The Scribe's Oath

Three reasons. One decision.

On-device means your data never leaves, your attention stays on the conversation, and what was said is always readable.

Your data stays yours

Unpublished research, trade secrets, NDA-protected discussions, privileged conversations. If it would matter in the wrong hands, it should never leave your machine. Thoth keeps everything on your hardware. Always. And because Thoth has no app server and no user database, there is nothing to breach, sell, or subpoena in the first place.

Be present, not busy

When you know every word is captured, you stop taking notes and start listening. Focus on the conversation. Thoth handles the record.

Read instead of re-listen

For ADHD, autism, hearing impairment, and auditory processing differences, a searchable transcript is not a convenience. It is access. Read, skim, and Cmd-F your way through any recording, at your own pace, on your own terms. Who uses Thoth for accessibility →

The Scribe's Craft

Every tool a scribe needs.

Recording, transcription, speaker detection, and AI summaries. All running on your Mac.

Recording

Capture Every Meeting

Mic, system audio, or both. No virtual drivers, no bots. Just hit record.

Live Transcript

Words in Real Time

A floating panel shows your transcript as you speak. Two models run in parallel: a fast one for instant preview, a quality one for the final text. All on-device, zero latency to the cloud.

Speaker Detection

Who Said What

An on-device engine detects individual speakers and color-codes your transcript automatically. Works offline, no cloud involved.

AI Summary

From Meeting to Insight

Notes, action items, key decisions: extracted and formatted in one click. Choose between five on-device models or your own cloud API key.

On-Device AI

No Cloud Needed

Choose from five local models, from the nimble Ministral 3B to the powerful Gemma 3 12B. No API key, no cloud. Your transcript never leaves your Mac.

AI Assistant

Ask Your Recording

Chat with any recording. Ask questions, get answers grounded in the transcript. Works with local models and your own API key.

Built for Mac

A real Mac app.

Native SwiftUI, proper Dark Mode, and a menu bar mode. No Electron, no web wrapper.

Native SwiftUI

Real macOS app. Collapsible sidebars, smooth animations, proper Dark Mode. Runs on AppKit, not Electron.

Export & Share

PDF, Word, Markdown, RTF, or JSON with timestamps and color-coded speakers. Or share any transcript or summary directly to Mail, Messages, and AirDrop in one tap.

99 Languages

Auto-detects the language and transcribes it. English, French, Japanese, Arabic: Whisper handles them all, entirely on your Mac.

Audio Architecture

Two channels.
Zero ambiguity.

Most tools blend your mic and remote audio into a single stream, then guess who spoke when. Thoth keeps them separate from the very first sample. No guesswork needed.

Channel 1 · Mic

Your Voice

Dedicated stream from your microphone. Captured independently and identified as you before transcription starts. Never mixed with remote audio.

Always Speaker 1

Channel 2 · System

Remote Voices

Captured from Zoom, Teams, Meet or any app via the macOS audio engine. A completely independent stream. No screen capture, no bot joining the call.

Speaker 2 and beyond

No guesswork. Every word attributed correctly.

When channels are separate, speaker attribution for remote participants is deterministic, not estimated. Mic is always you. System audio is always them. Even when everyone talks at once.

Absolute Privacy

Under the Scribe's Seal.

Your data stays yours. Built from day one for people who handle confidential information.

100% Offline Engine

Transcription runs on your Mac through WhisperKit and CoreML. No audio ever leaves your machine.

Local Speaker Detection

An on-device engine detects who is speaking and color-codes your transcript. No cloud processing involved.

On-Device AI Summaries

Choose from five local models (1.9 GB to 6.8 GB) and run AI summaries entirely on your Mac. No API key, no cloud.

Bring Your Own Key

Prefer OpenAI, Anthropic, or Google? Use your own API keys. Requests go direct from your Mac to the provider.*

Keychain Secured

API credentials stay locked in your Apple Keychain. Thoth never stores keys in plaintext or sends them anywhere.

No App Server

Our server hosts this website. That is all it does. No user database, no license server, no record of who you are. Purchases go through Apple directly.

FAQ

Common questions.

Does Thoth record both sides of a Zoom or Teams meeting?
Yes. Thoth captures your microphone on one channel and the meeting app's system audio on a separate channel, so every participant is recorded without joining a bot to your call.
Is Thoth free to use?
Thoth is free to try with full transcription, up to 30 minutes per mic recording and 15 minutes for mixed or system audio. Pro unlocks unlimited duration, system audio recording, and unlimited AI enhancements.
Does my audio get sent to the cloud?
No. Transcription runs entirely on your Mac using WhisperKit and CoreML. Your audio never leaves your device. If you use a cloud AI key for summaries, only the text transcript is sent directly from your Mac to your chosen provider.
Does Thoth work offline?
Yes. Recording and transcription work with no internet connection. On-device AI summaries also work offline. An internet connection is only needed if you choose to use a cloud AI key.
What Mac models does Thoth support?
Thoth requires macOS Tahoe (macOS 26) on Apple Silicon. macOS Tahoe does not run on Intel Macs.
What does Thoth know about me?
Nothing. Thoth has no app server and no user database. There is no Thoth account. Purchases and activations go through Apple directly, so we never see your name, email address, device, or payment details. Our server hosts this website. That is all it does.
