Chat With PDF
Chat with PDF, directly on your Mac
Orbit lets you ask questions about a PDF while the file stays open in the same workspace. That means less tab switching, easier follow-up questions, and conversation history that still makes sense when you come back to the same document later.
Ask follow-up questions without re-explaining the document.
Keep saved conversations attached to the same PDF file.
Add text snippets or images when a question needs extra context.
What makes Orbit better than pasting a PDF into chat
Follow-up questions stay grounded
Instead of starting from scratch each time, Orbit keeps the conversation near the PDF so your second and third questions remain tied to the same reading session.
Saved conversation history
Each file keeps its own conversation trail, which is useful when you reopen a report or paper and need to remember what you already asked.
Attachments for better questions
If a figure, table, or external snippet matters, you can add images or text directly in chat to make the prompt more precise.
Useful answers stay in your workflow
Useful AI answers do not have to disappear inside a generic chat log. Orbit keeps them close to the document so they can feed later review and note-taking.
Where this is especially useful
- Ask a report for the key takeaway behind a chart or appendix.
- Clarify unfamiliar terms in a technical PDF without leaving the document.
- Compare sections of a paper by asking follow-up questions against the same source.
- Keep a file-specific Q&A archive for later review.
Orbit for macOS
Keep the reading workflow in one place
Orbit combines PDF viewing, document-aware AI chat, translation, highlights, and notes in a single macOS workflow. Instead of bouncing between a reader, a browser, and an AI tab, you stay inside the same document.
Common questions
Is this just generic chat pasted next to a PDF?
No. Orbit keeps the PDF open, conversation history attached to the file, and related reading tools such as translation and annotations in the same app.
Can I reuse previous conversations?
Yes. Orbit stores prior chat context with the document, so reopening the same PDF gives you the earlier conversation trail instead of a blank slate.
When is chat with PDF better than a summary tool?
When you need iterative reading. A summary helps once, but document chat is better when questions change as you inspect more pages, tables, or evidence inside the PDF.
