What does ReplyZen do and what does it cost?
ReplyZen is an AI comment tool for Facebook, Instagram and TikTok that analyses each comment and decides whether to hide it or reply to it. The vendor positions it at advertisers and brands who want comments on their ads and organic posts handled without doing it by hand. Plans start at $29 a month, with a 14-day free trial. Source
ReplyZen strengths
- Moderates and replies to comments on Facebook, Instagram and TikTok, on paid ads as well as organic posts, from one inbox that filters by status, platform, tag, social profile and agent. Source
- Reads each comment with AI before acting: it analyses the post text, images and video, scrapes links in the post, can search the web, and judges the comment's intent and sentiment, then decides whether to hide it or reply. Source
- You choose how much runs by itself. With Auto-Publish off every AI reply waits as a draft for approval; with it on you pick All replies or High confidence, and the confidence bar is set to 50, 65, 80 or 95 percent. Source
- Public monthly prices on all four tiers from 29 USD per month, and the vendor says every tier includes all AI-powered features with unlimited agents, pages and team members. Source
- Detects the language of each comment and replies in that language, which the vendor says covers dozens of languages worldwide. Source
ReplyZen limitations
- Covers Facebook, Instagram and TikTok only, with no YouTube and no other network. TikTok is the most constrained of the three: hide only, no deleting other users' comments, no DM automation and replies capped at 150 characters. Source
- Every plan caps AI replies and moderations per month. The cheapest, Basic at 29 USD per month, covers up to 500 AI replies and up to 2,500 moderations, and the biggest listed tier, Ultra at 249 USD per month, covers up to 10,000 replies and 50,000 moderations. Source
- Moderation is driven by instructions written in natural language. The help center documents no keyword, phrase or blocklist field, so there is no plain word list to maintain or audit. Source
- The privacy policy says Hetzner hosts application servers in the EU, but it also says Vercel handles serverless functions globally, gives no location for Supabase or OpenAI, has no GDPR section, names no international transfer mechanism and states a retention period only for OpenAI, at 30 days.
