What is AkashBoard?

AkashBoard is a free, open-source Android keyboard (FOSS) with a Rust prediction engine that genuinely learns how YOU type — not just generic word frequencies, but your timing, your context, your patterns, your personality. It runs entirely on your device. No cloud. No accounts. No data collection. Ever.

AkashBoard is the best alternative to Gboard, SwiftKey, and Samsung Keyboard for privacy-conscious users. It's a no-tracking keyboard with swipe typing, autocorrect, emoji support, clipboard history, and voice input — all running 100% locally on your Android device.

Built in 2 Days

This entire keyboard — from empty repository to production-ready APK with 227 passing tests — was built in 2 days (August 21-22, 2026). That's 12 weeks of planned work compressed into an intense sprint covering:

• 100% Jetpack Compose UI with 60FPS Bezier swipe trails (60-120 FPS)
• Rust prediction engine compiled to ARM64 native code via JNI
• Swipe/glide typing, auto-correct, 5 themes, emoji, clipboard, voice
• Elite Material 3 Jetpack Compose Settings Dashboard
• 227 passing tests (174 Kotlin + 53 Rust)

Why AkashBoard Exists

Every keyboard today has the same problem: they serve the company, not the user.

• Gboard sends your keystrokes to Google servers
• SwiftKey requires a Microsoft account and has ads
• Samsung Keyboard is locked to Samsung devices
• FOSS keyboards (OpenBoard, HeliBoard, FlorisBoard) are either incomplete, have no personal learning, or require proprietary blobs for basic features

AkashBoard fixes this: a FOSS keyboard that's actually BETTER than the closed-source ones.
