AI diagrams and technical design docs built from your code and systems
Generate architecture diagrams, flowcharts, sequence diagrams, and BPMN from a text prompt, code, Terraform, or an uploaded PDF, Word, Excel, PowerPoint, Draw.io, or Visio file.
Build interactive maps that sync with cloud accounts, repositories, and internal catalogs so the picture stays close to the real environment, with drill-down from org level to a single container.
Paste code or connect private and public Git repositories, Confluence, Notion, VS Code, and GitHub to keep diagrams grounded in actual implementation.
Run the agent toolkit in your own infrastructure under an MIT license and let MCP-compatible clients create, search, update, and export diagrams with OAuth or API tokens.
A visual knowledge base that turns scattered sources into a worldview you can build on
Split PDFs, web pages, YouTube videos, podcasts and Readwise or Zotero items into cards and read deeper through every citation.
Turn any goal into a personalised course and process readings with AI help before arranging ideas on the board.
Give your knowledge a structure that can be reworked as you learn, using nested tags and properties rather than flat folders.
Query your knowledge base from Claude Code, ChatGPT, Codex or Grok Bot through the plugin, MCP server and CLI.
