20+ Best AI Assistants for Android (2026)

Android users now have two main types of AI assistants in 2026.

First, there is the default phone assistant that you can activate with a power button long‑press or swipe gesture (where Google is actively moving users from Google Assistant to Gemini).

The second type is standalone AI apps that you open like any other app such as ChatGPT, Claude, Copilot, and Perplexity. These are especially good for search, research, and writing tasks.
