Company profile
researched Aug 2026Limitless AI, Inc. develops AI-powered personal memory tools built around continuous capture of audio and screen activity. The company originated as Rewind AI, whose 2022 Mac application recorded and indexed everything a user saw or heard on their computer, applied OCR and heavy compression, and allowed the archive to be searched with natural language. In April 2024 the company rebranded to Limitless and shifted its focus to a $99 wearable Pendant, a microphone-equipped necklace that records in-person conversations and surroundings, with the Mac app moving to a cloud-connected architecture and screen recording becoming secondary to meeting transcription.
The consumer product line pairs the Pendant with mobile, desktop and web apps. The companion Android app, marketed as Pendant Lifelog / Limitless AI Voice Recorder, provides AI transcription, meeting and conversation summaries, AI-powered search and chat over transcripts, daily recaps with productivity statistics and task reminders, offline recording, export of transcripts to notes apps, email or LLMs, and cross-device sync across iPhone, desktop and web.
In December 2025 Limitless announced it had been acquired by Meta, with the team joining the wearables organization inside Reality Labs to work on AI-enabled wearables as part of Meta's stated "personal superintelligence" vision. Pendant sales ceased, existing Pendant customers were promised at least one more year of support and moved to a free Unlimited Plan, non-Pendant functionality such as Rewind was sunset, and data export and deletion tools were released.

Service became unavailable in Brazil, China, the European Union, Israel, South Korea, Turkey and the United Kingdom, with affected users given until December 19, 2025 to export data before account deletion.

Rewind launched as a local-first Mac app offering always-on screen capture, OCR and AI-powered search, using a compression system the company said could reduce more than 10GB of recorded data to under 3MB.
