How Filtering Works

SafePlay uses advanced technology to identify and filter profanity in YouTube videos.

The Process

1Request a supported public, embeddable YouTube video
2SafePlay prepares a language filter and shows its status
3The prepared filter uses SafePlay's standard list plus eligible custom words
4When ready, SafePlay mutes or bleeps selected moments during playback

What Gets Filtered

  • • Standard profanity and vulgar language
  • • Crude/offensive terms
  • • Your custom word list (paid plans)

What Doesn't Get Filtered

  • • Visual content, themes, or imagery
  • • Every possible offensive or inappropriate topic
  • • Unsupported languages
  • • Private, restricted, live, or non-embeddable videos

Processing Time

Preparation time varies by video length and service demand. SafePlay shows when filtering is ready; do not assume a pending video is filtered.

Detection Accuracy

Automated filtering has limits

SafePlay can miss a word or filter a harmless word. Review content when that matters.

What This Means

Filtering performance depends on the content. Misses are more likely with:

  • • Heavily accented speech
  • • Very fast speech
  • • Background noise interference
  • • Mumbled or unclear words

False Positives

Sometimes we might filter a word that sounds like profanity but isn't. This is rare, and we continuously improve our system to minimize these cases.

Reporting Issues

If you notice we missed something or incorrectly filtered a word:

  1. 1Go to your filtered video in History
  2. 2Click "Report Issue"
  3. 3Note the approximate timestamp
  4. 4We'll use this feedback to improve

Setting Up Custom Word Filters

Paid plans can add custom words to filter beyond the standard profanity list.

Adding Custom Words

  1. 1Go to Settings → Filter Preferences
  2. 2Scroll to "Custom Words"
  3. 3Add words or phrases, one per line
  4. 4Click "Save Changes"

Best Practices

  • •Be specific — adding "dang" won't filter "danger"
  • •Include common misspellings if needed
  • •Add phrases exactly as spoken (e.g., "oh my god")
  • •Test with a known video after adding

Per-Profile Custom Words

Each family profile can have its own custom word list. Go to Family → Select a profile → Edit Filter Preferences. This lets you use more restrictive settings for a Managed Profile while being more relaxed for teens.

Mute vs. Bleep: Which to Choose

SafePlay offers two filtering modes. Choose based on your preference:

Mute Mode

  • • Selected filter moments are muted
  • • Brief moment of no audio
  • • More subtle and natural-feeling

Best for: Adults who want minimal disruption

Bleep Mode

  • • Classic "bleep" sound replacement
  • • TV-style censoring
  • • Clear indication of filtering

Best for: Families who want to know when content is filtered

Note

Your current choice is used when SafePlay applies a ready filter. You can change mute or bleep in your filtering preferences.

What Videos Work with SafePlay

SafePlay supports public, embeddable YouTube videos that its services can prepare. Some videos are unavailable.

Commonly Supported

  • • Public YouTube videos
  • • Educational content
  • • Music videos
  • • Documentaries

Limited or No Support

  • • Private videos — not supported
  • • Age-restricted — not supported
  • • Live streams — not supported
  • • Region-restricted or embedding-disabled videos — unavailable where restricted

Checking Compatibility

The easiest way to check is to try filtering the video. If there's an issue, SafePlay will tell you before processing starts.

Re-filtering Videos

Sometimes you might want to re-filter a video you've already processed.

Reasons to Re-filter

  • • You've added new custom words and want them applied
  • • You want to switch between mute and bleep mode
  • • Our system has been updated with improved detection

How to Re-filter

  1. 1Go to History
  2. 2Find the video you want to re-filter
  3. 3Click the menu (three dots)
  4. 4Select "Re-filter Video"
  5. 5Confirm

Re-filtering is free

Once a video has been filtered, re-filtering or replaying it never counts against your trial budget or throttle limit.
