TobiBoard is a fast, private Android keyboard that runs entirely on your device — a fork of HeliBoard with all of its offline typing, glide, autocorrect, suggestions and dictionaries. On top of that it adds two optional AI helpers you switch on with your own API key, or ignore completely.

Two optional AI features

• Voice-to-Text — long-press Return, tap the mic, speak; your words land as polished text.
• Text Fix — select rough text, hit Fix; get back a clean, well-formatted message in the same language.

Both are off by default and only run when you add your own OpenRouter or PayPerQ key. Nothing leaves your device until you opt in, and OpenRouter routes default to zero data retention. No account, no subscription, no telemetry, no backend.

Get it

• APK — download from GitHub Releases.
• Automatic updates — install Obtainium and point it at this GitHub repo; it tracks new releases for you, no store needed.
• IzzyOnDroid — inclusion request submitted, in review.

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

Open source

GPL-3.0, forked from HeliBoard (AOSP / OpenBoard lineage). Everyday typing stays fully on-device; the two AI features are the only part that reaches the cloud, and only with your own key. Source and build instructions: github.com/leinss/TobiBoard.
