Opening excerpt (first ~120 words) tap to expand
Headroom Know when your AI is about to forget. English | 简体中文 Headroom is a browser extension that gives you a real-time, visual gauge of your context window usage in AI chat conversations — so you know before the AI starts forgetting. Features Zero setup — No account, no API key, no configuration. Install and it just works. Real-time gauge — Watch your context window fill up as you chat. 🟢 Green (plenty of room) · 🟠 Yellow (filling up) · 🔴 Red (time for a new conversation). Per-round breakdown — See estimated token counts for every Q&A pair, input and output separately. Privacy by design — Conversation text is read transiently to count tokens, then discarded. Only the token counts are stored, locally and optionally in your own cloud storage. No Headroom server exists.
