Developer builds Jev Bookmarks to start Jev from Chrome history

The developer's starting point was testing Jev-ultrafast and Jev's Computer Use after seeing them shared on X. The browser felt noticeably fast, which raised the question of where that speed actually helps. Two cases emerged: unfamiliar sites where the AI must explore, and known destinations the AI is asked to open repeatedly during development.

Building the Books accounting app tied to マネーフォワード made the second case concrete, as the AI frequently reopened screens like the fixed-asset ledger and tax filing pages. Since those URLs often sit in Chrome history, the developer had Jev choose a starting page rather than letting it operate blindly. The design sends only narrowed candidates to Jev, keeping full history and query strings out of the entry decision, and pages judged useful after an operation are saved per project for reuse.

The developer also noticed Jev can evaluate several viewpoints at once, as described in TypeSafe's documentation. The current Jev Bookmarks picks a single entry, but keeping three candidates for the next step may be possible. Whether this approach pays off hinges on how often saved pages match a new request, since no time-based measurement was recorded.
