Features

[FEATURES]

Connects to your agent

Claude Code, Codex, Cursor, Claude Desktop and Antigravity connect to Hub locally. Ask any of them for a waterfall or a mekko and Hub builds it.

Straight into your deck

With PowerPoint or Google Slides open, the chart is sent there as you prompt. It arrives as a native Chartbuddy chart, not a pasted image.

Edit where it lands

Charts stay editable on the slide in the PowerPoint and Google Slides editors. Anyone on your team with Chartbuddy installed can reopen and change them.

Desktop editor

A native app for Mac and Windows. Build a chart by hand when you are not working in a deck, or open one that is already made.

Control every detail

Axes, axis breaks, number and date formats, legends, data labels, annotations, call-outs and smart arrows for growth and CAGR. Point and click, no code.

Full business library

All 14 chart types, including waterfall, mekko, bar mekko and marimekko. The same library as the deck editors and Embed.

[HOW IT WORKS]

How it works

  1. 01

    Connect your agent

    Install Hub, then point Claude Code, Codex, Cursor, Claude Desktop or Antigravity at it. The connection is local, so your numbers stay on the machine.

  2. 02

    Open your deck

    Have PowerPoint or Google Slides open on the slide you want the chart on. Hub sends it to whichever deck surface you are working in.

  3. 03

    Prompt the chart

    Ask your agent for the chart in the language you already use with it. It appears on the slide, editable, with the data behind it. Hub has no prompt box.

  4. 04

    Edit it in the deck

    Change it on the slide with the PowerPoint or Google Slides editor. The data stays attached, so next month you reopen it and update the numbers.
