Keld Signal: AI usage in your browser

Keld Signal shows you how AI tools are used across your work, and what they cost.

Keld Signal shows you how AI tools are used across your work. This extension adds your Claude browser usage, so its usage sits alongside Claude Code and your other AI coding tools in Keld Atlas. Works with: Claude Chat, Cowork, Design, and Code at https://claude.ai. What it surfaces: • Number of prompts, replies and tokens per product, for today and the last seven days, in the toolbar. • Browser usage counted in Keld Signal the same way as Claude Code on your computer. • Clear status: whether the extension is connected, and whether your claude.ai account is the one Keld counts. Usage from other accounts is not counted. Private by design: • The extension reads only claude.ai and sends what it reads only to the Keld Signal app on your computer, never over the internet. • Keld Signal shares only usage figures (such as counts, lengths, models and tokens) and labels describing the kind of work. It does not send or store prompts or replies. Requirements: Keld Signal for Windows or Linux, signed in with the same account you use on claude.ai.
