Article Summary Length Adjuster

WHAT IT DOES

Article Summary Length Adjuster analyzes any article and generates a summary at the length you choose, from a brief 10% extract to the full 100% text. The extension uses sentence extraction based on keyword frequency and relevance scoring to identify the most important sentences in the article. A slider lets you adjust the summary length in real-time, and you can view the summary in an overlay, a sidebar, or replace the article entirely. Key sentences can be highlighted for easy scanning, and the summary can be copied to the clipboard or exported as plain text. The summary updates dynamically when the page content changes, making it ideal for long-form articles, documentation, and research papers.

WHERE IT RUNS

The extension works on every website with article-style content, including news sites, blogs, academic papers, documentation pages, and any other page with substantial text content. It runs locally in your browser, analyzing the page's content and generating summaries without sending any data to external servers. The extension supports all major browsers and adapts to both desktop and mobile viewports seamlessly.

HOW TO USE

After installation, a "📄 Summarize" badge appears on articles with sufficient content. Click the badge to generate a summary. The summary appears in your chosen display mode: Overlay (a popup in the center of the screen), Sidebar (a panel on the right side), or Replace (the article is replaced by the summary). Use the slider to adjust the summary length from 10% to 100%—the summary updates instantly. Click "Copy" to copy the summary text to your clipboard. In overlay mode, click "Replace Article" to replace the original content with the summary. To restore the original article, click the "Restore Original" button in the panel or use the "Restore Original" button in the main settings panel. Toggle "Highlight key sentences" to visually distinguish the most important sentences in the summary.

THE ACTUAL MECHANISM — SENTENCE SCORING WITH KEYWORD FREQUENCY AND POSITIONAL WEIGHTING

The extension uses a sentence extraction algorithm that scores each sentence in the article based on multiple factors. First, it tokenizes the article into sentences using punctuation boundaries (. ! ?). Then it builds a keyword frequency map, counting how often each non-stop word appears across the article. Each sentence is scored by summing the frequency weights of its keywords, with additional weight given to non-stop words (0.1 points per non-stop word) and a length bonus (0.05 points per non-stop word). Sentences with higher scores are considered more relevant. The extension also accounts for stop words (a pre-defined list of common words like "the", "and", "of") to focus on content-bearing terms. Once scored, sentences are sorted by score in descending order, and the top N sentences are selected based on the target length percentage. Selected sentences are then re-sorted to their original order to maintain narrative flow. The algorithm includes a position bonus that slightly favors earlier sentences, as introductions often contain key information. The summary is rendered with optional highlighting on key sentences to help users quickly scan the most important content. The entire process runs client-side, processing the article's text content without external API calls.

THE PANEL

The settings panel is a lightweight, draggable overlay that appears in the center of your screen. You can reposition it by clicking and dragging the title bar; release it near the screen edge and it will snap into place automatically. To collapse the panel into a compact title bar, click the minimize button, expanding it again with the same control. The panel is fully responsive, adapting to different screen resolutions with a minimum width of 300px and a maximum of 480px. Press the Escape key at any time to dismiss the panel without applying changes. All controls—the enable/disable toggle, generate summary button, close summary button, restore original button, default length slider, display mode selector, title inclusion toggle, key sentence highlight toggle, and per-site enable/disable controls—are accessible within a clean, high-contrast interface that respects your system's color scheme.

PLEASE NOTE

This extension requires the free BotGentz companion extension to be installed and active, which provides the underlying DOM access, clipboard, and storage engine. The summary generation uses sentence extraction rather than abstractive summarization, meaning it selects and rearranges existing sentences from the article rather than generating new text. This approach preserves the original wording and meaning but may not capture all nuance. The algorithm works best on articles with clear sentence structure and sufficient keyword density—very short articles (under 100 words) may not generate meaningful summaries. No personal data, browsing history, or article content is ever collected, stored, or transmitted. All settings are saved using the browser's storage API and remain solely on your device. The extension does not inject ads, trackers, or analytics of any kind.
