Guide

Chartr.ai is an AI-powered charting engine. Give it a prompt, a webpage, a PDF, a YouTube video, or an image - and it turns that into interactive, shareable charts.

How it works

Prompt - provide text, paste a URL, upload a file, or combine
AI generates charts - our AI agent uses tools at its disposal to generate chart specs
Render the charts - the engine renders the charts
View, edit, share - interact with charts on a board, download images, or embed them

You can use Chartr.ai through the web app, the REST API, or via MCP from AI tools like Claude and ChatGPT.

Chart types

Chartr.ai supports a range of chart types across two categories.

Process & structure

Type	What it does
Flowchart	Visualize processes and decisions
Sankey Diagram	Show flows and resource distribution
Sequence Diagram	Map interactions between entities
State Diagram	Model states and transitions
Timeline	Show events chronologically
2x2 Matrix	Compare across two dimensions
Mind Map	Organize ideas hierarchically

Data & numbers

Type	What it does
Bar Chart	Compare values side by side
Treemap	Show proportions as nested rectangles
Pie Chart	Show proportions of a whole
Table	Structure data in rows and columns

The AI selects the best chart type for your input automatically, but you can always request a specific type.

A board is a collection of one or more charts generated from a single prompt. Boards can be viewed, shared via link, and embedded. Each chart on a board is interactive - click elements to reference them in follow-up messages.

Chartrs

Chartrs are custom charting presets with their own instructions and behavior. Think of them as specialized versions of the engine tuned for a specific use case - like a "competitor analysis" chartr or a "project timeline" chartr.
