Highlightgpt – Highlight

HighlightGPT lets you highlight text in ChatGPT to instantly ask questions, explain concepts, translate text, and save notes — without copy and paste.

This Chrome extension adds a smart highlight toolbar inside ChatGPT, turning any selected text into instant AI actions:
- Ask questions about the highlighted snippet
- Explain concepts in plain language (or in-depth)
- Translate while preserving tone and nuance
- Save key points for later reference using ChatGPT’s built-in features.

- Context stays on screen: answers appear in a slim side panel, so you keep reading without losing your place.
- 0 extra tokens: works directly inside ChatGPT’s native web experience — no separate model or token billing.
- Privacy-first: answers are generated by ChatGPT only.

Best for:
- Students and researchers using ChatGPT for explanations and summaries
