I built a Chrome extension that puts AI tools on any text you select — define, simplify, translate, summarize without leaving the page

I built a Chrome extension that puts AI tools on any text you select — define, simplify, translate, summarize without leaving the page

Been working on this for a few months. The idea came from constantly having to copy text, open a new tab, paste it into ChatGPT, get the answer, go back. It breaks flow completely.

Mentra sits in your browser and when you select any text a small toolbar appears with:

  • Define — explains the word or phrase in context
  • Simplify — rewrites dense text in plain language
  • Translate — to your language
  • Summarize — condenses a long selection
  • Follow-up questions — ask anything about what you just read

Also has a popup for full-page summarization and key term extraction.

Just added Google sign-in so setup is about 10 seconds. Free to use.

Would love to know what's missing or what would make you actually keep it installed.

Solo project. Select any text on any page, small tooltip appears with actions. Uses Groq for inference so responses are fast. Context-aware — captures the surrounding paragraph so definitions are accurate to how the word is actually being used.

v1.1 just shipped with dark mode, keyboard shortcuts (Alt+D, Alt+S, Alt+T), follow-up questions, and a pause button.

Mentra — free to try, feedback welcome.
