      How it works

      A mountain of comments in. One line that sells out.

      Four steps, from the open page to the ad. The examples use an invented greens powder brand.

      Open a thread, a product or a video.

      Reddit threads, Amazon listings, TikToks, App Store pages, Trustpilot. If people talk about it there, Comment Downloader can read it.

      Beta sources are not yet tested end to end. Etsy, eBay, Tripadvisor and Quora read only what the open page publishes, usually the first page.

      Comment Downloader reads every comment and review on the page in your own browser, the way you would. No API keys.

      The report

      Every finding comes with its quote.

      Miners send ore to an assay to learn what it is worth. Comment Downloader does that for comments: what repeats, how often, and the exact words.

      Ranked by what repeats

      The report opens with ranked ideas to test, so you start with what buyers say most.

      Checkable, line by line

      Each finding links to the quotes behind it, and each quote to the post it came from.

      Before you install

      Does my data leave my browser?

      Collecting happens in your browser and stays there. Only when you ask for a report is that collection's text sent to our server to write it. When you use Comment Downloader from an AI assistant, the collection is also kept on our server for 7 days so the assistant can read it.

      How do I use Comment Downloader inside Claude or ChatGPT?

      Add a custom connector with the address https://quoteminer-server.vercel.app/mcp and sign in with Google, using the same account as your Comment Downloader extension. Then ask in plain words. The assistant asks your extension to collect, so Chrome needs to be open. Custom connectors in ChatGPT depend on your ChatGPT plan.

      Do I need a Reddit, TikTok or Meta API key?

      No. Comment Downloader reads the same pages you can open yourself, in your own browser.

      Is it safe for my Facebook or Instagram account?

      It reads one post at a time, slowly, only when you start it. Meta does not allow automated collection, so no tool can promise an account is risk free.

      Which sources need me to be signed in?

      Amazon shows reviews only to signed-in shoppers, so sign in to Amazon in the same Chrome. Facebook and Instagram are read with your own session, and X shows replies only when you are signed in. Google Maps shows 5 reviews unless you are signed in to Google. Reddit, YouTube, TikTok, Trustpilot, the App Store, Google Play and most others need no login.

      What does beta mean for Etsy, eBay, Tripadvisor, Quora and X?

      These sources are not yet tested end to end. Etsy, eBay, Tripadvisor and Quora block automated reading, so Comment Downloader reads only what the open page itself publishes, usually the first page. If a site shows a human check, Comment Downloader stops and tells you.

      How is this different from a comment exporter?

      An exporter gives you a spreadsheet. Comment Downloader gives you that too, plus the pains, objections, angles and hooks inside it, each linked to the quotes behind it.

      What does it cost?

      Collecting is free and unlimited. The free plan includes 5 AI reports a month, 3 brands and 3 listening phrases. Paid plans with more reports are coming.
