Clarity

Block ChatGPT, Gemini, Claude & more. Focus timer with full-screen countdown, custom blocklist, and private on-device usage stats.

Clarity helps you control your use of AI chat tools by blocking and/or tracking usage. Choose Block for timed focus sessions, Track for private on-device analytics, or use both. Works with ChatGPT, Gemini, Claude, Copilot, Perplexity, and any sites you add. PRIVACY & PERMISSIONS We do not collect, transmit, or sell personal data.
