Commentify: Customer Comments

One of the best comment apps, but with one caveat: commenters must log in (via Shop account or email). Clicking "add comment" opens a new tab prompting user to log in to your store. You could enable the anonymous option, but they won't get reply alert emails if don't login/register. This increases friction against engagement.

However, I like:
-Can use with FlowMail (from same dev) and Shopify Flow to auto-email commenters when someone replies. (new feature Feb 2026)
-Supports collapsable threads, markdown formatting (hyperlinks, bolding, etc), image upload, upvote/downvote.
-Supports import/export comments. Though import is handled by dev and costs $49.99 one-time fee. Some other apps allow importing CSV at no cost, but you'd need to format it correctly yourself.

The tool is easy to use. Wish there were no customization options though. the response time is great and they get your problem solved in no time! Keep up the good work!
