Rewind AI is screen recording and memory AI and Perplexity AI is AI search engine. We compared both — and added Lucy OS1 to the mix so you can see the full picture.
TLDR:Rewind AI and Perplexity AI are both capable tools in their respective categories. Neither offers persistent cross-session memory, automatic calendar and email awareness, or the always-on working presence that modern knowledge workers need. Lucy OS1 was built specifically for this gap — it remembers your context across every session, reads your live calendar and inbox, and stays present alongside your work. Both Rewind AI and Perplexity AI are solid for their core use cases; Lucy OS1 is the alternative if you want an AI that genuinely knows you.
