About

MolSketch is a production-ready, browser-based chemical structure editor built for researchers, university students, educators, and chemistry professionals.Since launching in April 2026, the platform has grown organically to approximately 2,000 monthly users and around 50 registered users, with no paid advertising. This early traction demonstrates demand for a simple, accessible alternative to traditional installed chemical drawing software.Users can create and edit chemical structures directly in the browser without installing any software. Structures can be drawn manually or generated from compound names, CAS numbers, SMILES, and uploaded chemical structure images using OCR.Key features include:Browser-based chemical structure drawing and editingChemical structure recognition from uploaded imagesStructure generation from compound names, CAS numbers, and SMILESFlexible editing of atoms, bonds, rings, labels, colors, and display stylesPNG and SVG exportDrawing history and structure managementGoogle authentication and cross-device access for registered usersBuilt-in chemical structure libraryBuilt-in chemistry blog and content management systemAdmin dashboard with user management and analyticsResponsive desktop, tablet, and mobile interfaceMultilingual support across Japanese, English, Chinese, Korean, German, Spanish, and FrenchMolSketch is currently pre-revenue. Monetization has intentionally not yet been implemented, leaving significant upside for a buyer.Potential monetization opportunities include a Pro subscription, higher usage limits, developer APIs for chemical structure processing, an embeddable chemical editor for third-party products, premium cloud storage and exports, and continued expansion of SEO-focused chemistry content.The business is lightweight to operate and has grown without paid acquisition. The sale includes the production codebase, MolSketch domain, brand assets, website content, admin system, and associated product data.I am selling the project because I have limited time to continue developing and growing it alongside other commitments. The product is already live and operational, giving a buyer an existing user base and a ready-made foundation for monetization and further growth.
