QuietKey vs Sogou
Sogou is China's most popular keyboard with excellent Chinese input. QuietKey offers better privacy, English support, and AI features.
Sogou is unmatched for Chinese input, but comes with serious privacy trade-offs. If you primarily type in Chinese and trust Tencent with your data, Sogou is excellent. But if you need English support, care about privacy, or want AI writing features, QuietKey is the better choice.

Where they differ
Privacy and security
Sogou is owned by Tencent and sends data to China. Citizen Lab found security vulnerabilities that exposed keystrokes to network eavesdroppers.
QuietKey only sends AI-related text to OpenAI. Your regular typing stays on your device. Privacy-first by design.
Chinese input quality
Sogou is the gold standard for Chinese input. Excellent pinyin, handwriting, and voice recognition tuned for Mandarin.
QuietKey offers solid CJK support but doesn't match Sogou's Chinese-specific optimizations.
English support
Sogou has weak English autocorrect and voice recognition. It's designed for Chinese users, English is an afterthought.
QuietKey uses Whisper for 99%+ English accuracy and has strong English autocorrect. Great for multilingual users.
AI features
Sogou focuses on input methods, not AI writing. No tone adjustment, no custom prompts, no automatic rewording.
QuietKey has GPT-level AI rewording, tone presets, and unlimited custom prompts built in.
