Overview

Turning complex financial data into timely, trustworthy conversations.

Adot is SKT’s AI assistant, used by 3M+ users each month. I designed Stock Agent, one of five key features introduced as part of Adot’s major relaunch.

Stock Agent helps everyday investors find and understand complex financial information without searching across multiple services. I shaped its conversational flows, in-app screens, and dialogue guidelines, from initial concept to post-launch improvements.

Problem

AI could hold a conversation. But could users trust it with their money?

At the time, AI models were good at natural, everyday conversations. More complex topics were different. Hallucinations made users hesitant to rely on AI for information that could affect important decisions.

Financial information made this trust gap especially clear. We saw an opportunity to ground the AI in verified data from our securities partner and make it useful for more serious, high-stakes needs.

Research

We focused on everyday investors who wanted to make informed decisions.

Adot’s user demographics closely matched those of individual investors. 68.6% of Adot users had also used a stock investing service within the past 30 days.

Our research revealed two recurring challenges.

01

Finding information at the right time

Users moved between trading apps, news, YouTube, and online communities to stay informed. Important updates were easy to miss.

02

Understanding what the information meant

Prices and disclosures were readily available, but context was not. Users often searched elsewhere to understand market changes and complex financial terms.

Design Approach

Make financial information timely, clear, and trustworthy.

Timely

Bring important updates to users before they have to search.

Clear

Turn complex financial information into concise, conversational explanations.

Trustworthy

Ground every response in verified data from securities partners.

Key Features

01

Stay informed without searching

Stock Agent proactively delivered updates based on each user’s interests. Morning briefings, disclosure summaries, and IPO reminders helped users catch important information at the right time.

02

Ask naturally and get grounded answers

Users could search for stocks, financial metrics, news, and market themes through conversation. Responses were grounded in verified data and presented in a concise, easy-to-understand format. Contextual prompts helped users ask follow-up questions and explore topics in more depth.

03

Go beyond the conversation

Not every piece of financial information works well in a chat. I designed dedicated screens for stock details and watchlists, making charts, news, disclosures, and financial statements easier to scan and compare.

Outcomes & Iteration

33,963 users in the first month

The Stock Agent launched in September 2024 as one of Adot’s flagship experiences. Within its first month, 33,963 users tried the feature.

After launch, we found that returning users were asking more complex and detailed questions. We expanded the range of supported queries and made the Agent more flexible in handling follow-up conversations.

We also introduced timely news alerts for stocks on each user’s watchlist. Users could open a concise AI summary directly from the notification and quickly understand what had changed.

What I learned

Trust in AI comes from more than accurate answers. It also depends on using reliable sources, showing information in the right format, and delivering it at the right moment.
