Creating dynamic profile pages for 1300 tax experts with the help of genAI
How I prioritized safety, accuracy and voice to summarize 20,000 client reviews.
Overview

For Tax Year 2024, the design team re-imagined TurboTax Live to, "Lead with the Experts," an ambitious shift that allows customers to create a personal connection with their tax expert.
​
TurboTax clients rely on user reviews to make financial decisions.
​​
With the help of Generative AI, I provided concise, informative summaries of client feedback on each expert's profile page.​

Goal
Accurate, on-brand review summaries
Working with a tax expert can be a big financial commitment. TurboTax clients asked for a window into the experience before they commit.
​​
Inspired by review summaries on Yelp and Google Maps, we turned to our internal genAI models to create unique and relevant review summaries for each expert profile.
Process
Iterate
I partnered with the engineer team to iterate on over 20 versions of our original prompt, with a focus on accuracy and voice.

​To guide the LLM to the target voice, I included word count, reading level and an output example.
​
To curb incidents of hallucinations, I instructed the LLM to avoid exaggerated statements.
Evaluate

I manually reviewed 50-80 responses to each prompt for accuracy, hallucinations and voice.
​
Once I developed a prompt with high accuracy and low hallucinations, I turned to the Security Team.
Challenge
Safeguard against prompt injection
With the help of the Security Team, we tested our prompt against a series of malicious scenarios.

As you can see, the test results weren't great. Nearly 100% of the prompt injection attacks were successful.
​
We needed to solve for prompt injection.
Solution
Detailed instructions and HTML tags
Armed with a Secure Prompt Cookbook, I revised the latest prompt with sections, HTML formatting, and more robust instructions.
​
This time, I was sure to include directions to ignore instructions found in the user input.
<INSTRUCTIONS>
You’re a TurboTax writer providing SUMMARIES of REVIEWS of our Full Service tax experts.
​

</INSTRUCTIONS>
Consistent terms
​Conversationally, Intuit product partners have a habit of referring to "Customers," "Users," and "Clients," interchangeably.
LLMs need consistency just like us humans. I removed any reference to the users to focus the behavior on collecting info from the REVIEWS and {{user_input}}.
Results
Within 3 revisions, I was able to drop prompt injection incidents from 80 to 1.

We received sign off from the Legal and Security Teams, just in time for tax season.
​
Over 20,000 user reviews were summarized for 1,300 expert profiles, bolstering our new initiative and securing a 50% increase to early-season conversion rates.
In retrospect

Human intervention and on-going evaluation
GenAI technology is spectacular, but still needs human intervention to create, evaluate and iterate.
​
Throughout the process, we ran into limitations with the current state of the technology, that posed various risks to the user experience.
​
Luckily, we saved the output to a data lake, before populating the expert profiles. Because of this, we can review the output for safe content before it's shown to the user.
