NameQuick combines content-aware AI renaming, reusable naming Presets, folder monitoring, file organization, and content search in one desktop workflow on Windows and Mac. It reads more than 30 file formats, including scanned documents through built-in OCR.

NameQuick's answer
NameQuick was created to solve a common macOS problem: useful files arrive with names such as Scan0042.pdf, IMG2847.jpg, or finalFINALv3.pdf, then become difficult to find and file consistently. The product began as an AI-assisted renamer and grew into a complete local file workflow with naming Presets, OCR, watch folders, content search, organization rules, rename history, and multiple AI options. It is developed by Synthropy in the Netherlands.
