Brave launches privacy‑first AI assistant Leo
Brave has added Leo, a privacy‑first AI assistant that lives in the browser sidebar and does not log or store user inputs. The free tier ships with Meta’s Llama 3.1, Alibaba’s Qwen 3, Anthropic’s Claude Haiku 3.5 and GLM models, and works on Windows, macOS, Linux, Android and iOS.
Key points
- Brave Leo offers a privacy‑first AI assistant built into the browser, with no account or data logging.
- Free tier includes Llama 3.1, Qwen 3, Claude Haiku 3.5 and GLM models.
- Premium costs $14.99/month, giving access to Claude Sonnet 4, DeepSeek R1, Kimi K2.5 and higher rate limits.
Premium users pay $14.99 per month or $149.99 annually and gain access to Claude Sonnet 4, DeepSeek R1, Kimi K2.5 and higher rate limits, but the privacy model stays unchanged. Leo can read the active tab, PDFs, Google Docs, Sheets and YouTube transcripts, and it supports multi‑tab context, tab focus mode and a new skills feature. It also offers a local‑first summarization model, Brave Ocelot, and a bring‑your‑own‑model option.
The assistant is aimed at data professionals who need to work with proprietary or sensitive content without sending it to external servers, offering a privacy‑centric alternative to cloud‑based tools like Gemini, Perplexity and ChatGPT.
