AI open-source search engine
Provides AI‑enhanced web search that returns concise answers instead of raw links. The engine combines traditional crawling with a large language model to summarize results, reducing the need to click through multiple pages. Users can switch between Google, Bing, or DuckDuckGo back‑ends, and the system can also query local document collections when self‑hosted. Because the code is open source, developers can replace the default model with any compatible LLM, such as Llama‑2 or Mistral, to control cost and data handling. Privacy‑first design keeps queries on the host server, avoiding third‑party tracking. Designed for developers, researchers, and privacy‑concerned users who want a searchable interface without ads. The web UI offers a clean input box, instant answer pane, and optional source list for verification. A lightweight browser extension injects the same interface into any site, letting users ask follow‑up questions without leaving the page. Perplexica ships with Docker support, enabling one‑click deployment on local machines or cloud instances. The free license eliminates subscription fees, making it attractive for hobby projects and small teams. Compared with commercial AI search services, Perplexica provides full control over model choice and data retention. Supports multi‑language queries, markdown rendering of answers, and syntax highlighting for code snippets. Community plugins add features like PDF indexing, RSS feed crawling, and custom ranking algorithms. The project includes detailed documentation and a GitHub issue tracker for rapid troubleshooting. While the answer quality depends on the underlying LLM, the platform offers prompt‑engineering tools to improve relevance. Overall, Perplexica delivers a customizable, ad‑free AI search experience that can be run entirely on private infrastructure.
