Otter.ai vs Fireflies.ai

On what the policies say, Fireflies.ai is the better choice for your data: graded B against Otter.ai's F.

Grades read the plan most people are on. Each company's full entry has every plan, every clause and the archived copy it was read from.

Otter.ai

Otter trains its AI on your recordings and transcriptions. The policy says the audio is de-identified but concedes the transcripts may still contain personal information.

Verdict

By default: Trains on you by default
The way out: No opt-out in the policy
What F means: On by default, with no way out on the plan you are on — and nothing short of reading the terms would have told you.
Last checked: 5 Oct 2026

Fireflies.ai

Fireflies records your meetings and says it does not use that content for AI training — and contractually stops its vendors doing so either.

Verdict

By default: Does not train on you by default
The way out: No opt-out in the policy
What B means: Off by default. Training happens only if you opt in, or not at all.
