I tested a dozen AI assistants to find the best Brave Leo alternatives in 2025

Brave Leo is a popular pick if you want an AI assistant built right into your browser, especially with its big focus on privacy. But with new AI tools popping up constantly, you're probably wondering what else is out there. Maybe you need something with a bit more muscle, an assistant that can help your whole team, or even tighter privacy than what a browser can offer.

The hunt for the right AI tool can feel like you're constantly having to choose between privacy and power. To help you find a good balance, I dug into the world of Brave Leo alternatives to see which ones are actually worth your time in 2025. This guide will walk you through my top choices for everything from personal research to professional customer support.

Understanding AI assistants

At their core, these tools are designed to make your life online just a little bit easier. They’re not just search engines; they're woven directly into what you’re doing to help you understand, summarize, and create things. Think of them as a smart sidekick that can:

• Summarize a super long article or YouTube video in seconds.

• Answer questions about whatever you're looking at on your screen.

• Whip up some text, like a draft for an email or a social media post.

• Handle tasks for you, like filling out forms or comparing products (you'll sometimes hear these called "agentic" skills).

Brave Leo is a classic example of this, living inside the Brave browser and promising not to use your chats to train its AI models. That privacy angle is a huge draw. But the idea of an "AI assistant" is getting bigger than just the browser. Now you can find alternatives built not just for you, but for your entire company, helping with things like answering customer support tickets or acting as your team's internal encyclopedia.

How I picked the best Brave Leo alternatives

To make a fair comparison, I judged each tool on four things that really matter when you're looking for something like Leo.

• Privacy and security: How do they handle your data? I looked for clear privacy policies, whether they use your conversations for training, and if your data is kept anonymous. This is the main reason people use Brave Leo, so any alternative has to have a good story here.

• Core features: Can it do more than just chat? I looked at how well it summarizes, generates content, and whether it has any of those "agentic" features that can actually perform tasks for you.

• Who it's for: Is this a tool for one person or a whole team? What you need for personal research is totally different from what a growing business needs for customer support. I figured out the ideal user for each one.

• Price and accessibility: Is it free? Is there a free trial? Or is it a full-on subscription? I checked for clear pricing and whether you could get started without having to schedule a demo with a sales team.

The 5 best Brave Leo alternatives in 2025

Alright, let's get into the details. Here’s a full breakdown of the best alternatives, each fitting a different need.

1. eesel AI

Brave Leo is great for you, but what happens when your entire team needs that kind of AI help? That's where eesel AI steps in. It’s an AI platform built for customer service and internal support, essentially becoming a secure, central brain for all your company’s knowledge.

Instead of just summarizing web pages, eesel AI plugs into your help desk (like Zendesk or Intercom), internal wikis (Confluence or Notion), and chat tools (Slack or MS Teams). It reads through your past support tickets and internal docs to handle frontline support, draft replies for your agents, and answer questions your team asks internally.

It takes that privacy-first idea from Brave and applies it to a business setting. Your data is yours alone; it’s never used to train general AI models. The best part? You can get it up and running in a few minutes by yourself, which is almost unheard of for business AI tools.

• Pros:

  • Super easy to set up on your own.

  • Brings all your company knowledge together, not just what's on the web.

  • Has a neat simulation mode to test the AI on old tickets before you let it talk to customers.

• Cons:

  • It's built for businesses, so it's not a tool for general web browsing.

  • It's a subscription service, so it's not a freebie for personal use.

• Pricing: You can try eesel AI free for 7 days. The Team plan is $299 per month, and the Business plan is $799 per month, which lets you train the AI on your past support tickets.

2. Perplexity

If you mostly use an AI assistant to find accurate, verifiable info, Perplexity is the one for you. It calls itself a "conversational answer engine," and for good reason. Its killer feature is that every single answer comes with footnotes linking back to the sources it used.

This is a huge deal for students, writers, and anyone who needs to actually back up their claims instead of just blindly trusting an AI. The free version is plenty powerful, and you don't even need an account to use it. While its privacy policy is more standard, it’s a fantastic choice for anyone who puts accuracy above all else.

• Pros:

  • It shows its work by citing sources for every answer.

  • Amazing for digging into new topics and doing research.

  • The free tier is very generous.

• Cons:

  • Not really built for creative writing or brainstorming.

  • Its privacy model is more about trusting the company than technical guarantees.

• Pricing: Perplexity has a free version with daily limits. The Pro plan costs $20 a month and gets you access to more powerful AI models and unlimited searches.

3. DuckDuckGo AI Chat

DuckDuckGo is all about privacy, and its AI Chat follows the same script. It basically works as an anonymous middleman between you and popular AI models from Anthropic (Claude), Meta (Llama), and others.

When you ask a question, DuckDuckGo sends it to the AI model for you, but it strips out all your personal info, like your IP address. This means you get to use some of the most powerful AIs out there without making an account or giving them your identity. It’s probably the closest thing to Brave Leo in spirit, giving you a simple, private way to get quick answers.

• Pros:

  • Strong privacy protection since all requests are anonymized.

  • Gives you free access to several top-tier AI models.

  • No account or login needed. Just go.

• Cons:

  • It’s just for chatting; it can't perform tasks for you.

  • It doesn't save your conversation history.

• Pricing: DuckDuckGo AI Chat is free. They've mentioned a paid plan might be coming to unlock even more advanced models, but there's no public pricing for that yet.

4. Microsoft Copilot

If you're already deep in the Windows and Microsoft 365 ecosystem, Copilot just makes sense. It’s built directly into the Edge browser, the Windows operating system, and all the Microsoft 365 apps. This lets it do things other assistants can't, like summarize a Word document you have open or draft an email in Outlook based on your calendar.

It uses GPT-4 and Bing search, so its answers are usually up-to-date and pretty detailed. Microsoft definitely collects more data than Brave, but if you're using a business account, you get some strong security controls. For getting work done inside the Microsoft bubble, its deep integration is tough to beat.

• Pros:

  • Seamlessly integrated with Windows and Microsoft 365.

  • Powered by GPT-4 with real-time access to search results.

  • Excellent for work-related tasks.

• Cons:

  • Not the best choice if you're a privacy hawk.

  • Can feel a bit much if you don't use Microsoft products.

• Pricing: The standard version of Copilot is free. Copilot Pro is $20 per month for priority access. Business plans have custom pricing.

5. Local LLMs (via Ollama)

For anyone who believes the only private data is data that never leaves your computer, running a local large language model (LLM) is the final frontier. Tools like Ollama have made it surprisingly easy to download and run open-source models (like Llama 3) right on your own machine.

With this setup, you have 100% privacy and control. No company can ever see your conversations. The catch? You need a decent computer (a good graphics card helps a lot), and the models are often a small step behind the big commercial ones like GPT-4. But for truly sensitive work, you can't get any more secure than this.

• Pros:

  • Complete and total data privacy.

  • You're not relying on any third-party servers or companies.

  • It's completely free, other than the cost of your computer.

• Cons:

  • You need to be a little tech-savvy to get it running.

  • Requires a powerful computer for good performance.

  • The models aren't quite as capable as the top paid options.

• Pricing: The Ollama software is free and open-source. You just have to bring your own hardware.

How to choose the right Brave Leo alternatives for you

So, how do you pick one? It really just boils down to what you need it for. Ask yourself a couple of questions to find the right fit.

1. Is this for me, or for my team?

   • Just for you: Perplexity, DuckDuckGo AI Chat, or a Local LLM are all solid choices for personal use.

   • For the team: eesel AI is built specifically for business needs like customer support and managing internal knowledge.

2. What’s my number one priority?

   • Extreme Privacy: A Local LLM is your only real choice.

   • Easy Privacy: DuckDuckGo AI Chat and Brave Leo are your best bets.

   • Accuracy: Perplexity wins this hands down.

   • Getting Work Done: Microsoft Copilot (if you're a Microsoft user) and eesel AI (for support teams) are built for this.

3. How much setup work am I willing to do?

   • None, please: DuckDuckGo AI Chat and Perplexity work right out of the box.

   • A little: eesel AI has a simple, self-serve setup for businesses that takes just a few minutes.

   • I don't mind getting my hands dirty: Setting up a Local LLM means getting comfortable with the command line.

Choosing the right Brave Leo alternative

The search for the best Brave Leo alternatives makes one thing clear: there's no single "perfect" AI assistant, but there is one that's perfect for you. If you're just looking for a private and convenient tool for yourself, options like DuckDuckGo AI Chat are fantastic. If you're a researcher, Perplexity's cited answers are a lifesaver.

But if you’re trying to use AI to help your business, your needs are different. You need a tool that respects your company’s data, fits into how you already work, and actually solves business problems. While browser assistants are great for personal productivity, a dedicated platform like eesel AI is the answer for teams who want to automate support and build a knowledge base that actually works.
