Brave Search AI

Perplexity Spaces

Best overall

For everyday users who want a simple, all-in-one research assistant that can search the web, analyze uploaded files, and collaborate with others, Perplexity Spaces is the clear winner. Brave Search AI is a powerful privacy-focused search engine and API for developers, but it lacks a mobile app, a beginner-friendly interface, and the kind of interactive, document-aware workspace that non-technical people need. The single biggest difference: Perplexity Spaces feels like a smart research partner you can talk to and share files with, while Brave Search AI is more of a behind-the-scenes search tool for building other apps.

Completely private — no tracking of your searches, which is rare among search engines
Very affordable API for developers who want to build AI-powered search into their own apps
Integrates natively with the Brave browser's Leo AI sidebar for quick answers
No mobile app, so you can't use it conveniently on your phone
Not designed for everyday users — setup requires technical steps like generating API keys and writing code
Smaller search index than Google, so you might miss some local or niche results
Advanced AI features (like using Claude or Mistral) require a paid Leo Premium subscription

Perplexity Spaces: strengths & weaknesses

Real-time web search with clear citations, so you can fact-check answers easily
Lets you upload PDFs, images, and code files, then ask questions about them — great for students and professionals
Persistent 'Spaces' remember your conversation and files, so you don't have to repeat yourself
Collaborative features let you invite teammates to work on research together
Free tier is limited — you get a small number of 'Pro searches' and can only create a few Spaces
Occasionally makes factual errors on very specialized or niche topics, so you still need to double-check
No offline mode — you need an internet connection to use it
Advanced features like larger file uploads and team collaboration require a Pro subscription

Common questions

Is Brave Search AI better than Perplexity Spaces for privacy?

Yes, Brave Search AI is better for privacy because it has a strict zero-tracking policy for all searches. Perplexity Spaces does collect some usage data, though it doesn't sell it. If privacy is your top concern, Brave is the safer choice.

Can I use Perplexity Spaces on my phone?

Yes, Perplexity Spaces works well on a phone through its mobile website. There is no dedicated app, but the web interface is responsive and easy to use on a small screen. Brave Search AI has no mobile app and is awkward to use on a phone.

Which tool is easier for a non-technical person to start using?

Perplexity Spaces is much easier. You just create an account and start typing questions or uploading files. Brave Search AI requires you to install a browser, enable settings, and often use an API — it's not beginner-friendly.

Do I need to pay for either tool to get real value?

Perplexity Spaces gives you real value on the free tier, but you'll hit limits on searches and file uploads. The Pro plan ($20/month) unlocks the full experience. Brave Search AI's basic search is free and valuable for privacy, but its advanced AI features require a Leo Premium subscription.

Can I use these tools for team collaboration?

Only Perplexity Spaces supports team collaboration — you can invite teammates to shared Spaces. Brave Search AI has no collaboration features at all; it's a single-user search tool.

Which tool is better for writing a research paper?

Perplexity Spaces is far better for writing a research paper because you can upload your sources, ask the AI to summarize them, and get cited answers that you can verify. Brave Search AI is just a search engine — it won't help you organize or analyze your materials.

Perplexity Spaces wins for everyday users who need a versatile, easy-to-use research assistant; Brave Search AI is a powerful but developer-focused privacy search tool.

If you just want a smart, easy-to-use research assistant that works on your phone and can handle your PDFs, go with Perplexity Spaces. It's the tool you'll actually use every day. If you're a developer building something private and custom, or you're a privacy absolutist who already uses Brave, then Brave Search AI is a solid choice — but expect a steeper learning curve.
