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.

Buy a prompt that already works - or sell the ones you have perfected.
Thousands of ready-to-use prompts organised by model and by output type, from illustration styles to marketing copy.
Listings are grouped by the model they were built for, so you can filter to the tool you actually use.
Each prompt is shown with example outputs, making it easy to judge the style before spending anything.
Anyone can upload prompts for sale and earn revenue share on every copy sold.
