Pick one general assistant and use it for two weeks on real errands before judging. ChatGPT is the widest: chat, images, voice and agents in one app, and the one most people already use (44% of US adults in Pew's 2026 survey). Claude is the careful writer, strong on long documents and analysis. Gemini suits you if you live in Gmail, Docs and Android. Copilot works inside Word and Excel, Meta AI inside WhatsApp, Perplexity answers with sources you can check, and Grok reads what people are posting on X. For low-stakes questions any free tier is fine. For real work, Ethan Mollick's July 2026 guide still points to ChatGPT or Claude.
