Writing chemistry notes in standard word processors is a nightmare. General markdown editors lack deep chemistry support out of the box.
MarkChem is a specialized, open-source desktop editor that combines the speed of Markdown with deep integrations for chemical equations, molecular drawing, and AI assistance.
- ⚛️ Native Chemistry Syntax: Write chemical equations natively using
mhchem(\ce{H2O}). - 🧬 Molecular Drawing (JSME): Draw 2D molecules via the built-in UI and insert them instantly as SMILES syntax. No external tools needed!
- 📊 Periodic Table Integration: Access an interactive periodic table to quickly lookup and insert atomic properties into your notes.
- 🤖 Chem AI Assistant: A built-in AI assistant powered by Google Gemini (BYOK). Select a chemical reaction and ask the AI to balance it, explain it, or brainstorm synthesis pathways.
- ⚡ Lightning Fast: Built on Tauri and Rust. Uses a fraction of the RAM compared to Electron apps like MarkText or Obsidian.
- Markdown First: Write seamlessly in Markdown with real-time, live preview.
- Offline & Secure: Runs entirely on your local machine with zero telemetry.
- Export Anywhere: Export your notes directly to .md, Word (.docx), or PDF.
