Who should pick which
Pick ChatGPT for everyday drafting, Q&A and file analysis across web and mobile (Free: $0/month); think twice if you need guaranteed access to the strongest models without paying. Pick Claude for long-form writing, analysis and research with documents (Free: $0); think twice if you need unlimited heavy usage on a low budget. Pick Google Gemini for people already in Google's ecosystem (Gmail, Drive, Photos) (Free: $0/month); think twice if you don't use Google services and want a standalone assistant. Pick Le Chat (Mistral) for a European alternative assistant (Free: $0). Watch out: pro price not read reliably.
