1. Open the prompt box

Go to docdiagram.com. The prompt box sits in the middle of the page with the placeholder “Ask DocDiagram to draw…“.

​

2. Describe what you want

Be specific about the kind of diagram and the pieces involved. Good prompts name the components and the relationships between them. Examples that work well:

• “A sequence diagram showing a user signing in with Google OAuth: browser, our API, Google, and the database.”
• “An architecture diagram for a Next.js app on Vercel with a Postgres database and a Redis cache.”
• “An ER diagram with Users, Posts, and Comments. Users have many Posts, Posts have many Comments.”

Tips:

• Name the diagram type (sequence, architecture, flowchart, ER, org chart).
• List the entities or steps explicitly.
• Mention the direction of flow if it matters (“left to right”, “top to bottom”).

​

3. Generate

Press the submit button or hit Enter. DocDiagram renders the diagram and shows it to you in a chat-style editor.

​

4. Iterate

Not quite right? Tell it what to change in plain English:

• “Add a load balancer in front of the API.”
• “Move the database to the right.”
• “Use dashed lines for async calls.”

Each refinement is a turn in the chat. Your previous diagram stays in context.

​

5. Export

Click the export button and pick your format. See Exporting for what each format is best for.
