Transcribe
Transcribe, translate,
summarize — locally.
Kajo Voice transcribes interviews, lectures, meetings, and field recordings on your Mac, Windows, or Linux machine — your audio never uploads.
Replace the stack. Pay once.
Most people pay a cloud transcriber for the recordings they already have, then a cloud notebook to keep and query them — every month, forever — and still cannot keep any of it private. Kajo bundles transcription, a searchable library, and cited chat for a single $49 payment — on Mac, Windows, and Linux, with nothing leaving your machine.
| Tool | Listed /mo |
|---|---|
| TurboScribe Unlimited — cloud file transcription, billed monthly | $20.00 |
| Otter.ai Pro — cloud meeting notebook with AI chat, billed monthly | $16.99 |
| Typical stack total, every month | ~$36.99 |
| Kajo (transcribe + library + chat) | $49 once |
List prices read from each vendor's pricing page on 2026-09-09. Your stack may differ — the point is that a recurring cloud stack bills every month, while Kajo is a single $49 payment that unlocks unlimited imports and Lifetime convenience (watch folders, batch export), on-device. At ~$36.99/mo, the stack passes Kajo's one-time price in about 2 months — then keeps charging.
What you get
Any file, any source
Audio and video files — MP3, WAV, M4A, MP4 and other common containers — plus whole folders. Lifetime adds watch folders. Everything is decoded and transcribed on your machine.
On-device transcription
Whisper large-v3 turbo — 98 languages, on-device via whisper.cpp.
Speakers, labelled automatically
After transcription Kajo detects who spoke when, on-device. Rename the roster, reassign a turn, or restore the automatic labels — every summary, chat answer, and export uses the names.
Translate + summarize locally
One on-device Gemma 4 model translates the transcript and writes summaries — entirely on-device, with no cloud round-trip.
Export every format
TXT, Markdown, DOCX, SRT, VTT, JSON, CSV, PDF, and QDPX for editors, captions, and CAQDAS tools.
Three reasons Kajo exists
-
Local-first / private by default
Your audio never leaves your laptop.
Audio is transcribed on-device — there is no cloud-processing path. Private by architecture.
-
Cross-platform, including Linux
Mac, Windows, and Linux — one product, three operating systems.
Native installers for all three. Linux is a first-class target, not a port — the only local audio knowledge base that takes it seriously.
-
Cited chat
Ask questions across your archive — get cited answers.
Chat with your entire library using a local model. Every answer links back to the exact moment in the recording — no copy/paste.
Frequently asked questions
Does Kajo upload my audio to transcribe?
No. Transcription runs on-device. Translation, summaries, and chat run on-device too — Kajo never uploads your audio or transcript text.
Is there a per-minute fee?
No. You pay once and your machine does the compute. Free covers 5 files or 150 minutes of audio — total, for life. A single $49 purchase removes the caps; your installed version keeps working forever.
How does Kajo compare to MacWhisper or Superwhisper?
Great local transcription — then it is just a text file. Kajo turns every transcription into a searchable, chat-able archive you query in-app with cited answers, on Mac, Windows, and Linux.
