Best overall

NucliaDB

Brave Search AI wins for everyday users who want a private, ad-free search experience with AI answers built into their browser — it's simple and free. NucliaDB is a powerful developer tool for building custom AI search over your own files, but it's overkill for non-technical people. The single biggest difference: Brave Search AI is a ready-to-use search engine; NucliaDB is a database you have to build and code against.

Common questions

Can I use Brave Search AI on my phone?

Yes, but only through the Brave browser app on iOS or Android — there is no separate mobile app. You can enable 'Answer with AI' in the browser settings.

Is NucliaDB free?

The core software is open-source and free to run yourself, but you'll need technical skills to set it up. The cloud-hosted version (Progress Agentic RAG) charges based on usage, which can get expensive for large amounts of data.

Which tool is better for searching my personal documents?

NucliaDB is designed for that, but it's hard to use. For a non-technical person, a simpler tool like Google Drive search or a dedicated document scanner app would be better. Brave Search AI only searches the public web.

Does Brave Search AI work without the Brave browser?

You can use the search website (search.brave.com) in any browser, but the AI sidebar and deeper integration only work in the Brave browser.

Is Brave Search AI better than NucliaDB for a small business owner?

It depends on what you need. If you want private web search for research, Brave Search AI is better. If you want to build an AI that answers questions from your business files, you'd need a developer to set up NucliaDB — it's not a plug-and-play solution.

Brave Search AI wins for everyday users who want private, AI-powered web search with zero setup; NucliaDB is a developer-only tool for building custom AI over your own data.

For almost everyone reading this, Brave Search AI is the clear winner — it's free, private, and works instantly in your browser. NucliaDB is a powerful tool, but it's built for developers and requires serious technical effort. Start with Brave Search AI, and only look at NucliaDB if you have a specific need to search your own files and have a programmer on hand.
