Top 20 e-signature software by AI search visibility (2026)

What we observed in this categoryauto-generated

DocuSign and Dropbox Sign both achieve perfect 100% visibility scores, yet the gap between them is stark: DocuSign holds a composite score of 77.5 versus Dropbox Sign's 70.0, primarily because DocuSign carries a 25% citation rate while Dropbox Sign has 0%. The category average visibility sits at just 22.5%, meaning both leaders appear in AI Overviews at roughly 4.5× the category norm. PandaDoc ranks second with 87.5% visibility and leads all brands on citation rate at 37.5%, giving it a composite score of 72.5 that challenges DocuSign's dominance despite lower raw visibility.

A notable divergence exists between being named and being trusted as a source. Dropbox Sign is mentioned in every AI Overview sampled yet is never cited as a reference link, suggesting AI treats it as a recognised brand noun rather than an authoritative source. GetAccept is the sharpest outlier: 0% visibility but a 25% citation rate, meaning AI actively links to its content to support answers about other brands without naming GetAccept itself in those responses. This named-versus-cited split is a structural pattern across the category, where the average citation rate is only 4.4% against 22.5% average visibility.

Reddit, PandaDoc's own domain, and TechRadar appear as the top three cited sources in AI Overviews for this category, ahead of brand domains like DocuSign and Adobe. This signals that AI Overviews are anchoring heavily on third-party review and community content rather than vendor pages when constructing citation links. YouTube and GetAccept's domain also appear in the cited source list, reinforcing that multimedia and niche competitor content is being surfaced. Adobe Acrobat Sign, despite its brand scale, achieves only 37.5% visibility and 0% citations, indicating AI does not treat category dominance as a proxy for content authority.
