Top best AI apps for iPhone
ChatGPT
First and foremost is ChatGPT, an indispensable AI app on the iPhone that can support almost every daily need. People can use ChatGPT to ask questions, search for information, write emails, compose blog posts, plan tasks, summarize documents, or simply chat when they need someone to listen. Currently, the app also supports group chats with friends.
ChatGPT is also renowned for its ability to create high-quality AI images, having previously created a craze for Studio Ghibli-style photography. The latest GPT-5.2 version offers faster response times and significantly improved contextual understanding.

Perplexity
Perplexity is the AI app I use most on my iPhone, primarily because it's currently the best Siri alternative. The app functions as a standalone AI chatbot, usable for research, summarizing documents, explaining concepts, or developing ideas, much like ChatGPT.
The most notable feature is Voice Mode. Users can ask Perplexity to play music on Apple Music, add events to Apple Calendar, send emails to contacts, or perform many other tasks using their voice.

In addition to providing explanations, summaries, and Q&A, Gemini also features Gemini Live, allowing users to point the camera at any object and ask questions directly about what they see. This feature is especially useful in real-world situations requiring immediate guidance.

Users can record lectures, meetings, or interviews and then review the recordings anytime. Otter also automatically identifies the speaker, records, creates summaries, and shares notes with colleagues.
