How We Built an AI Financial Agent Using Retool, GPT-4o & Alpha Vantage

Building a Smarter Fintech Experience with AI

At iView Labs, a leading Wix Studio development company, we’re creating intelligent fintech tools that do more than just fetch data - they act like human advisors. Our latest development? A smart AI Financial Agent built on Retool, integrated with GPT-4o, Claude, and real-time APIs like Alpha Vantage.

This application functions like a virtual financial expert, providing users with clear, contextual answers to complex questions based on real-time data.

What the AI Agent Can Do

We're building the agent to work like a fintech assistant that can:

•  Fetch real-time market and portfolio data 

• Answer user queries in plain language 

• Suggest action steps based on financial logic 

• Flag high-risk patterns and upcoming issues

How We Built It on Retool

As a Wix Studio development company, we often merge design with function. Here’s how we combined our low-code expertise with AI to build this solution:

1. Multi-API Integration

We integrated the Alpha Vantage API to fetch detailed financial data — from stock quotes to economic indicators.

2. AI Models: GPT-4o + Claude

We’re using a combination of OpenAI GPT-4o and Anthropic Claude 3 for intelligent query handling and contextual response generation.

3. Custom Rulebook via Instruction Sets

The AI agent follows a set of structured, prompt-based rules, ensuring answers are consistent, compliant, and within business logic.

4. Dynamic UI with Retool

Using Retool’s UI builder, we created user-friendly dashboards where users and admins can interact with the agent, monitor usage, and review logs.

Upcoming Feature: Risk Score Engine

The next milestone is a Risk Scoring System, which will:

• Analyse financial health using transactional data

• Generate dynamic risk scores

• Suggest critical actions when thresholds are crossed (e.g., "consider reallocating assets", "reduce exposure to X", etc.)

Why Retool for AI in Fintech?

Retool gave us the speed of a low-code platform and the flexibility of custom code. Perfect for startups and enterprises looking to:

• Build AI-powered internal tools fast

• Run custom workflows on live data

• Embed LLMs like GPT or Claude directly in dashboards

• Scale securely with modern cloud architecture

Final Thoughts

With this project, we’ve shown how AI agents in fintech can move from theory to reality,  fast. Retool, combined with GPT-4o and financial APIs, allowed us to build a robust MVP in record time.

Whether you’re a fintech startup or a financial institution, intelligent agents like these will redefine how your users interact with money.
