## Overview

One-Click Lesson is a small Chrome extension built for people who read on the web and keep hitting unfamiliar terms. Instead of opening a new tab, copying the phrase and pasting it into a chatbot, you highlight the word or idea, right-click, and a concise AI explanation is rendered on the page. The extension is deliberately minimal — a 27 KB package with a single focused job — so it stays out of the way while you read.

The workflow is built around staying in flow. Because the explanation appears where you are already reading, you do not lose your place or context, which is the main friction that interrupts research, study sessions and long documentation reads. Version 1.1 added a customizable learning prompt, so you can shape the tone and depth of the answers the assistant gives you, and avoid re-typing the same instruction to a general-purpose LLM over and over.

The extension is published on the Chrome Web Store for free and is listed under tools for learning and productivity. It is aimed at students, researchers and anyone who reads a lot of technical or second-language material and prefers a low-friction explanation over a full chat session.

## Pricing & Plans

Free to install and use from the Chrome Web Store. No paid tiers or in-app purchases are published.

## Key Features & Capabilities

- **Highlight-and-explain:** Select any word or idea on a webpage, right-click, and receive an AI-generated explanation in seconds.
- **Answers stay on the page:** Explanations render over the content you are already reading, so you never lose your place to a new tab.
- **Custom learning prompt:** Since v1.1 you can edit the extension's prompt to control how detailed, simple or technical the explanations are.
- **Featherweight footprint:** The whole extension is roughly 27 KB, so it loads fast and adds negligible overhead to browsing.
- **Privacy-conscious listing:** The developer declares data is not sold to third parties nor used for unrelated advertising or creditworthiness purposes.

## Primary Use Cases

- **Study without breaking concentration (Student):** Highlight unfamiliar terminology in lecture notes, articles or PDFs and get a plain-language explanation right where you are reading.
- **Speed up literature review (Researcher):** Clear up jargon and acronyms in papers and documentation instantly instead of detouring into a separate chat window for every term.
- **Explain phrases in context (Language learner):** Highlight an expression in a foreign-language article to understand what it means in the surrounding passage, not in isolation.
- **Decode docs while you build (Developer):** Turn densely written API docs and release notes into short explainers without leaving the page you are coding against.
