About Rewind AI
Rewind AI was founded in 2020 by Dan Siroker (former CEO of Optimizely) as a personal search engine for your digital life. The original Rewind app for Mac could record and search everything you saw, said, or heard on your computer - creating a searchable memory of your entire screen history.
In April 2024, the company rebranded to Limitless and pivoted to focus specifically on meeting capture and conversation intelligence. Limitless introduced a wearable hardware device called the Pendant alongside a cloud-based AI meeting assistant. The company raised over $25M from investors including Andreessen Horowitz (a16z) and NEA, reaching a $350M valuation in 2023.
In December 2025, Meta acquired Limitless to build what they called "personal superintelligence" wearables. The original Rewind Mac app has been discontinued, and the Pendant is no longer sold to new customers, though existing users receive free Unlimited plan access for at least one year.

Customers & Case Studies
Target Users
Limitless primarily served prosumer knowledge workers, executives, consultants, and professionals who attend frequent meetings. The product was popular among startup founders, venture capitalists, sales professionals, and anyone who needed to recall details from conversations.
User Success Stories
Users with 5+ meetings per day reported saving 2-3 hours weekly on note-taking and meeting follow-ups by using AI-generated summaries.
Sales reps used the "Ask Limitless" feature to instantly recall specific details from prospect conversations, improving follow-up quality and deal progression.
Investors used Limitless to capture every pitch meeting and due diligence call, creating a searchable archive of all founder interactions and company research.
Professionals with high client interaction volumes used the Pendant for in-person sessions, generating transcripts and action items automatically.
Use Cases by Vertical
Pain Points & Solutions
Knowledge workers attend 15-25 meetings per week. Limitless captures everything so you can focus on the conversation instead of frantically taking notes.
Critical details from meetings are forgotten within hours. The AI creates searchable transcripts and summaries so nothing falls through the cracks.
Moving between meetings without context is jarring. Meeting Prep briefs automatically surface relevant history from previous interactions with attendees.
Virtual meeting tools capture online calls but miss in-person conversations. The Pendant bridges this gap, recording face-to-face interactions seamlessly.
Visible meeting bots create awkward dynamics with clients. Limitless captures audio at the device level, so no bot joins the call and participants are not disrupted.
Writing meeting recaps and action items is tedious. AI-generated summaries and action items are ready immediately after each meeting ends.
How Rewind AI Looks on AI Platforms
Rewind AI's score reflects moderate AI readiness. The website has been simplified following the Meta acquisition, with reduced product documentation, limited pricing transparency, and fewer structured data elements. The original Limitless site had stronger SEO and content depth.
How accessible is Rewind AI?
Following the Meta acquisition and rebrand, the rewind.ai domain redirects or serves minimal content. The original Limitless site (limitless.ai) had comprehensive product pages, help center articles, and FAQ sections. Current accessibility for LLMs is limited compared to pre-acquisition levels due to reduced web presence.
How easy is it for LLMs to understand Rewind AI's mission?
The core mission - giving people a "perfect memory" through AI - is well-documented across tech press, Product Hunt, and third-party review sites. However, the current state of the product (acquired, partially discontinued) creates ambiguity for AI systems trying to assess whether the product is actively available.
Competitive Landscape
How Rewind AI / Limitless compares to competitors in the AI meeting and memory space:
| Competitor | What Differentiates Limitless | Key Trade-Off |
|---|---|---|
| Otter.ai | Wearable pendant for in-person capture; no visible meeting bot | Otter has broader enterprise adoption and team features |
| Fireflies.ai | Device-level recording without bot; hardware + software combo | Fireflies has deeper CRM integrations and sales intelligence |
| Recall.ai | Consumer-focused with simpler UX and wearable option | Recall.ai offers meeting bot infrastructure for developers |
| Krisp | Broader capture scope (meetings + in-person); AI search across history | Krisp excels at noise cancellation and audio quality |
| Notion AI | Dedicated meeting capture with automatic transcription | Notion AI is part of a broader workspace and note-taking platform |
| Granola | Hardware pendant for in-person capture; longer meeting history | Granola focuses on enhancing your own notes during meetings |
| Fathom | No visible bot approach; captures in-person via Pendant | Fathom is free for individuals and has strong Zoom integration |

Security & Compliance
Limitless built its "Confidential Cloud" infrastructure with security as a core feature. All data is encrypted at rest using 256-bit AES encryption with Hardware Security Modules (HSM), and in transit using TLS 1.3. The company maintained SOC 2 Type II compliance and conducted regular penetration testing. Data sent to third-party AI providers for transcription was not used for training and was deleted after 30 days.
Following the Meta acquisition, privacy-conscious users expressed concerns about data handling under Meta's ownership. Limitless previously operated with a minimal data access policy, only accessing customer data for debugging with explicit permission.
