Click the menu-bar icon, drop your files into the panel, and RoostTX handles the rest. Individual files, whole folders, or a mix — it walks folders recursively and processes everything it finds.
| Individual files | Drop any number of audio or video files at once |
| Folders | Drop a folder and the app finds every audio and video file inside, including subfolders |
| Spring-loaded icon | Drag files directly to the menu-bar icon — hold for a moment and the panel springs open automatically |
| Pin | Keep the panel open while dragging from Finder with the pushpin in the title bar |
Every transcribed file produces two outputs, written to your chosen folder automatically.
| Plain text | The spoken words, nothing else. ready to copy, edit, or search |
| Text with timecode | Pick your preferred timing and RoostTX will track |
Select the SRT button in the title bar and done. RoostTX tracks the timecode when dialogue is spoken. Names, and formatted so you can immediately drop it into any video playback program.
Transcription runs entirely on-device using Apple's built-in speech engine. Your audio is never sent to Apple or anywhere else. No microphone permission required — the app reads files from disk only.
The first time you transcribe in a language, macOS may download a language model for that locale. That one-time download requires an internet connection; all subsequent transcriptions work offline.
