Definition
Rewind AI is a personal memory assistant application that continuously records what a user sees, says, and hears on their Mac, storing it locally and making it searchable so users can recall past meetings, browsing activity, or conversations in natural language. It later evolved into 'Limitless,' expanding toward wearable hardware for capturing conversations.
Overview
Rewind AI captures periodic screenshots of on-screen activity along with audio transcripts from meetings and microphone input, indexing everything into a locally stored, searchable timeline. Rather than manually taking notes or trying to recall which document contained a specific detail, users can search in natural language ('what did we decide about pricing last Tuesday?') and Rewind surfaces the relevant screen capture or transcript excerpt. A defining design choice was local-first storage: rather than uploading a continuous recording of a user's screen and audio to the cloud, Rewind processed and stored data on-device, addressing an obvious privacy concern inherent to always-on recording software. It used on-device compression and search indexing to make years of activity searchable without heavy cloud dependency, and offered summarization features like automatic meeting notes generated from recorded audio. The company later rebranded its consumer product direction toward 'Limitless,' pairing the software with a dedicated wearable pendant device designed to record and transcribe in-person conversations beyond just a single Mac's screen and microphone, extending the 'total recall' concept beyond the desktop. Rewind's core use case — building a searchable memory of everything you've seen or discussed — appeals to knowledge workers managing high meeting volume and information overload, though the always-on recording model raises real privacy and consent considerations, particularly around capturing other people's conversations and on-screen content without their explicit knowledge.
