Reading sources
PDF passages, annotations, and knowledge cards
Document Reader · Online Whiteboard · Mind Maps
Read documents. Connect ideas on a whiteboard. Build knowledge with mind maps.
Move from reading to synthesis in one workspace: import PDF and EPUB documents, currently work with parsed PDF sources, connect ideas on an online whiteboard, then organize them in an editable mind map.

REAL CAPABILITIES
Read documents, connect sources, and shape knowledge in one continuous workspace.
The document reader, online whiteboard, and mind maps share one knowledge space, so source reading, visual synthesis, and output stay connected.
Document reader
Import PDF and EPUB documents. Parsed PDFs currently support source-grounded questions, annotations, and knowledge cards, with more formats to follow.
Explore Document ReaderOnline whiteboard
Use drawing, text, images, structured nodes, and connectors to place source material and loose ideas on one freeform canvas.
Explore Online WhiteboardMind maps
Use editable hierarchy, layouts, themes, and an outline workflow to turn complex knowledge into a clear branch structure.
Explore Mind MapFrom reading to knowledge
Not three disconnected tools—a continuous flow from source to structure.
Rainbow Roadmap turns reading, distillation, connection, and organization into four linked actions that can always return to source material.
Read and ask
Import a PDF or EPUB. Parsed PDFs currently support page reading, annotations, and source-grounded AI questions.
Collect knowledge cards
Turn key passages, notes, and answers into reusable cards for synthesis.
Connect on a whiteboard
Move, draw, connect, and enrich material until relationships become visible.
Organize with a mind map
Shape complex ideas into an editable mind map, then save, share, or export the result.
Whiteboard examples
Different goals can all begin with one clear path.
These are product examples, not invented user data. They show the real kinds of work a whiteboard can hold.
Example
Language basics
Framework practice
Ship a project
Frontend growth path
Connect knowledge, practice, and portfolio work into a learning path that keeps moving.
Example
Validate demand
Iterate prototype
Launch and review
Launch an AI product
Keep product decisions and delivery aligned from problem discovery to launch.
Example
Define scope
Complete build
Launch and iterate
Ship an independent project
Keep scope, milestones, and risk on one execution map that stays current.
CHOOSE THE RIGHT TOOL
Built for deep reading and visual synthesis, with clear capability limits.
The workspace connects sources, notes, and structure. Professional OCR correction, publication layout, and real-time co-editing still need specialized tools.
A good fit for Rainbow Roadmap
- Import PDF and EPUB documents, then ask, annotate, or distill ideas from parsed PDF passages
- Connect documents, ideas, images, and structured nodes on a whiteboard
- Organize learning and research outcomes in editable mind maps
Use a specialized tool when you need
- Professional OCR correction or exact reconstruction of scanned layouts
- Publication-grade PDF typesetting or editing original PDF page content
- Real-time co-editing or a full project-management system
SHARE AND EXPORT
Make a whiteboard viewable, copyable, or ready to take with you.
Sharing keeps a read-only boundary, and exports use formats the product genuinely supports—not vague collaboration claims.
Public read-only links
Owners can explicitly make a whiteboard public so anyone with the link can view it anonymously while the original stays read-only.
Copy into a personal workspace
After signing in, a viewer can copy a whiteboard into their own workspace and edit it independently without changing the original.
High-resolution PNG export
Export a high-resolution PNG for presentations, reports, or long-term reference.
