A data story · made with ContentRoof

A chart that comes with its own story

Chart tools give you a chart. A good data video needs more: someone to say what changed, why it matters and what to look at. The Data story writer mode does both. Paste your numbers with a sentence about them, and the AI builds a short video around them:

The AI is told to use your numbers exactly and never to invent ones that aren't in your data, so the chart shows what you pasted.

Who it's for

Write a chart scene yourself

In the script, a chart is a single line. Each entry is a label and a number, separated by semicolons:

# chart: Jan 120; Feb 180; Mar 260; Apr 410 | label: Newsletter subscribers | style: line
In four months the newsletter went from 120 readers to 410, and April alone added 150.

Charts also appear without a chart line. When a sentence describes growth or decline ("sales doubled", "the population fell"), a rising or falling chart is drawn automatically, with the subject riding the tip of the line.

Bars or a line?

Your data Use Example
Change over time Line Monthly visitors, yearly temperature
Comparing a few things Bars Sales by city, votes by party
One big number A counter "86 billion neurons"
Before and after Two bars, or a two-sided comparison Price in 2015 vs today

What makes a chart video easy to follow

One honest limit: each chart scene shows one chart for that scene. It is not a tool for racing bars over dozens of time steps.

Questions

Will the AI change my numbers?

No. The Data story mode is instructed to use your numbers exactly and never to invent numbers that aren't in your data. You can check every value in the script before you download.

Can I paste data from a spreadsheet?

Yes. Paste the labels and values as text. In the script, each chart is one line of label and value pairs separated by semicolons.

What kinds of charts can it make?

Bar charts to compare things and line charts for change over time, plus counters for single big numbers and automatic rising or falling charts when the narration describes growth or decline.

Can I make a 16:9 chart video for a presentation?

Yes. Choose 16:9 and the narration sits on the left with the chart on the right.

Does it work in other languages?

Yes, in all 9 supported languages. The narration and captions use your chosen language.
