“A desktop productivity agent which tracks what you do in a day and gives you a reality check on how productive you actually are.”

“You want an app to confirm what you already know: you spent 4 hours on Reddit calling it 'research.'”
An always-on desktop agent that monitors app usage, browser tabs, meeting time, and idle periods — then delivers a brutally honest daily productivity report with AI-generated insights and shame.
This exists in multiple flavors, from lightweight time trackers to full screen-recording AI. The core feature set is solved. Where nobody has nailed it is the 'reality check' framing — brutally honest, personality-driven feedback rather than boring pie charts. That emotional angle is your only differentiator in a market drowning in dashboards.
