Pros & cons
Granola
Pros: Captures system audio without joining as a meeting bot — works for any meeting tool without admin rules; enterprise tier opts out of model training.
Cons: Mac/iOS only — no Windows/Linux story; cloud processing despite local-audio claim.
Limitless
Pros: Local-first lifelog architecture (originated as Rewind) is privacy-stronger than competitors; Meta acquisition gives it deep funding.
Cons: Recent platform pivot from Rewind macOS; product direction post-acquisition uncertain.
