Questions people ask.

What is the best e-signature software according to AI?

DocuSign holds the consensus #1 at the latest close with a score of 50 out of 100, ahead of Adobe Acrobat Sign. The models don't fully agree: 1 different brand is crowned #1 across the four models.

ChatGPT's current #1 for e-signature software is shown in the model column of the full ranking.

Which e-signature software does Claude recommend first?

Claude's current #1 for e-signature software is shown in the model column of the full ranking.

How are these rankings measured?

We ask each model the same buying questions on every run (1,610 queries this period), record the full answers, and score each named brand 0-100 by how early and how consistently it appears. Every question runs through the official model APIs, with web search on, not through the consumer chat apps, so nothing is personalized to a user. Each model is scored independently; the consensus blends all 4.

Do the AI models agree with each other?

At the top, yes. Every model crowns the same #1 at the latest close. Further down the board they diverge, which is why each brand carries a spread figure: the gap between its best and worst model rank.

This is the guide. The record has more.
