Why CTRL

Not yet another local AI client.

Three things make it different — and none of them is "we host a model for you".

Ambient, not an app you open

One global hotkey, one morphing conversation — no tab-soup. Capabilities live in an open registry (MCP / CLI / Skills), so the surface stays simple while the ecosystem scales.

Bring your own everything

Your keys, your models, your brain. No account, no markup, no default model spend. Keys live in your OS keychain — we literally can't read them.

Plain-text all the way down

Notes, tools, skills, memory — all markdown you can open in vim in 100 years. There's no "export", because nothing was ever imported.

How it works

One keystroke to a finished thing.

No wizard, no setup tour. Summon it, ask once, keep what comes out.

1

Press Ctrl

Summon an ephemeral workspace from anywhere — over any app you're in.

2

Ask once

One assistant reads your intent and routes it to the right tool — shown, never hidden.

3

Watch it morph

The surface becomes the output: a doc, a table, an editable page, code.

4

Keep it

Copy, export as a file, or save into a local vault you fully own.

Build once, share the recipe.

Package a tool as a plain-text definition and publish it to the commons — one-click install what others share. Only definitions travel; your data and keys never leave your machine. CTRL sells the substrate, the commons stays free.

ShareA tool = a git-diffable manifest. No data, no keys.
Be sharedInstall someone's definition; it runs on your own data.
Own itUninstall CTRL and every file stays on your disk.

Your company. Your keys. Your machine.

Download CTRL and press Ctrl — your AI workspace is one keystroke away.
