Maid is a free, open-source Android app for running llama.cpp GGUF models fully on-device, or connecting to Anthropic, DeepSeek, Mistral, Ollama and OpenAI models remotely. Keys are entered per remote provider inside the app, with no account and no Maid-hosted proxy involved; local inference needs no key and no internet connection at all. Distributed through Google Play and GitHub releases. MIT licensed, 2,629 stars, pushed within a month of review.

How this tool was scored

Key handling 88/100 (where your key rests and who sees it, comparable across any licence) and verifiability 70/100 (how much of that BYOAIK could confirm, lower for closed source). Neither contains a popularity signal.

  • Key Safety 23/25: The key is held on your own device.
  • Request Routing 17/20: Requests go straight from you to the AI provider.
  • Transparency 20/20: Source is public under MIT, so anyone can check how the key is handled.
  • Privacy 13/15: Local-first: it works without sending your data anywhere. The project states it sends no telemetry.
  • Maintenance 10/10: Actively developed, with commits within the last three months.
  • Verification Confidence 1/10: Compiled from public documentation by an AI-assisted pass, not independently confirmed.
