Quick questions about comment moderation tools
What is the cheapest tool that hides comments automatically?
Social Moderator AI's Plus plan, at €10 a month, is the cheapest plan with automatic hiding of the sixteen tools we compare. Next come CommentGuard at $29 a month, ReplyZen at $29 a month and MyComments.io at $29.99 a month. The full list is in what automatic hiding costs.
Is there a free comment moderation tool?
NapoleonCat and Agorapulse list free plans. NapoleonCat's automatic hiding needs its Expert plan, from $139 a month, and Agorapulse does not state what its free plan includes. Of the other tools on this page, Social Moderator AI offers a 15-day free trial and CommentGuard and TrollWall AI 7 days each. Respondology offers no trial, and Smart Moderation does not state one.
Do I need AI, or are keyword filters enough?
Keyword filters hide comments that contain the words you list. AI moderation classifies a comment by its meaning, so it does not depend on the exact wording. All six tools on this page state they use AI to classify comments, and most also let you add your own keyword filters.
Can these tools hide comments on ads?
All six list ad comment moderation. Social Moderator AI also covers ads that never appear on your Page, and TrollWall AI states it moderates dark posts. NapoleonCat moderates ad comments in its inbox from the Pro plan and hides them automatically on Expert, and Respondology lists paid social moderation from its Premium plan. More in ad comments at scale.

How Social Moderator AI works
Moderation rules are written in plain English
Rules are written as plain English lines or paragraphs, with no regex or decision trees, and each rule can say what to keep visible as well as what to hide. A draft can be run against recent comments to see what would be hidden, flagged or answered, and the page states that nothing changes on your pages until you publish. Every published version is kept so you can roll back. Rules apply to every page in a workspace, direct messages have their own rule set, and the site suggests separate workspaces when a brand needs different policies. A comment that matches no rule stays visible. Source
Every decision shows its rule, confidence and reason
Each action shows the matched rule, the confidence level and the reasoning in plain words. Comments the AI is unsure about are marked Needs review instead of being hidden, so a person decides. Any decision can be unhidden, approved or re-evaluated in one click, and both the action and the undo are recorded in a timestamped audit log that is available on every plan. The log records AI decisions, hides and unhides, likes and replies, and who or what performed each action, and can be filtered by action type, date range or page. Source
Reply drafts in a brand voice, with a draft mode first
You describe the brand, choose the reply language and add example replies, and the site says drafts follow your tone, your phrasing and the things you never say. One voice can cover a whole workspace, and individual pages can have their own. Draft mode requires approval of each reply before it is sent, and Auto mode sends only replies above a confidence threshold you set. On Pro and Agency you can add knowledge sources such as shipping, returns or opening hours, which the site says replies quote instead of guessing. Source
Five channels, including ads and DMs
The product covers Facebook Page posts, Reels, ads and Messenger; Instagram posts, Reels, ads and DMs; TikTok video comments, which the site says are checked every minute; YouTube channel comments, which move to the held-for-review queue in YouTube Studio when hidden; and Google Reviews, which get AI reply drafts on Pro and Agency. Facebook and Instagram comments are moderated within seconds through Meta webhooks, and ad comments appear in the same inbox as organic ones, filterable by page, post or status. Source
Free audit of recent comments, then a 15-day trial
The free audit scores the newest 50 comments from your 10 most recent Facebook posts against four starter rules, and the site says it takes about a minute, needs no card and changes nothing on your Page. The report gives four counters (would hide, would reply, flag for review, would like) and, for each comment, the verdict, the matching rule, the AI confidence and a one-line reason. It is read-only. Each workspace gets one audit and each Page can be audited once. A card is asked for only when you start the 15-day trial, and nothing is charged until the trial ends. Source
Plan limits are pages, AI actions and seats
Plus is 10 EUR per month billed monthly or 9 EUR billed yearly and covers 2 pages, 250 AI actions per month and 1 seat. Pro is 49 EUR monthly or 40 EUR yearly for 10 pages, 2,500 AI actions and 3 seats. Agency is 199 EUR monthly or 160 EUR yearly for up to 50 pages, 15,000 AI actions and 15 seats. Each moderation decision and each AI reply draft counts as one AI action, while viewing comments, hiding manually and editing drafts do not. Plus leaves out lead detection, Google Reviews, image and GIF moderation and political pages. Source
