Komodo PDF is a free, GPLv3 open-source PDF reader for Windows, macOS, and Linux. Its local-first reader supports continuous scrolling, zoom, fit-width and fit-page views, document outlines, and text selection. An AI panel answers questions using passages indexed in a local vector store. Clicking a citation takes you to the cited passage and highlights it, while a per-page badge marks pages without a text layer, such as scanned images. If the document cannot answer, the assistant can use general knowledge and indicate that fallback. Chat works with OpenAI-compatible providers using your own API key and with local chat endpoints. The maker says Komodo has no backend, sends no telemetry, and does not upload documents to Komodo; remote chat sends retrieved passages to the configured provider. With local ONNX embeddings and a local chat endpoint, documents are said to remain on the laptop. API keys use the operating-system keyring with an encrypted disk fallback. Windows downloads include EXE, MSI, and portable ZIP files, with published SHA-256 checksums. Version 0.1.1 is displayed.
