Key Differences
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.
Who Should Choose What?
