Which Languages Does AI Draw Support?

Short answer: the interface comes in five languages — English, Deutsch, Français, Español, and 日本語 — but your prompts can be written in pretty much any language. Those are two separate things, and mixing them up is the one real gotcha here.

What the UI language actually controls

AI Draw is a web app that turns plain-language descriptions into real, editable draw.io diagrams — flowcharts, UML, sequence diagrams, cloud architecture, org charts. The buttons, menus, and settings of that interface follow the language of the site navigation, or the language you pick in the app’s own Settings. That part is the app’s doing: the UI translations are ours, not something the AI generates on the fly.

What happens to the labels in your diagram

Here’s the nuance. The text inside the shapes does not follow your interface language. It follows the model’s interpretation of your description. If I write a prompt in German, I expect German labels in the boxes — and in my experience that usually happens. The model tends to mirror the language I used. Write mostly in one language, and the labels stay consistent with it.

The honest limitation: mixing languages in a single prompt can confuse it. Something like “user logs in, dann prüfen wir die Daten, then send email” will often produce a diagram where one box is English and the next is German. It rarely breaks the structure, but it looks messy, and a few boxes will need renaming. I’ve also seen a French prompt produce an English label for technical terms like “Server” or “Login” that exist in both languages — the model just picks whatever it thinks fits. That’s on the model, not on you, and it’s easy to fix because every shape stays editable.

Practical notes

• Prompts: any language. I’d stick to one language per prompt for the most consistent labels.
• Mixing languages: works, but expect occasional mixed labels — an interpretation, not a guarantee.
• Exports: PNG, SVG, or .drawio source, editable in any draw.io-compatible tool, so renaming labels after generation is quick.
• Replication: upload an image, screenshot, or PDF of an existing diagram and ask the app to replicate it; labels in your source usually carry over as-is.
• Translation requests: you can ask the model to translate a diagram, but the result is an interpretation. If exact wording matters, proofread before you export.

Language and the rest of the product

Language doesn’t change anything about how you get diagrams. The free tier still gives you 3 diagrams a day with no account, and the Pro Pass ($9.90 / 30 days, access code by email) still lifts the daily cap. Your prompt text goes to the AI provider (DeepSeek) only for generation, and the rest of your diagram data stays in your browser — the privacy FAQ spells it out. If you’re new to the whole thing, the what-is-ai-draw article is a better starting point than this one.

So, to wrap up honestly: five interface languages, effectively unlimited prompt languages, and labels that follow your description most of the time. The least surprising setup is one language per prompt. Everything else is fixable afterwards anyway. Go ahead and open AI Draw and write a prompt in your own language — that’s the fastest way to see how it behaves.
