To keep unwanted text out of Streamlabs alerts, open Streaming essentials > Alert Box, then use the general settings to enable the profanity filter and add custom bad words or phrases. Save your changes and preview the result. For messages that need context-sensitive review, turn on alert moderation so alerts wait for approval before they appear.

Set up automatic word filtering in Streamlabs

  1. Sign in to Streamlabs and open Streaming essentials > Alert Box.

  2. In the Alert Box general settings, enable Profanity Filter. Add the words or phrases you want to block under the custom bad-words setting. Streamlabs describes using its standard list, a custom list, or both. See Streamlabs’ current alert setup guide.

  3. Choose how matching text should be handled. Streamlabs’ filter instructions describe censoring matching words or disabling alerts that contain them. Censoring can preserve the event notification while obscuring the word; disabling the alert can hide the entire notification, including a legitimate follow or subscription. The exact labels may change, so confirm the available behavior in your dashboard. See Streamlabs’ profanity-filter instructions.

Choose between filtering and approval

Approach Best for Trade-off
Automatic profanity and custom-word filtering Recurring terms you already know you want to censor or block. It does not provide human judgment about context; broad terms may affect innocent messages.
Alert moderation Unpredictable text where someone should review the message before it appears. A moderator must review held alerts, which adds work and can delay their display.

Streamlabs documents alert moderation that holds alerts for approval, with regular or unlimited approval-delay options in its setup instructions. Use it when a person needs to decide whether the wording is appropriate rather than relying only on a word list. See Streamlabs’ alert setup instructions. The available sources do not report measured accuracy or effectiveness for either approach.

Alert filtering is separate from live-chat moderation

A platform’s chat moderation controls do not necessarily filter text displayed by a third-party alert overlay. Streamlabs documents a filter for Alert Box text. YouTube separately provides a blocked-words list for live chat in YouTube Studio, while Twitch documents AutoMod and permitted or blocked terms for chat. Configure the control that matches where the text appears:

Or let it run in the cloud

StreamNeo serves a different purpose: it keeps a YouTube channel live from uploaded videos, not from a camera, and it does not filter alert text. The alert-filtering steps above remain the way to handle Streamlabs alerts. If you also want a pre-recorded video stream to keep running without a computer at home, StreamNeo works in three steps: upload a recording or build a playlist, add your YouTube stream key, and go live.
