The board has no fixed page size, so a session can grow from three notes to sixty without hitting a wall. You pan and zoom to work at either scale, and layout stays where you put it. That freedom costs structure: a board left alone for a week turns into a pile unless you name blocks and group them early.

Each block holds its own conversation, and you add one by dragging it from the toolbar. Questions and answers stay attached to the block, which makes an AI canvas behave more like a wall of index cards than a chat log. The approach suits comparison work, where the value comes from seeing several answers at once.

Plain notes and image layers live on the same surface as the AI blocks, with upload limits of 1MB, 4MB or 8MB depending on plan. A screenshot can sit directly under the prompt that produced it, so evidence and claim stay together. This is the part that turns the tool from a chat wrapper into an AI whiteboard for real project material.

Several people can edit one board at the same time and see each other's cursors. Edits appear without a refresh, which matters during a live session where someone is talking and someone else is capturing. The free plan allows a single team; Starter raises that to ten and Business removes the cap.

Boards are searchable, so an old decision is findable without scrolling through weeks of canvas. Layers can be stacked up to 200 on the free plan and 1,000 on Starter, which is enough for a dense workshop. Structure is manual by design, and that is the honest trade: the tool gives you room, not an automatic filing system.

Token-based pricing runs through coins, with each model carrying its own input and output cost. You buy coins when you need them, and unused balance carries over indefinitely. For occasional users this is cheaper than a monthly seat. For daily users the meter runs with no volume discount, so watch the balance during long sessions.
