Chemtrails

Chemtrails is a lightweight, zero-overhead Obsidian plugin that renders SMILES (Simplified Molecular Input Line Entry System) chemical notations into crisp, responsive vector SVG diagrams natively within your notes.

The plugin acts as a bridge from 'smilesDrawer' of the reymond-group to Obsidian.

Please read their original paper published by the Journal of Chemical Information and Modeling: 10.1021/acs.jcim.7b00425

For a full documentation on how your molecules get drawn, read their README.md.

Features

  • Native SVG Rendering: Renders vector paths directly inside your notes using smiles—no external image generation servers or APIs required.
  • Dynamic ViewBox Framework: Automatically crops empty whitespace around molecules. Small molecules (like Methane) remain naturally small, while large structures (like Caffeine) scale down smoothly to fit your active pane width.
  • Obsidian Theme Integration: Integrates cleanly with default light and dark themes using secondary background color matching.

Usage

Simply wrap any standard SMILES string inside a smiles Markdown code block:

```smiles
CN1C=NC2=C1C(=O)N(C(=O)N2C)C
```
