Gotcha

Most things called an AI assistant on mobile are just a glorified text box: you ask, it types back a response, and you still have to manually open the calendar, copy text into another app, or trigger a script in Termux yourself. Gotcha is built to be different: a free, fully on-device, open-source copilot that looks at your screen or terminal output, understands context, and actually acts, using Android's Accessibility Services to navigate apps, tap buttons, and fill out forms just like a human would.

It runs bash scripts, Python code, git commands, and curl requests inside Termux directly from natural language commands, and connects natively to local LLM servers running on your own machine (Ollama, LM Studio, llama.cpp) or cloud models (Gemini, Groq, OpenAI), with native integrations for Home Assistant, Notion, Android Contacts, SMS, and Health Connect metrics. A local, offline wake-word engine, Hey Gotcha, works across nine languages.

Gotcha runs in two safety modes: an inspection-only mode that reads screen context with zero ability to send messages, change settings, or delete files, and a full-action mode bounded by explicit permissions the user grants, backed by an append-only audit log. It is fully open source, requires no account, and can be built from source or downloaded as a ready APK.
