Which AI comment moderation tool handles many languages and keeps data in the EU?
TrollWall AI fits best if your data must stay in the EU: it states all data is stored on EU-based infrastructure and lists 19 to 20 languages. NapoleonCat processes EU and UK users' data in the EEA, and Agorapulse hosts data in AWS Ireland. Social Moderator AI reads any language but may process data outside the EU, so it is not our pick here.

How to choose
- Ask where comment data is stored and processed. Some vendors state an EU location, some state none, and some say data may leave the EU. Treat “not stated” as a question for the vendor, not a yes.
- Check languages on the plan you will buy. Language support is often a plan feature. TrollWall AI’s Starter plan covers one language, and Respondology’s multilingual support starts on Premium.
- Test in your own languages. A language count tells you little about slang and local insults. Run a trial or an audit on your own pages before you commit.
Questions about languages and EU data
Why is Social Moderator AI not the pick on this page?
Its privacy policy says data may be processed in countries outside your own, including the United States, and names no EU-only hosting. If EU data storage is a requirement, TrollWall AI, NapoleonCat and Agorapulse state EU processing, and Replient.ai lists EU hosting.
Which languages does TrollWall AI list?
Its FAQ lists Czech, Slovak, Polish, Hungarian, German, Spanish, French, Italian, Portuguese, Dutch, Romanian and others. Its homepage says 19 languages and its FAQ says 20.
Does EU data storage make a tool GDPR compliant?
Not on its own. Where data is stored is one part of GDPR. Ask each vendor for its data processing agreement and its list of subprocessors.
Which tools list the most languages?
BrandBastion lists 194 language entries for classifying and tagging comments, Bodyguard states 46 languages, six of them premium, and TrollWall AI 19 to 20. Social Moderator AI states its AI reads any language. Neither BrandBastion nor Bodyguard states EU-only hosting.
How we checked
Every price and feature on this page comes from the vendor's own website, and each one links to the page it came from. We record the date we checked it and re-check every tool at least every 60 days. Where a vendor does not say something, we mark it as not stated rather than guess.
We did not run our own tests on these tools, and we give no scores or star ratings. Read how we work.
Social Moderator AI
States its AI reads and moderates comments in any language, but rules must be written in English and its privacy policy says data may be processed outside your country, including the United States.
Social Moderator AI is a comment moderation tool that hides spam and abuse and drafts replies on Facebook Pages, Instagram, TikTok, YouTube and Google Reviews, built for brands, creators, politicians, sports clubs, news media, e-commerce and agencies. Source

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
