MolSketchGo

Draw, explore, and share molecular structures on the go. Now with 3D viewing, PubChem search, and SMILES/MOL/SDF import & export.

MolSketchGo is a mobile molecular structure editor designed for chemistry students, educators, and researchers. Sketch 2D chemical structures with an intuitive touch-based editor, then instantly convert them to interactive 3D models.

KEY FEATURES • Intuitive 2D Editor — Draw atoms and bonds with simple tap and drag gestures. Supports single, double, triple, wedge, and dash bonds. • Element Palette — Quickly switch between C, N, O, S, P, F, Cl, Br, I, B, and H. • Ring Templates — Place benzene, cyclohexane, and cyclopentane rings with one tap. • 3D Viewer — Convert your 2D sketches into rotatable, zoomable 3D models with ball-and-stick, space-filling, and stick representations. • PubChem Integration — Search compounds by name, CID, or SMILES. View compound data including molecular formula, weight, exact mass, IUPAC name, and synonyms. Load 2D structures or view 3D conformers directly from PubChem. • Import & Export — Import and export SMILES strings, MOL files, and SDF files. Export structures as PNG images or SVG vectors. Generate IUPAC names via PubChem. • Molecule Info — View molecular formula, molecular weight, exact mass, degree of unsaturation (DBE), atom counts, and aromaticity analysis. • Save & Organize — Save drawings locally with search. Backup and restore your library as JSON. Selective export and import with conflict resolution. • Atom Properties — Set formal charge, isotope, explicit hydrogens, and aromatic flags on individual atoms. • Undo & Redo — Full history support for confident editing. • Clean Structure — Auto-optimize molecular geometry with force-directed layout. • Customizable — Adjust bond length, toggle skeletal mode, snap-to-grid, implicit hydrogen display, and per-element color themes.
