Otter vs Rev vs Descript vs Whisper: Prices and Free Limits (Sept 2026)

AI Transcription Tools Compared: Which One Fits How You Work — The AI Cheat Sheet

Short answer: Otter.ai for meetings and lectures (300 free minutes a month), Rev when accuracy can't be compromised, Descript if you're editing a podcast or video, and a Whisper app if the audio must never leave your computer. Whatever you pick, clean audio matters more than the tool.

How this comparison was built: I have not run the same audio file through all four of these tools, so this is not a head-to-head accuracy test — if that is what you came for, I would skip it. What it is: the current free-tier limits, prices and plan structures, read off each vendor’s own pricing page on the date below, next to the thing each tool is actually built to do. That is the part most comparisons get wrong, because they were written once and never re-checked.

Prices and limits above come from each vendor’s own pricing page, checked 22 September 2026: Otter, Rev, Descript. All three change them often, so check before you pay.

There are dozens of transcription apps out there, but a handful keep showing up because they work well enough for real people doing real work. Here are the ones most everyday users end up choosing between.

Otter.ai

Otter is probably the name you've heard most, and for good reason. It's built for meetings, interviews, and lectures, and it does a few useful things: it can join your Zoom, Google Meet, or Microsoft Teams call automatically, transcribe as people talk, and hand you a searchable transcript when the call ends. It also attempts to label who said what. If what you actually want is a bot that joins your Zoom or Teams call and writes the summary, see AI meeting note-takers instead.

Where Otter shines is clean, conversational English with a couple of speakers taking turns. Where it struggles is the same place most tools do — heavy crosstalk, thick background noise, or strong accents it wasn't trained heavily on. Its speaker labeling is helpful but far from perfect; expect to fix a few who-said-that mistakes by hand. Otter has a free tier with a monthly cap on transcription minutes, and paid plans that raise those limits and unlock extras. The free tier is usable for light work, which is rare.

Rev

Rev started life as a human transcription service, and that heritage matters. They still offer transcripts typed by real people, which remain the gold standard for accuracy — especially for messy audio, legal or medical content, or anything where a wrong word has consequences. Alongside that, Rev sells a faster, cheaper AI-only option. One thing worth knowing before you sign up: as of September 2026 Rev has pointed its subscription plans squarely at legal and investigative work — the pricing page is headed “Pricing Plans For Legal And Investigative Work,” and the paid seats run $25.49 to $47.99 per seat per month. If you just want a transcript now and then, the per-minute a-la-carte prices are the relevant ones, not the subscriptions.

The honest trade-off is right there in the two products. The AI version is quick and affordable but makes the usual machine mistakes. The human version costs more and takes longer, but a person can puzzle out a garbled phrase or an unfamiliar name in a way software still can't. If you're transcribing something high-stakes, Rev's human option is one of the few places to get near-flawless results without doing the work yourself.

Descript

Descript is a different animal. It's really a full audio and video editor, and transcription is the foundation it's built on. The trick that makes people fall in love with it: once your recording is transcribed, you edit the audio by editing the text. Delete a sentence in the transcript, and it disappears from the recording. For podcasters, video creators, and anyone who wants to clean up filler words and false starts, it's a different way of working. If your goal is purely to get a transcript and move on, Descript is more tool than you need. But if you're producing content, having the transcription and editing in one place saves real time.

Whisper (and the apps built on it)

Whisper is the open-source speech recognition model from OpenAI, and it quietly powers or inspires a lot of what you'll find elsewhere. On its own, running Whisper takes some technical comfort, so most non-technical people meet it through friendlier apps built on top of it — things like MacWhisper on a Mac, or various web services that use it under the hood. Whisper's strength is that it handles a wide range of languages and accents better than many older systems, and if you run it on your own computer, your audio never leaves your machine — a real privacy advantage. Its weakness is that, like all these tools, it can hallucinate words during silences or noise, confidently inventing text that was never spoken. Always skim the quiet stretches of a Whisper transcript.

The built-in options you already have

Don't overlook what's already on your devices. Apple's Voice Memos can transcribe recordings on newer iPhones, Google's Recorder app does the same on Pixel phones, and Microsoft Word has a built-in Transcribe feature for audio files. Google Docs has voice typing for dictation. These won't match the specialized tools for speaker labeling or long files, but for a quick voice memo or a short dictation, they're free, private, and right there.

A 17-second test with a free tool

Gemini transcribing a short synthetic voice memo about a bakery order — A synthetic voice memo about an invented bakery order, transcribed by Gemini (free). September 2026.

I made a 17-second clip with a text-to-speech voice, so the exact wording was known, and asked Gemini to transcribe it word for word with numbers as digits. It got the date, the 42 loaves, the $1,240 total, the name Priya and the 8:30 pickup right. It got one phrase wrong: “twelve of them sesame free” came back as “12 of them sesame 3”. One wrong word, and it is the one that matters most, because it turns an allergy note into nonsense. A clean voice with no background noise is a gentle test, so expect more slips like this on a real call, and check every number and allergy by ear before you rely on the text.

What actually affects accuracy

Here's the part the tool comparisons often skip: the biggest factor in transcription quality usually isn't the tool. It's the audio.

Recording quality does most of the heavy lifting. A clean recording with a decent microphone close to the speaker will beat a distant phone in a noisy cafe every time, no matter which app processes it. If you have any control over the recording, that's where to spend your effort. Get the mic close. Reduce background noise. Ask people not to talk over each other.

One speaker at a time is easy; a crowd is hard. Every tool handles a single clear voice reasonably well. The moment two people overlap, accuracy drops and speaker labels get scrambled. Roundtable discussions and lively group interviews are the hardest case.

Accents and specialized vocabulary trip things up. These models were trained mostly on common, widely-recorded speech. A strong regional accent, a non-native speaker, or a conversation full of industry jargon, medical terms, or unusual names will produce more errors. Some tools let you add a custom vocabulary or glossary, which helps with recurring names and terms.

Language matters. Most of these tools are strongest in English. Support for other languages varies a lot, and mixing two languages in one recording is especially challenging.

Four things that go wrong

Don't trust a transcript you haven't skimmed. AI transcription errors aren't random typos — they're plausible-sounding wrong words. The tool might swap a name, flip a can't to a can, or invent a sentence during a pause. For anything that matters, read the transcript against the audio at least once. The time you save is still enormous; it's just not zero effort.

Get consent before you record. This isn't just polite — in many places it's the law. Some regions require every person in a conversation to consent to being recorded; others require only one party. If you're recording interviews, calls, or meetings, know the rules where you and the other people are, and when in doubt, ask and get a clear yes. A tool that auto-joins your video calls makes this easier to forget, so build the habit of announcing it.

Think hard about sensitive audio. When you upload a recording to a cloud service, you're handing your audio to a company's servers. For a public lecture, who cares. For a therapy session, a confidential business call, a medical conversation, or an interview where you promised anonymity, that's a real consideration. Read the tool's privacy policy: does it use your recordings to train its models? How long does it keep them? Can you delete them? Apply the same three-bucket test I use for documents. For the most sensitive material, a tool that runs entirely on your own computer — like a local Whisper app — keeps the audio off the internet entirely.

Watch the free-tier limits. Free plans usually cap your monthly minutes, restrict file length, or hold back features like speaker labels and exports. That's fine to start, but check the limits before you commit to a tool for a big project, so you're not stuck halfway through with a paywall.

Which one fits which job

There's no single winner, because the right tool depends on what you're transcribing. If you're capturing meetings, interviews, and lectures and want something easy that handles live calls, Otter.ai is the natural starting point, and its free tier lets you test it at no cost. If accuracy truly can't be compromised — legal, medical, or high-stakes material — Rev's human transcription is worth the money and the wait. If you're producing podcasts or video, Descript's edit-by-text approach is in a class of its own. And if privacy is your top concern, a Whisper-based app running on your own machine keeps everything local.

Whatever you choose, the two habits that matter most are the same across every tool: record the cleanest audio you can, and always skim the result before you rely on it. Do those two things, and even an imperfect tool will save you hours. Skip them, and the fanciest app in the world will still let you down.
