LTK (formerly LikeToKnow.it) is one of the largest influencer commerce platforms. It gives creators a curated product link page (like a shoppable feed), brand partnership management tools, and affiliate commission tracking across 5,000+ retailers. It is free for creators — LTK takes a percentage of purchases made through creator links.
The catch: LTK is not a DM automation tool. It does not trigger DMs when someone comments on your post, does not send automatic replies, and does not integrate with Instagram's messaging API. The platform is built for product discovery and affiliate sales, not conversation automation.
Why people switch to CommentDM: They are not competing products. Creators use both: LTK to build shoppable product pages, and CommentDM to automatically send those pages to followers who comment 'LINK' or 'SHOP' on their posts. The combination — comment trigger + LTK URL in the DM — is a popular content format that drives both engagement and affiliate revenue.
LTK (LikeToKnow.it) is primarily a product link and affiliate commerce platform — it does not offer comment keyword triggers or automated DM flows. If someone comments 'LINK' on your Instagram post, LTK will not automatically DM them the product page. CommentDM does exactly this.
Yes, they serve different purposes and complement each other well. LTK manages your product link pages and affiliate tracking. CommentDM automates the delivery of those LTK links to followers who comment on your posts. Use LTK to create the link; use CommentDM to distribute it automatically.
LTK is free for creators (they take a revenue share on purchases). CommentDM costs $12/month after a 7-day free trial. The tools are not direct substitutes — LTK earns from sales commissions while CommentDM charges a flat SaaS fee for DM automation.
Creators caption a post with 'Comment LINK to get the full list' or 'Drop SHOP below and I'll DM you.' When followers comment the keyword, CommentDM instantly sends a pre-written DM containing your LTK page URL, affiliate link, or any other resource — automatically, 24/7.
Fashion, beauty, lifestyle, and food creators who regularly post links to products or guides. Also coaches and educators who offer free resources (PDFs, checklists, course previews) in exchange for comments — a format that drives algorithmic reach while building a DM list.
Pair your LTK links with CommentDM automation. Flat $12/month, 7-day free trial.
