Text Snippet Manager

WHAT IT DOES

Text Snippet Manager is a browser extension that lets you save, organize, and insert pre-defined text snippets into any input field, textarea, or content-editable element on any webpage. It allows you to create snippets with labels and content, organize them into custom categories, and insert them with a single click. The tool includes search functionality to quickly find snippets, category filtering, and both insert and copy-to-clipboard options. Snippets are stored persistently in your browser and sync across all websites you visit. The tool is ideal for customer support representatives, content creators, developers, writers, and anyone who frequently types repetitive text, responses, code blocks, or templates.

WHERE IT RUNS

Text Snippet Manager works on any webpage that contains input fields, textareas, or content-editable elements. It runs locally in your browser as a lightweight userscript, managing snippets entirely on the client side. It works on form pages, chat interfaces, email clients, content management systems, code editors, social media platforms, and any other page where text input is used. The tool handles static pages, dynamically loaded content via AJAX, and single-page applications where content updates without page reloads. All snippet data is stored locally using GM_setValue—no text is ever sent to any server.

HOW TO USE

After installation, open the floating panel by clicking the extension icon. The panel shows a list of your saved snippets organized by category. To add a new snippet, enter a label, the snippet content, and choose a category, then click Add Snippet. Use the search bar to filter snippets by label, content, or category. Click the category buttons to filter snippets by category, or click "All" to view everything. To insert a snippet, first focus the input field where you want the text to appear, then click the 📝 (insert) button next to the snippet—the text will be inserted at the cursor position. Click the 📋 (copy) button to copy the snippet to your clipboard without inserting. Click the ✕ (delete) button to remove a snippet you no longer need. All snippets and categories are saved automatically and persist across browser sessions.

REAL MECHANISM — WHY THIS WORKS

Most text snippet tools rely on global keyboard shortcuts or system-level clipboard managers that cannot intelligently insert text into specific web input fields. Text Snippet Manager uses a DOM-aware insertion engine that works directly with the active input element. The engine first detects the currently focused input field, textarea, or content-editable element by listening to focus events. When a user clicks the insert button, the engine determines the cursor position using the element's selectionStart and selectionEnd properties (for input and textarea elements) or using the Selection API (for content-editable elements). The engine then constructs the new text by concatenating the text before the cursor, the snippet content, and the text after the cursor, ensuring that existing content is preserved. For React and Vue applications, the engine dispatches both "input" and "change" events after modifying the value, ensuring that reactive frameworks detect the change and update their state accordingly. The snippet data is stored as a JSON array using GM_setValue, with each snippet containing an id, label, content, and category. This approach ensures accurate, framework-compatible text insertion without requiring any external services or clipboard interaction when inserting directly into fields.

THE PANEL

The floating panel is fully draggable and remembers its position per site, snapping to the edges of the viewport when dragged near them. You can collapse the panel to a small icon to minimize screen distraction and expand it back with a single click. The panel is resizable from the bottom-right corner, giving you more space to view snippets and controls. Press the Escape key to close the panel instantly. The panel remains open across page navigation within the same domain, maintaining your current view state. All preferences—panel position—are saved per domain for a seamless experience.

PLEASE NOTE

Text Snippet Manager requires the free BotGentz extension to be installed and enabled, as it relies on the cross-extension messaging API provided by BotGentz for DOM access permissions. Because websites frequently update their structure, snippet insertion may require periodic script updates to maintain compatibility with specific input fields or rich-text editors. If the tool does not insert snippets as expected, please check for updates or report the issue. All snippet data is stored locally in your browser using GM_setValue. No snippet content, labels, categories, or usage data are ever sent to any server. The extension does not read, store, or transmit any personal information. It only reads the DOM to detect input fields and write text at the cursor position at your explicit request.
