ZyDoc — Custom ROI Calculator & Webflow Rebuild

The challenge.

ZyDoc's AI transcription service saves physician practices real money, but the old site undersold it — a dated WordPress build that looked like an off-the-shelf template. I migrated the site to Webflow and rebuilt it largely from scratch: modern, credible, and easy for their team to maintain. The logo only needed a light brush-up; the change people feel is the site and everything around it. The piece I'm proudest of, though, is the ROI calculator.

The ROI calculator.

Physicians buy on math, not promises. ZyDoc wanted a tool that made the savings concrete, and I designed and built an interactive calculator: choose your specialty or enter your own numbers, and it computes your annual ROI, revenue uplift, time saved per encounter, and how many additional patients a day that reclaimed time buys back — live, from your own practice's figures. Seven specialties come pre-loaded with real benchmark volumes, so a prospect sees a believable result before touching a single field. Then I added something the brief didn't ask for: a one-click branded PDF report. A champion inside the practice can forward it to whoever signs the check, or a ZyDoc rep can print it on the spot at a conference for a prospective practice. That extra is the part that landed well past what they expected.
"John, I cannot say how amazingly pleased I am with this calculator — it's incredible." — Matt Koerner, Board Advisor, Marketing, ZyDoc

Under the hood.

Designed in Webflow, with the logic in dependency-free vanilla JavaScript wired through a data-attribute contract — so ZyDoc's team can restyle the whole thing without touching code. I built it with an AI-assisted workflow: Claude and Codex for the calculation logic, Webflow's MCP for the build, across a versioned and tested iteration loop.
