Search Google Play for "AI" and you'll get hundreds of results, many of them thin wrappers that charge weekly subscriptions for access to someone else's model. The AI apps for Android that are actually worth installing are a much shorter list: a few general assistants from the companies that build the models, plus a handful of specialists that do one job well.

This guide covers both, then spends equal time on what to watch for, because the tradeoffs with AI apps (data use, ads, permissions and plain wrong answers) are bigger than with most software. Everything here was checked against Google Play listings and official help pages in October 2026. It's research, not hands-on benchmarking, and the judgments are labeled as opinions.

The general assistants

All four of these can chat, write, summarize, answer questions about photos and documents, and hold a voice conversation. The differences are in what they connect to and how they make money.

Google Gemini

On many Android phones, Gemini is already the default assistant, which gives it an advantage nothing else can match: it can connect to Gmail, Calendar, Google Photos, YouTube and Search. Gemini Live lets you talk through a problem in real time and share your camera or screen. Image generation and editing are built in, and video generation is reserved for paid Google AI plans. If most of your life runs through a Google account, it's the obvious starting point.

ChatGPT

ChatGPT remains the most widely known assistant, with a strong voice mode, image generation and photo understanding. The big change in 2026 is advertising: OpenAI began showing ads to Free and Go users in the US in February, while Plus, Pro and business plans stay ad-free. OpenAI says ads aren't shown to accounts it identifies as under 18. If you'd rather not see them, that's now a real point in favor of paying or picking another app.

Claude

Claude, from Anthropic, is aimed at writing, research, analysis and programming. It's free to start, with paid plans for heavier use, and its Play listing shows no ads. In our view it suits people who want help drafting and editing longer documents more than quick trivia answers.

Microsoft Copilot

Microsoft merged its consumer Copilot app and its Microsoft 365 Copilot app into a single Microsoft Copilot app starting in August 2026. It handles both personal and work accounts, keeps their chats separate, and can create Word documents, PowerPoint decks and Excel sheets from a conversation. If your files live in OneDrive or your employer uses Microsoft 365, it's the most useful of the four. Its Play listing notes that it contains ads.

The specialists

Perplexity: search with citations

Perplexity works like a search engine that writes the answer for you, with numbered sources under each response so you can check them. It's free, with a Pro tier for deeper searches. It's the one to reach for when you need current information and want to see where it came from.

Gemini Notebook: answers from your own documents

Google renamed NotebookLM to Gemini Notebook in July 2026; the tool and your existing notebooks are unchanged. You upload PDFs, web pages, YouTube videos or text, and it answers questions using only those sources, with inline citations. It can also turn them into podcast-style Audio Overviews, which the Android app plays in the background and offline. Students and anyone reading long reports will get the most from it.

Otter: meeting and lecture transcripts

Otter records and transcribes in real time, then produces summaries and lets you ask questions about the recording. It works for in-person conversations as well as Zoom, Google Meet and Teams calls. Transcription covers English, Spanish and French only, and the free plan has usage limits.

What to watch for

Copycat apps

Play has plenty of apps with names like "AI Chat Assistant" that use familiar-looking icons. Before installing, check the publisher name under the title against the table above. If an app asks for a subscription before you've asked it a single question, back out.

Whether your chats train the model

Most assistants can use your conversations to improve their models unless you change a setting. In ChatGPT, it's the "Improve the model for everyone" toggle under Settings > Data controls. Google's Gemini help pages say a subset of chats are read by human reviewers when the Keep Activity setting is on, and advise against entering anything confidential. Check the equivalent setting in whichever app you use, and keep passwords, medical details and work secrets out of chats regardless.

Where your data goes

DeepSeek's Android app is popular and free, but its privacy policy states that it collects, processes and stores personal data in the People's Republic of China. That doesn't make it unusable, but it's a reason to keep sensitive material out of it, and some employers and governments restrict it on work devices.

Permissions

Screen-sharing features are useful but powerful. ChatGPT's optional screen feature uses Android's Accessibility Services, which can read what's on your display. Grant that kind of access only to apps you trust, and review it periodically using our Android privacy and security checklist.

Confident wrong answers

Every assistant on this list can state something false with complete confidence. Use citations when they're offered, and verify anything involving money, health or law.

A practical starting setup

Install one general assistant that matches your accounts: Gemini for Google users, Copilot for Microsoft 365 users, or ChatGPT or Claude if you have no strong tie to either. Add Perplexity for researched answers and Gemini Notebook if you read long documents. Then spend two minutes in each app's data settings before you start.
