Hackathon Recap: Building ACE at the 2026 Drupal AI Event

Staff Reporter

A recent recap from Ronald te Brake reflects on the Drupal AI Hackathon – Play to Impact: 2026 edition held at the European Commission, where his team developed a prototype called ACE (Augmented Content Editor). The event brought together developers and business professionals to explore practical applications of artificial intelligence within Drupal, grounded in real editorial workflows.

The team centred its work on a recurring challenge in content operations: editorial feedback improves individual drafts but is rarely preserved as structured knowledge. Review comments are often repeated across projects, with little mechanism to carry those lessons forward. ACE was designed to address that gap by capturing feedback and applying configurable editorial guidelines through the AI Context module.

Workflow orchestration was implemented using the FlowDrop module, while scoring and evaluation were powered by models from Mistral AI, a sponsor of the event. The prototype provided editors with structured scoring and actionable recommendations tied directly to configurable organisational guidelines.

Rather than replacing human reviewers, the system was conceived as an augmentation layer. Feedback is stored per revision, enabling trend analysis over time. The team also explored modeling content, revisions, and guidelines as interconnected data structures, similar to a knowledge graph approach, allowing historically grounded context to inform future drafts.

According to the blog, direct access to European Commission content editors during the discovery phase significantly shaped the solution. Early conversations helped the team focus on workflow realities rather than hypothetical use cases, reinforcing the value of user-centred collaboration in AI experimentation.

The hackathon was organised by the Drupal Community of Practice with facilitation support from NTT DATA and sponsorship from amazee.io, Mistral AI, DevPanel, and other partners. The recap concludes on a reflective note, highlighting the intensity, collaboration, and practical focus that defined the event.
