Short answer: ChatGPT is still the most popular AI tool and the best all-rounder, but it is no longer the only serious choice. For some tasks, it isn't the best one.

Still the Biggest
ChatGPT reached 900 million weekly users in February 2026, and OpenAI later confirmed it had passed 1 billion weekly users. For most people, "AI chatbot" still means ChatGPT. Reviewers often rank it best overall because of its flexibility, multimodal features and wide ecosystem.
But the Gap Has Closed
The old rule of thumb said ChatGPT codes, Gemini searches and Claude writes. In 2026 that no longer holds, because the main rivals now compete head-on:
- ChatGPT (OpenAI): best for general use, brainstorming, and image and video generation.
- Claude (Anthropic): often rated strongest at coding, and praised for natural writing and long documents.
- Gemini (Google): strong at multimodal work and long context, and ideal for Google Workspace users.
- Perplexity: a leading choice for research, built around live, cited search.
Comparisons like this one reach the same conclusion: there is no universal champion.
Price and Access
At the top end, the big three are level: each charges about $20 a month for its standard paid plan. What differs is the extras. Gemini's plan bundles 2TB of Google storage and Workspace integration, and its free tier is widely considered the most generous. OpenAI has also introduced ChatGPT Go at $8 a month in 171 countries, which makes paid AI far more affordable in price-sensitive markets.
Which Should You Pick?
- Everyday use, brainstorming, images: ChatGPT
- Coding, long reports, polished writing: Claude
- Google Docs, Gmail, large files and video: Gemini
- Fact-finding with sources: Perplexity
The Verdict
Is ChatGPT still the best AI tool in 2026? For the average person who wants one tool that does most things well, yes. But no single tool wins every category, and the best AI is the one that fits your task. Many power users now keep two: a general assistant and a specialist. Before paying for anything, test the free versions on your own real work.
