Most tools for sharing work with an NDA step are priced per seat for teams. SignToSee is built for one person. Every link carries your name, and every open is confirmed with a one-time code sent to their inbox, even on the free plan. Your work is grouped per client. When a piece needs it, the client accepts your NDA before the file opens, and both sides get the signed PDF. Files are encrypted in your browser and hosted in the EU. Branding from €4.99/mo, NDA from €14.99/m, billed yearly. EU only.
