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-$200/month), mid-market tools (custom pricing), and enterprise solutions ($1,500+/month). ReplyMint is the strongest fit for D2C brands selling through Instagram and Facebook — it handles both moderation and buyer intent detection in one inbox starting at $0. CommentGuard specializes in Meta-only moderation with transparent pricing starting at $29/month. BrandBastion, Respondology, and Arwen.ai target enterprise brands with custom-priced solutions. Here's how they all compare, including which tools work for Threads.
| Tool | Best for | Platforms | Buyer intent | Starts at |
|---|---|---|---|---|
| ReplyMint | D2C brands selling on IG/FB | IG, FB | ✅ Yes | $0 (Free) |
| CommentGuard | Meta-only moderation | IG, FB | ❌ No | $29/mo |
| BrandBastion | Enterprise w/ managed service | IG, FB | ❌ No | Custom |
| Respondology | Multi-platform enterprise | 6 platforms (incl. Threads) | ❌ No | $1,500/mo |
| Arwen.ai | Real-time auto-removal | 5 platforms (IG, TikTok, FB, X, YT) | ❌ No | Custom |
| NapoleonCat | Social media management suite | 7+ platforms | ❌ No | $79/mo |
Do these tools work for Threads?
Short answer: Only Respondology supports Threads moderation as of August 2026.
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 — ⏳ Threads on roadmap, not yet live
- CommentGuard — ❌ Meta platforms only (Instagram and Facebook)
- BrandBastion — ❌ Meta platforms only (Instagram and Facebook)
- Arwen.ai — ❌ Supports IG, TikTok, FB, X, YouTube — no Threads
- NapoleonCat — ❌ Supports 7+ platforms but Threads not listed
If Threads moderation is a current requirement, Respondology is the main option among established comment moderation tools. If Threads is a nice-to-have but not critical, the other tools in this comparison offer strong Instagram and Facebook coverage with more SMB-friendly pricing.
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.

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 detectionalongside 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 multi-platform moderation including Threads with human moderators. Respondology supports 6 platforms (Facebook, Instagram, TikTok, YouTube, LinkedIn, Threads) with three-layer protection: 30K+ keyphrases, generative AI, and 1,000+ U.S.-based human moderators. Starts at $1,500/month (enterprise-only).
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 ($119/month). CommentGuard is moderation-only.
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 multi-platform coverage beyond Meta. BrandBastion focuses on Instagram and Facebook. Respondology supports 6 platforms including Threads, TikTok, YouTube, and LinkedIn — with three-layer protection (keyphrases + AI + human moderators). Both are enterprise-priced, but Respondology has transparent starting pricing ($1,500/month) 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 detectionmore 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:
SMB Tier ($0-$200/month)
Tools: ReplyMint ($0-$79/mo), CommentGuard ($29-$199/mo), NapoleonCat ($79-$119/mo)
Choose if:You're a D2C brand, creator, or small agency managing 1-10 accounts. You need transparent month-to-month pricing, free trials, and self-service setup. Instagram and Facebook coverage is sufficient. You don't need managed service or custom AI models.
Mid-Market (Custom Pricing)
Tools: BrandBastion (custom), Arwen.ai (custom)
Choose if:You're a growing brand with complex moderation needs. You need custom AI models, higher accuracy guarantees, or real-time automated removal. You're managing 10-50 accounts or high-volume ad campaigns. Budget is flexible but you want to avoid enterprise-tier annual contracts.
Enterprise ($1,500+/month)
Tools: Respondology (starts $1,500/mo), BrandBastion Engage+ (custom)
Choose if:You're a large brand or agency managing 50+ accounts, massive comment volume, or multi-platform campaigns. You need human moderators (not just AI), 24/7 managed service, or Threads support. You have dedicated social media budget and require annual contracts with SLAs.
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.
The ad comments problem: what most sellers miss
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 three tools in this comparison moderate ad comments through the Meta Graph API. But there are differences worth knowing:
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
Instagram ads moderation is available on the Pro plan and above. If you are on the Standard plan (~$27/month), ads moderation is not included — you need to upgrade to Pro (~$64/month) to cover ad comment sections.
ReplyMint
ReplyMint moderates ad comments using the same MintSense AI engine as organic posts. There is no separate plan required — ad comment coverage is included across all paid tiers. The moderation fires on Instagram and Facebook ads without additional configuration.
Which tool fits your situation
Choose ReplyMint if:
You're a D2C brand selling through Instagram and Facebook and need moderation and buyer intent detection in the same inbox. ReplyMint is the only tool in this comparison that identifies buyers while hiding spam — MintSense handles both in one classification pass. Setup takes about 8 minutes, starts at $0 (free tier), and there are no keyword lists to maintain.
Choose CommentGuard if:
Your primary need is dedicated comment moderation for Facebook and Instagram with transparent pricing. CommentGuard specializes in Meta-only moderation starting at $29/month. The unlimited pages and team members on all plans make it cost-effective for agencies managing multiple client accounts. All plans include AI moderation and AI-generated reply suggestions.
Choose BrandBastion if:
You're an enterprise brand needing 95%+ accuracy AI moderation with optional 24/7 fully managed service. BrandBastion offers custom AI models tailored to your brand, crisis detection and real-time alerts, and three service tiers (automated, AI-assisted, fully managed). Pricing is custom — contact for quote. Best for brands with dedicated social media budgets and complex moderation requirements.
Choose Respondology if:

Respondology supports 6 platforms (Facebook, Instagram, TikTok, YouTube, LinkedIn, Threads) with three-layer protection: 30,000+ curated keyphrases, generative AI, and 1,000+ U.S.-based human moderators available 24/7/365. Starts at $1,500/month (enterprise-only, billed annually).

Frequently asked questions
What is the best Instagram comment moderation tool in 2026?
For D2C brands selling through Instagram and Facebook, ReplyMint is the strongest fit — it handles both moderation and buyer intent detection in one inbox, starting at $0. For pure comment moderation on Facebook and Instagram, CommentGuard is a well-regarded specialist option starting at $29/month. For enterprise brands needing 24/7 managed service, BrandBastion offers custom-priced solutions. For teams managing 6+ social platforms, Respondology starts at $1,500/month.
Are there tools that moderate Threads comments yet?
Yes. Respondology supports Threads moderation as of 2026. ReplyMint has Threads on the roadmap but it is not yet live. CommentGuard, BrandBastion, Arwen.ai, and NapoleonCat focus on Instagram and Facebook and do not currently support Threads. If Threads moderation is a requirement, Respondology is currently the main option among established comment moderation tools.
What are the best CommentGuard alternatives?
ReplyMint ($0-$79/mo) if you need buyer intent detection alongside moderation. BrandBastion (custom pricing) if you need enterprise-grade accuracy and optional 24/7 managed service. Arwen.ai (custom pricing) for real-time automated removal across 5 platforms. NapoleonCat ($79-$119/mo) if you need multi-platform social media management. CommentGuard specializes in Meta-only moderation, so alternatives depend on whether you need additional platforms or features.
What are the best BrandBastion alternatives?
Respondology (starts $1,500/mo) for enterprise-grade moderation across 6 platforms with human moderators. Arwen.ai (custom pricing) for real-time automated moderation without managed service. CommentGuard ($29-$199/mo) for Meta-only moderation at transparent pricing. ReplyMint ($0-$79/mo) if you need buyer intent detection for D2C brands. BrandBastion is enterprise-focused with custom pricing and managed service options, so alternatives depend on budget and platform needs.
Does Instagram have built-in comment moderation?
Yes, but it is limited. Instagram's native Hidden Words filter covers basic keyword blocking on organic posts. It does not cover ad comments, does not understand context, and requires manual updates as spam patterns change. Third-party tools connected via the Meta Graph API provide more reliable coverage, including for ad comments.
Can comment moderation tools work on Instagram ad comments?
Yes, when the tool uses the Meta Graph API. Instagram's native filter does not cover ad comments. All tools in this comparison (ReplyMint, CommentGuard, BrandBastion, Respondology, Arwen.ai, NapoleonCat) moderate ad comments through the official Meta API.
How much do social media comment moderation tools cost?
SMB-friendly tools: ReplyMint ($0-$79/mo), CommentGuard ($29-$199/mo), NapoleonCat ($79-$119/mo). Enterprise tools: Respondology (starts $1,500/mo), BrandBastion (custom pricing), Arwen.ai (custom pricing). Pricing typically scales by comment volume, number of accounts, or ad spend. Enterprise tools often require annual contracts and custom quotes.
What is the difference between keyword moderation and AI moderation?
Keyword moderation hides comments containing specific words you define. It misses spam that avoids your keywords and can hide legitimate comments that contain a blocked word out of context. AI moderation reads the meaning of a comment — understanding context, intent, and sentiment — so it catches what keyword filters miss without generating as many false positives.
Do I need a separate tool for moderation and auto reply?
Not necessarily. CommentGuard, BrandBastion, and NapoleonCat focus primarily on moderation with optional AI reply features. ReplyMint handles both moderation and buyer-intent-aware auto reply in one inbox, which reduces the number of tools sellers need to manage.
What tools do big brands use to moderate Instagram comments?
Enterprise brands typically use BrandBastion (custom-priced with 24/7 managed service), Respondology (starts $1,500/mo with human moderators), or Arwen.ai (custom-priced real-time moderation). These tools offer higher accuracy, dedicated support, and managed service options that justify enterprise pricing.
Is Respondology or BrandBastion better for comment moderation?
Respondology supports 6 platforms (including Threads) with three-layer protection (keyphrases + AI + human moderators) starting at $1,500/mo. BrandBastion focuses on Instagram and Facebook with 95%+ accuracy AI and optional 24/7 fully managed service (custom pricing). Choose Respondology for multi-platform coverage and human moderation. Choose BrandBastion for Meta-focused moderation with managed service and crisis detection.
What comment moderation tools support multiple languages?
Respondology: 28 languages with human moderators. BrandBastion: 100+ languages with custom AI models. Arwen.ai: 30+ languages with real-time moderation. NapoleonCat: Multiple languages on Expert plan. CommentGuard: All languages with AI. ReplyMint: All languages with MintSense AI. Most modern AI moderation tools support multilingual moderation, but enterprise tools (Respondology, BrandBastion) offer the widest coverage.
