Abstract

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 • 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 7 languages: English, French, German, Spanish, Portuguese (BR), Hindi, and Simplified Chinese • Zero analytics, zero tracking, zero telemetry • Tiny APK (~1.3 MB) with zero third-party networking dependencies Built-in commands: • ?fix — Fix grammar, spelling, and punctuation • ?improve — Improve clarity and readability • ?shorten — Shorten while keeping meaning • ?expand — Expand with more detail • ?formal — Rewrite in professional tone • ?casual — Rewrite in friendly tone • ?emoji — Add relevant emojis • ?reply — Generate a contextual reply • ?undo — Restore text from before the last replacement • ?translate:XX — Translate to any language You can also create your own custom AI commands with any prompt, or text replacer commands for instant offline snippets like signatures, canned responses, and shortcuts. An API key from Google Gemini (free tier available), Groq, or any OpenAI-compatible provider is needed for AI commands. Text replacer commands work without any API key.
