Aurora vs Windows Live Captions: Translation and PC Requirements
Aurora Subtitles is the better fit when you need its local translation presets without a Copilot+ prerequisite, a configurable overlay and a supported source/target language pair. It runs on compatible Windows 11 PCs with optional GPU acceleration. If you only need captions already covered by Windows, the built-in feature may be sufficient.
Comparing more options? See the Aurora, Chrome, Windows, StreamVox and Vibe decision guide.
What Windows Live Captions already does
Microsoft documents on-device captions for PC audio and microphone input. Translation is available on Copilot+ PCs, with English or simplified Chinese output and supported source languages. Check your Windows build and language availability in Microsoft’s Live Captions guide.
Both products process their core captions locally. Privacy alone is therefore not a reason to dismiss the built-in option.
Compare the workflow before choosing
| Decision | Windows Live Captions | Aurora Subtitles |
|---|---|---|
| Installation | Windows feature | Separate Windows 11 x64 app |
| Translation | Check Copilot+ and language requirements above | Preset and available source/target language determine the route |
| Dedicated GPU | Depends on the feature and device requirements | Optional; see CPU presets below |
| Caption display | Built-in caption window | Configurable position, font, background and click-through overlay |
| Payment | Included Windows feature | Paid lifetime license for the current product; Early Access updates included |
This is a documented feature comparison, not a side-by-side accuracy or latency benchmark.
Can Aurora run without NVIDIA?
Yes. Maximum Compatibility transcribes all 28 documented languages and translates between any pair in that list entirely on CPU. Maximum Quality supports the source and target languages available in Aurora, uses GPU acceleration when available, and falls back to CPU automatically.
CPU fallback does not mean every PC delivers the same speed. Audio quality, language, selected models and competing workloads affect results. See the CPU-only guide for its complete language list and current requirements.
Which is a better fit?
Start with Windows Live Captions when it covers your caption language and display needs. Consider Aurora when you want its configurable overlay, supported translation targets and one-time licensing for repeated desktop use.
For Discord voice chat, Aurora listens to Windows audio without joining the call. In Both (experimental) mode, microphone events stay in Session Activity rather than the overlay; it is not a promise of two-way translated speech.
Watch Aurora’s demo, then check requirements and license terms before buying. The download is for license holders. Neither a feature list nor an AI caption app guarantees perfect understanding of overlapping speech.
