## HighlightGPT

HighlightGPT exists for the moment when a sentence on a webpage does not quite make sense and you do not want to break your reading flow to open a separate chat tab. You highlight the difficult passage and the extension sends it, together with a configurable amount of surrounding page text, to an OpenAI model that returns a plain-language explanation. Because the surrounding paragraph, heading and nearby argument are included, the answer tends to reflect what that sentence means in this specific article rather than a generic dictionary definition.

The extension exposes three levels of context so you can trade accuracy against cost: higher values pull in more of the page and give richer answers, lower values keep requests small and cheap. If a selection is too large for the model's request limit, HighlightGPT automatically reduces how much page content it ingests so the request still goes through. Double-click highlights are deliberately ignored, which prevents accidental triggers while you are simply selecting text to copy.

Setup is minimal but does require an OpenAI API key, and every explanation you generate is billed against that key. The project is a small, single-developer tool published under the name Sacrosaunt, and it upgraded its underlying model to GPT-4o in version 1.1.3. It is best understood as a focused reading aid rather than a full AI assistant suite.

**Pricing & Plans:** 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.

- **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.
- **Bring-your-own-key design:** Runs against your personal OpenAI API key, keeping you in control of model choice, quota and spend.

**Strengths:** 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

**Limitations:** Requires your own OpenAI API key, which adds setup friction for non-technical users; High context settings can consume your OpenAI quota quickly; Small user base and a narrow feature set — it explains text and little else

## Text Selected

Text Selected is a small, single-purpose Chrome extension. Its job is narrow and clear: you highlight text on a web page, pick the extension's option from the right-click context menu, and it returns a relevant answer without you having to open a new tab or search engine.

Under the hood the extension sends the selected text to a remote service, which looks through a JSON file hosted on Google Cloud Storage for the corresponding entry. The answer is shown in a simple browser alert, so the interaction stays inside the page you were already on. This makes it useful for quick reference lookups where the source data is already curated in the backing file rather than generated on demand.

Because answers come from a fixed dataset, what you get back depends on what the JSON file contains; it is not a general-purpose AI chatbot. The extension is free, published by an individual developer, version 2.0, and uses a Spanish (Latin America) interface, with a declared data policy covering user activity and website content.

**Pricing & Plans:** Free. The extension has no paid tier or subscription; you install it from the Chrome Web Store and use it at no cost.

- **Select text anywhere:** Works with any page: highlight a word or phrase and use the context menu to submit it.
- **Remote JSON lookup:** The selection is sent to a remote service that searches a JSON file for a corresponding answer.
- **Instant alert response:** Results appear immediately in a browser alert so you can read them without leaving the page.
- **Minimal footprint:** Small, focused add-on that does one job: fetch relevant information for the text you selected.

**Strengths:** Free with no account or subscription; Answers appear in a simple alert without leaving the current page; Works from the standard right-click context menu; Very small download (around 28 KB)

**Limitations:** Answers are limited to whatever is stored in the remote JSON file; Spanish (Latin America) interface only; Relies on a remote service, so it needs an internet connection; No ratings and a small user base
