AI Assistants
Chat apps like ChatGPT, Claude and Gemini that you use directly.
ChatGPT
Free / Plus $20/mo“Still the safest default for most people. It does the widest range of things well, and the free tier now has unlimited text chats. Plus at $20 a month is where it gets genuinely good.”
Claude
Free / from $17/mo“The best writer and the best coder of the big assistants. Pro at $20 a month includes Claude Code, which makes it the obvious pick if you write software or long documents.”
DeepSeek
Free“The strongest open-weights option, and almost free to call through the API. Developers should try it. Read the privacy policy before you put anything sensitive into the hosted app.”
Gemini
Free / from $4.99/mo“The best value if you already pay Google for storage. AI Pro at $19.99 gets you Gemini 4 Argon, 5 TB of storage and video generation, and the Gmail, Docs and Android integration is unmatched.”
Grok
Free / SuperGrok $30/mo“Unbeatable for what's happening right now, thanks to live X data. It's a capable all-rounder too, but pick it for real-time news and trends rather than as your only assistant.”
Meta AI
Free“The AI you already have if you use WhatsApp or Instagram. Great for quick answers and free images inside your chats, but most people will want a dedicated assistant for serious work.”
Microsoft Copilot
Free / from $9.99/mo“Worth it if you already pay for Microsoft 365. Copilot inside Word and Excel saves real time, but as a standalone chatbot it trails ChatGPT, Claude and Gemini.”
Mistral Vibe (formerly Le Chat)
Free / from $14.99/mo“The European pick. It's cheaper than the US big three at $14.99, includes API credits, and is the only one here you can deploy on your own servers.”
Perplexity
Free / from $17/mo“The best AI for research you need to check. Every answer cites its sources, and one subscription gets you models from OpenAI, Anthropic, Google and xAI.”
