TL;DR (Too Long; Didn't Read) - Chrome Extension

English | Russian

This extension allows you to quickly obtain a brief summary of any web page or selected text. It helps you quickly retrieve the main ideas and points from a long text by querying the OpenAI API (or an alternative service).

Features

• Toolbar Button: Clicking extracts the entire page text and sends it for summarization.
• Context Menu: Allows summarizing selected text via right-click and choosing the "Summarize via TL;DR" command.
• API Integration: Sending text for summarization using a customizable system prompt (default: "Summarize this text in 3 key points. Format each point as a proper Markdown."). API requests are configurable through settings.
• Extension Settings: Settings page allows you to set:
  • Base URL for API
  • API Key
  • System prompt
  • Model (text field, default: "o3-mini")
  • Advanced Settings:
    • Temperature (default: 0.8, range: 0-2.0) - Controls randomness in the output
    • Top p (default: 1.0, range: 0-1.0) - Controls diversity via nucleus sampling
    • Top k (default: 0, integer ≥ 0) - Limits the cumulative probability of tokens
    • Frequency Penalty (default: 0, range: -2.0 to 2.0) - Reduces repetition based on frequency
    • Presence Penalty (default: 0, range: -2.0 to 2.0) - Encourages new topics
    • Repetition Penalty (default: 0, range: -2.0 to 2.0) - Penalizes token repetition
    • Max Tokens (optional, integer ≥ 1) - Maximum number of tokens to generate
