LisLoi is an open-source search engine and information portal focused on Belgian law. It helps users explore legislation, including laws, decrees and orders, as well as court decisions and parliamentary proceedings. The service brings these legal resources together with search tools and features such as bookmarks, RSS feeds and a classic version that can be used without JavaScript.

LisLoi also offers an AI-powered legal chatbot, where users can ask questions about Belgian legislation and select from general or specialist areas, including tax, employment, company, property, family, migration, consumer, criminal, social security, administrative and privacy law. The chatbot is presented as an information aid rather than official legal advice, and the site warns that AI-generated responses may be inaccurate. Conversation history is optional; users can choose browser-based encryption with a storage password or standard server storage, and can delete saved history.

The portal is part of a multilingual family of sites, with related services in Dutch, German and English. LisLoi provides free and paid options, including professional features
