Summarize On Select by Belagum

Summarize On Select is an AI text summarizer that turns any selection on any page into a concise TL;DR — instantly. Highlight text, press Alt+N (or use the floating button / right-click menu), and a clean popup streams a short summary in real time.

Unlike single-provider tools, you choose the AI: OpenAI GPT, Anthropic Claude, Google Gemini, DeepSeek, Alibaba Qwen, xAI Grok, Mistral, OpenRouter — or any OpenAI-compatible endpoint, including local/self-hosted models. Bring your own API key; it’s stored locally and your text is sent only to the provider you pick — never to us or any third party.

HOW IT WORKS
1. Select any text on any website.
2. Press Alt+N, click the TL;DR button, or use the right-click menu.
3. Read the streaming summary in an in-page popup — then copy it in one click.

KEY FEATURES
• Any AI model — switch freely between GPT, Claude, Gemini, DeepSeek, Qwen, Grok, Mistral, OpenRouter and custom endpoints.
• Real-time streaming output, so you start reading immediately.
• Three ways to trigger: customizable Alt+N keyboard shortcut, a floating TL;DR button, and a right-click context menu.
• Draggable summary window — move it anywhere by its header, and optionally remember its position.
• Customizable floating button — choose its position (left, right, bottom-center, or next to the selection), scale it up or down, toggle it on/off.
• One accent color for the whole UI — match the extension to your taste.
• Adjustable summary length (weak / medium / strong compression).
• Output language: keep the source language automatically, or force English or Russian.
• Light, dark, and auto themes; English and Russian interface.
• Markdown-formatted summaries with support for reasoning models (view the model’s reasoning separately).
• Advanced per-model settings: temperature, max tokens, reasoning effort, and custom request fields.
• Built-in “Copy debug logs” in settings and the toolbar popup for fast troubleshooting.
• Manifest V3, privacy-first, lightweight — works on Chrome and Firefox.

WHO IT’S FOR
Students, researchers, developers, and professionals who need to digest long articles, docs, papers, threads, and reports fast.

PRIVACY
Your API key is stored locally in your browser and is never synced or shared. Selected text is sent only to the AI provider you choose.
