SwiftSlate

SwiftSlate is a system-wide AI text assistant for Android. Type a trigger like "?fix" at the end of any text, in any app, and watch it get replaced instantly.

It works in most apps — WhatsApp, Gmail, Twitter/X, Messages, Notes, and more. No copy-pasting. No app switching. Just type and go.

Features:

• Works system-wide via Android's Accessibility Service

• Also works from the text-selection menu in any app — no accessibility permission required

• Instant inline text replacement — AI response replaces your text directly

• Multi-provider AI: Google Gemini, Groq, or any OpenAI-compatible endpoint (including local LLMs like Ollama and LM Studio)

• Text replacer commands run entirely offline with zero latency

• Multi-key rotation with automatic rate-limit handling

• API keys encrypted with AES-256-GCM via Android Keystore

• AMOLED dark theme and light theme with Material 3

• Localized in 40 languages — the app follows your device language automatically

• Zero analytics, zero tracking, zero telemetry

• Tiny APK (~1.7 MB) with zero third-party networking dependencies
