In their own words
Apdf
Apdf generates and tracks PDFs through an API, sending reader activity to apps or AI agents. PDF operations include HTML-to-PDF generation, merging, splitting, compression, watermarking, OCR, and password security. Reader analytics report opens, page reads, time spent, downloads, prints, and other events. Tokenized recipient links associate activity with named readers and can be deactivated or revoked. Recipients use a hosted browser viewer without installing an app or plugin; they can annotate PDFs and submit form fields, with captured information delivered as structured data. Event-based automations send webhooks to external endpoints. The site describes MCP connections for Claude, ChatGPT, Cursor, and Gemini, alongside webhook examples involving Slack, HubSpot, Pipedrive, and S3. Apdf says data is hosted in the EU, encrypted in transit and at rest, and handled in a GDPR-compliant manner. The free Hobby plan includes 3 tracked documents and 500 PDF operations per month. Pro costs $39 a month, billed $39 / mo; Business costs $149 a month, billed $149 / mo.
