What's the best ChatGPT app for signing documents (e-signatures)?
Doc-checked .
Adobe Acrobat, for signing a PDF or sending one for signature — its ChatGPT app handles signature workflows and is free for all ChatGPT users globally. For high-volume, audit-tracked agreements, DocuSign is the dedicated platform, but it needs a paid plan and its ChatGPT connector is newer and not yet hands-on verified.
Why this is the pick
For most people signing or sending a single PDF, Adobe Acrobat is the accessible pick: it handles signature workflows in the ChatGPT conversation and is free for all ChatGPT users globally since December 2025. DocuSign is the category leader for enterprise agreement management — envelope status, template sending, audit trails — but it requires a paid plan and its ChatGPT connector is newer, so we list it Needs verification pending a hands-on test.
