No-code AI agents trained on your own business content
Responses are generated from your supplied content only, with a citation link attached to each answer so readers can check the source.
Create and configure custom GPT agents from a browser interface without writing any code or maintaining your own retrieval stack.
Ingest websites, help centers, PDFs, Office files, YouTube videos, podcasts and audio, across 1,400+ document formats and integrations like Google Drive and Notion.
Programmatic access to your agents through a documented REST API and SDK for embedding answers into your own applications.
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.
