What Is an AI Assistant for Android?

An AI assistant for Android is an app (or built-in system tool) that uses large language models (LLMs) to help you think, work, search, plan, and get things done - directly on your Android device.

Unlike old-school assistants like Google Assistant, modern AI assistants can:

• understand natural language
• process photos, screenshots, voice, and documents
• help with real tasks (emails, notes, research, planning)
• learn from your context
• automate workflows
• summarize anything instantly

How I Tested These Android AI Assistants

I tested every app using the same simple, real-world checklist:

• Speed: how fast they respond to text, voice, and screenshots
• Accuracy: how well they reason, fact-check, and stay consistent
• Real tasks: summarizing files, writing emails, turning notes into tasks
• Mobile experience: UI, multitasking, and ease of use on Android
• Multimodal: handling photos, PDFs, voice, and uploads
• Value: what the free plan gives you vs. paid

These tests focus on practical daily use, not marketing claims.

Now let's dive in!
