Hello. I created Keynap, a local voice input app exclusively for Windows.

The reasons I developed this app are:

1. While Mac has both standard voice input and plenty of good voice input apps, I couldn't find one for Windows that had the feel I wanted.

2. I did not want to send all the audio input on my PC to the cloud.

3. I wanted to avoid paying ongoing subscriptions for input tools.

Main features: - Supports English, Spanish, French, German, Japanese, Chinese, Korean, and more.

- Runs fast on CPUs (even faster with a GPU).

- Completely local, on-device processing.

- Distributed via Microsoft Store with automatic updates.

- Voice input is free and unlimited (some premium features are one-time purchases).

As I am a native Japanese speaker, I would appreciate your feedback on whether it works comfortably in languages other than Japanese.

As a thank you for trying it out, I will give away perpetual licenses for premium features to the first few people→ http://go.microsoft.com/fwlink/?LinkId=532540&mstoken=JGVTF-...

Hi. Sounds interesting. However, I don't use Microsoft store. Could you provide a downloadable exe perhaps? Thanks.

Thank you for your comment. I am sorry, but I cannot provide an exe file. This is because Microsoft Store handles the signing of the software. Please understand that this is for security reasons.
