Cassette vs Otter

Both turn a conversation into a transcript and notes. The difference is where that happens: Cassette writes them without an outside AI service and, once your language has downloaded, works in airplane mode, while Otter transcribes in its cloud and can join your online meetings for you.

The short answer

Pick Cassette if

You record in the room: lectures, interviews, meetings around a table.
You want your tapes kept on your phone, with no outside AI service.
You are often offline, on a plane or in a basement lecture hall.
You would rather pay once than subscribe.
On a Mac, you don't want anything joining the call.

Pick Otter if

Your team wants a shared workspace, channels and comments.
You want a notetaker that joins Zoom, Teams or Google Meet on its own.
You need Salesforce, HubSpot or Zapier, or a web app and Windows.
Your meetings are mostly online and you are always connected.

Side by side

	Cassette	Otter
Where the transcript is written	On your phone. Android always; iPhone on the device for the languages it supports there, otherwise by Apple's speech recognition.	On Otter's servers. Offline, Otter keeps recording and processes the tape once it can upload it. [1]
Works in airplane mode	Yes: recording, the transcript and the notes, once the language and the notes model have downloaded.	Recording only. The live transcript pauses until a connection is back. [1]
Who writes the notes	Apple's models on iPhone and Mac (simpler notes, written on the device, where Apple Intelligence is missing), Cassette's own model on Android phones with 8 GB of memory or more (other Android phones get a few clear lines from the tape). Never an outside AI service.	Otter's AI: summaries with action items and outlines, plus AI Chat. [2]
Online meetings	On the Mac, Cassette records what the Mac plays and your microphone. Nothing joins the call.	Otter's notetaker joins Zoom, Microsoft Teams and Google Meet to write and share notes. [2]
Free plan	Unlimited recording. Transcripts and notes for tapes under 3 minutes and for 2 longer tapes a month.	300 transcription minutes a month, up to 30 minutes per conversation, the 25 most recent kept. [2]
Paid plan	Recording is free and unlimited, with no minute meter. Premium is $1.99 a week, $5.99 a month, or $49.99 a year with a 7-day free trial, or pay once with Lifetime. One purchase covers iPhone, iPad and Mac.	Pro is $16.99 a month, or $8.33 a month billed annually: 1,200 minutes a month, up to 90 minutes per conversation. [2]
Pay once	Yes, Lifetime.	No one-time plan listed. [2]
Devices	iPhone, iPad, Mac, Apple Watch and Android.	Web, iPhone, Android, Mac and Windows apps, and a Chrome extension. [2]
Languages	Your iPhone's language, wherever Apple's speech recognition supports it; many languages on Android.	English, Spanish, French, German, Japanese and Chinese. [2]

Before you record
