CommentShield hides toxic comments and bot spam before they reach you — in your browser with our extension, or at scale for your whole platform with our filtering API.
Extension filtering is 100% on-device. No account required to start.
Link spam, crypto scams, and copy-paste floods caught by duplicate detection and behavior patterns.
Toxic comments fold into a "show anyway" bar. Nothing is removed from the platform — only from view.
Criticism with genuine suggestions is routed to a digest, readable whenever you choose.
The same engine, hosted. Send comments, get verdicts — pass, quarantine, hide, or block — with scores and reasons.
To subscribe, click Upgrade to Pro in the CommentShield toolbar popup. That links checkout to your browser, so Pro unlocks on its own once you pay.
To subscribe, click the upgrade button in the CommentShield toolbar popup. That links checkout to your browser, so Studio unlocks on its own once you pay.
Prices shown are launch placeholders — validate against comparable tools before going live.
Send up to 100 comments per request.
Each returns a verdict (pass, quarantine, hide,
block), a toxicity score, a bot score, and human-readable reasons.
Batch duplicate detection runs across each request.
Deterministic heuristics answer in <20ms; borderline cases can escalate to an LLM pass. Comments are processed in memory and never stored. Get a key on the Studio plan.

Enabled toggle at the top of the popup. Changes apply immediately, on every supported site. You can also switch individual sites on or off under Run on.Upgrade to Pro. It opens our pricing page linked to your browser; subscribe there through Stripe, and Pro unlocks in the extension on its own, usually within a minute or two. To cancel, use the link in your Stripe receipt email, or contact us and we'll help.Show anyway on the collapsed comment to read it — nothing is deleted, only collapsed. If it happens often, try lowering the strength to Relaxed in the popup (Pro), or let us know what got flagged so we can improve detection.Run on in the popup, and filtering runs on-device on all of them.Last updated: September 16, 2026
CommentShield ("the extension," "we," "us") is a browser extension that hides toxic comments and bot spam on YouTube, X (Twitter), Facebook and LinkedIn. This policy explains what data the extension does and does not collect, and how it is used.
CommentShield does all comment filtering locally, on your own device. We do not operate a server that receives your browsing activity, your comments, or the content of any page you visit. We do not sell, rent, or share personal data with third parties for advertising purposes.
The extension uses Chrome's local storage permission to save the following
information only on your own device:
None of this information leaves your device, is transmitted to us, or is accessible to any other website or extension — with one exception: the install ID, which is sent as described under "Payments and subscriptions" when you choose to upgrade or have upgraded.
Separately from the sites above, the extension contacts our license server only to ask whether this install has a paid plan, as described under "Payments and subscriptions."
On every site above, the analysis happens locally in your browser. Comment text, page content, and the addresses of pages you visit are never sent off your device. The extension reads only the comment areas of these sites, and only while you are on them.
If you choose to purchase the optional Pro or Studio plan, checkout is handled entirely by Stripe on our website. We never see or store your payment card details. Stripe collects the email address and payment details you provide at checkout under its own privacy policy.
To unlock your plan automatically, the extension works with a small license server we operate:
CommentShield is not directed at children and does not knowingly collect personal information from children.
If this policy changes, the "last updated" date above will be revised, and material changes will be reflected in the extension's Chrome Web Store listing.
