RealSub: subtitles for whatever your PC plays

Editorial interest 76/100 Selection signal · not a rating of the site

RealSub is a Windows app that locally transcribes audio from the whole PC or a selected app, with optional translation in a floating subtitle bar.

Landing page captured for the 2026-10-09 issue.

For: Windows users watching audio without subtitles
Worth noticing: Near-continuous speech can trail by around 10 seconds during translation; the page identifies this as a design limitation, not a network fault.

Field notes

The app bundles its recognition and translation models, and the page says an account or API key is not needed to get started. Device selection can be automatic or pinned in Settings; Vulkan is tested on first run, and CPU mode is an automatic fallback, with lower accuracy and higher latency. The repository is described as the public home for downloads and documentation, not the application source code.
