Perplexica: The Open-Source Alternative to Perplexity AI That Redefines Web Search

An AI-Powered Search Engine Combining Metasearch, Local LLMs, and Full Privacy

For years, web search has been dominated by tech giants prioritizing data collection and algorithm-driven personalization. Perplexica, a new open-source project, aims to disrupt this landscape by offering an AI-powered search engine focused on accuracy, transparency, and privacy.

Inspired by Perplexity AI, Perplexica doesn’t just search the web—it understands queries, leveraging advanced AI models to deliver precise, well-referenced answers. As an open-source and fully customizable platform, it provides users and developers with greater control over their search experience without relying on centralized services.

A Technical Architecture Built for Efficiency and Security

Unlike traditional search engines that rely on web crawlers and proprietary databases, Perplexica utilizes SearxNG, a metasearch engine that aggregates results from multiple sources without tracking users. It also integrates local large language models (LLMs) like Llama3 and Mixtral, allowing searches to be processed without sending data to external servers like OpenAI or Google.

This hybrid approach enables similarity-based search and embeddings, refining search results while ensuring data privacy.

Key technical advantages include:

• AI-Powered Query Processing – Generates and refines search queries for more relevant results.
• Optimized Information Retrieval – Uses embeddings to rank sources based on contextual relevance.
• Multiple Search Modes – Tailors results to different types of queries.
• API Integration – Supports OpenAI, Anthropic, Groq, and other AI providers.
• Docker-Based Deployment – Ensures fast installation and modular configuration.

Advanced Search Modes for a Smarter Experience

Perplexica introduces specialized search modes, enhancing search efficiency based on user intent:

• Standard Mode – Traditional web search with AI-powered query refinement.
• Copilot Mode (in development) – Generates multiple alternative queries to improve result accuracy, similar to Perplexity AI’s expansion feature.
• Academic Search Mode – Retrieves scholarly articles and research papers.
• Wolfram Alpha Mode – Processes mathematical and data-driven queries.
• YouTube Search Mode – Finds relevant videos based on user queries.
• Reddit Search Mode – Extracts discussions and opinions from Reddit.
• Writing Assistant Mode – Helps generate text without requiring web searches.

This modular approach allows Perplexica to adapt to different search needs without requiring extensive customization or training.

Privacy by Design: No Tracking, No Data Storage

One of Perplexica’s biggest advantages over AI-driven search engines like Bing AI or Google Bard is its strict commitment to privacy. While other services store user interactions for personalization, Perplexica does not log searches or collect user data.

Thanks to its SearxNG-based implementation and the ability to run local LLMs, users can search with complete anonymity, without the risk of being tracked or profiled.

Security-focused features include:

• Local AI model execution – No cloud-based processing required.
• No search history storage – Ensures full anonymity.
• VPN and proxy compatibility – Supports private browsing environments.

This open-source and privacy-first philosophy makes Perplexica an ideal solution for researchers, journalists, and privacy-conscious users.

Deployment & Installation: Flexible, API-Ready, and Docker-Compatible

To maximize accessibility, Perplexica can be deployed both locally and on remote servers.

1. Installation with Docker (Recommended)

Using Docker enables a quick and efficient setup with automated configuration.

Docker Installation Steps

1. Clone the official repository: git clone https://github.com/ItzCrazyKns/Perplexica.git
2. Navigate to the project directory and set up the environment file: mv sample.config.toml config.toml
3. (Optional) Configure API keys for OpenAI, Anthropic, or other providers.
4. Start the service: docker-compose up -d
5. Access the web interface at http://localhost:3000.

2. Using Perplexica as a Default Search Engine

Users can integrate Perplexica into their browsers as an alternative to Google or Bing.

1. Open browser settings.
2. Navigate to the ‘Search Engines’ section.
3. Add a new search engine with the following URL: http://localhost:3000/?q=%s
4. Set Perplexica as the default search engine.

3. API Integration

Developers can use Perplexica’s API to embed its search capabilities into applications or AI assistants.

Example API query:

curl -X GET "http://localhost:3000/api/search?q=artificial+intelligence"

Looking Ahead: Future Roadmap and Upcoming Features

The Perplexica development team is working on several upcoming enhancements:

• Finalization of Copilot Mode for more advanced AI-driven search refinement.
• Optional search history feature (without compromising privacy).
• Expanded support for additional local LLMs like Mistral and Falcon.
• Integration with decentralized storage services.
• Enhanced focus modes for better search adaptability.

There are also plans to introduce semantic search capabilities, similar to ChatGPT Browsing Mode and Arc Search AI.

Conclusion: A Strong, Evolving Open-Source Search Alternative

Perplexica represents the next evolution of AI-powered search engines, combining accuracy, privacy, and flexibility into an entirely open-source platform.

Its ability to run local AI models, integrate with external tools, and operate without storing user data makes it an attractive choice for those seeking full control over their search experience.

As AI continues to transform how we access information, projects like Perplexica prove that advanced search engines can be both powerful and privacy-friendly.
