Give your AI a sense of time.
Local time context for AI chat interfaces — date, exact time, timezone,
session length, and time elapsed since your last message. 100% local — zero
network requests, verifiable in this codebase (grep -r "fetch(" src/
returns nothing).
Works with ChatGPT, Claude, Gemini, Mistral, Perplexity, and Grok out of the box, plus any other web AI interface (including local ones like Open WebUI, Ollama, and LM Studio) via the opt-in Free Wrist.
Status: Calibre 1.0 — GM. Shipping as "AI-Watch Clock" on the Chrome Web Store and Firefox Add-ons; source and releases live here.

npm run build && npm run build:firefoxSee docs/ARCHITECTURE.md. Key invariants: display
name centralized in src/shared/brand.ts, dials are themes only,
generic-first adapters, zero network, honest injection.
No data collection, no network requests, nothing leaves your device. See
src/shared/brand.ts and the content scripts in src/content/ for the
full injection logic — there is nothing else to audit.
