Replyflow is the Instagram comment to DM app for Shopify. Every buying comment gets a reply and a DM with the right product, a unique coupon and a one-click checkout link — in seconds.
Built inside Shopify · Billed through Shopify · Live in minutes

'Link?' 'Price?' 'Ships to California?' Your Reels are full of buyers. Replyflow replies publicly and sends each one a private DM with the product card and checkout link, so no sale gets lost in the comments.
Run 'Comment GLOW for 20% off' campaigns with instant keyword triggers, unlimited on every paid plan. Turn on AI to catch natural questions keyword bots miss. Hybrid does both: keywords first, AI for everything else.
Instant triggers for words like “LINK”, “PRICE” or “GLOW”. Contains, exact match, typo tolerance and negative keywords. Unlimited on every paid plan.
No preset keywords. AI spots buying intent and product questions like “Does this work on dry skin?” and answers from your store data.
Keywords first, with no AI cost. Anything that doesn’t match goes to AI, so no buyer gets missed.
Public codes end up on coupon sites. Replyflow creates a unique Shopify discount code for each commenter that expires in 48 hours — real urgency, protected margin.
The DM button opens your product page or checkout with the discount already applied. Your dashboard shows exactly how much revenue your comments generated.
