Keep talking while the diagram takes shape
An approval process rarely ends with a straight line. Someone requests a change, a reviewer sends it back, and a second person needs to sign off. Describe those details to the AI diagram generator as they become clear.
Your first message opens a workspace with the conversation on the left and your diagram on the right. The agent can ask about a missing decision before drawing. Once a result appears, point to the part you want to change and continue in the same conversation.
“Add a revision step when the reviewer requests changes.”
The updated flow shows where the request returns and what happens after resubmission. Select a label to rename it, adjust a color yourself, or ask for another change. Earlier versions remain available when you want to revisit a decision.
Illustrative workflow: brief → assets → review → schedule → launch → measure. Changes requested at review return through a revision step to assets.
See different ways to explain the same work
A launch overview, a system architecture and a data chart each need a different arrangement. Tell the AI diagram generator what your reader needs to understand.
Explain a process
Follow a launch from the initial brief through review and publication. Decisions and return paths show what happens when work needs another pass. Use the overview to introduce the process, then focus on one branch during a discussion.
Show how a system fits together
Place services inside clear boundaries and label the connections between them. A reader should be able to trace a request, see where data is stored and identify which external service a component depends on.
Make a comparison readable
Give the agent your values and the comparison you want to explain. Keep labels, units and the underlying numbers visible. Ask for a different chart when another view makes the relationship easier to understand.
Bring the material you already have
Use the AI diagram generator with a paragraph of notes, a screenshot or a document. Tell it which part matters and who the diagram is for.
For an image, the agent interprets visible labels and relationships and redraws them as an editable diagram. A clear photo helps. If an arrow or handwritten word is ambiguous, you can clarify it in the conversation.
Sign in to work from PDF, Word or Markdown files, or import supported Mermaid, draw.io and Excalidraw files. Your account's file limits apply. Source imports and screenshot interpretation follow different processes; neither promises perfect reproduction.
Before launch, the brand team reviews the assets. If they request changes, revise and resubmit. Approved work moves to scheduling.
What can you make with an AI diagram generator?
You can name a format or let the agent suggest one from your brief. Explain whether you need to show an order, a relationship, a hierarchy or a comparison.
- Flowcharts and swimlanes: What happens next, and who handles each step?
- Architecture and data flow diagrams: What connects, and where does information move?
- Sequence diagrams: Which participant sends each message, and in what order?
- ER diagrams: How do entities relate to one another?
- Org charts and trees: How are people or ideas arranged?
- Timelines and Gantt charts: When does the work happen?
For numerical charts, supply the values you want represented. Missing figures need clarification before they can become a meaningful comparison.
Ask for the set of diagrams your task needs
A long brief may need an overview and several detailed views. Tell the AI diagram generator what you need to deliver, including a quantity if you have one in mind.
“Create a system overview, a login sequence and a data flow diagram for this product.”
The agent plans the requested set in one conversation. You can switch between results and ask it to update related diagrams together. Available credits, storage and task complexity still apply. A document’s page count does not automatically determine how many diagrams you receive.

Use your brand colors when you ask
Save named palettes and choose a default. Tell the AI diagram generator to “use my brand colors,” or name the palette for a particular client.
You can keep several palettes in your account and edit them later. Existing diagram versions retain the colors used when they were saved. If you have not requested a brand palette, the agent chooses colors suited to the diagram’s style and content. The website’s colors do not dictate your exports.
Your diagrams can have their own colors.
Pick up a project where you left it
Keep related conversations, source files and diagrams in a personal Project. Your AI diagram generator can draw on permitted project context when you continue the work, so a new conversation can refer to an earlier diagram or a decision you already made.
Memory settings let you review, correct and delete remembered information. Project boundaries control where context may be used. A client’s brief should not silently become a rule for every other project.
History gives you a separate view of your saved results. Each diagram has one card showing its latest version, with earlier versions grouped underneath. Open a result to return to its conversation and continue editing.
Export a result that fits the handoff
The AI diagram generator supports PNG for placing an image into a document, SVG for scalable graphics, PDF for page-based delivery and standalone HTML for viewing in a browser. You can also create a read-only sharing link and revoke it later.
Select several diagrams for a PDF when a single page would hide useful detail. Review the saved version before exporting so the file reflects the changes you intend to share. Public links expose the selected result, without sharing your private conversation or source files.

Questions before your first conversation
Is this AI diagram generator free?
Yes. Try one guest diagram for free, then create a free account for signup credits and daily credits. AI use is limited by your available balance. When it runs out, use the next daily allowance, buy credits or subscribe.
Can I try it without signing up?
Yes. Start with text or one image, without an account or credit card. Sign in to save the result, continue editing or work from documents. Guest work is temporary.
Can an AI diagram generator redraw a screenshot exactly?
It can interpret visible structure and redraw it. Exact pixel matching is not guaranteed. Check important labels, arrow directions and relationships before using the result.
Can I edit the result directly?
Yes. Select supported elements to change text, colors or positions. Use the conversation for larger changes, including revisions that affect several diagrams.
Can I export diagrams for free?
Yes. Registered users can export PNG, SVG, PDF and HTML or create a sharing link without a paid subscription. Exports use no AI credits. PowerPoint, draw.io and Mermaid source exports are not included.
Are my diagrams published automatically?
No. Saved work is private by default. You choose when to create a read-only sharing link and can revoke access through that link.
