ChronoNav: a Chrome extension to jump back in long Gemini chats
When using Gemini for long research or , finding something from earlier in the conversation becomes surprisingly hard once it passes about 30 turns. Manually scrolling is clumsy and often leads to re-asking questions or wasting time hunting for a message. ChronoNav is a built to fix exactly this.
It adds a clickable timeline alongside the Gemini chat interface, letting a user instantly jump to an earlier point in the conversation. It does not summarize or save anything — it is purely a navigation tool. It also includes an optional 'Time Context' toggle, off by default, that adds the local time and UTC offset to every prompt sent to Gemini.
This addresses the fact that Gemini often has no real sense of what 'earlier today' means without that extra context. The extension is available for free on the .
