Turn any business into a single diagram.

One picture, shared by business and engineering.

Long AI explanations, scattered meeting notes and specs — they are hard to parse. Zukai converts them into human-readable structured Markdown and a diagram (SVG), both ways, and layers today and the future ((planned)) onto the same picture. Because the text is the source of truth, the diagram always updates and never drifts.

What you can do with Zukai

  • Readable Markdown ⇄ diagram

    Convert between text that reads as plain Markdown and a diagram, both ways. Edit the text and the diagram updates.

  • Shape it by chatting with AI

    Just say "add this step." The AI proposes the diagram source in the right notation — you decide what to apply.

  • Paste → diagram / file → diagram

    Just paste an AI's explanation. Or upload a text/Markdown/PDF file — meeting notes, a spec — and turn it into a diagram.

  • Folders, tags, full-text search

    Organize with folders, label across with tags, and find any diagram by full-text search. Sort, favorite, and archive to manage many at once.

  • Share links and export

    Hand off read-only access with an unguessable share link. Export to SVG / PNG / PDF — always free.

  • Cloud save and version history

    Save to the cloud and follow changes through version history. Revert to any past version non-destructively — history is never lost.

Turn text into diagrams with AI

Turn hard-to-read text straight into a diagram.

Zukai's AI is a modeling partner fluent in the notation. Three entry points turn text into a diagram.

  • Edit by chat — say "add an approval step to the order flow" and get a proposal back.
  • Paste → diagram — drop in an AI's long output or a bullet list and get a minimal, faithful diagram.
  • File → diagram — upload a text/Markdown/PDF file of meeting notes or a spec and turn it into a diagram.

Generated diagrams are always proposals — you decide what to apply. They are validated against the notation before they land.

Diagram the flow in these notes. Mark approval as "planned."
I built a draft of the order flow. The approval step is marked (planned). Apply it?
### Flow: Order

2. [Customer] places an order

Manage at scale

Manage a growing set of diagrams without losing your way.

The more your business grows, the more diagrams you have. Zukai's workspace gives you the tools to organize many diagrams and find them across the board.

  • Folders sort in a tree
  • Tags label across
  • Full-text search matches the body
  • Sort by updated / name
  • Favorites to open fast
  • Archive non-destructively

Three steps

  1. STEP 1

    Write, paste, or upload

    Write in Markdown, paste an AI's explanation, or upload a document file.

  2. STEP 2

    It becomes a diagram

    Preview on the spot. Shape it by chatting with AI; text and diagram stay in sync, always.

  3. STEP 3

    Save, share, manage

    Save to the cloud, share by link, export to distribute. Manage them all with folders, tags, and search.

Here is what you can draw

This is Zukai itself, drawn in Zukai's own notation. The readable Markdown on the left becomes the diagram on the right.

Markdown (excerpt)

# Zukai — self model

## Domain: core conversion

A core that converts Markdown ⇄ IR ⇄ {Markdown, SVG}, both ways.
The IR is the single source of truth.

### Flow: view the diagram and edit

- Phase: use
1. [Business/planning user] writes the model in Markdown
2. Call [parse] to convert it into IR
   - send: Markdown
   - receive: IR
3. Call [render] to turn it into a diagram
   - send: IR
   - receive: SVG

### Module: parse
- Responsibility: convert Markdown into IR
- Depends on: [IR]

Diagram (auto-generated)

The Zukai self model diagram. The domains — core conversion, account/storage, sharing, billing, AI, and integration/team (planned) — together with flows such as view-and-edit, save, share, edit-with-AI, and paste→diagram, all expressed as boxes and arrows in one overall diagram, grouped by domain.
