What gets caught
What gets stopped before it costs you a customer
You decide what does not belong under your posts. Everything matching is hidden from the public within seconds of arriving — on both platforms, without you watching the feed.
Spam links and contact drops
Scam URLs, coupon spam and the phone numbers and email addresses left under your ads to move a buyer off your page and onto someone else's funnel.
See the full Facebook filter list →Profanity and abuse
Slurs, vulgarity and hostile pile-ons in any language, judged by AI rather than a keyword list you keep guessing at. The AI stage is switched off for now: the filter is there to configure and starts acting when it ships.
See the full Instagram filter list →Whatever else you name
Your own keyword list, competitor mentions, hashtag stuffing, emoji replies, image comments — each one a switch, set per page, changed whenever you like.
Every filter is on every plan →Paid posts
Your ad's comment section is part of the ad
Facebook and Instagram give you a keyword list per page and little else — no rules that carry to your other accounts, no roles for staff or clients, no record of what was hidden and by whom. So the comment that undoes your ad sits there until someone notices.
The mechanism
How it works
A comment arrives, it is read against your rules, and a match is hidden — before most of your audience has scrolled past it.
Paste a comment and see which rule would catch it →
Connect your Page
Log in with Facebook once. The Instagram professional account linked to the Page comes with it. Nothing is ever posted on your behalf.
Pick your rules
Switch on what you want caught, add your own keywords, and whitelist the people who must never be touched. Rules are set per page, so no client inherits another's.
Leave it running
Every new comment on your posts and ads is checked around the clock. Nothing already on your page is touched — moderation starts at the moment you connect.
Plans
One thing changes as you grow: comment volume
Pages, team members and filters are unlimited on every plan, AI replies too once they land. The only line that moves is how many comments are processed each month.
