Generated flowchart structuring the markdown headings and bullet hierarchy into a connected process diagram

What the AI produces

The "if failures" sub-bullets correctly become decision branches with loop-back to the previous step — a structure that's painful to draw manually but standard for deployment flows.

What is Markdown-to-flowchart conversion?

Paste a Markdown document — a README, a runbook, meeting notes, an RFC — and Flowova reads the structure (headings, ordered lists, fenced code, blockquotes) to extract the underlying process. Numbered lists become sequential steps; nested lists become branches; headings can scope a sub-flow. If your document already contains a Mermaid code block, that block is treated as the source of truth — Flowova renders the Mermaid directly rather than re-inferring from prose.

Convert Markdown to a Flowchart

1

Paste Your Markdown

Paste Markdown — ordered lists, unordered lists, or headings. The AI interprets list hierarchy and numbered sequences as flow.

  • READMEs, runbooks, RFCs, meeting notes
  • Numbered and bulleted lists become process steps
  • Existing Mermaid code blocks are used as-is
2

AI Extracts the Flow

Numbered lists become sequential steps; nested lists become sub-steps or sub-flows. Headings act as section dividers. Code blocks and inline code are preserved as labels but not parsed.

  • Headings can scope sub-flows
  • Conditional language ('if', 'unless') becomes diamonds
  • Code fences ignored unless they contain Mermaid
3

Export and Share

Edit to merge or split nodes if the AI's interpretation differs from your intent. Particularly useful for converting GitHub README sections or runbook docs to visual diagrams.

  • Free Mermaid export — round-trip back to your README
  • Edit visually without losing source compatibility
  • Free PNG; SVG is Pro for vector quality

Markdown to Flowchart Features

Structure-Aware Parsing

Reads heading hierarchy, ordered/unordered lists, code fences, blockquotes, and links — the structure of your markdown maps to the structure of the diagram.

Existing Mermaid Code Blocks

If your markdown already contains a ```mermaid``` block, that block is rendered directly — Flowova doesn't re-infer from prose when a source of truth exists.

Nested Lists → Branches

A bullet list with sub-bullets generates a tree-like branching structure. Three levels of nesting render cleanly; deeper nesting may need flattening.

Heading-Scoped Sub-Flows

A `## Section` followed by a numbered list generates a sub-flow scoped to that section. Useful for runbooks where each section is a sub-procedure.

Round-Trip via Mermaid

Export the resulting diagram as Mermaid (free), paste back into your README inside ```mermaid``` fences. Future renders stay in sync with the markdown source.

Skip Code Fences Other Than Mermaid

Code fences for `python`, `bash`, `json` are skipped — they're reference material, not procedure descriptions. Only `mermaid` fences are treated as source.

When to use markdown-to-flowchart

Use this tool for

  • GitHub READMEs that document a deploy process step-by-step — turn the numbered list into a visual companion for the repo.
  • Notion or Obsidian pages with structured procedures — export to .md, paste here, get a diagram for the same page.
  • GitLab runbooks where the headings and lists already encode the structure — the parser maps them to sections cleanly.
  • Documentation review — the diagram surfaces logical gaps that prose has been hiding for years.

Use a different tool for

  • Mermaid code blocks inside the Markdown — extract just the Mermaid and use Mermaid-to-Flowchart for those.
  • Free-form prose without lists or headings — Text-to-Flowchart handles unstructured paragraphs more naturally.
  • Word, PDF, or PowerPoint documents — use the matching file-input tool; pasting the raw extracted text drops semantic structure.
  • Multi-page wikis where the diagram needs to follow links between pages — flatten the relevant pages first, or build the visual map in Whimsical or Excalidraw.
