How trust works

Keyboard with optional AI voice-to-text and text fix. Core typing runs locally, while AI features require a user-supplied API key for OpenRouter or PayPerQ. Includes multilingual support, clipboard history, and privacy-focused data handling.

WisprBoard is a privacy-first Android keyboard, forked from HeliBoard (which is based on AOSP / OpenBoard). Core typing runs locally on-device. Two optional AI features — Voice-to-Text and Text Fix — only run when you turn them on and supply your own API key.

No accounts. No subscription. No telemetry. No backend. Bring your own key.

AI Voice-to-Text Long-press Return, tap the mic, speak. Your words land as polished text.

AI Text Fix Select rough text, long-press Return, hit Fix. Get back a clean message in the same language.

Zero Data Retention WisprBoard requests OpenRouter zero-data-retention endpoints by default. When the model offers a ZDR route, your audio and text aren't logged, stored, or used for training. API keys are encrypted with the Android Keystore, excluded from cloud backups, and never written to logs.

All the HeliBoard features you expect

Privacy footnote Once your audio or selected text reaches OpenRouter, PayPerQ, or the underlying model provider, their policies apply. Read their privacy terms before pointing this at anything sensitive.

WisprBoard installs side-by-side with HeliBoard, so you can keep both.
