Highlights
- Splits the page into short passages, keeping each section heading as context, and scores what is on screen first, 8 passages per request.
- Matches are highlighted on the page and marked on the scrollbar; passages that do not answer stay unmarked, so it says so when nothing fits.
- Measured on real pages including Wikipedia and a long Hacker News thread: 0.4 to 0.9 seconds and $0.0005 to $0.007 per search.
- In testing the top result answered the question for 15 of 15 clean pages and 19 of 20 messy ones like comment threads and recipe blogs.
- It matches meaning rather than words: the README's example finds the reader comment about substituting eggs for can I make this without eggs?
Watch out
Grounded on the full repo README and GitHub metadata read on 2026-10-15. The testing figures (15/15 and 19/20) are the author's own, described as done in testing without a published protocol; the extension needs your own TypeSafe API key, and the install note says new accounts may need to join a waitlist.
Questions about this entry
Short answers drawn from the linked project or page.
An open-source Chrome extension that asks a web page a question and jumps to the passages that answer it. It highlights the matches on the page and marks them on the scrollbar, so you can move between the answers instead of skimming the whole text.
It matches meaning, not words. The README's example: can I make this without eggs? finds the reader comment about substituting eggs, where Ctrl+F for eggs finds only the recipe's ingredient list.
Smart Find splits the page into short passages, keeps each one's section heading as context, and has Jev score every passage against your question in parallel, 8 passages per request, starting with what is on screen.
Measured on real pages: 0.4 to 0.9 seconds per search and $0.0005 to $0.007 depending on page length. You pay TypeSafe directly for the Jev calls; there is no server of the author's in between.
In the author's testing the top result answered the question for 15 of 15 clean pages and 19 of 20 messy ones such as comment threads, recipe blogs and terms of service. Passages that do not answer stay unmarked, so it tells you when nothing fits.
Clone or download the repo, open chrome://extensions, turn on Developer mode, choose Load unpacked and pick the extension folder, then paste your TypeSafe API key into the page that opens. The quickstart notes new accounts may need to join a waitlist.
The API key is stored only in your browser, and page text is sent to TypeSafe's Jev API only when you run a search, never in the background. The README states there is no server of the author's in between.
