What is Fireplexity?
Fireplexity is a production-ready, open-source application that empowers you to move beyond simple search results. Built for developers, it provides the complete framework to create a custom AI-powered answer engine that delivers direct, accurate answers with verifiable citations, tailored to any niche or internal knowledge base.
Key Features
Fireplexity is engineered to provide a robust foundation for your custom search applications. Here are the core capabilities that make it possible:
🌐 Real-Time Web Intelligence: Fireplexity doesn't just perform a keyword search. It leverages the powerful Firecrawl API to reliably scrape and render web content, including JavaScript-heavy sites. Its intelligent algorithms then score and select the most relevant information to form the basis of a truly informed answer.
🧠 Streaming AI Synthesis with Citations: Get answers generated in real-time. Fireplexity uses GPT-4o-mini (by default) to synthesize information into a coherent response, streaming the text directly to your user. Crucially, every claim is backed by interactive, inline citations, so users can instantly hover and preview the source for complete transparency.
🔧 Full Open-Source Control: As a Next.js 15 application, Fireplexity gives you complete control over the code. There's no vendor lock-in. You can customize the user interface, swap the AI model for any OpenAI-compatible endpoint, and extend the functionality to meet your specific needs.
🚀 Rapid, Production-Ready Deployment: Fireplexity was built to be deployed, not just demonstrated. With a straightforward setup process, you can have your own answer engine up and running in minutes. Just clone the repository, add your API keys, and launch.
How Fireplexity Solves Your Problems:
Stop waiting for a one-size-fits-all solution. Fireplexity provides the toolkit to build precisely what you need.
Create a Powerful Internal Knowledge Base: Connect Fireplexity to your company's internal documentation or private web content. You can provide your team with an internal search tool that gives direct, cited answers to complex questions, dramatically speeding up access to information.
Develop a Specialized Research Tool: Are you an expert in a specific field like finance, law, or scientific research? Use Fireplexity to build a public or private answer engine that focuses exclusively on trusted sources within your domain, providing unparalleled accuracy for specialized queries.
Build a Niche Community Resource: Power a Q&A site for any hobby or community, from gaming and cooking to programming and history. Offer users a superior experience by providing instant, synthesized answers drawn from a curated set of community-approved websites, forums, and blogs.
