Upload PDFs, Office documents, images and code, then ask the app to summarise, explain or extract what you need.
Store documents locally so Chatbox can recall and answer from your own materials while your data stays on your machine.
Pull current results from the web and display answers with Markdown, Mermaid diagrams, LaTeX formulas and code previews.

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.
