How does pricing compare?

HighlightGPT: Paid. The extension itself is free to install, but it is not usable without your own OpenAI API key. You pay OpenAI directly for the tokens each explanation consumes, and larger context settings increase that cost. There is no separate subscription sold inside the extension. Intercom: Free Trial, Paid. Intercom offers a 14-day free trial with no credit card required and then subscription tiers, with seats and AI agent resolution volume priced separately. Published pricing exists, but the AI agent component is typically usage-based, so the total depends on conversation volume. Contact sales for enterprise quotes.

HighlightGPT

Highlight any sentence, get an instant, page-aware AI explanation

In-place explanations

Highlight a confusing sentence and receive a short explanation without leaving the page or opening another tab.

Three context levels

Choose how much surrounding page text is sent along with your selection to balance answer quality against API cost.

Automatic request trimming

When a selection plus page context exceeds the request size limit, the extension automatically lowers how much page content it ingests.

Double-click protection

Accidental highlights created by double-clicking are ignored, so the tool only fires when you deliberately select text.

Strengths & Pros

+Explanations use surrounding page text, so answers match the article rather than a generic definition
+No context switching — you stay on the page you are reading
+Adjustable context depth lets you control how much you spend per explanation
+Simple, single-purpose design with automatic handling of oversized requests
