Introducing Ploti: Free Interactive Charts for Any AI Assistant
Ploti is a free, open-source MCP tool that renders 43 chart types as interactive widgets inside Claude, ChatGPT, Gemini, Cursor, and VS Code. No account required.

Charts have always lived outside AI conversations. You run an analysis, get a table of numbers, and then open a separate tool to visualize it. Ploti changes that. It is a free, open-source MCP server that renders 43 chart types as interactive widgets directly inside Claude, ChatGPT, Gemini, Cursor, VS Code, and Goose.
No account. No API key. One URL to connect. MIT licensed.
What Ploti does
When you connect Ploti to your AI assistant, you can ask it to make a chart the same way you ask it to write code or summarize a document. The chart appears inline in the conversation as an interactive widget: hover for tooltips, toggle legend items, switch between light and dark themes.
Ploti supports 43 chart types. The full list includes bar, grouped bar, stacked bar, horizontal bar, line, multi-line, area, stacked area, scatter, bubble, pie, donut, waterfall, candlestick, OHLC, heatmap, treemap, sunburst, sankey, radar, funnel, gauge, and more. The engine renders deterministic SVG output, meaning the same data produces the same chart every time.
Every chart carries a "Made with Ploti by Ooty" badge linking back to ooty.io/ploti. There is a copy-embed button that outputs an <iframe> snippet for embedding charts in blog posts, Substack issues, or any HTML page. There is also a PNG fallback for contexts that do not support interactive rendering.
How to connect
The connection process is the same as connecting any MCP server. No credentials needed.
