Top Picks
ChatGPT — The default choice on iPhone, and the one with the fewest gaps. Voice conversations feel natural, you can snap photos and ask questions about them, and it handles everything from meal planning to code debugging. The free tier is enough for casual use.
Claude — Anthropic's app is cleaner and more focused than ChatGPT. Better at long-form writing, document analysis (upload PDFs directly), and thoughtful conversations. Artifacts feature lets you create and iterate on documents within the app.
Perplexity — Think of it as AI-powered Google. Ask any question and get sourced answers with citations. The Discover feed surfaces interesting topics. Best AI app for students and researchers who need facts, not opinions.
Google Gemini — Deep integration with Google services makes this powerful if you're in the Google ecosystem. Summarize Gmail threads, create Google Docs drafts, analyze Google Sheets. Gemini Live voice mode is excellent.
Canva — AI features baked into the design app you already use. Magic Write for text, Magic Eraser for photos, text-to-image generation. Enough of the everyday work — social posts, quick edits, simple decks — happens on the phone that opening the desktop app becomes the exception.
Grammarly — Works across every app via the iOS keyboard. Real-time writing suggestions, tone detection, and now AI-powered rewrites. Essential for anyone who writes emails or messages professionally.
Otter.ai — Records meetings and lectures, transcribes in real-time, and generates summaries. The iPhone app works offline for recording and syncs transcriptions when connected.

Frequently Asked Questions
What is the best free AI app for iPhone?
ChatGPT has the broadest free tier — voice conversations, image analysis and web browsing are all included, on whichever model OpenAI currently serves free accounts. Perplexity's free tier is also usable day to day: a daily allowance of its better "Pro" searches on top of unlimited basic ones. Both vendors change these limits often, so check in the app before you rely on a specific allowance.
Do AI apps drain iPhone battery?
Most AI processing happens on servers, not your phone, so battery impact is minimal during normal use. Voice mode in ChatGPT and Gemini uses more battery due to continuous microphone access. Background transcription in Otter.ai can be noticeable during long recordings.
Which AI app is best for students?
Perplexity for research (sourced answers with citations), ChatGPT for explaining concepts and study help, and Otter.ai for recording and transcribing lectures. All three have free tiers that cover student needs.
