Pick Otter if you want your Zoom, Google Meet or Teams calls recorded, transcribed and summarised automatically, with follow-ups. Pick Rev if you need transcripts a human has checked, such as legal, court or caption work with a stated turnaround. Most readers will only need one of these, because they solve different problems.
People type this pair into Google as if they're two flavours of the same thing. They're not. One is now a legal and investigative platform that also sells human-checked transcripts. The other is an AI that sits in your meetings and takes notes. So the first question isn't which is better, it's which job you've got.
Our verdict in a sentence each
If your problem is meetings, go with the AI notetaker: it records and transcribes Zoom, Google Meet and Teams in real time and hands you a summary. If your problem is a recording that has to be right, such as a deposition, an interview for a court case or captions a viewer will rely on, go with the human-verified service. Very few readers need both, and neither replaces the other.
A transcription brand that now leads with legal evidence
If you last looked at Rev a few years ago, its home page will surprise you. It no longer reads as a general transcription site. It calls itself an Investigative Intelligence Platform and puts legal evidence analysis first: multi-file evidence analysis, a document editor, image analysis and templates. Its site also says SmartDepo is now part of Rev Legal.
The human services are still there. You'll find Human Transcription, Human Captions, legal drafts and court reporting on the menu, and the vendor says its human transcription is 99%+ accurate and guaranteed in 12 hours or less. But the audience it speaks to first is criminal prosecution, defence, law enforcement, civil law and court reporting agencies, with research, newsrooms and education further down.
Otter, by contrast, is built around everyday meetings. That's why the two are less direct rivals than the search term suggests.
How they line up
| What you're weighing | Rev | Otter |
|---|---|---|
| Main product | Investigative intelligence platform for legal teams, plus human services | AI meeting agent with live transcription, summaries, follow-ups and CRM sync |
| Who checks the words | Human-verified transcription and captions on offer | Automatic transcription and AI summaries |
| Live meetings | No live meeting notetaker shown on its site | Records Zoom, Google Meet and Teams in real time, capturing slides |
| Main audience | Prosecution, defence, law enforcement, civil law, court reporting, plus research, news and education | Sales, education and media |
| For developers | Speech-to-text API at rev.ai | Integrations and apps; no developer API headlined |
| Languages | Human captions in English and Spanish, subtitles in 17 languages | No language count listed |
| Getting started | No free plan stated | Free plan stated |
When accuracy has to stand up
This is where the human-verified service earns its place. If a transcript is going into a legal file, a court bundle or a published piece of journalism, a person checking every line is worth a lot more than speed. The vendor states its human accuracy and turnaround, and it offers court reporting and legal drafts on top.
The meeting notetaker doesn't pitch itself at that job. Its site describes automatic transcription and AI summaries, and there's no human transcription service shown. That's fine for remembering what was agreed on a sales call. It's not what you'd hand to a judge.
When the job is meeting notes
Flip the situation around and the picture changes. The notetaker records and transcribes Zoom, Google Meet and Microsoft Teams meetings as they happen, captures slides and writes a summary. It runs on desktop, iOS, Android and through a Chrome extension, and it can also transcribe audio and video files you upload.
Its site says Business and Enterprise accounts can auto transcribe files dropped into Dropbox, and it pushes summaries and follow-ups into your CRM. For sales teams, teachers and media people who spend the day on calls, that's the whole point. The legal-first platform doesn't show a live meeting notetaker at all, so it isn't really competing here.
Developers, captions and other languages
If you're a developer who wants to add speech-to-text to your own app, the legal-first company points you to rev.ai for an API. The notetaker's site talks about integrations and apps instead, and doesn't headline a developer API.
For captions, the human service offers captions in English and Spanish and subtitles in 17 languages. The notetaker doesn't list a language count on its site, so if you work in several languages, ask before you commit.
If neither is quite right
These four overlap with one side or the other. Our page on alternatives to Otter.ai for meeting notes has a longer list.

Frequently asked questions
Does Rev have an AI meeting notetaker like Otter?
Its site doesn't show a live meeting notetaker. It leads with a legal investigative platform and human transcription, captions and court reporting instead.
Does Otter offer human transcription?
Its site describes automatic transcription and AI summaries. There's no human transcription service shown, so for verified transcripts you'd need a different provider.
Which is better for legal work?
The legal-first platform is aimed squarely at prosecution, defence, law enforcement, civil law and court reporting, and sells human-verified transcripts. The notetaker isn't pitched at legal work.
Which one has a free plan?
The notetaker states a free plan. The other doesn't state one on its home page, so check its sign-up options.
Is there a speech-to-text API?
Developers are pointed to rev.ai for a speech-to-text API. The notetaker's site focuses on integrations and apps rather than a developer API.
