2. You.com — AI‑Powered Search & Chat
You.com combines a search engine with an AI assistant, offering multiple model backends (GPT‑4, Claude, and others) depending on your query.

3. Google Gemini — Deep Workspace Integration
Google Gemini (gemini.google.com) gives you Gemini 3 Pro with full access to Google’s ecosystem. The free tier includes real‑time web browsing, image generation, and strong integration with Gmail, Docs, and Drive. No credit card needed.

4. Perplexity — AI Search with Citations
Perplexity (perplexity.ai) redefines search by providing concise answers backed by citations.

No signup required to start searching. It’s a must‑have for students and professionals who need verifiable sources.
5. Le Chat by Mistral — European Flagship
Mistral’s Le Chat (chat.mistral.ai) offers Mistral Large 2 and Pixtral vision capabilities at no cost. The interface is minimalist and fast.

DeepSeek (chat.deepseek.com) is a favorite among developers. Its V4 model and “reasoner” variant deliver strong coding performance and complex problem‑solving.

OpenRouter (openrouter.ai) is an API that lets you use models from OpenAI, Anthropic, Google, Meta, and many others with a single key.
