Chat GPT-4 is integrated into the mobile application.

AI assistant in the mobile application — integration of GPT-4o

Task:
Add a smart financial assistant that analyzes the user's expenses and provides personalized advice — not template-based, but based on real data.

Solution:
Integrated GPT-4o-mini through OpenAI API into the React Native mobile application.

How it works:
— The application transmits the user's spending context
— GPT analyzes patterns and formulates a personal recommendation
— The response appears in the UI as a message from the character Nazarik
— In the Free version: 2 recommendations per week
— In the PRO version: full AI chat without limitations

Technical implementation:
— Supabase Edge Function as a proxy to OpenAI API
— Spending context is transmitted from the database
— GPT-4o-mini for speed and low cost
— GPT-4o Vision for scanning receipts (in development)

Stack:
OpenAI GPT-4o-mini · Supabase Edge Functions
React Native · TypeScript

Result:
AI works in a real application.
Personalized advice based on data — not generic responses.
