Diagram as code: It supports a type-safe DSL and Mermaid.js syntax for defining diagrams.
AI assistant: Flowpilot AI lets users chat with a diagram in natural language to build and style blocks.
AI keys: AI diagram generation uses bring-your-own OpenAI or Anthropic keys, which the site says are stored on the user's device.
Privacy: The site describes storage as local-first, says diagrams stay on the user's machine, and says there is no cloud tracking or forced syncing.
Collaboration: Users can share a link and collaborate through peer-to-peer WebRTC with live cursors.
Figma: Diagrams can be copied into Figma as editable SVG and text layers, with no plugin required.
Exports: The site lists SVG, PNG, JSON, and MP4 exports, and its free plan also lists JPG export.
Auto-layout: Auto-layout uses ELK.js to route edges and align nodes.
License and hosting: The core engine is MIT licensed, and the site says users can host it anywhere and modify it freely.
