AI diagram generator
Paste text, get the right diagram — and check every node
Steps become a flowchart, a hierarchy a mind map, figures a chart, a plan a Gantt chart, causes a fishbone, a comparison a Venn diagram. Leave it on Auto and it picks, and tells you why.

An employee submits an expense claim, and their manager approves it. Claims over $500 also need a review by the finance director. Finance then checks the receipts: if any are missing, the claim goes back to the employee; if they are complete, the cashier pays out and the process ends.

Pick the diagram
Each type has its own page with examples. All of them open the same editor.
Notes, summaries, a topic with several sides.
Steps, approvals, decisions — swim lanes for several roles.
Departments, teams and reporting lines.
Bar, line and pie charts from figures or a table.
Tasks, durations and dependencies.
Dates and events in order.
A problem and its causes, grouped.
Strengths, weaknesses, opportunities, threats.
What two or three things share.
Pyramid, funnel, cycle, steps, key numbers.
Four steps
Paste the text
Notes, a process, a plan, a set of figures — up to about 8,000 characters.
Leave it on Auto, or pick a type
Auto reads the content and says under the diagram why it chose that type.
Check and adjust
Click a node to see its sentence; change type or revise in a sentence.
Export
Word, PDF, PNG or SVG — or copy it as an image.
Check every node against your text
AI diagram tools draw something plausible. This one keeps the receipts: each box carries the sentence it came from.
- Turn on Check and click a node — the editor jumps to the sentence it came from and highlights it. Nodes with no supporting sentence are drawn dashed.
- Ask for a change in one sentence — “split step 3 into two”, “only keep the key steps”, “make it a mind map” — and review the new diagram before it replaces the old one.
- Export Word or PDF and the diagram goes in as a picture, in the same font and colours as the text around it. Download PNG or SVG, or copy it as an image.
Where it gets hard
- Generating needs a free account
Pasting, editing and exporting need no account. The AI step does: sign in with a free account to generate or revise a diagram.
- It draws only from what you paste
The web editor works from the text in front of it. It does not search the web or read your other files.
- Complex diagrams may need a second pass
Diagrams are Mermaid underneath. A tangled process can come out busier than you want — one sentence of revision usually fixes it.
- Your text goes to the model when you click Generate
Otherwise the document stays in this browser. Clearing site data or switching browsers means it is not there — export what you want to keep.
Common questions
How does Auto choose?
By what the text is: ordered steps → flowchart, a hierarchy → mind map or org chart, groups of numbers → chart, dated tasks → Gantt, dated events → timeline, a problem and its causes → fishbone. The reason is shown under the diagram, next to a button to switch type.
Can I switch type afterwards?
Yes — Change type redraws the same content as another diagram.
Is it free?
