Rewind AI
Personal AI memory app that recorded and searched your digital activity, now defunct.
Rewind, rebranded Limitless, ran out of road as Microsoft and cheaper models copied its core feature for free, and Meta bought the team, not a business.
Rewind AI made software that recorded and summarized your conversations and screen time so you could search through it later. The problem was that the core pieces, recording, transcription, and summarization, were becoming cheap and standard features in AI models, and Microsoft built similar technology (called Recall) directly into Windows, meaning big companies could copy the idea for free. Once Meta bought the company in December 2025, Rewind stopped existing as an independent product; today the brand name is being used by unrelated websites, so any offer claiming to be from Rewind AI or Limitless is either a scam, a leftover from old investors with worthless stakes, or a feature buried inside Meta's Ray-Ban glasses.
Any new offer or app branded 'Rewind AI' or 'Limitless' appears online. Would likely be brand squatting or scam since the original entity ceased operating December 19, 2025.
Microsoft Recall usage or adoption figures reported in Windows telemetry or press. Would show the OS-level feature that helped displace Rewind is being used by former target customers.
- Shut down Dec 19, 2025, two weeks after acquisition
- Raised $33M total, sold for undisclosed sum
- ARR only ~$2M in April 2025 vs Gong's $285M
- Company no longer exists as an independent entity; fully absorbed and shut down by Meta as of Dec 19, 2025.
- Core product commoditized by foundation models and free OS-level features like Microsoft Recall.
- rewind.ai domain now squatted by unrelated third party, creating brand confusion and scam risk.
- Undisclosed Meta acquisition terms suggest modest exit relative to $350M 2023 valuation, likely poor returns for investors and equity holders.
| Rival | Direction | Evidence |
|---|---|---|
| Microsoft | losing to | Windows Recall shipped free at OS level, replicating Rewind's core concept, 2024 |
| Gong | losing to | Gong's $285M ARR in 2023 dwarfed Limitless's roughly $2M by 2025 |
| Screenpipe | losing to | Open-source rival marketed itself as 'best Rewind alternative' with offline capture, Feb 2026 |
| Meta | losing to | Acquired Limitless and absorbed team into Reality Labs, Dec 5 2025 |
| Humane | contesting | Fellow AI-hardware startup also collapsed, IP sold to HP for $116M, Feb 2025 |
- Is Rewind AI still in business?
- No. Rewind rebranded to Limitless in April 2024, was acquired by Meta on December 5, 2025 (terms undisclosed), and the product fully shut down on December 19, 2025, with the team absorbed into Meta's Reality Labs division.
- Who owns Rewind AI now?
- Meta Platforms owns the technology and team as of December 5, 2025, having acquired Limitless (formerly Rewind AI) and folded its staff into Reality Labs to work on AI wearables like Ray-Ban Meta glasses.
- Was Rewind AI (Limitless) profitable?
- No. Estimates put annual revenue around $2M by April 2025, far below its $350M Series A valuation from May 2023, and Meta's December 2025 acquisition terms were undisclosed, suggesting a modest financial outcome.
- Could AI replace what Rewind AI built?
- It already did. Microsoft's free, OS-embedded Recall feature and cheaper foundation models for transcription and summarization eroded Rewind/Limitless's core value proposition before Meta acquired and shut down the product on December 19, 2025.
- Is rewind.ai a legitimate site today?
- No, as of mid-2026 the rewind.ai domain is operated by an unrelated third party running a free AI-tools aggregator site with no connection to the original founders, Limitless, or Meta, so any 'Rewind AI' offer there should be treated as unaffiliated.
- Who was Rewind AI's biggest competitor?
- Microsoft's free Recall feature on Copilot+ PCs directly replicated Rewind's original screen-recording concept at the OS level, while enterprise player Gong reported $285M ARR in 2023 versus Limitless's roughly $2M, showing the scale gap.
