HighlightGPT is a lightweight browser extension that adds highlight-based interaction capabilities directly to the ChatGPT web interface. It is designed for users who regularly work with ChatGPT and want to streamline their workflow by interacting with selected text without leaving the page. The tool serves as a productivity enhancer, allowing users to ask questions, get explanations, translate content, and memorize key information from any highlighted text within ChatGPT.

Many ChatGPT users face workflow interruptions when they need to ask follow-up questions about specific parts of a response or want to understand, translate, or remember particular segments. This requires copying text, pasting it into new prompts, or navigating away from the main conversation, which breaks concentration and adds unnecessary steps. HighlightGPT solves this by embedding interaction tools directly into the browsing experience, eliminating these friction points and maintaining a seamless workflow.

One key feature is the highlight-to-ask functionality, which allows users to select any text within ChatGPT and send it directly to the AI for processing. This enables immediate questions, explanations, translations, or memorization actions without retyping or creating extra prompts. The system integrates a toolbar that appears when text is selected, providing one-tap access to these core functions, thereby saving time and reducing manual input.

Another significant capability is the context-aware side panel that displays highlight-based answers. This slim panel appears beside the main ChatGPT conversation, allowing users to keep reading the primary response while viewing additional explanations or translations related to their selected text. This dual-view approach prevents interruptions and enables parallel processing of information, enhancing comprehension and productivity during extended chat sessions.

The extension includes memory integration features that let users save important answers directly to ChatGPT's memory system. By pushing key responses to memory, future AI answers stay aligned with previously established context and important information. This creates a more personalized and consistent interaction over time, as ChatGPT can reference these saved insights when generating new responses, building a cumulative knowledge base within conversations.

HighlightGPT operates entirely within ChatGPT's native web experience without consuming additional tokens. The extension leverages the existing ChatGPT interface and infrastructure, meaning all interactions use the same token allocation as standard prompts. This zero-extra-token approach ensures there are no hidden costs or compromises on response quality while providing enhanced functionality, making it economically efficient for frequent users.
