The Verdict
Brave Leo is the only AI assistant that guarantees your conversations aren’t stored, trained on, or linked to your identity. Built directly into the Brave browser, it summarizes pages, answers questions, and generates content — all with a privacy guarantee that no other AI chatbot matches. The free tier with Llama and Qwen models is surprisingly capable.
What It Does
Brave Leo is an AI chat assistant integrated into the Brave browser on desktop and mobile. It summarizes web pages, PDFs, and videos in the active tab, answers questions with web context, generates content, translates text, and writes code. Free users access Llama 3.1, Qwen 3, Claude Haiku 3.5, and GLM models. Premium subscribers get Claude Sonnet 4, DeepSeek R1, and Kimi K2.5.
What We Liked
- True privacy: No account required. Conversations are not stored, not used for training, and not linked to any identifier. Responses are proxied through anonymous servers.
- Page-aware: Leo can read and discuss the current web page, making it genuinely useful for research and reading.
- Multiple models: Access to Claude Sonnet, DeepSeek R1, Llama, and others — choose the best model for each task.
- Free tier works: The free models (Llama, Qwen, Claude Haiku) handle most daily tasks competently.
What We Didn’t Like
- Brave browser required: You must use Brave. No standalone app or integration with other browsers.
- No memory: Every conversation starts fresh. No persistent context, no saved preferences, no project-level knowledge.
- Premium price: $14.99/month for premium models is steep when ChatGPT Plus costs $20 with more features.
Pricing Breakdown
Free tier with Llama 3.1, Qwen 3, Claude Haiku 3.5, and GLM models. Leo Premium: $14.99/month for Claude Sonnet 4, DeepSeek R1, Kimi K2.5, higher rate limits, and priority access.
The Bottom Line
Brave Leo is the clear choice for anyone who wants AI assistance without surveillance. The privacy guarantee is genuine and unmatched. If you’re already using Brave or willing to switch, Leo adds meaningful AI capabilities at no cost — and the premium tier delivers frontier models without the data collection.
