Actual results may differ materially, and we disclaim any obligation to update any forward-looking statements or outlook. A historical reconciliation to comparable GAAP metrics can be found in today's earnings release. Today, I will cover four things: our financials, AI study results, usage growth, and commercial AI progress. Respectively, these were both beats of 3% and 8% versus the high end of our guidance.
We are proving you can still post best-in-class software margins while investing heavily in clinical AI. To that end, I am proud to report that we are seeing record AI usage while topping the first large-scale independent head-to-head trial of clinical AI vendors. Quarterly active workflow prescribers grew more than 30% year-on-year to record highs, with nearly half using our AI tools in Q1. AI prompt volume was up more than 25% quarter-on-quarter, while our AI Scribe note-taking users grew a whopping 10x this July over prior.
New Search contracts are driving our revenue raise for the year, and we are just getting started. With that, I'll hand it over to our CFO, Matt Sonefeldt, to walk through our financials and guidance. Q1 2027 was a strong quarter for Doximity, with robust revenue growth. Turning to our top line, Q1 2027 revenue of $157 million outperformed the high end of our guidance, with growth improving to 7% year-over-year.
