How it works
From scattered notes to clear answers
Nodi keeps you in control: you shape the board, the AI reads it and shows its work.
- 01
Capture everything on one canvas
Double-click anywhere to add a note. Give it a type and color so the board reads at a glance.
- Observations, findings, metrics, ideas, questions
- Projects with as many boards as you need
- 02
Connect the dots
Drag from one note to another to link them, and name the relationship.
- Supports, contradicts, raises, details…
- See how evidence and ideas relate
- 03
Summarize with sources
One click turns a board into a structured summary. Every key point lists the notes behind it.
- Overview plus numbered key points
- “Show all on canvas” jumps to the sources
- 04
Ask your board anything
Chat with your notes. Answers quote your evidence and cite the exact notes they used.
- Follow-up questions keep the context
- Answers in your language

Less sorting through notes. More thinking about what they mean.
Privacy
Your notes, your keys
Nodi is built so that you decide what the AI sees and who pays for it.
Keys encrypted at rest
API keys are encrypted on the server (AES-256-GCM) and never sent back to the browser. You only ever see the last four characters.
Your data stays yours
Every project, board and note is tied to your account and isolated by row-level security in the database.
The AI only sees what you send
Only the board — or the selection — you analyze goes to the provider you chose, with your own key.
FAQ
Questions, answered
Do I need an AI subscription?
You connect an API key from Claude, OpenAI, Gemini, OpenRouter or Hugging Face in Settings. You pay that provider directly for what you use, and OpenRouter also offers free models.
Which AI models can I use?
Any model your provider offers that supports structured answers. Each connected provider has a searchable model picker, with prices and context size when the provider shares them.
Does it work in Spanish and other languages?
Yes. The AI answers in the language of your notes, or in the one you choose: English, Spanish, Portuguese, French, German or Italian. The interface is in English.
Can I use it on several devices?
Yes. Sign in with Google or with email and password, and your projects and boards sync to every device you sign in on.
What happens to my API key?
It is encrypted on the server and only used to call the provider on your behalf. It is never shown again in full, and you can remove it at any time.
