Redefining Financial Research Through AI-First Product Design

Accern, the leading NLP company in the U.S. and a Forbes Under 30 honoree, partnered with us in 2022, when AI was just gaining momentum. While building their products, we created design patterns that set the standard and are now used by Anthropic, ChatAI, and other major AI players.

In 2024, Accern returned to collaborate on a new product within their growing digital ecosystem. This time, the focus was a powerful research tool built for financial analysts, VC investors, and ESG specialists, driven by a pre-trained AI model that goes far beyond traditional chatbot functionality.

This case study is a must-read for AI business owners, fintech startups, and enterprise SaaS teams working with large data sets and complex research workflows. It showcases our development of AI functionality that set a new market standard, now adopted by OpenAI and other AI leaders.

Reimagining Financial Research

While designing Rhea’s interface, we avoided overwhelming researchers with unnecessary features. Instead, we focused on delivering only what they need to make informed financial decisions, rather than replicating traditional research methods.


We built a hybrid interface that combines prompt-driven AI functionality with dynamic widgets and graphics. This offers a seamless research-to-report workflow with an intuitive split-screen mode.

Hybrid GUI/Prompt Interface

Given Rhea’s use cases, where users frequently work with graphics, tables, and interactive elements, a purely chat-based interface with text inputs wasn’t enough.


Instead, we designed a widget-based system with a dynamic UI that adapts to the flow of conversation. Rhea can surface references, charts, footnotes, or graphical controls in response to voice or text prompts.

An Adaptive Natural Language Communication System

At the core of Rhea’s capabilities is an adaptive natural language communication system. When AI-generated answers are unclear or users struggle to frame their queries, Rhea steps in with clarifying questions, suggestions, and hints to help users get more accurate results faster. The feature that started as a differentiator is now industry standard, even OpenAI has followed suit.

Report Creator Mode

Rhea goes beyond natural language understanding, covering user comprehension, personalization, file management, and task assistance. This comprehensive suite is supported by robust data processing and synthesis on the backend.

At Lazarev, we committed to actualizing this functionality by transforming the chat field into an advanced search bar and a command line.

Multi-Purpose Input Field

We wanted to make Rhea a multifunctional solution that offers greater value to users. To achieve this, we transformed the standard prompt field into an advanced command line.


This upgrade allows users to search for files, set up notifications, manage automated emails, schedule calls, issue alerts, and handle other key tasks as part of their daily workflows.

Integrated Datasets and File Management

In the settings, people can select pre-configured datasets, called Lenses, or connect their own through Accern's NLP Platform. We added options to upload and manage files and folders, providing essential context for Rhea’s data analysis.

Additionally, we developed custom email notifications to deliver alerts and reports on specific topics, keywords, industries, or any other information researchers find valuable.

To elevate user engagement and foster a deeper comprehension of the available apartments, we crafted the interactive house model within the "Selection of Apartments" section. This immersive experience empowers potential buyers to take a 360-degree tour, flipping between street and yard views with a simple toggle switch. As they hover their cursor or tap (for mobile users),  the house's specific sections illuminate, offering valuable insights into construction timelines and housing readiness. The interactive journey extends to selecting a floor and pinpointing a specific apartment with the help of a visual builder, simplifying the decision-making process and potentially increasing conversion rates.

We introduced an interactive widget at the top of the homepage, allowing users to track upcoming elections and assess their preparedness based on articles read, candidate knowledge, and quiz participation.
