Is Whisper on-device like Blabb?

Yes — Whisper's models run on your own machine, so neither tool sends your audio to a cloud. The difference is shape: Whisper is a speech-recognition model and library that transcribes audio files, while Blabb is a finished dictation app that types cleaned text into your Windows apps as you speak.

Can Whisper dictate into my apps the way Blabb does?

Not out of the box. Whisper transcribes audio files; to get live text into Word, Outlook, or a browser, you'd build that layer yourself (voice activity detection, hotkey, text injection, cleanup). Blabb ships all of that — press F9, talk, and the cleaned text lands at your cursor.

Is Whisper really free?

Yes — Whisper is free and open source under the MIT licence. The cost is setup: you install Python, PyTorch, and ffmpeg, download model weights, and a CUDA GPU is recommended for good speed. Blabb is USD $4.99/month (USD $49.99/year, or $99 once) with a 2,000-words-a-day free tier, and ships its models in the download so there's nothing to configure.

Blabb vs Whisper
Two on-device tools

OpenAI's Whisper is the free, open-source speech-recognition model that a lot of modern dictation is built on top of — and like Blabb, it runs on your own machine. So this isn't on-device versus cloud; it's the model versus the finished tool. Whisper transcribes audio files; Blabb is dictation that types into your apps. As of July 2026 — Whisper is open source; check its GitHub repo for the current state.

01The honest read

Both local. Model versus product.

Choose Whisper if…

You're a developer or tinkerer who wants the raw model — to transcribe files, fine-tune, or build your own tool — and you're comfortable installing Python, PyTorch, and ffmpeg and wiring up a GPU. For research and custom pipelines, Whisper is the foundation.

Choose Blabb if…

You want to talk and have clean text appear in Word, an email, or a ticket — without setting up a Python environment or building a front end. Blabb adds the parts Whisper doesn't ship with: live dictation into apps, voice activity detection, AI cleanup, and a one-key workflow.

On price and privacy

Both keep your audio on the machine, so there's no cloud privacy difference. Whisper is free and open source; Blabb is USD $4.99/month (or $99 once) for the finished product — the parts that turn a transcription model into dictation you can actually use day to day. Free model versus supported product — pick the job you actually have.
