Brave has spent a decade selling one idea: that a browser can be fast and private because it is not funded by watching you. Leo, its built-in assistant, is that argument applied to AI — and it is the most complete implementation of an in-browser assistant among the mainstream browsers, which makes it the right thing to review here rather than the ad blocker.
- No account or login needed to use the free assistant
- Brave states chats are not retained, not shared and not used for model training, with no linkable identifiers collected
- Summarises pages, PDFs, Google Docs and Sheets from the sidebar or the address bar
- Bring Your Own Model — connect a local model or a third-party API instead of Brave's
- Chat history stored locally on the device; temporary chats leave nothing behind
- Tab organisation gathers pages on a topic into a new window
- Leo Premium is $14.99 a month — the same price as subscribing to a frontier assistant directly
- The models are third-party (Anthropic, Meta, Mistral lineages); Brave adds the wrapper, not the intelligence
- Free-tier availability varies with traffic, and Brave says as much
- No agentic browsing — Leo reads and answers, it does not act on pages for you
- Brave's own FAQ confirms Leo hallucinates and advises double-checking every answer
- Privacy-minded users who want an assistant without handing a chat provider an account
- People who summarise long pages and PDFs constantly
- Anyone running a local model who wants a browser front end for it
- You already pay for ChatGPT, Claude or Gemini — you are buying the same models twice
- You need an agent that fills forms and completes tasks, not a reader
- Switching browsers would cost you extensions or workflows you depend on
Pricing
The browser plus the free Leo assistant. No account required; rate limits vary with traffic.
Access to more models, higher rate limits and early access to new features, with a 7-day free trial. Prices as listed on brave.com in August 2026.
A paid, stripped-back build of the browser centred on Shields, with most other features removable. Activates across your devices.
Sold separately from Leo; none of them are required to use the assistant.
What Leo does
You reach it by typing in the address bar and choosing "Ask Leo", or by clicking the Leo icon in the toolbar or sidebar. From there it will summarise the page you are on, answer questions about it, translate it, analyse a PDF or a Google Doc or Sheet you have open, draft text, and suggest code. Brave Search results feed into answers so that current events do not fall off a training cutoff.
Two smaller features are worth more than they sound. Tab organisation will gather everything you have open on a topic and move it into its own window — a real fix for a real problem. And temporary chats leave nothing in history at all, which is the AI equivalent of a private window and the sort of detail Brave notices because it is the whole company's instinct.
Chat history, when you keep it, is stored locally on the device and readable from the sidebar or the full-page view at brave://leo-ai.
The privacy claims, stated precisely
Brave's documentation is unusually specific, so it is worth quoting the shape of it rather than paraphrasing into mush. Leo does not require an account or login. Brave says conversations are not retained or shared and are not used for additional model training. It says no identifiers that can be linked to you are collected, including IP address, and no personal data is retained. Premium subscribers do need an account, but Brave states it exists purely to verify entitlement and is unlinkable to Leo usage.
That is a stronger set of commitments than any other browser assistant makes, and it is the actual product. The models are not Brave's.
Someone else's models, wrapped
Leo routes to third-party models — Brave's own documentation names the Mixtral, Claude and Llama families, with specific versions shown in the interface. Brave is doing integration, privacy engineering and rate management. That is valuable work, and it is not the same as building the intelligence.
Which brings us to the price. Leo AI Premium is $14.99 a month, or $149.99 a year, with a seven-day trial. That is at or above the going rate for a direct subscription to a frontier assistant, and a direct subscription gets you the provider's full product — its file handling, its projects, its apps, its newest models on day one — rather than a browser sidebar with rate limits.
The counter-argument is coherent: you are paying for the wrapper, deliberately, because the wrapper is what keeps a chat provider from building a profile of your questions. If that is genuinely worth fifteen dollars a month to you, this is the only product that sells it. Most people will find the free tier sufficient and should stay there.
Bring Your Own Model
The feature that most justifies Brave's existence in this category is BYOM: point Leo at a model you run locally, or at a remote endpoint or third-party API, and use the browser as a front end. For anyone running a local model on their own hardware, this closes the loop — a capable assistant, in the browser, with nothing leaving the machine at all. No other mainstream browser offers it.
What it cannot do
Leo reads; it does not act. There is no agentic browsing, no filling in a checkout, no multi-step task execution across tabs. That is the frontier every other AI browser is racing toward, and Brave is not currently in that race.
It also hallucinates, which Brave says outright in its own FAQ along with advice to verify answers — including by running the same query through Brave Search. That honesty is refreshing and does not change the underlying limitation.
The rest of the price list
Brave sells its premium features separately rather than as one bundle: VPN at $9.99 a month or $99.99 a year, Search premium at $3.00 a month, Talk premium at $7.00 a month, and Brave Origin, a one-off $59.99 purchase for a stripped-down browser build centred on Shields. None of it is required to use Leo, and the unbundling is welcome — you are not paying for a VPN to get an assistant.
Against the AI-first browsers
The interesting comparison for Brave is no longer Chrome. It is the newer browsers built entirely around an assistant, where the AI is the interface rather than a panel beside it — agentic browsing, automated multi-step tasks, the browser doing the clicking.
Brave is not competing there and does not appear to want to. Leo is deliberately a reader and a responder: it summarises, explains, translates and drafts, and it does not touch the page on your behalf. For anyone nervous about an autonomous agent with access to their logged-in sessions, that restraint is a feature — the attack surface of an assistant that cannot act is dramatically smaller than one that can.
The risk is being outflanked. If agentic browsing turns out to be genuinely useful rather than a demo, a privacy-first browser that refuses to do it will look principled and dated at the same time. Brave has been in that position before, on advertising, and has generally been comfortable there.
The verdict
Install Brave, use free Leo, and enjoy the best no-account, no-retention browser assistant currently shipping. Pay for Premium only if the rate limits are genuinely obstructing you and you have decided the privacy wrapper is worth paying a frontier-assistant price for. And if you are technical, look hard at Bring Your Own Model — it is the feature here with no real competitor.
