." None of these tools knows whether your idea has an edge. They know whether it compiles.

Generating this without writing the code yourself

If you're evaluating HorizonAI against the tools above, the fair test is the same benchmark prompt, then the thing only it does. Paste this in:

Write a Pine Script v6 strategy: long when RSI(14) has stayed below 30 for at least 2 consecutive bars and close is above the 200 EMA. Exit on RSI crossing above 55 or a 2x ATR(14) stop fixed at the entry price. Percent-of-equity sizing at 10%, commission 0.05%.

Then, once the code compiles and you've looked at it on a chart:

Convert this strategy to MQL5 for MetaTrader 5, keeping the same RSI confirmation window and the fixed 2x ATR stop, and backtest it on EURUSD H1.

What comes back is compile-checked code in both languages, editable in chat or in the built-in Monaco editor, plus an MT5 Strategy Tester report for the MQL5 version that you can iterate against without leaving the conversation. On Pro and Elite, the Chrome extension will also run the Pine version through TradingView's own Strategy Tester and bring the report back. HorizonAI writes and tests the code; you're the one who decides to trade it.

FAQs

What is the best AI for Pine Script?

It depends on what else you need. Pineify is the strongest single-purchase option for someone who works only in TradingView and wants a large surround of extra tools. PineGen AI is the best free starting point. LuxAlgo Quant makes sense if you already pay for LuxAlgo. HorizonAI is the one to pick if your strategies also need to run on MetaTrader 5 or NinjaTrader, because it converts between Pine Script, MQL5 and NinjaScript in any direction.

Can ChatGPT or Claude write Pine Script?

Yes, and they're good at explaining Pine Script, but neither compiles what it writes. Both will occasionally emit version 5 syntax under a version 6 header, and neither can show you the script on a chart, so repainting and inverted-logic bugs survive until you paste the code into TradingView yourself. Use them to interrogate and debug code rather than as your only generator.

Is there a free AI Pine Script generator?

PineGen AI has a free Basic tier with 5 credits per month and one chat thread, which is the closest thing to a genuinely free purpose-built option at time of writing. GetPineScript gives you two free script generations before asking for its one-time fee. HorizonAI has no free-forever tier: new accounts get a one-time 7-day trial with no credit card, then paid plans start at $12 a month.

Do AI-generated Pine Script strategies actually work?

They compile, which is not the same claim. Every tool here validates syntax to some degree, and the better ones run the script against real bars, but none of them can tell you whether your idea has an edge. The generated code is a starting point you still have to test properly, on out-of-sample data, on more than one symbol, with realistic commission and slippage.

Can any of these tools backtest Pine Script for me?

Partly. PineGen and LuxAlgo Quant include their own in-tool testing and preview. HorizonAI takes a different route for Pine, running the script through TradingView's own Strategy Tester via its Chrome extension on Pro and Elite plans, and backtests MQL5 strategies through the MetaTrader 5 Strategy Tester. Whichever you use, confirm the result inside TradingView before you rely on it, since the fill assumptions differ between engines.

Which AI tool can convert Pine Script to MQL5?

Pineify has separate Pine Script and MQL5 agents, and HorizonAI converts directly between Pine Script, MQL5 and NinjaScript in either direction with compiler validation on the output. The rest of the tools on this list are Pine Script only. Conversion is never perfectly mechanical, because MetaTrader's tick-based execution model differs from TradingView's bar-close model, so always re-test the converted version.

Final thoughts

The category is younger than the marketing suggests. The three loudest accuracy numbers in it, 85%, 96% and 98%, are all self-reported by the vendors making them, with no shared benchmark and no published method behind any of them, and one widely listed tool's domain has stopped resolving entirely. Pick on the four criteria at the top of this page rather than on a percentage in a hero section.

One concrete tip to leave with: whatever tool you choose, make your first prompt the benchmark above and read the stop-loss line before anything else. A stop recalculated from the current bar instead of fixed at entry is the failure that survives compilation, survives the chart preview, and quietly flatters the backtest. If a tool gets that right unprompted, it will probably get the rest right too. From there, our Pine Script tutorial for beginners will get you to the point where you can read the output rather than trusting it.
