Watch with sound

The six Instagram comment moderation tools compared in this guide are ReplyMint, CommentGuard, BrandBastion, Respondology, Arwen.ai, and NapoleonCat. They span three pricing tiers: SMB-friendly tools ($0-$300/month), mid-market tools (custom pricing), and enterprise solutions (from about $1,000/month). If comment volume is the bottleneck, read how to bulk hide bad Instagram comments before you pick a vendor. ReplyMint is the strongest fit for D2C brands selling through Instagram and Facebook — its Instagram comment moderation tool handles both moderation and buyer intent detection in one inbox starting at $0. CommentGuard covers Facebook and Instagram posts, ads, and DMs with unlimited AI responses from $29/month (7-day trial, no free plan). BrandBastion, Respondology, and Arwen.ai target enterprise brands with custom-priced solutions. If you only care about paid posts, read how to stop spam comments on Instagram ads. Here's how they all compare, including which tools work for Threads.

Do these tools work for Threads?

Short answer: As of November 2026, ReplyMint, Respondology and BrandBastion are the tools in this guide with live Threads comment moderation.

Threads launched in 2023 and has grown rapidly, but comment moderation tool support remains limited. Here's the current state of Threads support across the six tools compared in this guide:

• Respondology — ✅ Supports Threads moderation (confirmed as of 2026)
• ReplyMint — ✅ Supports Threads moderation: spam detection, intent classification, and auto-hide in the same inbox as Instagram and Facebook. No Threads DMs, likes, or deletes.
• CommentGuard — ❌ Meta platforms only (Instagram and Facebook)
• BrandBastion — ✅ Threads comment moderation and keyword tracking (comments only, without DMs), alongside Instagram, Facebook, Messenger, TikTok, X, LinkedIn, YouTube and review sites
• Arwen.ai — ❌ Supports IG, TikTok, FB, X, YouTube — no Threads
• NapoleonCat — ❌ Supports 7+ platforms but Threads not listed
• replient.ai — ❌ Covers Meta, TikTok, LinkedIn, YouTube, and review platforms — no Threads

If Threads moderation is a requirement, there are three options in this guide. Respondology is the established, moderation-first choice, with human moderators across several networks. BrandBastioncovers Threads comments in its managed, quote-only service. ReplyMint puts Instagram, Facebook, and Threads comments in one inbox and adds buyer-intent detection, at SMB pricing. If Threads is a nice-to-have but not critical, the other tools in this comparison offer strong Instagram and Facebook coverage.

Why comment moderation matters specifically for sellers

Spam comments do not just clutter your feed — they actively undermine buyer trust at the moment it matters most. A product post with visible scam links, toxic replies, or aggressive competitor mentions tells a first-time visitor something about your brand before they have read a single word of your caption.

Comment moderation is a different priority for sellers than it is for publishers or media brands. For sellers, the comment section directly affects conversion — especially on ad posts where you are paying to amplify content and the comment section is visible to a cold audience who has never encountered your brand before.

The ad comment problem

Instagram and Facebook ads generate comment sections that are visible to everyone who sees the ad. Spam, scam links, and toxic comments in an ad thread erode the credibility of the post you are paying to run. Instagram's native Hidden Words filter does not apply to ad comments — meaning ad comment sections are unprotected without a third-party tool.

Keyword filters are not enough

Most basic moderation tools rely on keyword blocklists — you add words to block and the tool hides comments containing them. Spammers adapt quickly. New patterns slip through. Legitimate comments containing a blocked word get hidden by mistake. AI moderation reads the meaning of a comment rather than matching words, which makes it more accurate in both directions — catching more real spam and generating fewer false positives.

• Free trials: Only ReplyMint (free tier), CommentGuard (7 days), and NapoleonCat (14 days) offer risk-free testing

CommentGuard alternatives: When to look elsewhere

CommentGuard is a strong Meta-focused moderation tool starting at $29/month, but it's not the right fit for every brand. Here's when to consider alternatives:

Choose ReplyMint instead if:

You need buyer intent detection alongside moderation. CommentGuard hides spam but doesn't surface buyers — ReplyMint does both in one inbox. ReplyMint starts at $0 (free tier) vs CommentGuard's $29/month, and includes buyer intent classification that CommentGuard doesn't offer.

Choose BrandBastion instead if:

You need enterprise-grade accuracy (95%+) and optional 24/7 fully managed moderation service. BrandBastion offers custom AI models tailored to your brand, crisis detection, and human QA escalation — features CommentGuard doesn't provide. Pricing is custom (contact for quote).

Choose Arwen.ai instead if:

You need real-time automated removal across 5 platforms (Instagram, TikTok, Facebook, X, YouTube). CommentGuard only covers Instagram and Facebook. Arwen.ai removes comments in seconds without manual review queues. Pricing is custom (not publicly disclosed).

Choose Respondology instead if:

You need 24/7 US human moderators across Instagram, Facebook, TikTok, YouTube, LinkedIn, Threads and X (X on Premium and up). Respondology Moderate starts at $999/month billed annually (Basic, up to 10k comments a year); Premium, from $4,499/month, adds 100+ languages and paid social.

Choose NapoleonCat instead if:

You need a full social media management suite (scheduling, analytics, inbox, moderation) rather than dedicated moderation. NapoleonCat covers 7+ platforms with AI moderation on the Expert plan ($139/month). CommentGuard focuses on Meta moderation and AI replies without buyer-intent ranking.

For a detailed head-to-head comparison, see the CommentGuard alternative page.

BrandBastion alternatives: Enterprise options compared

BrandBastion is an enterprise-focused moderation platform with custom pricing and optional 24/7 managed service. Here's how it compares to other enterprise options and when to consider alternatives:

Choose Respondology instead if:

You need published pricing or human moderators on edge cases. Both cover more than Meta: BrandBastion covers Instagram, Facebook, Messenger, Threads, TikTok, X, LinkedIn and YouTube, plus review sites. Respondology supports 7 platforms including Threads, TikTok, YouTube, LinkedIn and X — with three-layer protection (keyphrases + AI + human moderators). Both are enterprise-priced, but Respondology has transparent starting pricing (from $999/month, Basic, billed annually) vs BrandBastion's custom quotes.

Choose Arwen.ai instead if:

You need automated real-time moderation without managed service. BrandBastion offers optional 24/7 fully managed moderation (Engage+ tier), which adds cost. Arwen.ai focuses on automated real-time removal across 5 platforms (IG, TikTok, FB, X, YouTube) without requiring a managed service team. Both have custom pricing.

Choose CommentGuard instead if:

You're a mid-market brand that doesn't need enterprise features. BrandBastion's custom pricing and managed service options are built for enterprise budgets. CommentGuard offers transparent pricing starting at $29/month with Meta-focused AI moderation — no annual contract or enterprise sales process required.

Choose ReplyMint instead if:

You're a D2C brand that needs buyer intent detection more than enterprise-grade moderation accuracy. BrandBastion specializes in brand protection and moderation. ReplyMint combines moderation with buyer intent detection — helping you close sales, not just hide spam. Starts at $0 (free tier) vs BrandBastion's enterprise pricing.

Enterprise vs SMB: Which tier is right for your brand?

The six tools in this comparison fall into three pricing tiers. Here's how to choose:

Rule of thumb: If you're unsure which tier, start SMB. ReplyMint (free tier), CommentGuard (7-day trial), and NapoleonCat (14-day trial) all offer risk-free testing. You can always upgrade to enterprise tools later if SMB options don't meet your needs.

Instagram ad comment moderation: which tools cover ads?

This is the section most moderation comparisons overlook. Instagram's native Hidden Words filter does not apply to ad comments. That means if you are running paid posts — boosted content, traffic campaigns, conversion ads — your comment sections are unprotected unless you have a third-party tool explicitly covering them.

All six tools in this comparison moderate ad comments through the Meta Graph API. But there are differences worth knowing. For Instagram ads, see how to stop spam comments on Instagram ads; for Facebook Pages and ads alone, see the best Facebook comment moderation tools.

CommentGuard

Ad comment moderation is a core use case for CommentGuard. The tool's own documentation specifically calls out ad comment sections as high-stakes — you are paying to amplify that content, and spam in the thread works directly against your conversion rate. Coverage applies to Facebook and Instagram ads across all plans.

NapoleonCat

Ads comment moderation is included on the Pro plan ($109/mo) and above. Standard ($89/mo) does not include ads comment moderation; Expert ($139/mo) adds AI auto-moderation.

ReplyMint

ReplyMint moderates Instagram ad comments with the same MintSense engine as organic posts, on all paid plans, without extra configuration.

ReplyMint's Instagram comment moderation tool ranks buyers while hiding spam in one MintSense pass. First scan in 2 minutes, starts at $0 (free tier), and there are no keyword lists to maintain.

Choose CommentGuard if:

Your primary need is Meta posts, ads, and DMs with transparent comment-volume pricing. CommentGuard starts at $29/month (5,000 comments) with unlimited AI responses on every plan, a 7-day trial, and no free tier. There is no Threads or TikTok coverage, and no buyer-intent inbox.

Choose BrandBastion if:

You're an enterprise brand on Instagram and Facebook evaluating Agent+, Reputation+, or Engage+ through a sales-led process. Pricing is custom quote only — request a demo rather than expecting self-serve checkout.

Choose Respondology if:

You need managed Moderate plans with 24/7 US human moderators across seven platforms including Threads. Moderate starts at $999/month billed annually (Basic); 100+ languages and paid social start on Premium, from $4,499/month. AI-crafted comment responses start on Standard, from $2,599/month.

Pricing is custom (not publicly disclosed). For a full Arwen alternative comparison for smaller brands, see ReplyMint vs Arwen.

NapoleonCat covers 7+ platforms with AI moderation on the Expert plan ($139/month). Built for teams and agencies managing multiple clients across many channels.
