FAQ
Is OIOXO free?
Yes. The whole IDE, open models on your device and your own API keys are free without limits. OIOXO models (Light, Prime) are free within a 5-hour window with weekly and monthly caps; Pro ($3.99/mo or $39/yr) removes the window.
Is my code uploaded somewhere?
No. The model runs on your device and your files stay in your browser or your folder on disk. Our servers see token counts for the free allowance, a few usage beacons you can turn off, a problem report only if you send one, and Git traffic through the push/pull proxy, which does not store your token or your code.
Do I need a graphics card?
No. Without one the model runs on the CPU in your browser and a first turn can take minutes. With WebGPU it is several times faster, and the Windows desktop app with an NVIDIA GPU is faster still. Or add your own key and skip the download.
Can I use Claude or GPT instead of the local model?
Yes. Add an Anthropic key or any OpenAI-compatible endpoint (OpenAI, OpenRouter, Groq, Together, Mistral, DeepSeek, xAI, or Ollama and LM Studio on your machine) under Settings → Models & keys. Keys are free on every plan and talk straight to the provider.
Does it work offline?
Once a model is downloaded, chat and editing work without a connection. Sign-in, the free-allowance meter, Git push and pull, and your own keys need the network.
Does it work in Safari or on an iPhone?
With your own key, yes. The on-device engine does not run on Safari or iOS yet, so those tiers are keys-only today.
What can it build on its own?
Small on-device models build simple pages well and larger apps poorly, and the checks tell you honestly whether what it wrote runs. A bigger model or your own key closes the gap.
Can I work on my existing projects?
Yes. Open a folder on disk in Chrome or Edge (it is edited in place, nothing uploaded), import a zip, or clone a Git URL. Commit, push and pull from the Changes panel.
Who owns what I build?
You do. Code you create with OIOXO is yours — export it, publish it, sell it. See the Terms of service.
