Main capabilities:
- AI chat with documents, supporting simultaneous search across multiple documents and online chat without downloading.
- Supports multiple file types: PDF, DOC, PPT, TXT, Markdown; CSV, XLS, and EPUB are marked as coming soon.
- Each answer provides source citations for easy verification against the original text.
- Supports exporting conversation content.
- Supports more than 40 languages (the FAQ mentions more than 20, including English, German, Romanian, Spanish, Portuguese, French, Italian, Dutch, etc.).
- Uses Stripe to process payments, uses encryption protocols to protect uploaded documents, and hosts servers in secure data centers.
