1. Open a chat
Start a new conversation and select a model with enough context for your file size.
2. Attach your PDF
Use the attachment control to pick a PDF from your device. See document features for supported formats.
3. Ask clear questions
- "Summarise this in five bullet points"
- "What are the payment terms in section 4?"
- "Extract all dates and amounts into a table"
- "Compare this PDF to [another attached file]"
4. Combine with research
For topics that need live data, pair file context with web search or run a broader Deep Research task separately.

Common questions
- How large a PDF can I use?
- Limits depend on the model context window and device memory. Use models with larger context for big files, or split documents into sections.
- Can I summarise a PDF quickly?
- Yes. Attach the file and ask for a summary, outline, or key takeaways. Pick a fast model for drafts, a stronger one for nuance.
