Is AI Draw Free to Use?

The direct answer: yes, it’s free to use

Yes — AI Draw genuinely has a free tier, and it’s not a trial. You get 3 diagrams a day, no account, no credit card. Open AI Draw, describe a diagram in plain language, and generate.

If you’re new to it, here’s what AI Draw actually does: it turns plain-language descriptions into real, editable diagrams — flowcharts, UML, sequence diagrams, cloud architecture, org charts. The free tier gives you the full generator, not a crippled demo.

What happens when you hit the 3-per-day cap

To be fair, the cap is real, and you will hit it if you draw a lot. Honestly, three a day is plenty for most people — but when you need more, you have two ways past the limit:

• Pro Pass — $9.90 / 30 days. A flat one-time purchase for a month, not a subscription. The access code arrives by email, you enter it in the app, and the daily cap lifts. No auto-renewal, nothing to remember to cancel.
• BYOK (bring your own key). In Settings you can add your own AI API key and use the app as much as you want, paying your own provider directly. Meant for people who already have an API account and know what a token costs.

Which one suits you depends on how often you draw. In my experience, the free tier carries most casual users — one flowchart for a meeting here, one org chart for a doc there — because most people don’t produce three diagrams a day, let alone every day. If you generate multiple diagrams daily for work, the Pro Pass pricing is a flat $9.90 for 30 days, and since there’s no auto-renewal, it costs you nothing the months you don’t need it. More details on the Pro Pass here.

The honest limitations

Let me be straight about the tradeoffs so nothing surprises you later. The free tier is capped — if you use your third diagram at 9 a.m. and need a fourth at noon, you wait for tomorrow, buy a pass, or set up BYOK. There’s no hidden way to squeeze out a free fourth. The Pro Pass is 30 days, not a lifetime unlock. And the output is an AI’s first draft, not a promise: expect to nudge a label or two before a diagram is ready to show anyone. That’s normal, and because everything is standard draw.io format, editing is straightforward.

What the free tier includes

Worth repeating: free doesn’t mean feature-limited. Even without paying, you get exports as PNG, SVG, or .drawio source (editable in any draw.io-compatible tool), you can upload an image, screenshot, or PDF of an existing diagram and ask the app to replicate it, and you can write prompts in any language — the diagram labels usually follow the language of your description. The interface itself comes in English, Deutsch, Français, Español, and 日本語, following the site navigation language or the app Settings.

And about your data

Since “free” makes some people suspicious, here’s the short version: your diagrams live in your browser (localStorage), not on our servers. Prompt text is sent to the AI model provider (DeepSeek) only for generation, and uploaded images or PDFs are used only for the replication request and are not kept. No data resale, no content mining. That applies to free users exactly the same as everyone else.
