Model setup
Use Nugumi the way you already use AI.
Start with the setup that matches your privacy, quality, and cost needs. You can change it later.
Use your ChatGPT or Claude subscription
Good default if you already pay for ChatGPT or Claude and want strong cloud models.
Run locally with Ollama
Best when privacy or cost matters. Text actions can stay on your computer.
Connect your own API key
Use direct cloud providers when you want control over model, speed, and billing.
Questions, answered.
How is this different from ChatGPT or Grammarly?
Grammarly mostly fixes grammar. ChatGPT is powerful, but it lives in another tab. Nugumi sits next to the text or screen you are already working with and runs the right action from a click, so it sounds like you.
Where does Nugumi run?
You choose: ChatGPT or Claude subscription, local Ollama, or your own API key. Use Ollama for private local text actions. Use a cloud subscription or API key for stronger models and vision.
Can Nugumi understand websites or screenshots?
Yes. Ask Nugumi can read the visible screen when you explicitly ask a question like “What does this warning mean?” or “Where do I click?”
Is my screen sent to the cloud?
Only when you ask a screen question and use a cloud vision model. Text actions can run locally with Ollama.
Which apps does it work in?
Every app with selectable text: Slack, Gmail, Safari, Chrome, Notion, Notes, Mail, VS Code, PDFs, Discord, Telegram, and more.
Is Nugumi free?
Yes. Nugumi is free during early beta. You choose the model setup and any provider costs.
