I like the wonky, hand-drawn looking style. I think it fits well beause usually if I use a diagram it's not 100% precise and accurate, but more a high-level illustration. The wonky style conveys the approximate precision of the presented concept.

Also, and that's personal, I think it's cute.

This looks really clean, nice work. I’ve had the same issues with most diagramming tools, it's either not so good looking or the insane pricing .

I went a different route using diagram-as-code with Mermaid instead of manual drawing.

In Excalidraw, you can reduce (and completely remove) the "sloppiness" in the element properties.

When a background shape is in focus it comes to the foreground covering the shapes that are on top of it.

> It looks off

Depends on what you want to achieve with your look. Do you want to scream professionalism, authority, and completed? Use a regular UML tool.

Want to say this is a rough draft of a few ideas? Then using UML is probably THE wrong look. And Exaclidraw should be used instead.

--- Anecdote time. According to one of my professors, they showed how the prototype will look in action, and the customers were so impressed by the smoke and mirrors prototype they wanted to start using it right away.

In the end, customer walked away because they thought they were being strung along to pay for something that was already done.

looks awesome man !

Author here: I use mermaid lot as well and for some things like process flows, and to model interactions it it outrules excalidraw and posts will follow where i need exactly that. but to visualize things high level i find excalidraw way nicer.

Author here: Haha - yeah that is kind of meta - i know. Other content will be more about the acutual problems i solve. Check out https://blog.lysk.tech/sqlite-on-git-prologue ;-)

Whiteboard handwriting is childish?

Thanks for the flowers

AI can generate mermaid diagrams, not excalidraw. If you use the mermaid to excalidraw, i guess it can be, but it just looks like a mermaid diagram then and not an excalidraw.

I use the Obsidian Excalidraw plugin, means I can add diagrams to notes without leaving Obsidian.

I didn't have good experience with excalidraw-mcp when it first came out a month ago; the Claude-generated diagrams were too raw/unpolished. I'm sticking to mermaid for now but I'm interested in hearing how people make exclidraw-mcp work for them

Thanks for the hint - just updated the post and adde the attribution

Apparently Excalidraw is An open source virtual hand-drawn style whiteboard. Collaborative and end-to-end encrypted.

Pretty new to hn, thanks for the hint

I've always liked umlet and umletino (web version) for a nice mix of drag and drop and edit by text editor. In the absence of good enough layout algorithms, the ability to manually drag things to the right place is kind of essential. The resulting diagrams are not so pretty of course.

I have tried a lot of tools in this space. If it comes out looking alright, that's usually because it was so simple that it didn't actually need a diagram. Anything with a bit of non trivial structure seems to quickly escalate with essentially no good options other then esoteric hacks with styling to make it look any good.

This seems to be a thing where you can have pretty automated layouts, complex diagrams, or correct diagrams and can only have two out of three.

Which means that almost 100% of my use cases for these tools never really work for me unless I sit down and grab some old school drawing tool (or just give up on the whole notion, which is much more likely). If it was trivial, I wouldn't bother making a diagram. These tools seem only usable for stuff where diagrams were overkill to begin with. I saw no examples on the linked article (and the rest of the site; I browsed the top few recent articles) to really counter this.
