Chat with AI to draw diagrams — no syntax, no guessing at the details.
Draw a login flow. User enters email, then password, then a 2FA code. If 2FA fails, redirect to a reset page.
Try it →Sequence diagram: customer places order, gateway forwards to order service, order service writes to DB and calls notification service asynchronously.
Try it →Mind map for a SaaS launch: engineering, marketing, sales, support — each with 3-4 sub-tasks.
Try it →Draw the flow of user signup. Include email verification, password reset if forgot, and account lockout after 5 failed attempts.
Try it →The AI's clarifying questions help you think through actors, events, and edge cases you may have missed. Better than staring at a blank input box wondering where to start.
Multi-turn refinement lets you build up the diagram step by step. The AI tracks what you confirmed and what's still open, then draws everything at once.
Every generated diagram comes with a confirmation card listing anything the AI inferred. Reject anything wrong and the diagram redraws in seconds — no re-prompt needed.
Chat mode is great for group design sessions — start with a rough description, refine as reviewers point out gaps. The AI keeps the conversation context across turns.
Show a new team member how a system works by letting them chat with the AI to derive the sequence diagram themselves. Better retention than reading finished docs.
Chat mode is the antidote to one-shot AI generation. Instead of guessing what you meant, the AI asks 2-3 clarifying questions — who are the actors, what are the events, is the call synchronous or asynchronous — before drawing anything.
When the AI does draw, it also lists any assumptions it made in a confirmation card. If it added a return arrow you did not describe, an actor you did not mention, or a branch you did not intend, click Reject and the diagram redraws without that element.
Chat mode is best for complex flows where a one-shot prompt would miss important details — a login flow with edge cases, a sequence diagram with multiple services, a state machine with lifecycle transitions. Reach for it when you want the AI to help you think through what to draw, not just execute a prompt verbatim.
Everything else is the same as Quick mode — the same seven diagram types (flowchart, sequence, ERD, class, state, mindmap, Gantt), the same free tier, the same SVG / PNG / Markdown / OPML export. You can also mix the two: start with Quick to sketch a first draft, then switch to Chat to iterate on it. Both modes share the same underlying AI diagram generator.
