Electronic health record and practice management systems for physician offices and clinics. Right now, athenahealth is the brand AI assistants recommend most, with a Visibility Score of 69 and the #1 spot in 49% of answers. Head-to-head: athenahealth vs eClinicalWorks →

These rankings are measured from what the three models know from training, not a live web search. When the models DO search the web, see which sources they cite. Methodology.

athenahealth dominates; everyone else is fighting for relevance.

athenahealth leads #2 eClinicalWorks by 37 points and wins the first-pick slot in 49% of answers, a gap that makes the rest of the field look like a footnote. The three models largely agree on athenahealth's primacy, though Gemini nearly ignores eClinicalWorks while handing Elation Health a 67 model score that no other model comes close to matching. Below athenahealth, scores cluster between 29 and 33, meaning positions 2 through 5 are essentially tied and none has found a way to break out.

The ± under each score is the reliability band: how much the number would move if we re-ran the identical measurement. It is tight because each prompt is sampled multiple times. It is not the same as how much the ranking depends on which prompts we ask — a separate, wider figure shown on hover.
