InfoBlend per Suhaib

InfoBlend turns any page into a richer reading surface.

🔎 DEFINITIONS
• Double-click any word for an instant tooltip with phonetics, pronunciation, examples, synonyms, and CEFR difficulty
• Select a phrase (2–5 words) for compound definitions from Wikipedia, Wiktionary, Dictionary, Datamuse, and Urban Dictionary
• Universal pronunciation: recorded native-speaker audio where available, browser TTS for everything else

🌍 TRANSLATION
• Right-click any selection to translate, in 17 languages
• Context-aware: passes the surrounding paragraph so idioms and ambiguous terms translate correctly
• Works without an AI key via a free fallback; better quality with your own Gemini or OpenAI key

📝 SUMMARIES
• Press Ctrl+K to summarize the current page in bullets or prose
• Right-click any selection to summarize just that text
• Read-time estimate of the original article so you know what you're saving

💬 CHAT WITH THE PAGE
• Type a question in the Ctrl+K palette (or prefix with "ask ")
• Strict grounding: the AI answers only from the page text and cites each source passage
• Verify every answer against the original quoted snippet

💾 KNOWLEDGE VAULT
• Save any definition, summary, or translation with the bookmark icon
• Browse, export to CSV or Markdown, take your data anywhere
• No account, no cloud, no email

🛠 PRIVACY-FIRST DESIGN
• No telemetry, no tracking, no servers we operate
• Bring your own API key (Gemini, OpenAI, or any custom endpoint) — never required, always optional
• Encrypted local storage for your AI key (AES-GCM, PBKDF2)
• Per-site disable list silences InfoBlend on hostnames you choose
• Cross-device sync for your preferences (your AI key stays local-only)

⚡ ERGONOMICS
• Light and dark themes with five accent colors
• Drag any overlay to reposition; pin overlays for side-by-side comparison
• Modifier-key trigger (Alt / Ctrl / Shift) to suppress accidental popups
• Full keyboard navigation with Ctrl+K command palette
• Shadow DOM isolation: page styles can't break our UI, and our UI can't break the page
