Otter.ai is voice notes and meeting transcription and Rabbit r1 is AI hardware device. We compared both — and added Lucy OS1 to the mix so you can see the full picture.
TLDR:Otter.ai and Rabbit r1 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.

Both Otter.ai and Rabbit r1 are solid for their core use cases; Lucy OS1 is the alternative if you want an AI that genuinely knows you.
