Molecules in your browser—HN begs for a better title and a ‘Show HN’

TLDR: A browser tool lets anyone draw molecules and run fast, lab‑grade simulations, then share results with a link—no installs needed. The top reaction wasn’t about the science but the marketing: readers pushed for a proper “Show HN” post and a clearer title to match the tool’s accessibility mission.

A slick new tool claims “DFT-accuracy”—translation: lab‑grade physics results—right in your browser, no installs, no code. You can draw a molecule like you’re doodling, hit run, and boom: 3D models, energy charts, and a permanent share link via mace-lake.vercel.app. The dev even framed it around accessibility: making pro‑level chemistry tools usable for disabled scientists and students without fancy labs. The mission? Big. The execution? Surprisingly friendly. The community mood? Title wars. One early voice urged the creator to tag it as “Show HN” (Hacker News’ way to showcase projects) and begged for a clearer name. The subtext: this is too good to hide behind a vague headline.

Cue the drama: the classic HN meta‑debate where product polish meets headline chaos. The tool itself packs crowd‑pleasers—draw or upload molecules, auto‑generate 3D shapes, run fast AI‑powered simulations, then share a permanent link—yet the only actual scorch in the thread is about… branding. Still, that lone nudge carried weight, with readers reading between the lines: great tool, tell a better story. Jokes flew about “DFT in a tab” sounding like a new energy drink, and memes about “naming is the hardest problem in computer science” made cameo appearances. Verdict from the peanut gallery: impressive science toy turned serious tool—now give it a headline worthy of the buzz.

Key Points

  • Browser-based interface runs MACE-powered, DFT-accuracy atomistic simulations with no installation or command line.
  • Features include a Web Calculator, Multi-Model Benchmark, and Sketch-a-Molecule with real-time validation and descriptors.
  • 2D sketches are converted to 3D using ETKDGv3, multi-conformer sampling, MMFF94 optimization, and energy-ranked selection.
  • Results are shareable via permanent URLs (MACE Link) and stored in Supabase with row-level security, making them immutable.
  • Input options include drag-and-drop of .xyz, .cif, .poscar, .pdb files, an ml-peg catalog of 14 structures, or drawing molecules.
