Where they win
Where ReplyZen is the better fit
We are not the right tool for everyone. If any of the below applies to your team, ReplyZen might serve you better than we will.
Strong AI-reply + conversion-tracking story
ReplyZen leans into sales-style AI replies with UTM and conversion tracking — a strong fit for advertisers who want to attribute revenue to comment replies.
Comment-to-DM and knowledge-base grounding
On-brand contextual replies grounded in a knowledge base, plus comment-to-DM automation, make it well suited to teams optimising for conversation-to-sale.
TikTok beta
Per its own site, ReplyZen has a TikTok beta — coverage beyond Meta that we do not offer in v1.
Our wedge
Where we believe ROAS Shield wins
Ad-first by design
Every comment in the inbox shows campaign, ad set, and ad context. You can filter by campaign, see which ads attract spam, and tune rules per-ad. Generic comment moderators do not foreground which ad a comment is on.
Volume pricing for paid-ads teams
Our Scale tier is £199 per month for up to 500,000 comments. Predictable, volume-based pricing for high-spend advertisers — not per-seat.
Honest UI on the rough edges
When we cannot map a comment back to its ad, we say so and surface a manual-mapping action — including an inverse creative lookup. We do not paper over Meta API gaps with confident-looking UI.

Pricing scales with comment volume, not seats. Start a 7-day trial without a card.
