Aide (French for assistant) is a hybrid, private-first Android app that puts a frontier-class AI model on the surfaces you already use: the system keyboard and the assistant button. Local-first; cloud is opt-in.
Runs Gemma 4 on-device via LiteRT-LM. For heavier weights (Gemma 4 26B / 31B), an optional Ollama endpoint takes over. Chat, keyboard, and assistant share the same loaded model.

A single workspace that fronts every surface: chat, keyboard, assistant, models, and tool permissions.
Multi-chat workspace with markdown replies, image input that Gemma 4 reads as a multimodal turn, and a tappable thinking chip that opens the model's reasoning trace.
Pick a local Gemma 4 weight (E2B / E4B) or point at an Ollama endpoint for heavier weights. Selection is per-chat, swappable mid-session.
A real Android InputMethodService with a transform bar above the keys (rephrase, simplify, fix grammar, summarize, tone shifts, key points, bullets, table view, three-reply suggestions) and a magic button for one-shot Custom Instructions. Every transform is a row in a local task table — edit the prompt, reorder, delete, or add your own with a {{text}} template.
37 languages on the transform bar, paired with 20+ on-device STT models. The keyboard can listen in one language and write back in another without phoning home.
Long-press the assistant button for a turn-based voice loop: STT → Silero VAD → Gemma 4 → TTS, on-device by default.
Gemma 4's native function calling drives a single dispatcher for alarms, calendar, contacts, phone, clipboard, filesystem, web search (Tavily, Brave, DuckDuckGo, Ollama), calculator, and time. Per-category toggles in settings; destructive actions route through an INFO / WARN / DANGER confirmation gate.
Roughly 23 Piper, Kokoro, MeloTTS, and Matcha voices across 10+ languages for output; Zipformer, Whisper, Moonshine, Parakeet, SenseVoice, and GigaAM for input. Auto / Sherpa / System is a per-surface choice.
