The same numbers, a different view. Change the style in Design. Your values stay with you.
Paste a series over time — weeks, months, years — and the story writes itself from your numbers: the start, the peak, the turn, the streak and the change. Edit any step, then save the video. Everything runs in your browser, nothing is uploaded anywhere.
What is this chart story maker?
Meiku Charts' free story and video maker turns a series over time into a step-by-step story of your numbers, with every figure computed from the data and every sentence editable, and saves it as an MP4.
How to make a chart story
- Paste your data with time labels in the first column, or load a CSV file.
- Edit the story: highlight words, pick the points each step shows, change the big number.
- Pick where it will be shown (website, LinkedIn or Reels), watch the preview and download the MP4.
Is the video made on a server?
No. The MP4 is encoded in your browser with WebCodecs, so your data never leaves the page. A current Chrome or Edge is needed; the page says so when the browser cannot encode video.
Why does the free video have a mark?
Free videos carry a small Meiku Charts mark and close on a 2-second end card. Pro removes both, along with the marks on exported images and embedded charts.
What data makes a story?
One series over time with at least three values: weeks, months or years. The story finds the start, the peak, the turn, the streak and the change, and you can rewrite any of it.
Is this free and private?
Yes. This maker builds chart stories and their videos in your browser. Your chart data stays on your device, with no signup or maker usage limit. Free PNG and SVG exports carry a meikucharts.com mark; Free embeds keep the “Made with Meiku Charts” credit. Pro removes these marks and lets you choose your own credit line or no credit. Cloudflare Web Analytics measures anonymous page views, sets no cookies and never sees chart data. Pro license checks are explained in our Privacy policy.
How do I activate Pro?
Copy your Pro key from the Polar customer portal using your checkout email address, then enter it in your account and select “Activate Pro”. For clean exports in another browser, select “Use Pro in this browser”. Follow How to turn on Pro for websites, exports and the AI connector.
How do I embed the chart on my own page?
Click “Copy embed” to copy a script tag plus a <live-chart> element carrying
your current spec as JSON. Paste it into any HTML page and the chart renders live — no build
step required. The embed loads one hosted file from meikucharts.com.
Can I export the chart as an image?
Yes. “Download PNG” renders the current chart onto an offscreen canvas at 2x resolution and downloads it — useful for slides, docs, or anywhere embedding live HTML isn’t practical.
