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—always free, with no limits or hidden costs. 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.

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.
