I built a DocSend competitor in weeks using Claude Code

I Built a DocSend Competitor in Weeks Using Claude Code — Here's the API I've been working nights and weekends accelerating ideas to production using AI-assisted development. CloakShare is the first one I'm shipping publicly. The problem I kept running into: I needed to share documents and videos securely — with watermarks, access tracking, and expiry — without paying $50/seat for DocSend or spending weeks building a viewer from scratch. So I built the API I wished existed. What CloakShare Does One API call secures any document or video: curl -X POST https://api.cloakshare.dev/v1/links \ -H "Authorization: Bearer YOUR_API_KEY" \ -F file = @proposal.pdf \ -F expires_in = "72h" \ -F watermark = true \ -F require_email = true You get back a secure URL. Recipients hit an email gate, see a watermarked viewer, and can't download the file. You see exactly who viewed it, which pages they read, and for how long. That's it. No viewer to build. No infrastructure to manage. What It Supports PDFs,
