TranscriptionSuite
Free, open-source speech-to-text that runs entirely on your own machine, with diarization, summaries, and a calendar-based audio notebook.
Pick TranscriptionSuite if total local control and zero per-minute cost matter more than convenience. Longform and live transcription, speaker diarization, AI summaries, and the calendar-based Audio Notebook all run on your machine, across Whisper, NeMo Parakeet & Canary, SenseVoice, VibeVoice-ASR, whisper.cpp, and MLX. Compared to Otter.ai or Rev, you get privacy and no per-minute billing, but you pay in setup: roughly 30 minutes of model downloads, Docker or Tailscale configuration, and no mobile app or cloud collaboration. It's a strong open-source alternative for solo journalists, researchers, and developers who want an OpenAI-compatible STT API with their own GPU.

Skip TranscriptionSuite if you need a zero-config tool your whole team can log into from a phone or browser - it asks for roughly 30 minutes of model downloads and some Docker or Tailscale setup before first use.
AI summaries and Assistant chat require an OpenAI-compatible provider that you configure and, if you point it at a cloud option like Groq or OpenRouter, pay for separately.
TranscriptionSuite is free under GPLv3+, so it undercuts per-minute cloud services like Otter.ai and Rev entirely - your only recurring cost is the AI provider you optionally wire in and the hardware you run it on. It fits individuals, journalists, and researchers with a reasonably capable GPU (a documented benchmark is 30 minutes of audio in under a minute on an RTX 3060). Teams that need shared workspaces, admin controls, or an SLA should budget for a paid cloud alternative instead.

About TranscriptionSuite
TranscriptionSuite is a free, GPLv3+ speech-to-text application that runs entirely on your hardware. It handles both longform recording (mic or system audio, with a rolling preview while you speak) and Live Mode for real-time, sentence-by-sentence dictation, and it labels every voice in a recording with automatic speaker diarization. It is model-agnostic: you pick from Whisper, NVIDIA NeMo Parakeet & Canary, SenseVoice, VibeVoice-ASR, whisper.cpp, or MLX depending on your machine, and the app manages the engine - Docker on Linux and Windows, native Metal on Apple Silicon - with guided setup checks and one-click image updates. Performance is documented at 30 minutes of audio in under a minute on an RTX 3060. Recordings land in the Audio Notebook, a calendar view where you browse by month, scrub through your day hour by hour, replay the original audio, and find spoken phrases with full-text search. You can generate an AI summary of any note or chat about it with the AI Assistant, which connects to any OpenAI-compatible provider - local LM Studio or Ollama, or cloud options like Groq and OpenRouter. Translation from 90+ languages to English is built in. It suits privacy-conscious journalists, researchers, and professionals handling confidential recordings who don't mind downloading models (around 30 minutes before first use) and doing some setup. It is a self-described hobby project by an engineer who is not a software engineer, dogfooded daily, with support community-driven via GitHub.
Behind the Verdict
TranscriptionSuite's core pitch is unusually clean: nothing leaves your machine. Every feature on the site reinforces that - recording from mic or system audio, Live Mode dictation, diarization, summaries, and the Audio Notebook all run locally, and the AI Assistant can be pointed at local LM Studio or Ollama instead of a cloud provider. The breadth of engine support is the standout engineering decision. Whisper, NVIDIA NeMo Parakeet & Canary, SenseVoice, VibeVoice-ASR, whisper.cpp, and MLX are all selectable, so you can match the model to your hardware rather than the other way around, and the app handles GPU acceleration across CUDA, AMD, Intel, and Apple Silicon Metal. The documented benchmark - 30 minutes of audio in under a minute on an RTX 3060 - is the kind of concrete number most transcription vendors avoid. Where it struggles is everything that isn't transcription. The AI Assistant and summaries require a separately configured OpenAI-compatible provider, so "AI features" is really "bring your own model endpoint." Translation is one-way only, from 90+ languages into English, so non-English output workflows won't work here. The Remote access story is Tailscale or LAN rather than a hosted web app, which means reaching your home GPU from elsewhere depends on you running that tunnel. And the project is refreshingly candid about its own pedigree: the author calls it a hobby project, describes the code as "vibecoded," and notes he is an engineer but not a software engineer, learning Python, git, uv, and Docker as he goes. That transparency is a virtue, but it also sets expectations - support is community-driven through GitHub, not a help desk with SLAs. The honest read: if your problem is "I have sensitive or very long audio and I refuse to upload it," this is one of the more complete open-source answers available, and it costs nothing but your setup time. If your problem is "I want a meeting recorder my whole team logs into from their phones," this is the wrong tool and you should look at Otter.ai or a similar cloud service. Treat the Audio Notebook as the sleeper feature - a calendar for your voice, with full-text search and original-audio playback, is a genuinely different way to revisit recordings than a folder of transcript files.

Real-world workflow fit
Concrete scenarios for the personas TranscriptionSuite actually fits — and what changes day-one when you adopt it.
Records a long interview from the microphone, lets the rolling preview run, then gets the full transcript seconds after stopping with speaker diarization labeling each voice.
Outcome: A speaker-labeled transcript stays on their machine, replayable from the Audio Notebook calendar with full-text search if a quote needs checking.
Imports recorded audio files and runs translation from 90+ languages to English alongside the local transcription engine that fits their GPU.
Outcome: English transcripts are available without sending sensitive source recordings to a cloud service, with .txt and .srt exports for later analysis.
Points the OpenAI-compatible API at TranscriptionSuite as a drop-in STT endpoint and sets an outgoing webhook to push finished transcripts into their own pipeline.
Outcome: Existing tools that already speak the OpenAI API get local transcription with no per-minute billing and no data leaving the network.
Use Cases
- Transcribe hours of interview recordings locally with speaker labels.
- Take live dictation notes in a meeting with real-time sentence output.
- Search past audio notes by full-text and replay the original audio from the calendar.
- Chat with a local AI about your transcription notes via LM Studio.
- Access your home GPU for transcription from anywhere using Tailscale.
- Import video or audio files and export .txt, .srt, or .ass transcripts.
Models Under the Hood
as of 2026-10-15
Limitations
- The AI Assistant and AI summaries rely on an OpenAI-compatible provider (local LM Studio or Ollama, or cloud providers like Groq and OpenRouter) that you must configure separately, and the transcription engines themselves depend on your own GPU or Apple Silicon hardware, with setup managed via Docker on Linux/Windows or native Metal on Apple Silicon.
- Translation is one-way only, from 90+ languages to English.
- Remote access is via Tailscale or LAN rather than a hosted web app, so reaching your machine from elsewhere depends on you maintaining that connection.
- The project is self-described as a hobby project, with the author describing the code as vibecoded and noting he is an engineer but not a software engineer.

Where the pricing makes sense
The company stage and team size where TranscriptionSuite's pricing actually pencils out — and where peers do it cheaper.
TranscriptionSuite is free under GPLv3+, so it undercuts per-minute cloud services like Otter.ai and Rev entirely - your only recurring cost is the AI provider you optionally wire in and the hardware you run it on. It fits individuals, journalists, and researchers with a reasonably capable GPU (a documented benchmark is 30 minutes of audio in under a minute on an RTX 3060). Teams that need shared workspaces, admin controls, or an SLA should budget for a paid cloud alternative instead.
Setup time & first value
How long it actually takes to get something useful out of TranscriptionSuite — broken out by persona, not the marketing-page minute.
For a developer or technical user on a GPU box: expect around 30 minutes of model downloads plus Docker or native Metal setup before the first transcript - the app provides guided setup checks and one-click image updates to smooth this. On Apple Silicon, native Metal install is the quicker path. Non-technical users who avoid Docker and Tailscale should plan for considerably longer, and there is
Switching to or from TranscriptionSuite
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Otter.ai: Export your recordings or transcripts, then import the audio files into TranscriptionSuite and re-run transcription locally with diarization.
- →From Rev: Download your source audio, import it for local transcription, and use the .srt/.txt exports to replace Rev's transcript files.
- →From a plain Whisper or whisper.cpp script: Point your existing pipeline at TranscriptionSuite's OpenAI-compatible API instead of calling the model directly.
- →From RealtimeSTT: TranscriptionSuite was inspired by RealtimeSTT, so live-dictation workflows map over to Live Mode with minimal changes.
- ↗To Otter.ai: Export your transcripts as .txt, then upload the original audio to Otter.ai if you need cloud collaboration and shared workspaces.
- ↗To Rev: Export .srt from TranscriptionSuite and hand the source audio to Rev if you need human-reviewed transcripts.
- ↗To a cloud STT API: Swap the OpenAI-compatible endpoint you configured for a hosted provider and keep your downstream pipeline unchanged.
- ↗To another local Whisper setup: Export transcripts and model notes, since your engine choices (Whisper, whisper.cpp, MLX) carry over to other local stacks.
