AI PDF Q&A: Ask Questions About Your Documents
Key Points
- Ask specific questions about your PDF and get targeted answers with context
- AI references the document content directly, providing relevant excerpts in its responses
- Much faster than searching through a long document manually
Instead of searching through a lengthy PDF to find specific information, AI Q&A lets you ask natural language questions and get precise answers. Upload your document, ask your question, and the AI finds and presents the relevant information along with context from the source material.

Questions you can ask per document
Common Use Cases
Contract Clause Lookup
Ask 'What is the termination clause?' or 'What are the payment terms?' to instantly find specific provisions in lengthy contracts.
Technical Documentation Search
Query API documentation or technical manuals with questions like 'How do I configure the database connection?' for targeted answers.
Research Data Extraction
Ask 'What was the sample size?' or 'What were the main findings?' to extract specific data points from research papers.
Policy & Compliance Queries
Quickly find answers to compliance questions in policy documents, employee handbooks, or regulatory guidelines.
Q&A Tips
Ask specific questions for the best results—'What is the refund policy?' works better than 'Tell me about policies.'
Follow up with related questions to explore a topic in depth within the same document.
For complex documents, break your questions into smaller, focused parts.
Always verify AI answers against the source document for critical decisions—AI can occasionally misinterpret context.
PDF text is extracted in your browser and sent to the AI API for question answering. The original file is not uploaded. AI responses are based on document content but may not always be perfectly accurate—verify important information in the source document.
