Definity Plans AI Assistant for Vyne Broker Platform

By Grace Kim

Definity Financial Corporation and Guidewire said on November 12, 2026 that Definity will introduce Guidewire’s ProNavigator across three insurance lines in its Vyne digital broker platform, with no availability date announced.

What will brokers get?

The planned deployment covers three areas:

• Personal auto
• Personal property
• Individually Rated Commercial Auto work

Definity will brand the assistant Definity Assist, the companies said. Brokers will be able to ask questions in everyday language and see answers inside their current Guidewire workflow, according to the announcement.

Definity expects Definity Assist to make broker work more efficient, resolve inquiries faster, reduce the learning curve for new staff and improve customer interactions. The project uses Definity’s existing policy-servicing workflows and draws on more than a decade of experience applying AI across insurance.

The in-workflow design makes operating speed central to the business case, according to the announcement. Definity gave no response-time target, productivity estimate or launch schedule, so those gains remain expectations rather than measured results. In practical terms, Definity expects faster inquiry resolution and a shorter learning curve for new staff.

How will broker questions shape support?

The deployment also gives Definity a way to learn from broker demand, according to the companies. Questions should reveal where help content, training and policy documentation need improvement. Definity can use those findings to guide process changes and future AI-driven broker experiences.

The announcement gives the project a second function beyond question answering. Individual brokers get help in the moment, while patterns across their questions expose recurring weaknesses in supporting materials. Acting on those patterns would let Definity address the source of repeated inquiries as well as the inquiries themselves.

The announcement describes a feedback loop for support operations. Broker demand can identify gaps in help content, training or policy documentation, and Definity can use the findings to strengthen the underlying support. The practical result would be better answers now and stronger training and documentation over time.

What technology will power ProNavigator?

Guidewire’s ProNavigator documentation places the assistant in a sidebar within core applications. It can supply answers, suggestions and actions based on a user’s current work, Guidewire said.

The product runs on Anthropic’s Claude models. Guidewire uses the Converse API to interpret tables and graphics in documents such as underwriting manuals. It also uses Claude’s Citations feature to attach paragraph-level references to answers, allowing users to trace a response to the underlying source material.

For retrieval-augmented generation, which grounds answers in retrieved content, each customer receives its own vector database. Guidewire said the dedicated store keeps client data segregated. Its design separates the source material used to ground an answer from the customer data of other clients.

Guidewire built the technology to answer from authorized documents while showing its work.

How will access and review work?

ProNavigator maps access rules to business categories such as region and insurance line. It uses single sign-on to apply role-based permissions consistently to source documents, searches and generated responses, Guidewire said.

The assistant records queries, responses and their citations. Guidewire said those records support compliance teams, audits and claims disputes. Human oversight applies to every AI-generated insight, according to the company.

Guidewire also said the architecture protects personally identifiable information and keeps proprietary customer data from being used to train public models. The practical takeaway is simple: answers should remain traceable, permissions consistent and sensitive data separated.

When will Definity launch Definity Assist?

Guidewire’s announcement describes ProNavigator generally and does not specify Definity’s exact configuration. The companies have not given an availability date for Definity Assist, and the announcement does not say which product controls will apply to the planned service.

That leaves the commercial and operational claims ahead of proof. The announcement frames the central test as whether faster answers can coexist with source citations, access controls and human review, while Definity turns broker-query patterns into better supporting material.

Definity’s next proof point is whether it can combine faster answers with traceable sourcing, controlled access and human review in Vyne. If broker questions also expose gaps in training and policy documentation, the November 12 plan could improve both the service brokers use and the support system behind it.
