Electronic signatures and agreement workflows built into Dropbox
Recipients can review and sign agreements securely without creating an account, which removes friction from external signing.
Prepare NDAs, offer letters and contracts once, then reuse them for future requests to save time on recurring paperwork.
Embed secure, branded eSignature flows directly into your website, app or customer experience with a dedicated API.
Completed agreements are saved automatically to your preferred storage account so nothing gets lost in inboxes.

Give your coding agent real design judgment
A structured skill set that agents load to make typographic, layout, spacing, and color decisions with design intent rather than defaults.
Identifies recurring AI-generated UI clichés such as chip overload, card-in-card nesting, weak hierarchy, and vague calls to action.
Helps the agent stay consistent with the tokens, components, and conventions of your existing design system.
Bakes in contrast, focus, semantic structure, and responsive behavior so built interfaces hold up across devices and audiences.
