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.
Analyze, optimize and organize prompts in one AI workspace
Describe a goal and get a structured, ready-to-use prompt, then convert it into a reusable template with variables and presets for future reuse.
See what works and what needs improving in an existing prompt, then let the optimizer rewrite rough drafts into stronger versions for your target model and format.
Reverse-engineer an image, video, URL or piece of text into a reusable prompt you can adapt for your own projects.
Save, tag and organize your best prompts, and track every version created through generation, optimization, refinement and reverse prompting.
