Apdf
What it is
Apdf generates and tracks PDFs through an API, with reader activity streamed to apps or AI agents. Its document operations include HTML-to-PDF generation, merging, splitting, compression, watermarking, OCR, and password security. Reader analytics can report opens, page reads, time spent, downloads, prints, and other events. Tokenized links associate activity with named recipients and can be deactivated or revoked. Recipients use a hosted browser viewer without installing an app or plugin, where they can annotate PDFs and submit form fields; captured information is delivered as structured data. Event-driven automations can send webhooks to external endpoints. Apdf describes MCP connections for Claude, ChatGPT, Cursor, and Gemini, with webhook action examples involving Slack, HubSpot, Pipedrive, and S3. The company 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. API documentation lists a 100 MB upload limit, request limits, and 60-minute storage for generated PDFs.
