Input switching is clumsy
SMILES, CAS, and compound names often need different tools.
CHEMICAL STRUCTURE EDITOR
MolSketch
Search 10,000+ library entries, generate structures from SMILES, CAS, or compound names, then refine and export directly in the browser.
PROBLEM
Chemical structure work usually slows down before the drawing even starts.
Input prep, redraws, and disconnected export steps eat time before the actual chemistry work begins.
Complex structures are tedious
Large molecules get harder to clean up in rigid editors.
History and output are split
Editing, saving, and exporting end up in separate flows.
SOLUTION
Search, generation, editing, and export live in one browser workflow.
No install and no registration. Start from what you already know and finish in the same place. MolSketch resolves more than 100 million structures from common text inputs and sends the result straight into the editor.
10,000+100M+ generation
Generate structures from SMILES, CAS, or compound names.
FEATURES
The core tools stay close to the actual structure workflow.
Find, generate, adjust, and export without losing momentum.
10,000+ library
Start from a large built-in structure set.
100M+ generation
Resolve structures from SMILES, CAS, and compound names.
Free editing
Adjust bonds and layouts without rigid constraints.
Complex structures handled well
Large molecules remain practical to inspect and refine.
Export support
Output clean structures when you are ready.
History saving
Keep a trail of created work for later review.
HOW IT WORKS
Finish a structure in three steps.
Enter, refine, export.
Enter
Start from SMILES, CAS, a compound name, or the library.
Refine
Tidy bonds and layouts until it looks right.
Export
Download as SVG and keep the history if you need to return.
Start chemical structure work from the information you already have.
Search the library, generate from text, edit freely, and export in one browser session.
Free to use, no signup required.
No install, no account, and no fee before you can begin.
