The Problem

Foreign language content is inaccessible; manual translation is disruptive

Current Solutions (Not Great)

Google Translate (whole page, loses context), manual copy-paste, skip foreign content

Who Needs This

International shoppers, news readers, language learners, global community participants

The internet is global but language barriers persist. Polyglot Comments automatically detects foreign-language comments, reviews, and posts and translates them inline—right where they appear, without disrupting the page. Unlike Google Translate, it preserves nuance, explains cultural context when relevant, and handles slang and idioms intelligently. Great for international product reviews, foreign news sites, or following discussions in other languages.

Honest Take

Google Translate is everywhere and free, so you're competing on quality (nuance, slang, cultural context) and UX (inline vs. full-page). LLMs are genuinely better at idiomatic translation than older tools, but monetization is tough—translation feels like it should be free. Maybe position as a premium tool for international business/shopping.

Build Prompt

Use this prompt with an AI assistant to start building

Build a Chrome extension called 'Polyglot Comments' using WebInfer. Manifest V3 with activeTab, storage permissions. Content script: find text blocks (comments, reviews, posts) via common selectors. Detect language (simple: character set analysis; or ask AI). For non-user-language text, translate. Use generateObject to return { originalLang: string, translation: string, confidence: number, culturalNotes?: string, idioms: [{ original: string, meaning: string }] }. Inject translation as styled div below original (muted color, smaller font, toggle-able). Show small flag icon indicating translation. Click translated text for detailed view with idiom explanations. MutationObserver catches new comments loaded dynamically. Settings: target language, sites to auto-translate, show/hide originals. Cache translations by text hash in chrome.storage.local. 'Translate selection' context menu for manual trigger.
