Tymender is a native macOS file renamer designed for users running macOS 14 or later. Its primary function is to transform disorganized filenames—such as those from screenshots, receipts, PDFs, images, archives, and notes—into clear, recognizable names. Rather than applying blind automation, Tymender analyzes each file using text recognition (OCR), dates, metadata, and file type clues to generate suggested names. The user then reviews and approves every proposed change before the renaming is applied, ensuring no unintended modifications occur. The application offers several key features for batch renaming. Users can send files from Finder, drag and drop them directly, or set up a watched folder to collect files automatically. All files appear in a single preview queue where users can search, filter, edit individual suggestions, or skip files entirely. After renaming, every batch is recorded in a history log that stores both the old and new names. This history can be exported as a summary or used to undo changes while the original file paths remain available. An optional local clipboard history feature remembers recent text copied with Command+C, making it easy to reuse snippets, titles, or references during the naming process. The typical workflow begins by gathering files from a messy folder—such as screenshots named IMG_4821, receipts, or PDFs with vague titles like "final-final." Tymender collects these files into a preview pane, where it displays the old name alongside the suggested new name and the reason for the suggestion. Users can quickly edit any suggestion, skip files that do not need renaming, and then apply the batch. The app keeps a clear trail back to the original filenames, and users can undo changes as long as the original path is still accessible. This approach avoids the need for regex rules or blind automation, giving users control over each rename while eliminating the guesswork of manual file organization.
