The ultimate founder launchpad: Cap tables, equity & 409As

Hi Product Hunt! I’m building MolSketch，a free browser-based chemical structure editor for chemistry students，researchers，and anyone who needs to quickly draw and export chemical structures. The goal is to make common structure-drawing tasks easier without installing desktop software. You can draw atoms，bonds，charges，arrows，rings，and text directly in the browser，then copy or download the result as PNG or SVG. MolSketch also includes reusable structure libraries，templates，editing history with undo / redo and timeline jumping，mobile support，and structure generation from SMILES，compound names，CAS numbers，OCR，and handwritten images. It’s still improving，so I’d love feedback from chemists，students，researchers，and anyone who works with molecular structures. Thanks for checking it out!
