Chatbot for Android

Gemini is built into Android — accessible from the lock screen, replaces Google Assistant, and integrates with Pixel hardware.

Gemini is Google's AI assistant, now built on Gemini 3.1 Pro and deeply integrated with Google Workspace, Search, and Gmail. It handles text, images, code, audio, and video natively — the broadest multimodal range of any major AI chatbot. Free with a Google account (Gemini 3.6 Flash default); Google AI Plus ($4.99/month) raises usage limits, Google AI Pro ($19.99/month) unlocks full Gemini 3.1 Pro access plus the new Gemini 3.7 Flash (via Spark), and Google AI Ultra ($99.99-$199.99/month) adds the highest usage tiers and Deep Think.

ChatGPT for Android matches the iOS app feature-for-feature — voice mode, image uploads, and the best third-party AI experience on Android.

ChatGPT is OpenAI's flagship AI assistant, used by hundreds of millions of people worldwide. As of August 2026, Free and Go users default to GPT-5.6 Luna with unlimited text chats, while Plus and Pro users default to GPT-5.5 Instant for everyday chat, with GPT-5.6 Sol as OpenAI's flagship reasoning model for complex work in coding, research, science, and cybersecurity. It handles text, code, image generation, voice conversations, web search, and file analysis — making it one of the most feature-complete general-purpose AI chatbots available. ChatGPT Plus ($20/month) unlocks GPT-5.6 Sol reasoning, and Pro (from $100/month) adds GPT-5.6 Sol Pro with maximum usage.

Claude on Android is fast, generous on the free tier, and exceptional at reading and summarizing long documents.

Claude is Anthropic's AI assistant, built for accuracy, nuance, and careful reasoning. It runs on the Claude 5 model family — Opus 5 for complex analysis and deep research, Sonnet 5 for everyday work, and Fable 5 for extended, multi-step coding and knowledge-work projects — alongside Haiku 4.5 for fast, lightweight tasks. Claude handles text, code, documents, images, web search, and voice, with a 200,000-token context window. It remains the preferred choice for researchers, writers, and developers who prioritize careful, trustworthy output over raw speed.

Perplexity AI has one of the highest-rated Android AI apps — real-time web search with citations in a clean interface.

Perplexity is an AI-powered search engine that answers questions with cited sources from the live web. Every response links directly to primary sources — making it the most transparent AI assistant for research and fact-checking. Free users get unlimited web searches; Pro ($20/month) unlocks per-query choice among GPT-5.6 Sol, Claude Opus 5, and Gemini 3.1 Pro; Max ($200/month) adds Model Council, which runs a query across all three simultaneously and synthesizes the results.

Microsoft Copilot for Android is the best free option for users who want GPT-5.6-class AI without a subscription.
