Headroom

Browser extension that shows a real-time gauge of AI chat context window usage

Browser extensionfreeglobal

Headroom is a browser extension that shows a real-time, color-coded gauge of context window usage during AI chat conversations, so a user knows before the AI starts losing earlier context. It requires no account or setup, breaks down token usage per exchange, and reads conversation text only transiently to count tokens — no Headroom server is involved, and only token counts are stored, locally by default.
