AtomLens for Mac

One purchase unlocks AtomLens on macOS and iPad: open, translate, highlight, save, preview, sync, and share molecule and chemical reaction files anywhere.

AtomLens helps you open, browse, and understand molecule and reaction files on macOS.

Whether you are reviewing a single structure, exploring a folder of chemistry files, or checking reaction data, AtomLens gives you a clear native Mac experience focused on readability, fast local workflows, and practical file handling.

Open common chemistry formats, inspect clean 2D depictions, review identifiers and calculated properties, and move quickly between Spotlight, Quick Look, and AtomLens’ built-in Molecule Browser. When needed, you can also extract multi-entry files into smaller outputs for downstream work.

What AtomLens can do:

• Open molecule and reaction files in a native macOS app
• Render clean 2D structure and reaction views
• Browse indexed local chemistry files with Molecule Browser
• Inspect identifiers and key properties such as formula, molecular weight, monoisotopic mass, LogP, and Rule-of-Five status
• Support modern notations including CXSMILES and selected Markush-related structure features
• Preview chemistry files through Quick Look and find them through Spotlight
• Filter and organize files with Finder labels inside Molecule Browser
• Extract multi-structure and multi-reaction files into separate outputs
• Export structures in practical chemistry and graphics formats

Supported input formats: MDL Molfile, SDFile, SMILES, CXSMILES, Reaction SMILES, InChI, MOL2, PDB, XYZ, CML, RXN, and RDF.

Built for local workflows: AtomLens is designed to work on your Mac without requiring cloud processing for normal use. Your chemistry files stay under your control.
