AI replies on X, in your voice
A free Chrome extension that drops a ✦ AI button on every post. Click it, get 3 replies in your voice, insert with one tap. Pick your model — Claude, ChatGPT, Gemini, Grok, DeepSeek, Kimi, or local Ollama — and bring your own key. Nothing touches our servers.
Bring your own key
Your key lives in your browser's local storage. Replies are generated by calling your chosen provider directly from your browser— there's no X-Autopilot backend, no analytics, and your key never leaves your machine.
Download & unzip
Grab the zip above and double-click to unzip. You'll get a x-autopilot-reply-helper folder.
Open Chrome extensions
Go to chrome://extensions and turn on Developer mode (top-right).
Load unpacked
Click Load unpacked and select the unzipped folder. Pin the extension from the puzzle-piece menu.
Pick a model + add your key
Click the extension icon, choose a provider (Claude, ChatGPT, Gemini, Grok…), paste that provider's key, describe your voice, and Save.
Use it on X
Open x.com, find a post, and hit the ✦ AI button in its action row.
Is it free?+
The extension is free. You pay Anthropic directly for usage with your own key — Claude Sonnet 4.6 is fractions of a cent per reply set.
Where does my API key go?+
Into your browser's local storage only. Reply generation calls api.anthropic.com directly from your browser, authenticated with your key. No X-Autopilot server is involved, ever.
Why isn't it on the Chrome Web Store?+
It's a developer-mode (load-unpacked) beta right now. Web Store publishing is coming; for now you load the folder yourself in 2 minutes.
The ✦ AI button isn't showing — why?+
X changes its layout often. Reload x.com; if it still doesn't appear, the extension's selectors may need an update. The Copy button always works as a fallback.
This is the manual version. X-Autopilot is the autopilot.
The extension suggests replies when you ask. X-Autopilot finds the right posts, writes the replies in your voice, and posts them on its own — all day, on your Mac.
