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.
