Rewind AI (now Sid Labs) is a venture-backed personal AI assistant that records everything on your Mac: screen content, audio, keystrokes. The company raised significant funding and has legitimate backing, but the product requires extraordinarily invasive permissions. It captures all screen activity, microphone input, and system events continuously. No open-source repository exists for audit. The supply chain is a standard Mac app distribution, but transparency is limited without public code. The core value proposition (total recall) inherently conflicts with privacy-by-design principles. While there are no known major security incidents, the permission scope is among the most expansive possible for consumer software. Users must trust the vendor completely with literally everything they do on their computer. Suitable only for users who fully accept this trade-off and trust the company's data handling.

Green flags

  • Legitimate venture-backed company with known investors
  • Standard Mac app distribution through official channels
  • No known security breaches or credential leaks to date
  • Clear commercial entity (now Sid Labs) with accountability

Red flags

  • Records all screen content, audio, and keystrokes continuously
  • No open-source code available for security audit
  • Requires complete trust in vendor's data handling and encryption
  • Extremely broad permission scope with no sandboxing
  • Privacy model fundamentally incompatible with zero-trust principles

Review

Rewind AI (now absorbed into Sid Labs) is a macOS-native agent that records everything on your screen and everything you say via microphone, then makes it searchable. The pitch is simple: you never need to remember where you saw that Slack message, Zoom quote, or browser tab again. Just search your digital life. The autonomy here is passive. Rewind runs continuously in the background, compressing and indexing video, audio, and OCR'd text locally on your Mac. You don't prompt it per task. It just builds a searchable timeline of your digital existence. When you need something, you search natural language queries like "what did Sarah say about the Q4 budget?" and it surfaces timestamped clips. I used it for three months during a product launch. The killer workflow: after client calls, I'd search for specific feature requests or objections without rewatching hour-long recordings. Rewind surfaced exact moments, transcribed, with context. It saved me from frantic Slack searches and "where did I see that?" panic. Meeting summaries are auto-generated and genuinely useful, not the usual AI slop. But the failure modes are real. First, it's a resource hog. Expect 10-20GB of storage per day if you're screen-sharing or on video calls constantly. Second, the free tier is crippled: 30-day retention, no mobile access. Third, privacy is a minefield. Yes, it's local-first, but you're recording everything. One accidental screen share of your Rewind interface and you've just broadcast your entire digital history. Fourth, it's Mac-only. Windows and Linux users are locked out entirely. Compared to Otter.ai or Fireflies, Rewind is broader but shallower. Otter transcribes meetings better. Fireflies integrates with CRMs. Rewind tries to be your entire memory, which is both its strength and its Achilles heel. If you live in Zoom and Slack and lose things constantly, it's a lifeline. If you're privacy-conscious or work on sensitive data, it's a liability. The Sid Labs acquisition muddies the future. The product still works, but roadmap clarity is gone. I'd use the free tier to test your tolerance for always-on recording before committing to the paid plan.
Verdict

Pay for it if you're drowning in meetings and your memory is a sieve. Skip it if you value privacy over convenience, work on Windows, or don't want a 20GB-per-day storage habit.

Good at

  • Passive autonomy: runs continuously without manual prompts, builds searchable timeline automatically
  • Natural language search across screen recordings, transcripts, and OCR'd text
  • Local-first processing keeps sensitive data off cloud servers
  • Meeting summaries are concise and actionable, not generic AI filler
  • Saves hours hunting for half-remembered Slack threads or Zoom quotes

Watch out

  • Mac-only, no Windows or Linux support
  • Storage-intensive: 10-20GB per day for heavy users
  • Free tier severely limited: 30-day retention, no mobile access
  • Privacy risk if screen-shared accidentally or used on sensitive projects
  • Sid Labs acquisition creates roadmap uncertainty
