ChatDiagram

ChatDiagram is an AI gantt chart maker tool. An AI flowchart generator from ChatDiagram that turns a written process description or pasted code into an editable diagram with standard symbols, branches, loops and start and end points, then exports it as SVG, PNG or PDF.

ChatDiagram's AI flowchart generator takes a written description of a process, an algorithm or a decision and returns a drawn diagram with start and end points, action steps, yes/no branches and loops already in place. Users type a paragraph into the editor, send it, and the tool lays out the chart using standard flowchart symbols: rounded terminals for the start and end, rectangles for steps, diamonds for decisions and parallelograms for input and output. Pasting code or pseudocode works the same way, with conditions and loops converted into branching decision paths. The workflow is conversational rather than canvas-first. Layout, spacing and arrow routing are handled automatically by a Sugiyama layered DAG with orthogonal routing, so no design skill is needed to produce something readable. Revisions happen by describing the change in words, for example asking for a recursive variant of the same algorithm, and each edit is stored as a version drawn from the previous one rather than retyped from scratch. When the drawing is right, text can be edited directly, nodes dragged into place, and the result exported as SVG, PNG or PDF at any size or kept as a share link. The audience splits roughly into three groups. Students use it to turn algorithms and programs into diagrams for assignments. Product and engineering teams map sign-up, login and error paths so every branch is visible in review. Operations and finance teams document approval chains and thresholds that need a single agreed version. Sample renders on the site cover binary search, two-factor login, purchase approval and employee onboarding, and a library of roughly 1200 flowchart templates offers a starting point when a blank description is hard to write. ChatDiagram also publishes neighbouring tools for narrower diagram types, including activity diagrams, CI/CD pipeline diagrams, control flow graphs, data flow diagrams, CONSORT diagrams and a dedicated code to flowchart converter. That makes the flowchart generator the general purpose entry point and those tools the specialists for software, clinical research and systems documentation. A free account is required and no card is asked for at sign-up.
