# Linkjar > Linkjar is the smart way to send sales and marketing materials: share decks, proposals, brochures, videos and web pages (including pages built with Claude, ChatGPT or Gemini) as links on your own brand, see who opened them and what they read, and control who can access them. Key facts: - Formats: PDF, PowerPoint, Word, Excel (converted to PDF), HTML pages and zipped sites, video, Canva designs (via the Canva app). - Tracking: who opened each link, time per page, scroll depth and clicks on web pages, watch time on video, forwards; alerts by email and Slack. - Access control: per-person links, email gate (optionally limited to one company's domain), passwords, expiry dates, rooms (several documents behind one link). - Branding: custom domains, logo and colours on every viewer, call-to-action button. - Claude connector (MCP): publish pages, create per-person links and ask who viewed a document from inside Claude. Connector URL: https://linkjar.com/mcp - CLI for agents and scripts: `npx linkjar login`, then `npx linkjar send deck.pdf` (PDF, HTML, a folder with index.html, Word/PowerPoint/Excel) and `npx linkjar activity `.
