Small tools that make macOS easier to understand.

AtomLens

Obscure Essentials™ Open molecule and reaction files Extract split batches Search with Spotlight

AtomLens is a native macOS chemistry workbench for molecules and reactions. Open common chemistry formats, view clean 2D structures and reaction schemes, split multi-entry files into reusable outputs, generate identifiers and properties, and find results quickly with Spotlight and Quick Look integration.

QL Provider Inspector

Obscure Essentials™ Inspect UTIs Find Quick Look providers See default viewer/editor

Inspect a file or folder and see its Uniform Type Identifier (UTI), conformance tree, which Quick Look providers claim support, and which apps are registered as default viewer/editor.

CDKSwiftNativePort

CDKSwiftNativePort is a Swift-native chemistry toolkit package inspired by the Chemistry Development Kit (CDK). In simple terms, it helps developers read and write common molecule formats, generate identifiers like SMILES/InChI, create 2D depictions, and compute core molecular properties inside native Swift projects.
