- Improved top bar action area with cleaner behavior for dense controls.
- Updated Transparent PNG export to remove full background regions (including enclosed white areas) for true transparent output.
February 2026
Feature Molecule Properties Panel
- New properties card in the 3D viewer showing compound name, IUPAC name, molecular mass, boiling point, and melting point.
- Properties are fetched automatically from PubChem when a structure is loaded or drawn.
February 2026
AI Gemini Chat Assistant
- AI chat assistant in the 3D viewer panel powered by Google Gemini.
- Ask about IUPAC names, molecular properties, or instruct the AI to draw/edit structures on the canvas.
- Removed legacy Crisp chat widget.
February 2026
Feature Accumulative PubChem Imports
- Importing a molecule from PubChem now adds it alongside existing structures on the 2D canvas instead of replacing them.
- 3D viewer also accumulates imported molecules.
February 2026
Feature IUPAC Name Lookup
- Added an IUPAC button in the toolbar to look up the IUPAC name of the drawn structure via PubChem.
February 2026
Feature JPEG Export
- Download 2D structures as JPEG from the toolbar.
- Export 3D viewer snapshots as JPEG.
February 2026
Feature Molecular Mass Display
- Shows the molecular mass of the selected molecule in the 3D viewer.
- Mass updates automatically when drawing or importing a new structure.
