HighlightGPT is a lightweight browser extension designed to enhance the ChatGPT experience by enabling users to interact with highlighted text directly within the ChatGPT interface. It allows for asking questions, getting explanations, translating content, and saving important information to memory without leaving the ChatGPT environment.

The extension provides a highlight toolbar inside ChatGPT that appears when text is selected, enabling one-tap actions to ask or explain highlighted content. It features a context-aware side panel that displays answers alongside the main chat, allowing uninterrupted reading. Users can translate ChatGPT replies instantly while preserving tone and nuance, and save key responses to ChatGPT's memory for future reference.

HighlightGPT operates entirely on ChatGPT's native web experience, requiring zero extra tokens and maintaining response quality. It integrates seamlessly by using the existing ChatGPT interface without additional API calls or token consumption.

The benefits include streamlined workflows for reading and thinking within ChatGPT, eliminating the need to retype prompts or switch contexts. Use cases include researching documents, learning from explanations, translating content accurately, and building personalized knowledge bases through memory features.

Target users are individuals who regularly use ChatGPT for productivity, research, or learning tasks and seek to optimize their interaction workflow. The extension is specifically designed as a Chrome browser add-on that enhances the native ChatGPT web interface.
