MolSketchGo

Draw molecules in 2D, explore in 3D, and export SMILES, MOL, PNG & more. PubChem search built in. Optional Pro removes banner ads.

MolSketchGo is a mobile tool for drawing and exploring chemical structures—for study and personal use. It is not intended for professional, safety-critical, or regulatory decisions.

DRAW STRUCTURES • Tap to place atoms; drag between atoms to create bonds • Single, double, triple, wedge, and dash bonds • Long-press to move atoms; use two fingers to pan and zoom • Ring templates: benzene, cyclohexane, and cyclopentane • Skeletal mode, implicit hydrogens, and valence warnings when bonds exceed typical valence

EXPLORE IN 3D • Generate a 3D view from your 2D sketch • Ball-and-stick, space-filling, and stick representations • Rotate and zoom

IMPORT & EXPORT • Export PNG, SVG, SMILES, MOL, and SDF on device • InChI and IUPAC names require an internet connection via PubChem (NCBI) • Import SMILES and MOL/SDF files • Search PubChem by name, CID, or SMILES • Import PDB structures from RCSB for 3D viewing (3D viewer; not editable in 2D)

MOLECULE INFO • Molecular formula, molecular weight, and DBE • Autosave drafts; dark mode and editor settings
