Brave Leo Review 2026: Pricing, Features and Verdict

What it is

Leo is the AI assistant built into Brave, the Chromium based browser known for blocking ads and trackers by default. Brave launched Leo on desktop in November 2023 and brought it to Android and iOS, so it now runs everywhere Brave does: Windows, Mac, Linux, Android and iOS.

Leo opens in a side panel next to the page you are reading. You can ask it about the current page, a PDF, a Google Doc or Sheet open in a tab, or anything else, and it answers without you leaving the tab. It is a chat assistant first. Unlike Perplexity Comet, it does not click and type on websites by default.

Three things set it apart from the other AI browsers we cover:

• No account on the free tier. You can use Leo the minute you install Brave.
• A privacy design, not just a privacy policy. Brave strips IP addresses, uses unlinkable tokens for Premium and, since October 15, 2026, runs one model inside trusted execution environments with end to end encryption.
• Model choice. You pick the model per chat from a list that mixes open weight models with Anthropic's Claude, or you plug in your own.

Pricing explained

Leo has two tiers.

Plan	Price	What you get
Leo (free)	$0	Open weight models such as GPT OSS 20B, Llama 4 Scout and Maverick, Qwen 3 VL 30B; standard rate limits; no account
Leo Premium	$14.99 per month or $149.99 per year	Adds Claude Sonnet and Opus 4.6, DeepSeek v3.1, GPT OSS 120B, Mistral Large, Pixtral Large, Qwen 3 VL 235B, Qwen 3 Coder 480B; higher rate limits; early features

Prices are from Brave's premium page and the model lists from Brave's March 2026 Android release notes, in October 2026. Premium has a 7 day free trial. The yearly plan works out to about $12.50 a month, a 17% saving over monthly.

What the limits mean in practice. Brave does not publish message caps for either tier. Its Leo page says only that access can vary with traffic and that Premium gets higher limits. If you hit the free limit, you can switch to another free model or wait.

One subscription, several devices. Brave's Android and iOS launch posts say one Leo Premium subscription covers up to 5 devices across iOS, Android, Linux, macOS and Windows. That makes it cheap for a household with one subscriber.

Hidden costs. None in the subscription itself. Leo Premium is separate from Brave's other paid products: Brave VPN is $9.99 a month and Search Premium $3 a month, and the premium page does not list a bundle.

How it compares. At $14.99, Leo Premium costs less than Microsoft 365 Premium ($19.99), which is what Edge's agent requires, and less than Google AI Pro ($19.99) for Gemini in Chrome auto browse. See all assistant prices on the Price Index.

Key features

Page, PDF and document summaries

Leo reads the page in your current tab, including highlighted text, and can summarize it, answer questions about it or rewrite part of it. Brave lists PDFs, Google Docs and Google Sheets among the formats it reads. This is the feature most people use daily, and the free models handle it well enough for news articles and long docs.

Model picker

You choose a model per conversation. Free users get the smaller open weight models; Premium users get the full list, including Claude Opus 4.6 for harder writing and analysis and Qwen 3 Coder 480B for code. Brave says all models, Claude included, run through its own infrastructure, so your chats do not go to Anthropic under your name.

Encrypted chats on GLM 5.3 Flash

On October 15, 2026 Brave added end to end encryption for chats with GLM 5.3 Flash, an open weight model released under an MIT license in August 2026. The browser encrypts each prompt with Oblivious HTTP before it leaves your device, and only an attested trusted execution environment can decrypt it. The model can even call Brave Search from inside that environment. It is free for all users on Release, Beta and Nightly.

Bring Your Own Model

BYOM lets you point Leo at a local model running on your computer or at a remote endpoint you control. For developers and privacy purists, this means your prompts never touch Brave's servers at all.

AI browsing (experimental agent)

Brave announced AI browsing on December 10, 2025 in Nightly and moved it to all release channels on May 5, 2026 for early testing. You enable it in brave://flags, then start it from a button in Leo's input box. Brave's safeguards are the strictest we have seen in this category:

• It creates a brand new browser profile, so the agent has none of your cookies, logins or site data.
• An alignment checker model reviews each action against what you asked for.
• It will not open internal pages, non HTTPS sites or sites flagged as unsafe.
• It runs only when you start it.

The cost of that caution is convenience: the agent cannot use your signed in accounts, which is where most agent tasks happen.

Chat history and temporary chats

History is stored locally on your device, not in a cloud account, and you can turn it off or use temporary chats that leave no history.

What users say

Leo has no separate rating; it ships inside Brave. The Brave browser rates 4.8 on the US App Store from 665,330 ratings, among the highest of any browser, though those ratings cover the whole browser, not just Leo. Brave's AI browsing rollout drew a mixed response in privacy communities: some users welcomed the opt in, isolated design, others questioned whether a privacy browser should ship an agent at all. The limits most likely to frustrate you are on the published record: free models are smaller than ChatGPT or Claude, Brave does not publish message caps, and the agent sits behind a flag.

Privacy and security

This is Leo's strongest section. Per Brave's browser privacy policy and Leo page:

• Data sent: your prompt and conversation context; for summaries, the page content and any highlighted text; for tab features, titles and URLs of open non private tabs.
• Retention: Brave says it does not store or retain prompts, responses, context or personal data on its servers. Conversations are cached briefly and deleted within minutes.
• Training: Brave says it does not use your conversations for model training.
• Identity: no IP address collection on Leo requests; Premium uses unlinkable tokens so Brave cannot connect your purchase to your usage.
• Encryption: end to end encrypted chats with GLM 5.3 Flash through OHTTP and trusted execution environments since October 15, 2026.
• Agent safety: isolated profile, alignment checker and opt in only.

Brave has also published security research on other AI browsers, including prompt injection flaws in Perplexity Comet in 2025, and a June 2026 post calling indirect prompt injection a fundamental challenge for AI agents. That context explains why its own agent is gated.

Brave lists no SOC 2 report for Leo on these pages, and there is no business admin console for Leo.

Who it is for

• Privacy first users who want AI in the browser without an account or cloud history.
• Brave users already who want Claude Sonnet and Opus for $14.99 a month without a separate Claude subscription.
• Households that can share one Premium subscription across up to 5 devices.
• Developers who run local models and want them in a browser panel through BYOM.

Who should skip it

• People who want an agent that does tasks today. Comet and Gemini in Chrome act on sites by default; Leo's agent is a flag with no access to your logins.
• Chrome loyalists. Leo only exists inside Brave. If you will not switch, Gemini in Chrome is the free equivalent.
• Teams that need admin controls or a SOC 2 report. Brave lists neither for Leo.
• Heavy users who need published limits. Brave does not say how many messages you get.

Alternatives

• Perplexity Comet: free AI browser whose assistant takes actions on sites.
• Copilot in Edge: free for Windows users; agent with Microsoft 365 Premium.
• Gemini in Chrome: free chat in Chrome; auto browse on Google AI Pro.
• Dia and Opera Neon: newer AI first browsers.
• The full ranking is in best AI browsers.

Verdict

Brave Leo is the pick if privacy decides it. No account, no server side chat storage, no training on your chats, and now encrypted chats on one model put it ahead of every rival on data handling, and $14.99 a month for Claude inside the browser is fair. It loses on agent features: if you want a browser that books and buys for you, Leo is not there yet, and Brave is choosing caution on purpose.
