Frequently asked questions

Is ToolBoost really free?

Yes. ToolBoost is a free online code editor with AI. You can write, run and refactor code without paying and without creating an account. AI features use free models through OpenRouter with a generous daily request quota.

Do I need to install anything?

No. ToolBoost runs entirely in your web browser — Chrome, Edge, Firefox or Safari, on desktop or phone. Open the page and start coding.

Which programming languages can I run?

You can run JavaScript, Python, HTML and CSS directly in the browser, with syntax highlighting for many more languages including TypeScript, C++, Java, Go and Rust.

How is ToolBoost different from GitHub Copilot or Cursor?

ToolBoost gives you Copilot-style ghost-text autocomplete, Ctrl+K inline AI edits and an AI chat assistant, but in the browser and for free — no desktop app, no subscription.

Can I code on my phone?

Yes. The editor is mobile-friendly, so you can write and run code on Android or iPhone. Dalam Bahasa Indonesia: ToolBoost bisa dipakai untuk coding di HP secara gratis.

Is my code saved or shared?

Your files stay in your browser. You can upload files, download them, or export your whole project as a .zip at any time.

⚠️

Enable Local Terminal?

This feature connects ToolBoost to a small program (a "companion app") that runs on your own computer. Once connected, ToolBoost can run any command on your computer — exactly as if you typed it into a terminal/command prompt yourself.

Before continuing, make sure you understand:

• Commands you or the AI run through this Terminal have full access to the files & system on your computer — nothing is sandboxed.

• Only enable this if you trust the ToolBoost page you currently have open.

• The connection token is secret — never paste or share it anywhere else.

• You can disconnect at any time, and the companion app only runs while you keep it running.

I understand the risk and trust this page to run commands on my computer.
