About the project

What is Aulevo Chat GPT Booster Chrome Extension?

This project involved developing a Chrome extension that significantly improves the performance of long ChatGPT conversations by optimizing how messages are rendered in the browser. Instead of loading entire chat histories at once, the extension intelligently displays only the most recent messages while preserving complete conversation history in the background. The solution was designed as a subscription-based SaaS browser extension with Free and Pro plans, secure authentication, Stripe billing, and cloud-based license management. Built using the Plasmo Framework and Manifest V3, the extension delivers a smoother ChatGPT experience while remaining fully compatible with future browser expansion.

The problem

What was slowing them down.

01
Slow performance in large conversations
Threads containing hundreds of messages caused lag, freezing, and delayed typing.
02
High browser resource usage
Rendering every message increased CPU and memory consumption, reducing responsiveness.
03
No efficient conversation management
Users had to work through increasingly slower chats as conversations grew.
04
Subscription management required
The client needed a secure Free/Pro licensing system with trials and recurring billing.
05
Limited usability
These issues negatively affected productivity and limited the usability of long AI conversations.

The solution

What we built.

A custom Chrome extension

A custom Chrome extension was developed to optimize ChatGPT performance without modifying or deleting conversation history.

Intelligent client-side message rendering engine
Configurable message loading for improved performance
"Load More Messages" functionality for accessing older conversations
Secure user authentication using Supabase
Free and Pro subscription plans with Stripe integration
Three-day free trial with automatic license validation
Quiet Mode and advanced customization for Pro users
Manifest V3 architecture with future Firefox compatibility
The result is a lightweight browser extension that improves ChatGPT responsiveness while maintaining complete privacy.
