fastapi-react-chat is an application built to let you chat with an AI using a clean and modern design. The app uses a system that saves your chat history safely, so you can pick up where you left off. It runs smoothly on Windows and connects to OpenAI’s API to create smart replies. You don’t need to know programming to use it.
This app shows how well FastAPI (a Python framework) and React (a JavaScript tool) can work together. It uses a method called N-Layer Architecture to keep the app’s code neat and easy to manage. The saved chat histories live in a PostgreSQL database, which keeps your conversations safe and available even after you close the app.

fastapi-react-chat connects to a smart AI in the cloud. When you type a message, it sends this to the AI, which thinks and sends back a response. Your messages and replies save in the app so you can review them anytime.
The app’s interface comes from React, a user interface tool that helps keep the chat smooth and easy to read. The backend uses FastAPI, a Python tool known for being fast and reliable. The stored chat data uses PostgreSQL, a trusted database tool.
You can switch to dark mode to make the screen easier on your eyes, especially in low light. Find the toggle button, usually at the top right. Click it to change between light and dark themes.
Every conversation you have is saved locally or in the database so you can look back later. This means you don’t have to remember previous chats or lose the information if you close the app.
To view past chats:
- Open the history tab in the app.
- Scroll through previous conversations with the AI.
You can delete chats if you want by selecting the chat and choosing the delete option.
If the app does not start:
- Check if your Windows is up to date.
- Ensure you downloaded the correct installer for your system.
- Restart your computer and try again.
- Confirm you have an active internet connection.
If the AI does not respond or seems slow:
- This could be a problem with internet connection.
- Try closing the app and reopening it.
- Wait a moment and try again.
- Right-click the installer and choose "Run as administrator."
- Disable any antivirus temporarily during setup if it blocks the installation.
- Make sure no other installations are running at the same time.
If you have trouble installing:
Your chat data is stored securely in a local database or PostgreSQL. Connection to the AI uses secure internet protocols. No personal data is sent outside the app except your chat messages needed for AI responses.
You can use the app offline but AI replies require an internet connection.
If you need more help, you can ask for guidance on the GitHub page or check its discussions. The app is designed to be easy, so most users find it runs smoothly after installing.
