Select Scenario, Mind Map, Logic, or Org from the top mode switcher. Then open the sidebar Templates section and choose a ready-made template — or start blank.
Click the + button on the tool rail (left side) for the Quick Add menu — or use keyboard shortcuts: N for a node, T for a text box. Drag from the canvas to any empty area to create a node inline.
Hover over any element to see 8 blue port dots (N/S/E/W + 4 corners). Click any port dot and drag to another element's port dot to create a connector. Or press C for connector mode, click source, then target.
Double-click any element to open the floating editor. Use the Content / Style / Size / Actions tabs. Changes apply instantly. The context toolbar above a selected element gives quick access to color, shape, font size, bold, and italic.
Hover or click any line to reveal the mini-toolbar: label, color, curve type (Bezier/Smooth/Straight/Elbow/Step), arrow end style, and dash style. Double-click a line to add or edit its label directly.
Press 💾 Save to store locally. Click 🔗 Share to copy a shareable URL (no server needed). Use ↓ Export for a JSON backup or 📷 PNG for an image.
Every element type is available from the Quick Add menu (+ button on the tool rail) or the sidebar Add Items section.

Get your diagram out in the format you need.
Exports the full canvas as a high-resolution 2× retina PNG. Click 📷 PNG in the toolbar. Requires the html-to-image library to load (needs internet connection first time).
Use your browser's built-in Print dialog (Ctrl+P / ⌘P). The diagram fills the page with all UI chrome hidden. Works in all modern browsers.
Click ↓ Export for a portable .json file. Import it on any device with ↑ Import. This is the safest long-term backup format.
Click ↓ Self-Contained to embed all remote image assets into the JSON as base64. The file is self-contained — opens offline with no broken images.
Click 🔗 Share to copy a URL that encodes your entire project. No server required — the state is compressed into the URL hash using LZ compression. Share via email, Slack, or any messaging tool.
Click 📋 Review to export all reviewer comments with severity, status, and timestamps as a structured JSON file — ready for tracking in your project management tool.
Connect your own API key and let AI accelerate your diagramming.
Describe your scenario, process, or topic in plain text. The AI creates a structured diagram with nodes and connections automatically placed on the canvas.
Select any node and ask the AI to expand it with sub-ideas, consequences, action steps, or related branches. New nodes appear connected to the selected one.
Convert your entire diagram into a structured text outline — useful for turning a brainstorm or scenario into a document draft, course outline, or presentation deck.
Supports Claude (Anthropic), ChatGPT (OpenAI), and Gemini (Google). Your API key is stored only in your browser's localStorage — never sent to any server except the AI provider's own API.
The most detailed compliance scenario templates in any free diagramming tool.
Compliance templates include references to GDPR Articles 33–34, Bribery Act 2010, PIDA 1998, Fraud Act 2006, and Employment Tribunal procedures.
Branching scenario mode is designed to mirror SCORM-style decision trees. Export as JSON and import into your authoring tool, or use the presentation mode for direct delivery.
Use Review Notes and Comments to gather SME feedback directly on the diagram. Filter to unresolved comments. Export a review report for sign-off tracking.
Use Logic mode to map actual policy workflows — approval chains, escalation trees, exception handling — then validate them with subject matter experts before publishing.
Drawing, presenting, theming, layers and image editing — all free, no sign-up required.
Sketch directly on the canvas with the Draw / Pen tool (shortcut D). Pick from six pen colors and a 1–14px width slider. The eraser removes individual strokes. Drawings pan and zoom with the canvas and save with your project.
A glowing red dot (shortcut L) follows your cursor while presenting, drawing attention without leaving any permanent mark — ideal for live walkthroughs and remote demos.
Switch the whole canvas look from the 🎨 theme picker: Grid, Paper, Big Dots, Mint, Blueprint, or Plain — plus a full dark mode. Your choice is remembered across sessions.
One click recolors every node in a coordinated sequence. Choose Classic, Pastel, Vibrant, Ocean, Forest, Sunset, or Slate to instantly restyle a whole mind map to match your brand or mood.
Select an image node and click the crop button to zoom, drag-to-reposition, toggle fit/fill, and fine-tune brightness, contrast, saturation and grayscale with a live preview. Hide the caption for a clean photo tile.
Control stacking from the context toolbar: bring to front, bring forward, send backward, or send to back. Overlapping nodes, shapes and images sit exactly where you want them.
Click ✦ Output to convert your map into a Slide Outline, Agenda, Project Plan, Checklist, or Summary Brief. Copy the text or download it as a .txt — turn a brainstorm into a deck or doc in seconds.
Align node text left, center, or right from the context toolbar, and lock any element to prevent accidental moves or resizes. Multi-select with Shift+click to move groups together.
Apply a clip-path shape — diamond, hexagon, star, triangle, arrow, parallelogram, trapezoid or document — and the text now centers and auto-shrinks to stay neatly inside the shape, never spilling outside.
.mm files, then use ⬇ .mm Import (toolbar) or the Gallery's "Import .mm / OPML" card to bring it in.
