Sotto - Meeting Recorder

Sotto records your meetings and lectures, writes them down, works out who said what, and summarises the result — entirely on your iPhone.

No account. No server. Nothing uploaded. You can check that claim in ten seconds: turn on Airplane Mode and record something. Everything still works.

PRIVATE BY ARCHITECTURE, NOT BY POLICY

Most meeting apps upload your audio and promise to behave. Sotto is built so there is nothing to misbehave with. Your recordings never leave the device, so there is no server to breach, no retention schedule to trust, and no policy that can quietly change next year.

That is also why a lot of people can use Sotto when they can't use anything else — if your employer, your regulator or your clients have ruled out cloud transcription, this is a different conversation.

UNLIMITED, AND FREE

Recording runs on hardware you already own, so extra minutes cost nothing to provide — and charging for them would be an invented limit. Free, permanently, with no minute caps:

• Unlimited recording
• Unlimited transcription, in around 40 languages
• Speaker labels on every recording
• Every export format
• 10 AI summaries a month
• No account, ever

WHO SAID WHAT

Sotto separates the voices in a recording and labels each speaker — the thing Voice Memos and Notes don't do. It runs on the Neural Engine, on the device.

This is measured rather than asserted. Against the AMI Meeting Corpus and its human annotation, Sotto found all four speakers in all four test meetings, with a 9.7% error rate on close-talk audio and 16–24% on a single microphone across a table. Two of those meetings were held out entirely while tuning.

When the models aren't available, Sotto shows you where the speaker changes but doesn't attach names. A confident wrong attribution is worse than none.

SUMMARIES THAT POINT BACK AT THE AUDIO

An abstract, the key points, and the action items — written by Apple's on-device foundation models. Every action item links to the moment it came from, so anything that matters is two seconds from being checked.

YOUR DATA LEAVES HOW YOU WANT

Export as plain text, Markdown, SRT, WebVTT, JSON, or the original audio file. All formats free. No lock-in, no subscription required to get your own words out.

WHAT SOTTO CAN'T DO

• It can't record phone calls, FaceTime or Zoom. iOS gives no app access to call or system audio. Sotto records the room.
• Summaries need Apple Intelligence, so they require iPhone 15 Pro or newer. Recording, transcription and speaker labels work without it.
• Summaries can be wrong. A small on-device model is still a model — that's why every claim links back to the audio.

SOTTO PRO

There's no server bill to pass on here, because there's no server. Pro is how an app with no ads, no tracking and no data business stays alive. It lifts the summary limit and unlocks custom vocabulary for names, jargon, drug names and case law.

Available monthly, yearly, or as a one-time lifetime purchase.

REQUIREMENTS

iOS 26 or later. iPhone 15 Pro or newer for AI summaries. Speaker labelling downloads its models once, then works offline.

Sotto is a recorder, not a legal adviser. Recording other people is regulated in many places, and complying with the rules that apply to you is your responsibility.
