Definity Financial Corporation will introduce Guidewire’s ProNavigator assistant in its Vyne digital broker platform under a plan announced with Guidewire on November 12, 2026, covering personal auto, personal property and Individually Rated Commercial Auto work.
The assistant will be branded Definity Assist. Brokers will be able to use everyday language to request information and see the answer within their current Guidewire workflow. The companies presented the integration as a planned deployment and did not provide an availability date.
Definity expects the assistant to make broker work more efficient, resolve inquiries faster and reduce the learning curve for new staff, while improving customer interactions. The project uses Definity’s existing policy-servicing workflows and draws on more than a decade of experience applying AI across insurance.
Broker Queries Will Guide Supporting Material
The deployment also gives Definity a way to learn from broker demand. Questions are intended to show where help content, training and policy documentation need improvement, and the resulting insights will inform process changes and future AI-driven broker experiences.
That gives the deployment a second function beyond question answering. Individual brokers get help in the moment, while patterns across their questions can expose recurring weaknesses in supporting material. Acting on those patterns would allow Definity to address the source of repeated inquiries as well as the inquiries themselves.
ProNavigator’s Models and Access Controls
Guidewire’s ProNavigator documentation places the assistant in a sidebar within core applications, where it can supply answers, suggestions and actions based on the user’s current work. The product runs on Anthropic’s Claude models; Guidewire uses the Converse API to interpret tables and graphics in documents such as underwriting manuals, and Claude’s Citations feature to attach paragraph-level references to answers.
For retrieval-augmented generation, which grounds answers in retrieved content, each customer receives its own vector database. Guidewire says the dedicated store keeps client data segregated. ProNavigator also maps access rules to business categories such as region or insurance line and uses single sign-on to apply role-based permissions consistently to source documents, searches and generated responses.
To support review, ProNavigator records queries, responses and their citations for compliance teams, audits and claims disputes. Guidewire says human oversight applies to every AI-generated insight, while the architecture protects personally identifiable information and keeps proprietary customer data from being used to train public models.
These details describe ProNavigator generally; the announcement does not specify Definity’s exact configuration. The planned service’s central test is whether faster answers can coexist with source citations, access controls and human review, while Definity turns broker query data into better supporting material.
