BuyWise — Buying Advisor

About

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.
