Connect a live data source, set a schedule, and every embed and export stays current on its own.
When the underlying data moves, most charts do not. Someone has to notice, pull the new numbers, re-export the image, re-upload it, and swap the embed — every reporting cycle, for every chart. One well-known macro writer reckons charts are 80 per cent of the effort behind a post, and advisers and research desks rebuild the same handful of exhibits week after week. The result is predictable: a chart ships looking sharp, then quietly goes stale the moment the next print lands, and nobody wants to be the one who published last month's figure as if it were today's.
Quadesto breaks that cycle by making the chart itself live. You connect a real data provider, tell Quadesto how often to re-fetch — hourly, daily or weekly — and it does the rest. On every scheduled run it pulls the latest numbers, recomputes, and refreshes everything downstream: the interactive embed in your newsletter keeps the same URL but shows the current figure, and your high-res exports regenerate against fresh data. You set it up once and the newsletter, report or dashboard stays accurate without you touching it again.
Pick a provider, choose a schedule, and publish. From then on Quadesto re-fetches on the cadence you set and updates the chart in place. Because the embed URL never changes, you do not re-paste anything into Ghost, Beehiiv, WordPress, Notion or Webflow — the page your readers already have simply shows newer numbers next time they load it. The maintenance task you used to do every cycle disappears entirely.
Auto-refresh works against real sources, not a one-off upload. Quadesto connects to fifteen providers including FRED, Alpha Vantage, Polygon, Databento, the US Treasury and CoinGecko, and it will call a custom REST API when your data lives somewhere else. Credentials go into an encrypted vault and are used server-side, so your keys never reach the browser or sit inside an embed. Each scheduled pull hits the provider directly, so the figure on the chart is the figure at the source.
Auto-refresh is only useful if you trust what it fetches. In Quadesto the AI assembles the chart, but a deterministic engine of more than ninety functions computes every value — so a year-on-year change, a moving average or a spread is a defined calculation you can trace back to the source rather than a guess. When the schedule brings in new data, those same calculations re-run exactly, giving you a figure you can defend to a compliance officer or a sceptical reader. Fresh and correct are not a trade-off here.
A refreshed chart is only valuable where your audience sees it. The live interactive embed is the piece that stays current on the web, updating silently on its schedule for everyone who views it. You can also pull high-resolution PNG, SVG and PDF exports whenever you need a fixed asset for a deck or a printed report, generated from the latest data at the moment you export. Link unfurls for Substack and email give you a clean preview card that points back to the always-current chart.
We will be straight with you about one limit. An image baked into an email is a snapshot taken at send time — once it lands in an inbox it cannot change, because that is how email works, not a shortcoming you can configure away. The live embed on your website or newsletter page is the thing that keeps updating, and it is where auto-refresh earns its keep. Use the embed for anything that needs to stay current, and treat an emailed image as the figure as of the moment you pressed send.
Connect a live source, set your schedule, and let every embed and export refresh itself on its own. Start free, then unlock auto-refresh on Creator at £39 or Pro at £149 — no per-seat pricing, and numbers you can check against the source.
