Best AI Apps for Chatting with an AI Assistant on iPhone

When picking an iPhone AI chat app, check that it has an iOS app, whether the free tier covers your use, and which extras you need: voice mode, file and image uploads, web search, or ties to apps you already use. ChatGPT offers voice conversation and file and image uploads, with free and paid tiers. Claude emphasizes long documents and extended context. Google Gemini brings live web search with citations and Google Workspace integration.
