Timegpt

TimeGPT shows you when every ChatGPT message was sent and when each conversation was created — information that exists in the API but ChatGPT's UI hides from you.

Features:
- Timestamps on every message, both yours and the assistant's
- Timestamps on conversations in the sidebar
- Live timestamps that appear as messages stream in
- Multiple formats: relative ("5 min ago"), 12/24-hour clock, date and time, ISO 8601
- Adapts to ChatGPT's light and dark themes
- Dates and times are localized to your browser language

Privacy:
TimeGPT reads timestamp data from ChatGPT API responses already happening in your browser. Your format preference is stored locally using Chrome's sync storage. No data is collected, transmitted, or shared with any third party.
