Read with Orbit, Understand faster.
Your AI companion for studying, researching papers, or reviewing reports. Ask anything, understand everything, learn faster.
Stop losing your AI answers.
You asked AI about a paper last week. Now you need that answer again — but where was that conversation? With Orbit, every AI conversation is saved with your file. Open your PDF, and everything is right where you left it.
Chat with your documents
Ask anything about your document and get instant, accurate answers from AI. Request summaries, clarify complex concepts, or find that section you vaguely remember. Create multiple conversation branches to explore different topics simultaneously without losing context. Whether it's a quick fact check or deep analysis, simply type your question and get the answer.
Instant translation with context
Select any text and get an instant translation to 10+ languages. Orbit delivers translations that make sense for your specific content, not just literal word replacements. No more copying text back and forth between translator apps. Just select, translate, and keep reading seamlessly. Translation is completely free on every plan. No credits are deducted.
Add images and text to your chat
Enhance your document conversations by attaching images or text directly in chat. Whether you want to share a figure, highlight a passage, or ask about a specific section, simply upload a photo or paste text. Every attachment is saved in your conversation history, so you can always go back and review exactly what you shared with AI.
Notes that remember where you left off
Take notes directly inside your documents. Write quick thoughts or link notes to specific text by dragging over it first. When you click a linked note in the panel, Orbit instantly jumps to that exact spot in your document, no more scrolling through pages to find your idea.
LaTeX math rendering
Academic papers are full of complex mathematical equations, and Orbit handles them beautifully. With native LaTeX support, AI responses render formulas, symbols, and expressions with perfect clarity. No more struggling to read garbled math notation. Whether it's calculus, linear algebra, statistics, or physics equations, Orbit displays them exactly, making content easy to understand.
Smart annotations
Highlight important passages and underline key terms with customizable colors. Take detailed notes directly on the page and organize your thoughts as you read. All your annotations are saved locally on your Mac and beautifully organized by document. Revisit your highlights and notes anytime.
PDF link preview
Orbit automatically detects links inside your PDFs and provides instant previews. No need to open a browser or switch apps, just click a link and see a summary, image, or webpage right inside the reader. Save time and stay focused.
