PDF.ai
PDF.ai works well for someone who reads long PDFs and wants quick answers and summaries, and for developers who need a simple REST call to turn PDFs into structured data. Users who only occasionally ask about a short file can stay on the free tier or use a general chatbot; enterprises with strict data-residency needs will find little public information about who runs the service.

- Chat with one file or across a whole library of uploads
- Separate parsing, extraction and splitting API with a free monthly allowance

- Annual billing cuts the Pro price from $17 to $10 a month
Cons
- Free plan is limited to very small files and page counts

- The site names no company, address or team
