Our intelligent engine scans every piece of user-generated content, ensuring that no profanity slips through the cracks. Our Image Moderation scanning technology also provides double the peace of mind by removing all inappropriate text from images.

Our filter platform goes beyond and understands nuance and meaning behind words.
We recognize that every project has unique community requirements, and our system is built to meet them. Trust us to provide you with the best profanity filtering solution on the market.

ProfanityBlocker is an efficient and nifty text and image moderation service with a Discord bot.
Go beyond blacklist/whitelist content filtering.

Filtering done your way

Since every project has different requirements around filtering accuracy and speed, we offer several types of filtering methods, giving you full control and flexibility.

Hybrid and InsightGuard Filter has a trainable custom model on top of the base model. You can help train the base model by reporting false positives (no filter is perfect) which will get reflected at our frequent incremental learning time – custom model too based on your own criteria (learn more about custom models here).

Filter models

Choose from many filtering models for complete flexibility.

Blacklist/Whitelist

We maintain the basic blacklist for typical bad language and you can customise what you classify as bad or good with your own blacklist/whitelist.  This filtering method is the least accurate out of all the filters, but is also the fastest.

Hybrid and InsightGuard Filter support custom training on content you add from the filter logs (request history).

Hybrid Filter

  • Binary Classification, trained on several classes of data including profanity, hate speech, sexual content, violence, racism and more.
  • Training de-duplication of datasets.
  • False positive reporting and learning capability on base model and client custom model. False positive validation before/after with mitigation techniques.
  • Incremental learning means it can train faster.
 

This method is a suitable middle-ground for most projects as it is more intelligent and faster than blacklist/whitelist at the expensive of no real understanding of meaning when it comes to understanding context (like InsightGuard Filter or DeepSense Filter types).

This might not matter for your use case if you need a faster auto moderating experience with slightly less accuracy than type InsightGuard Filter (and may block more seemingly bad words than InsightGuard Filter type words, as it just sees a potential bad word without understanding subtext. We train the Hybrid model with vast amount of bad language, bullying, sexualisation, hate speech, racism type content and more..

InsightGuard Filter

  • Binary Classification, trained on several classes of data including profanity, hate speech, sexual content, violence, racism and more.
  • Training de-duplication of datasets.
  • False positive reporting and learning capability on base model and client custom model. False positive validation before/after with mitigation techniques.
  • Vast knowledge of the English language, understands nuance/hidden meaning behind the words.
  • Incremental learning means it can train faster.
 
It’s designed to discern context, allowing it to differentiate when more mature language is used non-maliciously. This nuanced approach may permit certain mature expressions, depending on their context and intent, such as when they’re not used in an offensive or attacking manner.
 
This system is particularly suited for mature communities that engage in complex communication. It’s adept at identifying genuinely harmful content, which goes beyond mere swear words to include bullying, sexualization, hate speech, racism, and more.

DeepSense Filter

  • Multi-layered model: toxicity and up to 7 classes, word-level,  sentence classification capability.
  • Fine-tune your class  acceptability thresholds, per your community requirements.
  • Model bias mitigation training regime, multilingual (supporting 6 languages) capable.
    • English
    • Italian
    • Spanish
    • Russian
    • Portuguese
    • Turkish
  • Future capable of domain specific datasets to select additional language criteria for filtering.
 
This is ideal for mature communities that have more mature and complex communication where the real bad content isn’t just with your typical swear words, but bad language, bullying, sexualisation, hate speech, racism type content and more. 

Not sure which one to use?

We recommend starting with Hybrid as it is a good middle ground. You can always change your filter options and update/downgrade your filtering plan. if you run multiple servers, you can choose the right one for your audience.

Slack bot

Creating an inclusive environment is paramount to fostering a healthy relationship between members. Whether you are an open source community on Slack, or a business Workspace, our Slack bot, powered by our filters will help you nurture your Workspace:

  • We check messages the bot has been invited to
  • By default we nudge and encourage users to review flagged messages and edit it. It adds a visible reaction and comment on the message

By default, the Slack bot will not remove messages, we understand that each Slack Workspace has different requirements and policies around message retention.

If your Workspace permits extra privileges for the Slack bot, you can optionally provide a user token so that a “delete” button is available to problematic messages. With this token, additional functionality is available, like toggling automatic message deletion, instead of nudging users to modify their message.

How you choose to create an inclusive Workspace is ultimately up to your Workspace admins, we leave the choice up to you.

Privacy Disclaimer:

To ensure your Workspace privacy, you must add the bot to channels you wish to moderate. You can remove the bot from any channel and messages won’t be checked. Should you wish to moderate all public channels  in your Workspace you can toggle the auto join public channels.

We retain scanned content for no more than 30 days, allowing you the opportunity to train custom models per your Workspace requirements and refine your filtering experience.

We are currently exploring interest in this feature and would appreciate your feedback.

More on the Chromium Extension

We recognize the presence of unsettling content across various online platforms, including social media sites and blogs.

Our goal is to foster safer, more inclusive digital spaces, particularly on platforms like Discord, Reddit and Twitter/X that may lack automated moderation, by concealing NSFW material and explicit language.

Our content filters are customizable, allowing users to adjust sensitivity levels for various categories for an optimal browsing experience. Although not all administrators or owners of Discord servers, websites, forums, or blogs may choose to implement our moderation bot, we provide a viable alternative.

Our Chromium-based browser extension, in coordination with our filtering technology, scans web pages to blur content identified as inappropriate. This approach is designed to be minimally invasive, enabling users to view surrounding content and reveal the blurred content with a simple click if desired.

The extension is available for free to all users with an account, enhancing your browsing experience both within Discord and on the broader internet.

Privacy Disclaimer:

To ensure your privacy, you have the option to disable the plugin or utilize site exclusion settings for websites you prefer not to be scanned. We retain scanned content for no more than 30 days, allowing you the opportunity to train custom models and refine your filtering experience.

Parental controls:

Parents have the option to install our plugin on their children’s browsers for enhanced online safety. If you’re interested in a stricter setup, where blurred content remains hidden and the extension cannot be uninstalled by users, please contact us. We are currently exploring interest in this feature and would appreciate your feedback.

Other Disclaimer:

A typical browsing session can saturate the free plan within minutes, and the Pro plan should be sufficient for typical browsing, but this varies on how much text, and how many separate submissions are needed to be processed (e.g. larger block of text will require less hourly submissions compared with Reddit/Twitter/X posts with hundreds (or thousands) of comments and replies).

To ensure a smooth service and fair usage new plans might be required for extension usage given how many requests a typical browser session can make to our filtering service, and real-time filtering can be expensive at large volumes. Should you be subscribed to Pro or Ultima plans  at which point we decide we need new plans for extension usage only, we will try and match the old plan fairly at a grandfathered rate.

Not sure which filter to use?

We recommend starting with InsightGuard Filter. The browser extension will send a lot of text from webpages, for a faster result it is a good middle ground. You can always change your filter options and update/downgrade your filtering plan. if you want smarter filtering or category identification make sure to choose DeepSense Filter.
