ChatGPT alternatives and AI assistants compared — free tiers, limits and real test results.
AI chatbots are the most-used AI tools on the planet, and the gap between the best and the rest is wider than marketing suggests. In our hands-on tests, Claude writes the most natural prose, ChatGPT remains the best all-rounder thanks to browsing, image generation and custom GPTs, Gemini wins for Google Workspace users, and DeepSeek is the standout free option with genuinely open weights. Perplexity is our pick when you need answers with real citations.
Free tiers matter more than most people realise. ChatGPT's free plan throttles at peak times, Claude's free tier has strict daily caps, while DeepSeek and Microsoft Copilot are generous enough for daily use. Before paying $20 a month, run your real tasks on two or three free tiers side by side — most people only need one subscription, and our comparison table above shows exactly where each chatbot wins and where it falls short.
We signed up for each tool's free tier, ran identical test tasks, and ranked them on output quality, ease of use, pricing fairness and free-tier generosity. Prices change often — always confirm on the official site before buying.
