BuyWise - AI Purchase Research Advisor

BuyWise is an AI buying advisor that lives in your browser's side panel and answers one question: should you buy this? Search any product — or open it on Amazon/Flipkart — and BuyWise reads real reviews and discussions, then gives you a clear BUY / CONSIDER / SKIP verdict with a confidence score, ranked pros and cons, community sentiment, a fake-review trust score, deals, and answers to your follow-up questions. WHAT MAKES IT DIFFERENT • Grounded, not guessed — every verdict shows exactly which sources it used (Reddit, YouTube, on-page reviews, the web) and an honest "grounded vs. AI-estimate" label, with clickable citations. • Reads the page you're on — on a product page, it uses the visible reviews, price, and rating to ground the verdict. No login, ever. • Computed trust score — real fake-review signals (duplicates, incentivized language, rating skew, verified purchases), not a vibe. • Deep Research mode — a multi-agent web search that plans, researches, fact-checks, and synthesizes. • Region-aware — currency and retailers for the US or India (more coming). PRIVATE BY DESIGN • No servers, no account, no tracking. Everything runs in your browser. • Bring your own OpenAI API key (and optionally a free YouTube key) — stored only on your device and sent directly to each provider, never to us. FREE & UNLIMITED No subscription. You only pay your own AI usage. REQUIREMENTS An OpenAI API key is required for live verdicts (add it in Settings). Reddit needs no key. Without a key, BuyWise runs in demo mode so you can explore the interface.
