The Basics
What is comment selling?
Comment selling turns the comment section of a social broadcast into the checkout. During a live shopping stream, every product carries a short code on screen. A viewer who wants it doesn't hunt for a link — they type a keyword and the code, right where they're already watching and chatting.
That matters because buy-intent comments are the most perishable traffic there is. "How do I order?" written under a live video converts if it's answered in seconds — and evaporates if it isn't. Comment selling automates that answer: a public reply confirms the order on the stream (which nudges everyone else watching), and a private message delivers the checkout link straight to the buyer.

How It Works
From comment to checkout
in three steps
02
Every product gets a code on screen
Stremify renders your catalog into a branded live stream where each product carries its shop code, price, and discount — so viewers always know what to type.
03
Comments turn into orders
A viewer types "SHOP 42". Stremify replies publicly, sends the checkout link privately, tags it with UTM parameters, and the order appears in your dashboard in real time.
Platforms
One keyword, two platforms
The same integration powers comment selling on both Meta platforms — and the stream itself can simulcast to YouTube, TikTok, and Twitch at the same time.
Built In
Everything comment selling needs
Your keyword, your script
Pick the trigger word and customize the public reply and CTA per campaign — the automation sounds like you.
Public reply + private link
The on-stream reply builds social proof; the DM or Messenger card carries the buyer straight to checkout.
Tracked end-to-end
Every link is UTM-tagged, so each order traces back to the exact stream, product, and comment that made it.
Orders in real time
Comment-to-buy orders land in your dashboard the moment they happen — watch the live convert while it runs.
Comment selling FAQs
What is comment selling?
Comment selling is selling products directly through the comments of a social media broadcast. Instead of pushing viewers to a bio link or an external shop, they type a keyword and a product code — like "SHOP 42" — under your live stream, and the sale is handled from there: an automatic reply confirms the order and a private message delivers the checkout link.
How does comment selling work with Stremify?
Every product in your live stream carries a shop code on screen. When a viewer comments your keyword plus the code (for example "SHOP 42"), Stremify replies publicly under their comment and sends them a product card with a checkout link privately — by DM on Instagram, by Messenger on Facebook. No typing on your side, no missed comments.
Which platforms support comment selling?
Stremify runs comment-to-buy on Instagram Live and Facebook Live. The same campaign can simulcast to YouTube, TikTok, and Twitch as well, but the automatic comment replies and private checkout links work on your Instagram and Facebook broadcasts.
Do my buyers need an app or an account?
No. Buyers just comment — the reply and the private checkout link arrive inside the platform they are already using, and the link opens the product page on your own store. There is nothing to install and no marketplace account to create.
Can I customize the keyword and the replies?
Yes. You choose the trigger word (SHOP, BUY, or anything else) and can customize the public reply and the call-to-action per campaign, so the automation still sounds like your brand.
How much does comment selling with Stremify cost?
Comment-to-buy is built into Stremify. The platform is credit-based: you buy streaming credits and pay only for the minutes you stream. There is no subscription, and every new account gets free credits to try it out — no credit card required.
