Android Input Method Service implementation. Native Kotlin with the same Bifrost prediction backend powering intelligent suggestions across all platforms.

  • Android Input Method Service (IMS)
  • Gradle-based build with KTS scripts
  • Bifrost REST prediction backend
  • Custom theme engine
  • Material You integration (roadmap)
In Development

Core Features

🔄
Key Remapping

Full system-wide key remapping engine. Swap modifier keys, reassign function rows, create per-app profiles. Your layout, your rules.

Macro Expansion

Type `:for`, get a loop template. Define unlimited expansion macros — code snippets, boilerplate text, canned responses. Developer-first by design.

🎨
Theme Engine

Fully customisable visual themes for the keyboard and candidate window. Dark, light, arcane, tactical — or build your own from first principles.

🧠
AI Prediction

Bifrost-powered prediction engine. Learns your vocabulary and context. Cloud-sync across devices. Falls back to local prediction offline.

☁️
Cross-Device Sync

iCloud + Bifrost KV sync keeps your dictionary, macros, and remaps in sync across every Apple device. Android sync via account (roadmap).

🔒
Privacy First

Prediction model runs locally by default. Cloud sync is opt-in. Keystroke data never leaves your device without explicit consent.

Bifrost Intelligence

Powered by Bifrost Bridge

Grim Keys uses Bifrost — a Cloudflare Workers-based AI orchestration platform — to deliver low-latency prediction improvements from a centralised backend. All three platforms connect to the same prediction service, ensuring feature parity without redundant model work.
