Which AI assistant is best in 2026?▾
It depends on what you optimise for. Claude Pro ($20/mo) for default-private and Claude Code; ChatGPT Plus ($20/mo) for the broadest tooling; Google AI Pro ($19.99/mo) for Workspace integration; Perplexity Pro ($20/mo) for multi-model + citation-backed search; Mistral Le Chat Pro ($14.99/mo) for EU jurisdiction and the cheapest premium tier. The four major US-based assistants are within $0.01 of each other at the entry premium tier.
Do AI assistants train on my chats?▾
It varies. Anthropic's Claude does not train on consumer Pro / Max inputs by default (per anthropic.com/legal/privacy). OpenAI's ChatGPT consumer accounts default to training on user inputs with documented opt-out in Settings → Data Controls. Google's Gemini training-data policy is more nuanced and Google Workspace context shifts the rules. Perplexity does not train on user data by default. Mistral has its own policy — review at mistral.ai before assuming.
Is ChatGPT Plus worth the upgrade from Free?▾
Plus at $20/mo lifts most usage caps, gives access to the latest GPT-5.2 + reasoning models, and unlocks Codex (coding), Sora (video), and image generation at higher quality. The Free tier remains generous in 2026 but caps quickly on heavier use. The $100/mo Pro tier launched in April 2026 sits between Plus and the existing $200/mo Pro for users who want higher usage without the full Pro $200 tier.
Why is Perplexity Pro different from Claude Pro and ChatGPT Plus?▾
Perplexity is a search-first assistant, not a model lab. Pro $20/mo bundles access to GPT-5.2, Claude Sonnet 4.5, Gemini 3 Pro, and Perplexity's own Sonar models — switchable per query. The four big assistants only expose their own underlying model. If you want one subscription that lets you compare answers across model labs, Perplexity is the only mainstream consumer option.
What is the EU AI Act and does it affect which AI I should use?▾
The EU AI Act (in force as of August 2024) categorises AI systems by risk and imposes obligations on providers offering services in the EU. It does not prohibit any of the consumer assistants in this comparison from operating in Europe; it does require additional disclosure, transparency, and risk-management procedures from providers above certain capability thresholds. Mistral, as an EU-headquartered company, has a structural alignment with the framework that the US-headquartered assistants do not. For consumer use the practical impact is small.
Can I run an AI assistant locally?▾
Yes, but the trade-off is real. Mistral releases open-weight models (Mistral 7B, Mixtral 8x7B, Mistral Small) under Apache 2.0 that can run on a workstation. Meta's Llama line is similarly open. Quality lags the closed flagships (GPT-5.2, Claude Sonnet 4.5, Gemini 3 Pro) but the privacy gain is total — no cloud round-trip, no policy to read. Tools: Ollama, LM Studio, llama.cpp.
