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.
Build and share random generators for free with lists and simple code
Define items as lists and let Perchance pick randomly, producing names, items, prompts or full paragraphs.
Customize how your generator looks and behaves with standard web markup, styling and scripts.
Publish generators instantly so anyone can open and use them from a shareable page.
Browse and reuse generators created by the community, from RPG tools to story prompts and AI apps.
