Allianz UK rolls out generative AI tool for underwriters

Allianz UK  has rolled out BRIAN, a generative AI tool built to speed up how commercial underwriters access guidance. Trained on underwriting manuals, BRIAN gives direct answers with links to source docs—helping underwriters skip the search and get straight to decisions.

After piloting with 190 users and nearly 3,000 test questions, BRIAN went live in January and has since handled over 13,000 queries, saving an estimated 135 workdays. The tool is active in Property and Liability and is set to expand across all commercial lines by year-end.

BRIAN, named after a former Allianz colleague, is said to be especially useful for junior underwriters, helping them learn faster while improving consistency and efficiency across the board.

“What sets BRIAN apart is its dual functionality. It provides a concise answer and includes a direct link to the specific section of the guidance document used to generate the response, allowing underwriters to delve deeper if needed. Typically, our underwriters spend around two hours a week looking for information on internal documents. With BRIAN it takes just seconds.

This is not about replacing decision-making, but equipping people with better tools to access information they need at the moment they need it. With the extra time saved, underwriters can focus on deeper risk analysis, enhancing customer relationships, refining pricing strategies, and staying updated on emerging market trends and regulatory changes.” – Benjamin Blackie, Transformation Business Owner at Allianz UK.
