An AI that writes Pine Script and checks its own work.
Describe an indicator or strategy in plain English. PineScripter writes Pine Script v6, finds and fixes its own compile errors, and edits only the lines a follow-up changes.
Describe the indicator. The AI plans it before it writes it.
You write what you want the way you would explain it to a developer: "mark a lower low in price with a higher low in RSI and alert me when it happens." PineScripter turns that into a checklist of requirements, asks a question when something is genuinely ambiguous, and then writes Pine Script v6 against the checklist.
When it is done it checks the script against every requirement and explains what it built in plain English, so you know what the code does without reading it line by line.
- Requirements checklist with validation at the end
- Clarifying questions instead of guesses
- Attach a screenshot of a chart or an existing script file
It catches its own compile errors before you see them.
Most Pine Script errors you meet with a general chatbot are mechanical: a function that does not exist, a series passed where a simple value is required, a v5 call in a v6 script. PineScripter runs every draft through a built-in lint engine that checks it the way TradingView does.
When a check fails, the AI reads the error, fixes the line, and checks again. Each pass is shown in the chat as it happens, and the script ends with a clear compile status. You are no longer the person copying error messages between TradingView and a chat window.
Follow-ups change only the lines that need to change.
Ask a general chatbot to add one input to a 400-line indicator and you usually get 400 new lines back, with your comments gone and variables renamed. PineScripter edits the affected lines and leaves the rest of the script as it was.
The Code Changes view shows every edit side by side, and each version is saved in your script library, so you can compare or go back to any earlier one.
PineScripter Fine Tuned, or a model from the major labs.
Use PineScripter Fine Tuned, our own model, or models from OpenAI, Anthropic, xAI, Google and Alibaba. Every paid plan can use every model. Stronger models use credits faster, so you can pick a quick model for small edits and a stronger one for a complex strategy.
Whatever model you choose, it works with the Pine Script v6 reference manual as context and goes through the same compile checks.
Works with the scripts you already have.
Paste a script you wrote, one from a colleague, or an older v5 script. PineScripter can explain it, fix it, extend it, or upgrade it to v6. There is also a full code editor with error detection for the times you would rather type the change yourself.
Scripts and chats are unlimited on every plan, and your code is yours: copy or export any script whenever you like.
How it compares with a general chatbot
| Capability | General chatbots | PineScripter |
|---|---|---|
| Checks the script for compile errors before handing it over | No, you paste it into TradingView to find out | Yes, with a built-in lint engine |
| Fixes its own errors | Only when you paste the error back | Yes, automatically |
| Edits only the lines a follow-up changes | Usually rewrites the whole script | Yes, with a side by side diff |
| Works from the Pine Script v6 manual | Relies on training data | Yes |
| Runs the script on a chart | No | Yes, on 308 crypto markets |
Questions
How is PineScripter different from ChatGPT for Pine Script?
A general chatbot cannot tell whether the code it writes compiles, so you find out by pasting it into TradingView and copying the error back. PineScripter checks every draft with a built-in lint engine that works the way TradingView checks scripts, fixes the errors it finds on its own, and works from the Pine Script v6 manual. Follow-up requests edit only the affected lines, and you can run the script on a chart inside PineScripter.
What does "edits only what changes" mean?
When you ask for a change, PineScripter edits the lines that need to change instead of rewriting the whole script. Your comments, names and structure stay as they were, and the Code Changes view shows exactly what moved in each edit.
Does the AI always produce code that compiles?
It checks every draft and fixes what the checks find before handing the script over, so most scripts compile on the first paste. When it cannot resolve something, it says so instead of handing you broken code without comment.
Does PineScripter work with Pine Script v5?
PineScripter writes Pine Script v6, the current version. Paste a v5 script and it can upgrade it to v6 for you.
Can I bring my own existing Pine Script code?
Yes. Paste a script into the editor and PineScripter can explain it, debug it, add features, or upgrade it to v6. You can also edit by hand in the full code editor, which has error detection.
Which AI models can I use?
PineScripter Fine Tuned, our own model, plus models from OpenAI, Anthropic, xAI, Google and Alibaba. Every paid plan can use every model. Stronger models use credits faster.
How much Pine Script do I need to know?
None. Describe what the indicator or strategy should do in plain English and PineScripter writes the code and explains it. If you do know Pine Script, it still saves time on boilerplate, function signatures and targeted edits.
Write your first script
Describe the indicator you have in mind, or paste one you already have, and watch the AI plan, write, check and explain it.
