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.\n\nPremium 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.\n\nThe 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.","keyPoints":["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."],"whyItMatters":"Brave Leo gives data professionals a privacy‑centric alternative to cloud‑based assistants, reducing risk of exposing proprietary content while still accessing frontier models.","category":{"slug":"agents","name":"Agents & Tools","url":"https://digestai.news/category/agents"},"entities":{"companies":["Brave","Google","Perplexity","Meta","Alibaba","Anthropic"],"models":["Llama 3.1","Qwen 3","Claude Haiku 3.5","Claude Sonnet 4","DeepSeek R1","Kimi K2.5"],"people":[]},"firstPublishedAt":"2026-09-22T14:00:29Z","updatedAt":"2026-09-22T14:00:29Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"KDnuggets","title":"Bravely AI Browsing with Leo","url":"https://kdnuggets.com/bravely-ai-browsing-with-leo","publishedAt":"2026-09-22T14:00:29Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":null,"cite":{"text":"Digest AI, \"Brave launches privacy‑first AI assistant Leo\", 22 September 2026, https://digestai.news/story/brave-launches-privacyfirst-ai-assistant-leo","publisher":"Digest AI","title":"Brave launches privacy‑first AI assistant Leo","datePublished":"2026-09-22T14:00:29Z","url":"https://digestai.news/story/brave-launches-privacyfirst-ai-assistant-leo"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
