Summarize On Select

By: Belagum
Highlight text, press Alt+N, get an instant AI summary. Use GPT, Claude, Gemini, DeepSeek, Grok, Mistral, OpenRouter or any OpenAI-compatible model. Real-time streaming, a draggable TL;DR popup, your API key stays local. Chrome & Firefox.

Features & Capabilities

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.

NEW IN 2.1 • Drag the summary window anywhere (with optional position memory). • Floating button: configurable position, size, on/off, and a global accent color. • Copy debug logs from settings and the toolbar popup.

Is Summarize On Select Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Summarize On Select requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Summarize On Select may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
