Kontinuity

Track AI coding costs. Prevent context drift. Never lose the thread.

Kontinuity shows you how full your AI conversation's context window is, so you know when to start a fresh chat before answer quality drops. It works in Claude and ChatGPT, right in your browser. Kontinuity is free. Every feature is unlocked, with no trial and no account. WHAT IT DOES - Context health: a live meter of how much of the context window your conversation has used, with a clear nudge when it's time to start fresh. - Projects: tag conversations to a client or project and see activity and estimated cost per project. - Find a conversation: search your past chats by topic, title, or project. - Cost estimates: an approximate (≈) cost for today, this week, this month, and each session, in 18 currencies. These are estimates based on the text in your conversations, not your provider's bill. - Export your history as CSV or JSON. PRIVATE BY DESIGN Everything stays in your browser. Kontinuity has no servers, doesn't collect your conversations, and doesn't track you. NEW IN 0.9.35 - Kontinuity is now free for everyone, permanently. - Fixed: your own messages weren't being counted on claude.ai, which made input tokens show as 0. - Every cost and token figure is now clearly labelled as an estimate (≈).
