About ContextDeck
ContextDeck converts PDFs, Office files, source code and entire folders into structured Markdown that AI tools can use. The application runs locally on Windows and supports 46 formats including PDF, DOCX, PPTX, Excel, Python, JavaScript, JSON and HTML. It performs local OCR for scanned PDFs in English and Spanish and can transcribe audio files or YouTube links to Markdown. The tool masks sensitive identifiers such as emails, credit cards, IBANs, phone numbers and ID numbers from 32 countries before any text leaves the machine. Users can add custom terms to a glossary for consistent masking across documents. After each conversion, ContextDeck provides a report showing what was hidden, allowing users to verify the output before sharing it with an AI assistant. The software emphasizes privacy by keeping files on the user’s computer unless explicitly exported.
