Intent

I need it when

Enhance ChatGPT productivity without incurring additional token costs or API charges

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.

Save and reference important ChatGPT responses for future consistency and knowledge retention

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.

Quickly extract and ask questions about specific text passages while reading in ChatGPT without manual copy-paste

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.

Translate ChatGPT responses while preserving tone and nuance across multiple languages

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.

Streamline research and learning workflows by explaining concepts directly from highlighted text in ChatGPT

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.
