FeedEnglish

Chrome extension that passively collects vocabulary from your English browsing

Problem

Learners want to pick up English from daily browsing, but highlighting words is easy to forget and disrupts reading; translation tools only give instant meaning, not retention. Existing vocabulary apps require active effort and are hard to stick with.

Solution

Chrome extension: automatically collects potentially unfamiliar words on 74+ popular English sites using a local AI model, fully passive; highlights collected words on revisit; spaced-repetition review UI; local-first for privacy.

Users

Developers, designers, and students who browse English content and want to improve vocabulary

MVP

Auto-collect vocabulary on supported sites; highlight collected words; basic review cards with local storage; simple familiarity marking

Revenue

Free basic; premium (multi-device sync, export, unlimited review) at $3.99/month or $29/year

Why now

Lightweight in-browser AI models are mature enough to filter vocabulary without uploading data; English learning is a persistent need and existing tools lack passive collection
