Where did your time go? When a workday slips by, a quick voice check-in helps you remember what happened. Time Study turns each recording into an editable transcript and keeps your check-ins in a simple timeline. Choose reminders every 15, 30, or 60 minutes during the hours you set. They follow your current time zone. Snooze them for two hours when you need space. If transcription does not finish, your recording stays available for Retry. After a transcript saves, the recording is removed. Export your complete timeline as one dated JSON file to review with an AI assistant of your choice. No account required. Free to use.
