AI PDF Reader
AI PDF Reader for macOS
Orbit gives you one place to read PDFs, ask follow-up questions, translate difficult passages, and keep notes attached to the same file. It is built for people who spend real time inside reports, papers, manuals, and other long-form documents.
Ask questions without leaving the document you are reading.
Translate passages with context-aware AI inside the reader.
Keep highlights, notes, and saved answers attached to each PDF.
Why Orbit works well for PDF-heavy workflows
Document-aware chat
Ask Orbit about reports, manuals, contracts, or papers and continue the conversation while the source PDF stays open in front of you.
Contextual translation
Select text and translate it in context, which is especially useful for technical writing, research papers, and multilingual documents.
Notes and annotations in place
Capture highlights, linked notes, and page-level context without losing your place in the document.
macOS-native workflow
Orbit is designed around a desktop reading workflow, so reviewing and revisiting PDFs feels closer to a focused Mac app than a stack of browser tabs.
Where this is especially useful
- Review long business reports and pull out the important numbers faster.
- Read research PDFs and ask follow-up questions while checking the original source text.
- Translate sections of foreign-language documents without copy-pasting into another app.
- Keep a running set of document-specific notes you can revisit later.
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 Orbit only for academic PDFs?
No. It also fits reports, technical docs, proposals, policy documents, manuals, and other PDFs where you need both reading and follow-up questions.
Why use a dedicated AI PDF reader instead of a chat tab?
A dedicated reader keeps the source PDF, AI responses, notes, and annotations in the same place, which is easier to revisit than scattering context across browser tabs.
Does Orbit work as a normal PDF reader too?
Yes. You can still browse pages, highlight text, annotate passages, and read PDFs normally, with AI features layered on top when you need them.
