Highlight in ChatGPT, ask GPT in a side panel
HighlightGPT is a Chrome extension that lets you highlight text inside ChatGPT and open a side panel to ask AI, explain, ask, translate, or save memorizes. It’s a small workflow upgrade that makes ChatGPT feel more like a reading & thinking workspace.
HighlightGPT runs entirely on ChatGPT's native web experience with zero extra token usage. All processing occurs within ChatGPT's existing infrastructure, eliminating separate billing or token consumption concerns.
The Pro tier ($8 lifetime) offers unlimited saving to ChatGPT Memory, allowing users to push key responses into ChatGPT's memory system so future answers remain aligned with previously learned information.
HighlightGPT enables one-tap highlighting to send selected text directly to ChatGPT for instant questions, explanations, or translations. Answers appear in a side panel, keeping the main chat visible and eliminating repetitive copy-paste workflows.
HighlightGPT includes instant translation of ChatGPT replies directly from highlighted text, maintaining semantic meaning and conversational tone without requiring separate translation tools or manual intervention.
Students and researchers can highlight any text snippet and request plain-language or in-depth explanations in one tap, with answers displayed in a slim side panel that preserves reading context and flow.
