Description
Automatically stamps your message with the local send-time when you type into a supported LLM chat composer. Automatically inserts a timestamp — [2026-07-07 14:32] — at the start of your message the moment you begin typing into a supported LLM chat composer, then keeps it current until you send, so the LLM sees your send-time, not the time you started drafting. Works on Claude, ChatGPT, Gemini, and Copilot (web), in Chrome, Edge, Firefox, and Safari (macOS). Format [YYYY-MM-DD HH:mm] — local time, 24-hour When Once, on the first keystroke into an empty composer Live Refreshes once a minute until the message is sent Sites claude.ai, chatgpt.com, gemini.google.com, copilot.microsoft.com What it does (behavior) Stamp on first keystroke into an empty composer — before your first character lands. Exactly once per message. Live send-time. While the message sits unsent, the stamp refreshes every 60 seconds. Draft for 5 minutes and the LLM still receives your send-time. The refresh is length-preserving, so your caret never jumps and typing is never interrupted. Hands off if you touch it. Edit, move, or delete the stamp yourself and live updates stop for that message — it is never silently re-inserted. Resets after send. When the composer empties (send, or you clear it), the next message gets a fresh stamp. Shift+Enter (newline) does not reset. Composer only. Search boxes and settings fields are never stamped.
