Decision models

Sell a Chrome extension that hides posts readers don't want

Build a browser extension that uses a decision model (a fast AI that only makes yes/no or sorting calls) to mark or hide posts a reader doesn't want, such as likely AI-written ones, on sites they scroll every day. Readers pay a monthly fee for a cleaner feed.

The hard part: making the hide calls fast and accurate enough that readers trust them, then getting found in a crowded Chrome Web Store.

Who pays

Readers pay a monthly subscription to have unwanted posts flagged or hidden as they scroll. One poster reports paying $20/mo for a similar extension that flags likely AI posts, but no source reports revenue for this exact product, so any price you set is a suggestion.

How to build it

  1. Let readers set their rules

    Build a simple settings screen where readers describe in plain words what they like and what they want gone, such as likely AI-written posts or a topic they are tired of.

  2. Build the extension

    Use Claude Code or Cursor to build a Chrome extension that reads each post as it appears on the page and either adds a small label or hides it.

  3. Add the yes/no check

    Send each post and the reader's rules to a decision model such as Jev for a quick yes/no call on whether to hide it. Run the calls through a small server on Vercel so your key stays private.

  4. Test on real feeds

    Scroll X and other busy sites with 50-100 posts you have already labeled yourself and check how often the extension agrees. Adjust the wording of the rules until results look right.

  5. Charge a monthly fee

    Give a short free trial, then charge a monthly subscription through Stripe or ExtensionPay. Publish to the Chrome Web Store with a short demo video.

    paoloanzn reports building a Chrome extension called wilwid (what-i-like-what-i-don't) with Opus 5.5 and the Jev model. The poster says you tell it what content you like and hate, and it removes the unwanted content from every page in real time.

    ptrschmdtnlsn says paying $20/mo for Pangram's Chrome extension turned out to be a good purchase. In the poster's view, Twitter is noticeably better with a small label showing whether posts are probably AI, so they can scroll past the AI ones right away.
