Chancery Lane Project launches AI-friendly WordPress plugin

The Chancery Lane Project has launched an open-source WordPress plugin that serves websites in a simplified format for AI systems. The UK nonprofit said the tool is intended to reduce data processing and energy use.

The plugin detects visits from known AI agents and large language model browsers, then delivers a stripped-down Markdown version of a page instead of the full HTML. This gives AI systems the main content without navigation menus, scripts, and other elements designed for human browsing.

The software is free to use and can be adapted by other organisations. TCLP developed it initially for its own library of climate-focused contract clauses and legal guidance, which it says is used in more than 110 countries.

The launch comes as organisations consider how online content is read not only by people but also by AI tools used for search, research, drafting, and analysis. Websites are generally built as rich visual pages for human users, but AI systems often have to process those same pages in full before extracting the core text.

TCLP said this creates extra computational work and higher token use, raising energy demand. Early testing of the plugin showed reductions of up to 90% in token usage, according to the organisation.

The Chancery Lane Project is best known for publishing contract clauses intended to help lawyers and businesses address climate risks and emissions through legal agreements. It says it has published almost 200 climate clauses through work involving 3,600 professionals across 113 countries.

The new tool widens that work into the design of digital information systems. TCLP said the aim is to keep legal knowledge accessible as AI becomes a more common route to professional information.

Ben Metz, executive director of The Chancery Lane Project, outlined that rationale in comments accompanying the launch. “If climate action scales through law, then ensuring that legal knowledge can travel effectively in an AI-driven world is essential. Most websites are built for human users, not AI, which means systems often process large amounts of irrelevant data, increasing cost and energy use. For TCLP, this is about maintaining access to high-quality, climate-aligned legal content at a time when the way information is accessed is fundamentally changing. This plugin addresses that by delivering a clean, machine-readable version of content, enabling more efficient retrieval for tasks such as research, drafting, and analysis.”

Environmental impact

The launch also draws attention to the growing debate over the environmental footprint of AI systems and digital infrastructure. While much of that discussion has focused on data centres and model training, software design choices that reduce unnecessary processing are also becoming part of the conversation.

TCLP said the project received support from the Patrick J. McGovern Foundation, which backs work on AI and digital infrastructure. The nonprofit described the plugin as a public good and said it wanted developers, charities, and commercial teams to be able to deploy or modify it.

Felix Cohen, director of digital at The Chancery Lane Project, linked the technical change to wider environmental questions. “Improving the efficiency of digital systems is not just a technical concern. It has real environmental implications.

“We see this as an opportunity to connect legal innovation, digital infrastructure, and climate outcomes practically.”

Supporters of the project argue that small efficiency gains can become meaningful when applied across widely used publishing systems such as WordPress. The software underpins a large share of the web, making it a useful starting point for experiments in simpler machine-readable publishing.

Nick Cain, vice president of strategy and innovation at the Patrick J. McGovern Foundation, pointed to the cumulative effect of AI traffic online. “Every query processed and every token consumed carries computational and energy demands that compound across the modern web. At WordPress’s scale, a 90% reduction in token load translates into a substantive gain for the climate. This work reflects our belief that responsible AI infrastructure, built openly for any organisation to deploy, should serve both the public good and the planet.”

For TCLP, the plugin also reflects a practical response to changes in how users find specialist information. “Rather than a shift into technology, this is a continuation of TCLP’s role in enabling climate action through law,” Metz said.

“It’s an extension into the systems that shape how knowledge is accessed and applied.”
