Spotrum vs Otter.ai
Otter listens to your meetings; Spotrum hosts them. That difference decides everything downstream — how recording works, what the transcript is worth, and who holds your data. The honest split:
A polished transcription companion: drop its bot into a Zoom, Meet or Teams call and get live notes, summaries and action items. As an add-on to someone else's meeting stack, Otter does its job well.
Side by side
No bot in the room
Otter joins your call as a third-party bot with its own access. Spotrum records natively — the platform hosting the call captures it server-side, with the host's one tap and everyone's awareness.
A transcript that can testify
Otter notes are editable text in an app. Spotrum seals the speaker-named transcript and summary into a PDF with a cryptographic signature — verifiable by QR at spotrum.com/verify.
Recordings under EU law
Otter is a US service processing your meetings in the US. Spotrum hosts and records your calls on EU servers; AI transcription is opt-in, via a named provider under Standard Contractual Clauses — and E2EE rooms exist for what should never be recorded at all.
A whole platform, not a plugin
Voice, video, walkie channels, a live map, events, files — the meeting and its record live in one place, with one bill and no glue between vendors.
If you're happy in Zoom or Meet and just want notes, Otter is fine. If the conversation itself should produce a verifiable record — host it on Spotrum and skip the middleman.
