Feature-by-feature
Userdoc focuses on generating structured requirements: it reverse-engineers source code into functional specs (Code-to-Docs), extracts specs from screenshots or Figma designs (Image-to-specs), and creates user stories from plain language. It also builds epics, personas, acceptance criteria, non-functional requirements, and dataflow diagrams. Integrations include Cursor, GitHub Copilot, Claude Desktop, Linear, Asana, and Trello. Pieces for Developers is a passive recorder: it captures keystrokes, app activity, and audio (opt-in) every 2 seconds from 25+ apps into a searchable timeline. Its LTM-2.5 engine keeps memories on-device for 9 months. You can search by natural language and get daily/weekly summaries. It integrates with Chrome, VS Code, JetBrains, Slack, etc., and its MCP Server feeds AI assistants like Claude and Copilot. While Userdoc exports to CSV/JSON, Pieces offers privacy controls (pause, delete, app-level disable) and time tracking for billable hours.
Pricing compared
Both tools are freemium. Userdoc offers a free tier (likely limited output), but specific paid prices are not listed. Pieces for Developers provides a free individual tier storing 9 months of history; beyond that, team/enterprise pricing is unknown. Userdoc's value is in replacing manual BA work (quote: 87% cost savings), while Pieces’ value is in automatic memory indexing. If you need to standardize specs across a team, Userdoc may justify a paid plan. If you want individual workflow recall, Pieces’ free tier could suffice indefinitely. Neither discloses full pricing, so you’ll need to check their websites for upgrades.
