MCP Tools: Connect Model Context Protocol (MCP) servers so the Agent can discover and use external tools such as filesystem, search, document, memory, or custom hosted tools. MCP calls require user approval before execution. Termux Command Generation (Android): Automatically drafts shell/CLI commands targeting Termux environment execution (RUN_COMMAND_SERVICE intent interface). Interactive Pre-Execution Editing: Users can inspect and edit AI-generated shell commands before execution. Live Dark Terminal Container: Formats and streams live command outputs (stdout/stderr) in a dark monospace terminal UI block. AI Error Auto-Correction Loop: When a shell command fails or encounters permission/syntax errors, the agent automatically feeds the error logs back into the LLM for self-diagnostics and auto-generates fix commands. 🎙️ Supported ASR Models (Android) The offline Transcriber feature on Android supports on-device Whisper models for high-accuracy local speech-to-text. 🔊 Android Text to Speech & Voice Cloning Kokoro: Local speech with downloadable voices managed in Settings. Supertonic 3: Multilingual on-device speech with downloadable presets and import of compatible voice-style JSON files. Raw audio cloning and Pocket TTS voice states are not supported by Supertonic's importer. See Supertonic 3 setup. Pocket TTS: English speech and fully local voice cloning from recorded or imported audio. Manage, select, rename and delete cloned voices in Settings. Cloning uses 3–30 seconds of reference audio; longer imports use their first 30 seconds. See Pocket TTS setup. Selecting an engine and voice in Settings applies it to app-wide speech and auto-readout. Translator keeps system TTS. 🔎 Media Search & Video Moment Finder On Android and iOS, Instant Media Search uses EmbeddingGemma 2 to index photos and videos locally, then find matches from a text description or reference image.
