Chart to CSV
Paste a chart screenshot, get the underlying data back as CSV — with the extraction re-rendered beside the original so you can verify it at a glance.
Chart to CSV is the studio's clearest machine-built artefact: in a single evening — 9 May 2026 — the agent pipeline registered the domain, committed the full MVP, and completed the first production deploy. Repo init to live was under two hours.
The flow: drop or paste a chart screenshot, and a Cloudflare Worker sends it to a vision model constrained by a strict JSON schema — chart type, axes, series. The extracted data is re-rendered as a clean chart beside the original for at-a-glance verification, then downloads as a CSV that opens correctly in Excel. Seven chart types are handled: line, bar, stacked bar, scatter, area, pie and error-bar.
The product measures itself in public: a 27-fixture synthetic harness — generated charts with known data — scores the extractor at 88.9% and re-runs on a weekly schedule, with results published on the site's accuracy page. The number on the marketing page is the number the tests produce.
Four days after first deploy it was repositioned for launch: price cut from $19 to $7 a month, three persona landing pages added, and the public launch logged on 13 May 2026. It runs on Cloudflare Pages with a Worker API, Stripe subscriptions and passwordless sign-in.
