AI canvas
Use AI to think through ideas on your canvas.
Dia, Grein's AI assistant, works with the board you have open. Ask it about your notes, have it reorganize a messy board, or let Peek suggest what to look at next. Dia is on the Pro plan.
Ask about the board, not a blank prompt.
Open the AI panel and ask. Dia reads the blocks on the board you're on, including notes, links, files and images, so you don't have to paste your work into a separate chat.
To focus on one thing, right-click a block and choose Ask AI. Dia then answers about that block and anything inside it, and nothing else.
Have it make the changes.
Ask Dia to group notes into themes, outline a plan, connect related ideas, or build out a section with stock images. It plans the changes, then makes them on the board while you watch.
Everything it adds is ordinary blocks. Keep what helps, move it, or delete it, and undo works as usual.
It reads links and documents when you ask.
When a question needs a link, an uploaded document or a quick web search, Dia reads it and cites what it used. It only opens links that are in the conversation or on the board, and only when the answer depends on them.
Each reply can read up to 5 links and run up to 3 searches.
Peek suggests the next step while you work.
Turn on Peek and it looks at what changed on the board every few minutes, then offers one short suggestion when something would help. It works toward the project's description, so say what the project is for.
Choose how often it speaks up: Quiet, Subtle or Proactive. Peek is in beta and needs Pro.
What the AI can and can't do
- Plan
- Dia and Peek are on Pro. Connecting your own Claude or ChatGPT works on any plan.
- What it sees
- The board you have open and what's nested inside it. It doesn't read your other projects.
- Who gets it
- People who can edit the project. Viewers and visitors on a public link don't get Peek.
- Web reads
- Links and searches go through Jina AI. Files you upload are read by Grein's own servers first.
- Your data
- Grein doesn't use your boards, prompts or replies to train its own models.
- Chat history
- Your AI conversations are kept in your browser, and you can include them when you download your data.
From a messy board to a plan
One way to use Dia on a project that's still taking shape.
- 1
Get the material onto the board.
Paste links, drop in files and write rough notes. Don't organize yet.
- 2
Ask for the shape.
Ask Dia to group the board into themes and name each group.
- 3
Check the reasoning.
Ask what's missing, or what the strongest and weakest ideas are, and why.
- 4
Go deeper on one idea.
Right-click the block you care about and ask about just that.
- 5
Keep going with Peek.
Turn Peek on and let it suggest the next step as you work.
Questions, answered.
Dia and Peek are part of Pro. On any plan you can connect your own Claude, ChatGPT, Gemini or Perplexity account over MCP, or use your Claude or ChatGPT account in the desktop app.
No. Dia works with the board you have open and the boards nested inside it.
Grein doesn't use your content to train its own models and doesn't turn on provider-side training for its AI requests. The privacy policy has the details.
