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.
An AI calendar you talk to — schedule, update and share your time in plain language.
Add and change events by typing or speaking plain instructions, such as scheduling lunch or moving a meeting, instead of filling out forms.
Share a booking page that reads your real-time availability, respects time zones, and offers only slots you are genuinely free for.
Neocal checks your calendar before booking so invitees and clients never double-book you.
Chat with your calendar in WhatsApp to create, update or confirm events without switching apps.
