Features

Edit the diagram as a living object, not a static SVG.

Click-to-edit diagrams

Select flowchart and sequence elements from the SVG and sync the exact source lines.

Scoped AI changes

Ask for whole-diagram improvements or selected-node edits with a safe apply/discard review step.

Template registry

Start from typed templates today and add new chart families through the same registry later.

Traceability-ready

The product architecture leaves room for PRD evidence mapping without forcing it into v1.

Source trace

Ready for document-backed diagrams.

v1 focuses on the Mermaid editor. The architecture keeps diagram elements, source lines, and AI context structured so PRD evidence mapping can be added cleanly later.

Users upload a product requirement, the system proposes a flow, and each generated node can point back to supporting text.

FAQ

Questions users will ask before trying it.

Does it replace Mermaid syntax?

No. Mermaid source remains the source of truth, so diagrams stay portable.

Which diagrams are visually editable?

Flowchart and sequence diagrams in v1. Other types render and export from code.

Can AI change only selected nodes?

Yes. Selected diagram elements are sent as scoped context to the AI route.

Can templates expand later?

Yes. Templates live in a typed registry that can grow by diagram family.

Build diagrams your team can edit, verify, and trust.

Open the editor, pick a template, and start shaping Mermaid visually.
