Fluid intelligence,
free and private

What is 0switch?

0switch is one private surface for AI on your own computer, in every app. Dictation is the first utility, not the point: the same surface covers composing, agent mode, meetings and vision, so you own unlimited AI instead of renting it. Hold one hotkey, speak, and your words are typed wherever the cursor blinks: native apps, web apps and the terminal alike, in 60+ languages auto-detected mid-sentence. It runs locally and offline by default: speech-to-text, AI cleanup and a local assistant all stay on your machine, with nothing sent to a server unless you choose a cloud model. Available on macOS, with Windows and Linux in closed beta.

Pricing

Free is the product, not a trial: the core local features are free forever, with no account, no credit card and no internet required, and bring-your-own-key (BYOK) is free on every tier. Pro is a $49 one-time perpetual license that unlocks all local features, unlimited, on every machine you own, and never expires. Plus is an optional cloud add-on at $9.90 per month (or $99 per year) that adds 10,000 monthly cloud credits and frontier models with zero setup, for machines that can't run the larger local models. Pro and Plus stack: cancel Plus and you fall back to Pro, not to Free.
