DiagramBot — diagrams from prose

Write clearer technical posts. The ultimate diagram concept brainstormer.

Generate drafts of architecture and flow diagrams from plain English. Then use them as inspiration to draw your own diagrams.

Why DiagramBot

Fast drafts

One sentence → usable diagram. No design tools required.

Markdown-native

Copy a snippet and paste into any static site or CMS.

Made for developers

Readable visuals with sensible defaults and predictable outputs.

From idea to almost publish-ready diagram in seconds

DiagramBot turns a short explanation into a clear diagram concept for you to consider for your blog posts. Diagrams are what take your writing from average to "too awesome not to share" - trust us, we saw this happen with our Two Scoops of Django books.

Example diagram generated by DiagramBot — a simple architecture with frontend, API, and database

Above is a sample diagram generated with DiagramBot, about DiagramBot itself. As you can see, it's merely a starting point to generate concepts for you: it's got misspellings, technical and factual inaccuracies, and looks a bit like AI slop.

But that's okay! If you're writing something you care deeply about, it'll be worth it for you to spend 10 minutes remaking the diagram in the editor of your choice.

What creators say

"It's saving me hours coming up with fresh illustrations for Two Scoops of Django 6, which Daniel and I might actually get around to publishing now that we have this tool. Maybe? No promises, though, as I might just use that time to polish and improve DiagramBot."

— Audrey / "audreyfeldroy" , indie dev and book author

"I used to ask Audrey to make an image every time I blogged. Then I felt guilty and stopped. Now I can make my own blog post images, so my posts stand out on social media. I can also make tons of diagrams for the AIR docs."

— Daniel / "pydanny", AIR lead dev and Python blogger
