We also work with component manufacturers to help them create or translate their content to various formats. Here's an example: https://www.snapeda.com/parts/4N32-X001/Vishay/view-part/.
User-generated content is supported due to popular demand, but we deprioritize it in favor of semiconductor-generated, or SnapEDA-generated content. We also have an automated verification checker that exposes the quality of UGC on each part page.
