Tester feedback, made concrete
0.67h turns hands-on Windows alpha feedback into clearer editor states, safer image review, and an export workflow that tells you exactly where your chemistry went.
WHAT CHANGED
Private by default
NewChem™ keeps your molecule library on your machine. Open it without an account, use it without a subscription, and back it up or move it whenever you choose.
Features that need the internet say so. The public installer starts empty, and your personal library never has to leave your computer for everyday work.
Ten focused tools
01
Turn a structure image into an editable molecule. This Estradiol example preserves a fused four-ring steroid framework and defined stereochemistry in one local recognition pass.
02
Bring analytical evidence into the same local workspace. Inspect infrared traces or mass spectra, work with peaks, and export the result without handing your files to a hosted viewer.
Shipped in 0.67k
Name, SMILES, InChI, CAS, and substructure search; local records, verified-name states, locking, notes, properties, and export.
Recognize a structure image locally, edit it, acknowledge the review, and hand the result to search or storage.
Open MGF data, inspect scans and chromatograms, interact with peaks, and review matched adducts.
Open common instrument exports, correct baselines, label bands, track edits, and export spectra.
Generate practical starting-method recommendations from the structure currently selected in your library.
Rank solvent-system starting points for crystallization from the selected molecular structure.
Run bench calculations for mass, mmol, concentration, scale-up, density, and stock solutions.
Estimate pressure-dependent boiling points from a curated local solvent dataset.
Generate and inspect a local RDKit conformer for the selected molecule.
Search curated cofactor records and follow enzyme and molecule cross-links.
Prefer a terminal? The included newchem command exposes stable JSON workflows across the library, ChemScan, FTIR, Masster, EZ-LC, EZ-Cryst, Converter, Boiler, 3D View, Cofactors, configuration, and database inspection.
NewChem™ 0.67k
Keep molecules, spectra, calculations, and decisions together on your own machine. No account. No subscription.
The complete source archive contains the exact NewChem source commit, build scripts, and source for the redistributed GPL/LGPL components. No Dropbox account is required. One heads-up: the builds are unsigned, so Windows or macOS may ask you to confirm the first launch.
You found it early
NewChem™ is being built in the open for people who want capable tools, private data, and ownership of their work. Welcome to the movement.
