Pieces
Pieces runs in the background on your computer forming a searchable memory of your work, capturing what you see and what you copy by default and what you hear only if you opt in. It builds a chronological timeline across Gmail, Outlook, browsers and Slack, and generates standups, briefs and recaps from real context.
- Solves a problem everyone has and almost nothing addresses
- The capture split is drawn at the line people actually care about
- Making audio opt-in while screen content is default is the right way round
- A timeline answers what happened, which search cannot
- Continuous screen capture is a large permission that deserves real thought
- Records what you saw, not what you understood, which can mislead
- Cannot capture what happened without you, which is often what matters
