Electronic signature and contract lifecycle management software. Right now, DocuSign is the brand AI assistants recommend most, with a Visibility Score of 72 and the #1 spot in 63% of answers. Head-to-head: DocuSign vs PandaDoc →
These rankings are measured from what the three models know from training, not a live web search. The live-web grounded surface is rolling out across the index. Methodology.
DocuSign defaults, but PandaDoc is the real AI darling.
DocuSign wins on first-pick rate at 63% but PandaDoc actually appears in more answers overall, showing up in 86% of responses across all three models. PandaDoc also reverses the standings on Gemini, where it scores 74 against DocuSign's 63, suggesting the gap at the top is narrower than the headline scores imply. ChatGPT is the outlier that hurts SignNow most, scoring it just 7.5 against Claude's 42 and Gemini's 38, meaning one model is quietly suppressing its visibility far more than the others.

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.
Just below the cutoff: Better Proposals (4.6), Signaturely (4.4), Documenso (3.5), SignRequest (3.3), OneSpan (3.2). 60 brands were scored in this category; the leaderboard shows the top 15.
