What is AI Mode?
AI Mode is a dedicated tab in Google Search — sitting next to All, Images, and Videos — where you can ask a multi-sentence question and get a synthesized, conversational answer. Behind the scenes, Google breaks your query into sub-questions using a technique it calls query fan-out, runs them in parallel across its index, then has a custom Gemini model reason across the results (Google blog, March 2025).
After answering, AI Mode keeps the context. You can ask follow-up questions, attach images, or push deeper — much like talking to ChatGPT, Claude, or Perplexity. The big difference: you never chose Gemini. Google did.

AI Mode debuts in Labs
Google opens an experimental 'AI Mode' tab in Search Labs to Google One AI Premium subscribers, powered by a custom Gemini 2.0 model with query fan-out and multi-step reasoning. blog.google — AI Mode in Search

AI Mode vs. AI Overviews: what's the difference?
They're both Gemini-powered, but they behave very differently. AI Overviews appear automatically above organic results for eligible queries — a passive experience. AI Mode is a place you go to, a chat you open. Google itself describes AI Mode as having "more advanced reasoning and multimodality" than AI Overviews (Google's own whitepaper).
| Dimension | AI Mode | AI Overviews |
|---|---|---|
| Activation | Dedicated tab; opt-in per query | Auto-injected above organic results |
| Underlying model | Custom Gemini (fan-out + reasoning) | Lighter Gemini summarizer |
| Interaction | Multi-turn chat with follow-ups | Single synthesized answer |
| Source links | Inline citations + side panel | Collapsed citation chips |
| Your choice of model | No — Gemini only | No — Gemini only |
Is AI Mode private? Is it accurate?
Short answer: less than a classic search, and "usually, but check sources." AI Mode sends your full conversational context — not just a keyword — to Google's model servers. Brave's research team has warned that generative search UIs can leak more metadata than classic search when not carefully sandboxed (Brave research). Independent tests have also shown AI Mode hallucinating citations on medical and legal queries — a well-documented pattern across every single-model chat interface.
And because AI Mode only uses Gemini, its hallucinations are correlated — one weakness becomes every user's weakness. This is the core case for a multi-model workflow: asking Gemini, then GPT-5, then Claude the same question and comparing answers.
Stop trusting one model by default.
The multi-model alternative to AI Mode
ZeroTwo is built around a simple idea: you should pick which AI answers your question. Not Google, not OpenAI, not Anthropic. You.
- — 60+ models in one app — GPT-5, Claude Sonnet 4.5, Gemini 3 Pro, Grok 4, Perplexity, DeepSeek, Mistral, Llama, Kimi, and more.
- — Route by task — coding to Claude, research to Perplexity, brainstorming to GPT-5, real-time news to Grok. See the AI chat overview.
- — Not tied to one index — unlike AI Mode, ZeroTwo isn't a front-end for a single search graph.
- — One subscription, instead of paying for Gemini Advanced, ChatGPT Plus, and Claude Pro separately (compare pricing).
AI Mode is a strong product. It's also a single vendor's strong product. If you do serious work with AI — research, writing, coding — depending on one model is a risk you don't need to take.
