Is Inumaki really free?

Yes — Inumaki is 100% free and open source under the MIT license. There's no subscription, no word cap, no trial, and no paid tier. Download it, run it, and dictate as much as you want, forever.

Does my voice or audio ever get uploaded?

No. Transcription runs entirely on your own computer using whisper.cpp, with the model bundled inside the app. Inumaki makes no network calls to transcribe your speech — your audio is processed on-device and never leaves your machine. Because it is open source, you can read the code and verify this yourself.

Does Inumaki work offline, without internet?

Yes. Everything happens locally on your CPU, so Inumaki works fully offline — on a plane, on bad Wi-Fi, or in air-gapped and secure environments where cloud dictation tools are blocked. The only time it touches the internet is when you check for a new version.

How do I use it / what's the hotkey?

Press Ctrl + Shift + Space anywhere in Windows to start listening, speak naturally, and your clean transcript is ready to paste at your cursor in any app — editors, chat, browsers, terminals.

How accurate is the transcription?

Inumaki uses the whisper.cpp ggml-base.en model, which produces punctuated, well-formatted English text and handles natural speech well in a reasonably quiet room. It runs after you finish speaking (in seconds), rather than streaming word-by-word.

Does it support languages other than English?

Not yet — Inumaki ships with the English whisper.cpp model (ggml-base.en) today. More languages are on the roadmap, and because it is open source, you are free to drop in a different whisper.cpp model now. If you need 100+ languages right away, a cloud tool like Wispr Flow may suit you better; Inumaki focuses on excellent, private, free English dictation.

Windows shows a SmartScreen warning when I run it — is that safe?

Yes. Inumaki is an open-source indie app and the installer isn't code-signed yet, so Windows SmartScreen shows a 'Windows protected your PC' prompt for unrecognized publishers. Click 'More info', then 'Run anyway'. If you'd rather not trust a binary at all, you can build it yourself from the public source on GitHub.

What are the system requirements?

Windows 10 or 11, 64-bit (x64). Any modern CPU works — no GPU and no internet are required. You'll need a microphone. There's no account to create. Windows on ARM isn't supported yet.

Is there a Mac or Linux version?

Not yet — Inumaki is Windows-first. macOS and Linux are not supported at this time. It is open source, so cross-platform contributions are welcome, but the current build targets Windows x64 only.

How is Inumaki different from Wispr Flow?

Wispr Flow is a polished, paid, cloud-based tool with AI auto-editing and 100+ languages. Inumaki is the free, open-source, fully-local alternative: your audio never leaves your PC, there is no account or subscription, and you can audit every line of code. The trade-off is that Inumaki is English-only and Windows-only today, and does not yet do AI rewriting. If privacy, price, and offline use matter most, Inumaki is for you.

How do I uninstall it?

Inumaki uninstalls like any standard Windows app — through Settings → Apps → Installed apps, or "Add or remove programs". Because nothing is stored in the cloud and no account exists, removing the app removes everything; there is no data left on a server.

Why is it called Inumaki?

It's a nod to a character known for speaking in a very deliberate, controlled way — fitting for a tool that turns your spoken words into precise text. It's published by Camie Tech.
