Atlas

Clear system diagrams

Ask your AI to draw how something works and get one readable page back: a one-sentence claim, short text, and diagrams that follow fixed rules. It picks the right shape for each question, and it splits big systems up instead of drawing one giant tangle.

Real output: figures drawn by Atlas for an invented bike rental shop. See the full example page.

What you get

  • One self-contained HTML page you can send to anyone
  • Line maps, data models, sequences, calendars and journeys
  • Scripts that lay out the figures and check them
  • Large systems split into groups, so they stay readable

What you need

  • An AI tool that can use skills, such as Claude Code
  • Node.js for the layout scripts

Data models, sequences and calendars are drawn with Pele by kepano (MIT).
