Transcribe · Summarize · Zero Upload
Your Private AI Scribe
Record both sides of any meeting. Transcribe and summarize locally on your Mac. No cloud, no data ever leaving your machine.
Free to try · No account required · Requires macOS Tahoe on Apple Silicon
Filmed with WiFi off. Transcription and local AI summary run entirely on-device.
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Unpublished research, trade secrets, NDA-protected discussions, privileged conversations.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.
Capture Every Meeting
Mic, system audio, or both. No virtual drivers, no bots. Just hit record.
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.
Who Said What
An on-device engine detects individual speakers and color-codes your transcript automatically. Works offline, no cloud involved.
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.
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.
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 1Channel 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 beyondNo 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.

I show my work.
Real benchmarks, honest findings, and the things that surprised me along the way.

Thoth for ADHD and autism: what I learned
A user told me she is autistic and has ADHD, and that Thoth helps her process information. I had not thought of Thoth as an accessibility tool. I should have.

Parakeet translates French audio
I added Parakeet expecting fast transcription. On non-English audio, it was doing something stranger: involuntary simultaneous translation.

Your meeting audio belongs on your Mac
Cloud meeting recorders upload your audio to US servers, creating legal exposure for everyone on your calls. Here is what that means in practice.
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.
