KEY FEATURES:

🤖 AI Content Detection & Credibility Scoring
Get two instant scores for any content: an AI Probability score (how likely it was AI-generated) and a Trust Score (how credible the source is). Four color-coded levels make results scannable at a glance.

🛡️ AI Verify — Fact-Check Any Article
Extract and verify claims from any webpage, PDF, or YouTube video. Each claim shows a verification status (Verified, Questionable, Unverified, False), detailed reasoning, and source references. Know what to trust before you share.

📄 Analyze Webpages, PDFs, and YouTube Videos
One extension handles it all. Open a webpage, a local PDF, or a YouTube video — Better Summarize extracts the content and delivers a structured summary, AI detection, credibility assessment, and verified quote highlights.

⏱️ Reading Time & Summary Length
See the estimated reading time before diving in. Control how detailed your summaries are — Concise for quick scans, Standard for balanced coverage, Detailed for deep dives.

💬 Chat With Your Content
Ask the AI follow-up questions about the article, PDF, or video. Get contextual answers with full conversation history. Type "regenerate" to re-analyze or "clear history" to start fresh — works in English, Chinese, and Japanese.

📝 Verified Quote Highlights
Every highlighted quote is extracted verbatim from the source text and verified client-side. No hallucinated citations — what you see is what the author actually wrote.

🖥️ Floating Window or Side Panel
Click the extension icon to open your preferred view. The draggable floating window stays on top for multitasking; the Chrome Side Panel gives you a dedicated workspace. Results and chat sync across both.

🔌 Three AI Providers, One Interface
OpenAI (GPT-5.4 Nano / Mini / 5.4) · Google Gemini (2.5 Flash / 3 Flash / 3 Pro) · Anthropic Claude (Sonnet 4.6 / Opus 4.6). Each provider remembers your preferred model independently. See per-analysis cost estimates in the tooltip.

⌨️ Keyboard Shortcut & Auto-Analyze
Press Ctrl+Shift+S (Cmd+Shift+S on Mac) to analyze instantly. Or enable Auto-Analyze to let the extension work automatically on every page you visit — zero clicks needed.

✨ Instant Selection Analysis
Select any text (120+ characters) on a page and a floating "Summarize" button appears. Or right-click and choose "Better Summarize Selection" from the context menu. Analyze just the part that matters.

📊 History Dashboard with Trends, Stats & Export
Your full analysis history with a statistics panel, 30-day trend chart, and top sites ranking. Filter by model, AI% range, or date. Bulk select and delete entries. Export to JSON, CSV, or a shareable HTML report.

🎛️ Custom Prompts
Create and manage your own analysis prompts with template variables ({{URL}}, {{TITLE}}, {{CONTENT}}, {{SELECTED_LANGUAGE}}). Customize the summary style while the system handles the technical logic.
