AI assistants can tell the time when asked—but they don't naturally understand the temporal context of a conversation. AI-Watch is a free, open-source browser extension that gives ChatGPT, Claude, Gemini, Grok, Mistral and other AI assistants the context they naturally lack: local time, timezone, session duration and time since your last message. 100% local. No account. No tracking. No telemetry. And yes... you can even ask your AI what it thinks about the watch you just gave it.
