How it works

How to generate an AI flowchart

Tips on generating a flowchart
  • If applicable, instead of writing a prompt from scratch, consider pasting excerpts from existing requirements docs, call transcripts, knowledge base articles, code (e.g. scripts), or uploading image files.
  • Working with an LLM to create a fleshed-out diagram prompt can be effective. Ask it to describe a flow as a nested list.
1

Write a prompt describing a flow

Describe a flow — a user flow, data flow, or business process. Writing the prompt as a nested list works well, since it maps cleanly to the branching nature of flowcharts.

  • Clearly describe the key structural components: start nodes (where the flow begins), end nodes (where it ends), and decision nodes (where it branches).
  • If applicable, call out natural groupings — system boundaries, or phases and states in the flow.
  • Instead of writing from scratch, paste excerpts from requirements docs, call transcripts, knowledge-base articles, or code.

Generate a diagram

Run the completed prompt through the generator. Eraser AI converts it into a structured flowchart with clean layout and routing in seconds.

3

Edit with follow-up prompts

Refine the result conversationally — add steps, rename nodes, or restructure branches. This step requires signing in to Eraser.

4

Manually adjust the layout

Drag nodes and fine-tune spacing, line styles, and grouping with GUI controls for a presentation-ready result. This step requires signing in to Eraser.
