Concepticon — Thinking Tools Software<br>Skip to main content Concepticon<br>You might think your team has a ubiquitous language. You might want to check.<br>A concept map isn't a single diagram, it's any diagram you need, just when you need it. Concepticon turns plain-text propositions about your team's domain into a graph you can navigate at the size you can grok. Files stay on your disk, in plain text any editor — or any AI agent — can read.<br>Download for free Browse Sample Maps
📝<br>Plain Text Propositions<br>Write concept relationships in plain English ("Dog chases Cat"). No special syntax to learn — just words connected by words.
🗺️<br>Visual Graph Rendering<br>Propositions become an interactive force-directed graph. Pan, zoom, and explore your concept map with full mouse and keyboard support.
🤖<br>AI-Assisted Generation<br>Bring your own API key — Claude or GPT. Point the AI at a PDF, a web page, or a topic description; propositions come back for you to review and refine.
⌨️<br>Fully Keyboard Accessible<br>Every feature is reachable without a mouse. Screen reader compatible. Designed by a legally blind developer who uses it daily.
🔤<br>Works with Any Text Editor<br>Your proposition files are plain Markdown. Edit them in VS Code, Vim, Obsidian, or Notepad — Concepticon picks up changes automatically.
📚<br>Rich Concept Descriptions<br>Each concept can have a full Markdown description in a sibling file. View rendered descriptions as you navigate the map.
🔍<br>Focus Views<br>Zoom into a subgraph around any concept to reduce clutter. Explore neighbourhoods without losing the bigger picture.
📄<br>Import from Documents<br>Generate concept maps from PDFs, PowerPoint presentations, and web pages. The AI extracts key concepts and relationships for you.
🔒<br>Private by Default<br>Runs entirely on your machine. API keys are encrypted with OS-level secure storage. No telemetry, no cloud required.
How it works<br>Write propositions<br>Write relationships between concepts in plain text. Each line is a proposition: two or more concepts connected by a plain English phrase. Use any text editor, or — in Pro — create and edit propositions directly inside Concepticon.<br>Customer places Order<br>Order contains Line Item<br>Line Item references Product<br>Product belongs to Catalogue
Open in Concepticon<br>Point Concepticon at your propositions file. It reads the file and renders an interactive graph with automatic layout. Save the file and the graph updates instantly.
Explore and refine<br>Pan and zoom the graph, click concepts to read their descriptions, use focus view to explore a neighbourhood, and add AI-generated propositions from documents or web pages.
Build snapshots<br>Curate views of your map for onboarding new team members into the core concepts of your team's ubiquitous language. A new colleague — or a new AI agent — can self-serve their way into your domain in minutes. Snapshots can be defined in Pro, or hand-edited in any text editor.
The proposition format<br>Propositions follow a simple rule: one or more Concept Phrases connected by lowercase linking phrases. Concepts start with uppercase letters; linking phrases are lowercase.<br>Consecutive uppercase-starting words form a single concept (Harry Potter, General Relativity)<br>A lowercase word starts a linking phrase and ends the previous concept<br>Concepts can contain letters, digits, periods, and apostrophes (F.B.I., O'Connor)
Valid propositions<br>Dog chases Cat<br>Harry Potter attends Hogwarts<br>Claude Code applies AI to Software Development<br>F.B.I. investigates Organised Crime<br>Michael O'Connor lives in Dublin
