QuietKey vs HeliBoard
HeliBoard is a privacy-first, open-source keyboard that works 100% offline. QuietKey adds AI-powered dictation and rewording for productivity.
HeliBoard is perfect for privacy purists who want zero network activity. But if you dictate regularly or want AI assistance with writing, QuietKey delivers features HeliBoard can't match. It's privacy vs. productivity.

Where they differ
Privacy approach
HeliBoard is the ultimate privacy keyboard, it has no internet permission at all. Zero data leaves your device, ever.
QuietKey sends audio to the cloud for AI processing but offers typing privacy. It's a trade-off for powerful features.
AI capabilities
HeliBoard has no AI features. It's a traditional keyboard with dictionary-based autocorrect.
QuietKey includes Whisper dictation, GPT rewording, tone adjustment, and translation, all powered by AI.
Customization
HeliBoard is extremely customizable, themes, layouts, colors, fonts, gesture behavior, toolbar, and more.
QuietKey offers customization for themes and keyboard height, but HeliBoard goes deeper with open-source flexibility.
Ease of setup
HeliBoard requires manual configuration, dictionaries, glide typing library, and settings tweaking for best results.
QuietKey works out of the box with sensible defaults. AI features just work without configuration.
