Prism MD is the markdown reader built for the age of AI. Open any document from ChatGPT, Claude, Gemini, or your own notes and read it the way it was meant to be read — with proper typography, syntax-highlighted code in 190+ languages, rendered math via KaTeX, and live Mermaid diagrams.
KEY FEATURES
• Pure reader, lightning fast — open a 100-page document and it just works
• Syntax highlighting for every major language (JavaScript, Python, Rust, Go, SQL, and more)
• LaTeX math rendering with KaTeX
• Mermaid diagrams (flowcharts, sequences, state machines) drawn live
• Dark mode tuned for long reading sessions
• Offline support — documents you've opened stay available without a connection
• Import markdown from any AI tool: ChatGPT export, Claude chats, Gemini responses
• Edit, split view, or read-only modes
• Share your documents with a clean link, a QR code, or export to HTML / PDF
• Structured data extraction — automatically pull action items, decisions, and key points out of any doc
• Multi-model comparison — run the same document through GPT, Claude, and Gemini and diff the output side by side
• Diff view for tracking changes over time
• End-to-end private: your documents stay on your device by default
BUILT FOR THE WAY AI WRITES
Most markdown apps were built for software documentation. Prism MD was built after looking at thousands of AI-generated documents and asking: what would make these delightful to read? Warm typography, generous whitespace, code that breathes.
