How OIOXO works
Your AI coder.
On your device.
A chat-first IDE where the model runs on your machine and edits a real folder, with every change reviewable and undoable. Free to start.
What it does
Describe a change. Review what landed.
Open a real folder — on disk, in the browser, imported from a zip or cloned from Git. Say what you want. The model edits the folder and asks before every write.
The Changes panel lists each edit with Keep and Undo, and every agent run is a checkpoint you can revert. Nothing is all-or-nothing.
Changes and checkpointsWhy it’s different
The model runs on your device.
OIOXO Light, Prime and Ultra, or an open model, download once and run in your browser — on the CPU, on the GPU with WebGPU, or on the desktop’s native engine.
Your code, your prompts and the model stay on the machine. Our servers see token counts for the free allowance and a few usage beacons you can switch off — never what you wrote.
What stays on your deviceWhy it’s different
Your key is a choice, never the default.
On device · Auto · Your key. Add an Anthropic key or any OpenAI-compatible endpoint when a task needs a bigger model.
The row shows the price per million tokens and the chat header shows the running cost. Auto offers your key when a run fails — it offers, never switches silently, never re-sends.
The three modesWhy it’s different
It says honestly whether the page runs.
A written page is parsed, checked for a script that promises what the markup cannot deliver, then loaded in Preview and read back.
The receipt separates “parsed clean, not run” from “checked by running it”. Small models build simple pages well and larger apps poorly, and the receipt says which happened.
Preview and the checksAnywhere
Web first. Desktop for speed. Phone as a companion.
oioxo.com is the app. The desktop adds a real terminal, language plugins and — on Windows with an NVIDIA GPU — a native engine many times faster than the browser.
One optional account, for one reason: Pro on every device. Everything else stays on the device you are using.
Get the desktop appBuild something. It stays yours.
No card, no account to start. The model runs on your device — your code never leaves it.
