Otter joins your call. Driffle stays out of it.
Otter is a mature transcription service with a long compliance record. The trade is a bot in the room and your transcripts in the training set.
The short version
Otter has been doing transcription longer than most, holds SOC 2 and HIPAA reports, and works across Zoom, Teams and Meet on every device. For regulated buyers who need paperwork today, that record matters.
The cost is visible. Otter joins the meeting as a participant, so everyone sees a notetaker in the room. Driffle listens on your Mac and nothing appears in the call.
Otter's privacy policy says it trains its AI on de-identified recordings and transcriptions, and states no opt out. Driffle does not train on your work in any form.
Where we are the same
Worth saying plainly, because a comparison that pretends the other tool is bad is not much use to you.
- Both produce a searchable transcript with a summary and action items.
- Both let you ask questions across past conversations rather than reading transcripts.
- Both store customer data with AWS in the United States.
- Both offer a free tier to try before paying.
Where Driffle is different
Nothing joins the call
Otter enters your meeting as a participant, which every attendee can see. Driffle listens on your machine, so a sensitive conversation does not get a visible notetaker.
Your transcripts stay yours
Otter states it trains its AI on de-identified recordings and transcriptions, with no opt out described. Driffle never trains on your work, and the models run inside our own AWS account.
Memory past the transcript
Otter remembers what was said. Driffle also remembers the document you were reading and the thread you replied to, so answers are not limited to the call.

Switching
Turn off Otter's auto-join for one week and let Driffle cover the same calls. Watch two things: whether anyone mentions the missing bot, and whether you can still answer a question about a decision a week later.

Common questions about Driffle and Otter.ai
Does Otter put a bot in the meeting?
Yes. Otter joins Zoom, Microsoft Teams and Google Meet as a participant, so attendees see a notetaker in the room. Driffle listens on your Mac and nothing joins the call.
Does Otter train AI on my conversations?
Otter's privacy policy describes training its AI on de-identified audio recordings and on transcriptions, and does not describe an opt out. Driffle does not train on your work at all.
Is Otter more compliant than Driffle?
On paperwork today, yes. Otter's trust centre lists SOC 2, HIPAA, GDPR, CCPA and VPAT reports. Driffle's SOC 2 Type 1 audit is underway with Type 2 to follow, and we do not sign BAAs yet. If a current report is a purchase requirement, Otter clears that bar and we do not.
What does Driffle capture that Otter does not?
The work around the meeting. Documents, threads and screen context, so a question about a decision can draw on what you were reading as well as what was said.
Which is cheaper?
They are close. Otter Pro is $16.99 a month or $8.33 billed annually, and Business is $30 or $19.99 annually. Driffle Plus is $17 a month billed annually, $20 monthly, and the free plan never expires.
Can I use Driffle on Windows or Android?
Not today. Driffle ships for Mac on Apple Silicon and Intel, with Windows and Linux available by request. Otter runs on web, Mac, Windows, iOS and Android.
