SPAICE

SPAICE replaces the flat document with a spatial canvas. Everything you create — a note, a code file, a function, an AI conversation, a drawing — becomes a node you can move, group, label, and connect. Because relationships between nodes are first-class, the structure of your project is visible rather than implied. A mindmapping mode adds grouping, guidance indicators, and structure review, while handwriting tools (pencil, highlighter, ink settings) let you sketch directly next to typed content.

An AI layer runs through the workspace rather than beside it. Each node can open its own Ask AI conversation with configurable model, provider, reasoning effort, tools, and behavior instructions; you can select several models to answer in parallel and compare results. Beyond single nodes, an agent can be pointed at the full Space, and 'Spaces within Spaces' let one canvas reference another. Nodes can be combined, analyzed, and sent for synthesis, so the AI works on the graph you built instead of a pasted wall of text.

The product also handles real code. You can create a project directory as file nodes, pull file functions into nodes, color-code and link files to their functions, and replace project code with node code — a workflow aimed at refactoring and architecture exploration. For hands-on work, a temporary, graph-scoped token lets a local agent such as Claude Code read and edit a specific Space, with editor or viewer permission and a one-to-24-hour expiry. Sharing, email invites, Spaces, an offline mode that syncs on reconnect, and an AI credits/billing panel round it out.
