"yeah I was using Otter for a while but then I realized all my meeting recordings and notes are just sitting on their servers and I have no idea who can see them and some of these conversations are really confidential so I need something that doesn't send anything anywhere"
After reviewing the data handling practices of Otter.ai, it became clear that all recorded meetings and transcriptions are stored on remote servers with uncertain access controls. Given the confidential nature of the conversations involved, a fully local transcription solution is necessary.

This is the simplest way to 10X your productivity.
I can finally talk to Claude Code with only two keys.
My favorite thing about Mumbl is its simplicity. There aren't any loops you have to go through to make it work and it's intertwined with my device really well. Right now I mainly use Mumbl for school work!
I was unsure on how I would feel talking to my computer, but I figured I'd give it a try. Turned out 10x better than I had expected. It's crazy how much time has already saved me!

We dropped Otter the week the lawsuit hit. Mumbl gave our team the same voice-to-text speed boost without any cloud dependency. No bots joining calls, no recap emails leaking info, no audio on anyone else's servers.
I was an Otter Pro subscriber for two years. Switched to Mumbl and realized I was paying for features I never used. All I needed was to talk and get clean text. Mumbl does that better, cheaper, and without the privacy risk.
Our compliance team spent three months reviewing Otter's data practices and couldn't get comfortable. They approved Mumbl in one meeting because there's no third-party data handling to review. Everything stays on the device.

Why professionals are leaving Otter.ai
"They retain your data in a cloud service and use your recordings as future training data."
Otter's class-action lawsuit revealed it auto-joins meetings without participant consent.
A VC firm had hours of confidential information exposed through Otter recap emails.
Mumbl doesn't have servers to send your audio to, even if we wanted to. Everything is local.

Frequently asked questions
What happened with Otter.ai?
In August 2025, Otter was hit with a class-action lawsuit for "deceptively and surreptitiously" recording private conversations to train AI without consent. The lawsuit revealed auto-joining meetings without participant consent and retaining recordings for AI training.
Does Mumbl work for meetings?
Mumbl is designed for voice-to-text — hit a hotkey, speak, get formatted text. It doesn't auto-join or record meetings. Your audio stays on your device and is processed instantly.
Is the free tier actually usable?
Yes. 10 transcriptions per week, forever, no credit card required. Otter gutted their free tier — Mumbl's stays generous because local processing doesn't cost us server fees.
