Leafrune: A Private PDF Reader with On-Device AI

Leafrune is a fast and private PDF reader designed to run entirely on your own computer. It features an on-device AI assistant that allows you to interact with your documents in a completely new way. Simply open any PDF, and Leafrune will process its content in the background, making the AI assistant ready to answer your questions.

• Read and Ask: Open PDFs and ask questions in natural language. The AI assistant will provide answers directly from the document.
• Source Linking: Every answer is linked to the specific pages and sentences it comes from. Click a link to jump directly to the relevant passage, which will be highlighted for clarity.
• Complete Privacy: Your documents and data never leave your computer. Leafrune operates without requiring an account, has no cloud integration, and collects no telemetry.
• Form Filling: Fill in PDF forms, save your entries, and then ask the AI assistant about the information you've entered. Changes are saved directly into the PDF.
• Cross-Platform: Available for macOS (Apple silicon M1 or later) and Windows 10/11 (64-bit).
• Offline Functionality: After an initial one-time download of AI models (approximately 3.2 GB), Leafrune functions entirely offline.
• User-Friendly Interface: Features include a sidebar with a table of contents and page thumbnails, a powerful find function with highlighted results, and options for color inversion and theme selection (Light, Dark, or System).
• Printing Options: Offers a comprehensive print window with various settings for pages, layout, scaling, and preview.

Leafrune is free to use for personal and professional purposes.
