AI-Generated Blog Diagrams

Description and use

Automated blog diagram creation using local tools and AI, ensuring stable, editable images without token costs.

Problem

Creating rich, stable, locally generated blog diagrams from text descriptions without expensive hand‑drawing or token‑heavy image models.

Outcome

Authors can produce stable, locally generated diagrams with minimal friction, avoiding token costs and ensuring reproducibility.

Workflow

• Write a concept.md outline with plain text and figure briefs.
• Insert a figure brief describing content, layout, emphasis, and size.
• Run the local AI pipeline to generate a PNG from the brief.
• Review and edit the image if needed.
• Replace the brief with the generated image in the markdown.
• Repeat for subsequent figures.

Evidence

I used to make diagrams with Mermaid: drop a code block into Markdown and a figure appears.

Mermaid would struggle with figures like these. Dragging boxes in an online tool burns your fingers.

With a local pipeline the artifact is a file on disk: fix it by hand (re-render) or say what to change — the next run stays stable.
