AI Flowchart Maker

Describe it.
Watch it draw itself.

Drop in a PDF or say what the process is, and a real editable diagram appears. Eight diagram types, twenty-nine node types, and a canvas your whole team can be on at once.

Every node here is editable. Drag it, relabel it, branch off it.

Start from anything

You bring the mess. It brings the diagram.

Most flowchart tools start you at a blank canvas and a shape palette. This one starts from whatever you already have.

A PDF

Upload the runbook nobody has updated since 2019 and get the process it describes, as a diagram.

A deck or an image

PowerPoint files and screenshots work too. The structure gets read, not just the words.

A sentence

Describe the process in plain language. No shape vocabulary, no connector syntax.

A note you already wrote

Turn any document in your workspace into a chart without leaving it.

Every diagram type

Not just flowcharts.

Ask for a fishbone and you get a fishbone: spine, bones, causes, laid out correctly. Not a flowchart wearing a different label, and not a pile of rectangles you are left to arrange yourself.

Decision nodes carry real branch labels — Yes, No, or your own wording — and four auto-layouts reflow the whole chart without touching a single box.

Specialised intelligence

It knows what it is drawing.

A shape library treats every diagram as boxes and lines, then leaves the thinking to you. These types are modelled properly, so what comes back behaves like the thing it claims to be.

Four types get their own reasoning pass

Gantt charts, mind maps, fishbone diagrams and SWOT grids each route to a dedicated path with its own depth, instead of one generic prompt trying to cover every diagram ever invented.

Two arrive as a single object

A SWOT grid and a fishbone come back as one composite node, not a pile of shapes. Resize it and the contents reflow. Add a cause category and the bones redistribute themselves.

Dependencies are real data

A Gantt bar knows which task it is waiting on, in all four relationship types. Move one and the chain responds, rather than quietly going out of date.

Auto-layout

Stop dragging boxes into rows.

One click rearranges the whole diagram. The nodes and their connections stay exactly as you built them, they just stop overlapping.

On the canvas

It generates the diagram. You still own it.

Nothing here is a rendered picture you have to regenerate to change. Every node is a real object you can drag, restyle, annotate, and connect.

Twenty-nine node types, including

Branches that say what they mean

Label a path Yes, No, Approved, or anything else. Complex logic stays readable.

Styling that carries your brand

Color-code nodes, swap fonts, pick a theme, and use rich text inside labels.

Data tables on a node

Attach a structured table to any box for specs, owners, or SLAs.

Comments on the box in question

Threaded comments anchor to the node they are about, not the bottom of a doc.

Everyone at once

Live cursors, presence, and node locking so two people cannot fight over one box.

Thirty-nine templates to start from

Org charts, user flows, decision trees, SWOT, data flows, network diagrams.

Questions

Flowchart questions, answered.

Can I really make a flowchart from a PDF?
Yes. Upload a PDF and Theo reads the processes, decisions, and connections out of it, then builds a fully editable diagram. It works with PowerPoint files and images too. The result is real nodes and edges you can drag and relabel, not a picture of a chart.
What kinds of diagrams can I make?
Flowcharts, mind maps, org charts, ER diagrams, sequence diagrams, SWOT grids, Gantt charts, and fishbone diagrams, plus swimlanes, decision trees, data flows, and network topologies. There are twenty-nine node types and thirty-nine ready-made templates to start from.
Is the AI flowchart generator free?
Yes. The free plan includes AI generation, the full editor, real-time collaboration, and export, with no card required. Paid plans raise the limits and add more AI credits.
Can several of us edit the same diagram at once?
Yes. Multiple people can work on one flowchart simultaneously with live cursors, presence indicators, and node locking so two people cannot edit the same box at the same moment. Comments thread on the specific node they are about.
What can I export?
PNG, SVG, PDF, PowerPoint, Word, Excel, and JSON. You can also share a public link that opens without a signup, so a reviewer can look at the diagram without making an account.
Do I have to know which shape means what?
No. Describe the process in plain language and the right node types get chosen for you: rounded terminals for start and end, rectangles for steps, diamonds for decisions, parallelograms for inputs and outputs. You can change any of them afterwards.
What does auto-layout actually do?
It repositions every node so nothing overlaps and the connections read cleanly, without changing your structure. There are four options: top to bottom, left to right, radial, and force directed. It is the fastest way to clean up a diagram that grew messy.
