Quick picks: the short list

• Best overall: ChatGPT
• Best for writing: Claude
• Best for cited research: Perplexity
• Best free and built-in: Apple Intelligence
• Best for studying your own files: Google NotebookLM
• Best for fixing photos: Remini

Best all-round AI chatbots

These are the "ask me anything" apps. Use them to write, plan, learn, code, and solve problems by typing or talking. Every one has a usable free tier, so start here before paying for anything.

1. ChatGPT — best overall

ChatGPT from OpenAI is the app that kicked off the AI boom, and it is still the one we open most. The free tier now runs on GPT-5.2 with web search, image and file uploads, and image creation built in, while paid plans unlock the newer GPT-5.5 models.

• Best for: Writing, brainstorming, coding help, and everyday questions.
• Key features: Advanced Voice mode you can talk to hands-free, camera vision so you can point your phone at something and ask about it, file and photo uploads, and custom GPTs.
• Price: Free; ChatGPT Go is about $8/month and Plus is $19.99/month for GPT-5.5 access, higher limits, and more voice time.

Our take: If you only install one AI app, make it this one. The free tier handles most everyday tasks, and Plus is only worth it if you hit limits daily.

2. Claude — best for writing

Claude by Anthropic is our go-to when we want clean, natural writing and careful reasoning. It climbed to the top of the App Store's productivity charts in early 2026, and its flagship Opus model is excellent with long documents.

• Best for: Essays, emails, summaries, and reading or analyzing long PDFs.
• Key features: Upload a long document and have it explained or shortened, Projects to keep context across chats, and writing that reads the most human of any chatbot we tested.
• Price: Free; Claude Pro is $20/month and includes the flagship Opus reasoning model.

Our take: When a reply needs to feel polished or a document needs careful editing, Claude is the one we reach for.

3. Google Gemini — best for Google users

Gemini is Google's AI, now running the Gemini 3 generation. If you live in Gmail, Docs, and Google Calendar, it slots in naturally and can act across them.

• Best for: People who use Google apps every day.
• Key features: Pulls context from your Gmail and Drive (with permission), strong image generation, and a capable voice/Live mode.
• Price: Free; Google AI Pro is about $20/month, with a higher Ultra tier for power users.

4. Perplexity — best for research

Perplexity works like a smart answer engine. It searches the web first, then gives you a written answer with linked sources so you can verify every claim.

• Best for: Homework, fact-checking, and quick research you can trust.
• Key features: Inline citations on every answer, follow-up questions, and a Pro mode that lets you pick which model answers each query.
• Price: Free; Perplexity Pro is about $20/month.

Our take: When we need facts we can double-check, we skip a plain web search and start here.

5. Microsoft Copilot — best for free image making

Microsoft Copilot (formerly Bing AI) is a solid free chatbot that also generates images and ties neatly into Microsoft 365.

• Best for: Free image creation and people in Word, Excel, and Outlook.

How we picked and tested

We did not copy an App Store chart. We installed each app on iPhones running the current version of iOS and used them for real tasks over several weeks, then judged every one on the same checklist:

• Does the free tier actually work? We rejected apps that lock everything meaningful behind a paywall.
• Is it pleasant on a phone? We looked for clean interfaces without constant pop-ups or aggressive upsells.
• Does it do its one job well? We compared chat quality, transcription accuracy, photo results, and citation reliability against rivals.
• Is it from a trustworthy maker? We stuck to apps from real companies and skipped sketchy clones with no track record.

We also re-checked pricing and feature availability in June 2026, because AI apps change their models and tiers often. Where a precise figure was uncertain, we describe it qualitatively rather than guess.

Free vs. paid: which should you get?

Start free. Almost every app here has a genuinely useful free tier, and you only need to pay once you hit a daily limit or want the newest models. If you do upgrade, pick the single app you use every day rather than stacking multiple $20 subscriptions.

How to choose the right AI app for you

Do not download all 16. Match the app to what you actually do:

• Just want one app? Get ChatGPT.
• Write a lot? Add Claude and Grammarly.
• Student? Try NotebookLM, Perplexity, and Otter.ai.
• Love photos? Get Remini and Lensa.
• Want it free and built in? Turn on Apple Intelligence first.

Are AI apps safe to use?

The apps above are made by established companies and are safe for everyday use, but apply common sense:

• Stick to apps from real companies, like the ones in this list.
• Never share passwords, bank PINs, or sensitive secrets with a chatbot.
• Check the App Store privacy label to see what data each app collects.
• Skip random clone apps with no reviews or unclear developers.

Bottom line

AI apps genuinely save time every day, from drafting emails to restoring old photos to studying smarter. Our advice: start with ChatGPT and Apple Intelligence because both are free and immediately useful, add Claude or Perplexity if you write or research a lot, and only pay for the one app you reach for daily. Download a single pick from this list today and try it for a week — you will quickly see which one earns a permanent spot on your home screen.
