Every comment, on one line
Comment, rule, answer, result. Spam is hidden the moment it lands and costs nothing. A question gets its answer, with a link whose clicks are counted. A complaint goes to a person, with its whole thread.
We don’t model or estimate anything. A click counts when it lands on the answer’s own link, and only then.

Where ReplyZen is the better choice
If one of these is what you need most, ReplyZen is the better fit.
AI replies are the job
Contextual AI replies at scale, trained on your knowledge base, rather than moderation rules.
Reply-level click analytics
ReplyZen puts shortlinks with click and UTM tracking in its replies, the lighter thing to set up if per-reply clicks are all you want. Ours are counted on every answer too.
Confidence-based publishing
Hybrid mode publishes the replies its AI is sure of and queues the rest for review. A strong feature for reply-heavy teams.
Moving over takes about 7 minutes of your time
Connect the same accounts, pick starters, and leave them in watch mode next to ReplyZen until their log reads the way you want.

Questions people ask before switching
Something else? Ask us, book a demo, or read how we count.
Can I run both while I decide?
Yes. Leave ReplyZen replying and run our rules in watch mode on the same accounts. They record what they would send and send nothing.
Do I need to be selling anything?
No. Plenty of accounts come only to moderate: spam and abuse hidden, questions answered, the rest sent to you. Every answer’s tracked link counts its clicks, whatever it links to.
What counts as an automation?
One reply, private reply, DM or like that a rule sends, or one AI draft. Hiding is free, and anything you answer yourself doesn’t count. Base includes 1,000 a month, Pro 5,000 and Premium 25,000; extra ones are opt-in, at 5¢, 3¢ or 1¢.
Will it reply to something I didn’t expect?
Not by surprise. Any rule can run in watch mode, and starters begin there: it records what it would have sent and sends nothing. You can also hold a rule’s replies for approval, so nothing goes out until you approve it.
Which platforms does it work on?
Instagram and Facebook today: comments, DMs and private replies. TikTok, YouTube, X (Twitter), Reddit and Discord are coming.
What happens when the trial ends?
Nothing is charged, because we never asked for a card. Your rules pause and everything stays: rules, saved replies, settings, and your comments, readable on every screen. Choose a plan and the rules start again.
