Floating Subtitles on Windows
This page covers the Windows setup for floating subtitles. For how it works and supported platforms, see the Floating Subtitles overview.
On Windows, Whisperr captures System audio — whatever you're hearing from a video, call, or any other app — and shows live subtitles in a small always-on-top floating window that stays visible over whatever else you're doing.
How to Use Floating Subtitles on Windows
- Download Whisperr for Windows (Windows 10 and later), run the installer, and launch Whisperr
- Set your languages: pick the language you're hearing under Speaking and the one to Translate to

- Switch the source toggle to 🔊 System audio — on Windows this captures your PC's playback directly, no extra setup needed

- Click the round record button — Whisperr transcribes everything playing on your PC and shows the translation live

- Play your video or join your call — subtitles update in real time as the audio plays. Use the Both / Transcription / Translation tabs to choose what's shown


- To keep subtitles on screen while you switch to something else, click the floating subtitles icon next to the full-screen button (in the same panel as the tabs above). It opens a small window that stays on top of everything else, so you're not stuck keeping the Whisperr window visible next to your content

- Click that same icon again to make the floating window transparent — instead of a solid panel, only the caption text shows, so whatever's behind the window (your video, a call, another app) stays fully visible. A third click closes the window; clicking once more re-opens it as a solid panel again

Solid panel (1st click)

Transparent (2nd click)
You can drag the floating window anywhere on screen, and it remembers its position and size the next time you open it. A small × in its corner closes it directly.
On Windows, the floating window stays on top of other apps' normal windows, but — unlike on Mac — it can't draw over an app running in exclusive full-screen mode. If a video or call is in exclusive full screen, switch it to windowed or borderless mode to keep subtitles visible.
Common Issues (Windows)
Subtitles are empty while audio plays
Confirm the audio is playing through the right output device and isn't muted: right-click the speaker icon in the taskbar, choose Sound settings, and check Output under System > Sound.
Microphone is selected instead of System audio
To subtitle what you're hearing (not what you say), make sure the source toggle shows 🔊 System audio, not 🎙️ Microphone.
Still nothing
Restart the app and try again.
