RESEARCH NOTES
What this tool actually does.
Whimsical is a collaborative visual workspace positioned as 'the whiteboard for product builders.' Its core offerings include flowcharts, mind maps, sequence diagrams, wireframes, sticky notes, and freehand drawing on an infinite canvas. Key features highlighted by the vendor: predictive shapes and keyboard shortcuts for faster diagramming; automatic mind-map layouts with movable branches and links to files/tasks; real-time multiplayer editing; image uploads and embedded videos (Loom, YouTube); version history with restore; workshop tools such as timer and voting; integrations with Notion, Jira, and Slack; and 'Whimsical AI' powered by Claude that generates editable flowcharts, mind maps, sticky notes, and other diagrams from prompts. Whimsical is aimed at product teams for ideation, user-journey mapping, process documentation, UI wireframing, and competitor research. No pricing, foundin

Build a web-based collaborative diagramming tool inspired by the core workflow of Whimsical: teams ideating, mapping processes, and shaping UI together on an infinite canvas. The product must support four diagram types — flowcharts, mind maps, sequence diagrams, and simple wireframes — created on an infinite canvas with grids, pan/zoom, and sticky notes. User-facing requirements: drag-and-drop nodes from contextual shape libraries; predictive connector suggestions when hovering near node edges; keyboard shortcuts for common actions; automatic mind-map layout with manually draggable branches; inline linking of nodes to URLs or external tasks; real-time multiplayer editing with visible cursors, presence, and comments; version history with restore; optional voting and timer toolbars for workshops; image upload and video embed (YouTube/Loom-style iframe); AI text-to-diagram generation that returns editable nodes (flowchart and mind map only); and read-only share links with role-based permissions. Technical requirements: React + TypeScript frontend; tldraw or custom Canvas/SVG renderer; yjs or similar CRDT over WebSocket for multiplayer; node-graph data model storing node types, connectors, layout, and metadata; Postgres for persistence; API routes for boards, version snapshots, sharing, and AI generation; server-side AI calls proxied through an LLM endpoint. Implementation approach: prioritize the node-graph engine and multiplayer sync first, then the four shape renderers, then AI generation as a best-effort feature with graceful fallback. Explicitly do not copy Whimsical's branding, logo, exact color palette, layout, or visual style — create an original aesthetic. Out of scope: native mobile apps, offline mode, presentations, advanced UML/ERD modeling depth, pixel-perfect high-fidelity wireframing, billing/subscriptions, enterprise SSO, and mobile app design export. Deliver a README documenting setup steps (env vars, DB migration, WebSocket server), architecture overview, the AI integration approach with key limitations (rate limits, prompt-injection risk, hallucinated node text), and known constraints such as conflict resolution guarantees and scalability trade-offs of the chosen CRDT.
