AI Copy/Paste/Upload Blocker

Tracking since Apr 19, 2026.

Changelog

• Jun 7, 2026
  description

  This extension is primarily intended for schools that are trying to embrace AI but also dissuade students from mindless cheating (or people who want to take more time when extracting data from AI). Basically it blocks the ability to copy and paste (and select text) from a list of AI sites. Probably not all at the moment, but I'll add more as I find them (or people send me them if there's one I missed). I work in a school and wanted to throw a speedbump at all the kids who would copy a question (from a quiz, test, essay, etc.) in to AI then take the answer and copy/paste it back. At least this way if they're really determined to get an answer from AI, at least they might learn a bit and think about it while they're having to type it all up.
  
  Feedback is welcome, except from angry students who now have to do more work. In that case, sorry/not sorry. Although I guess you can see by negative reviews that the software actually works and annoys students. Probably ones who need AI in order to make a comment.
  
  Admins can add custom entries for this extension the Windows registry by adding these example entries: 
  [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome\3rdparty\extensions\ohdnokamhlhcobcpebkconbepfomicoa\policy\AllowedSites]
  "1"="gemini.google.com"
  
  [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome\3rdparty\extensions\ohdnokamhlhcobcpebkconbepfomicoa\policy\CustomBlockedSites]
  "1"="youtube.com"
  "2"="ixl.com"
  
  Google Admin console example:
  {
    "AllowedSites": {"Value": [
      "gemini.google.com",
      "grammarly.com",
      "magicschool.ai"
    ]},
    "CustomBlockedSites": {"Value": [
      "ixl.com"
    ]}
  }

  Update 0.4.4: Added grammarly (exempt it using the steps above, if needed) and some more sites.
  Update 0.4.3: Added some more sites.

  Update 0.2: added a lot more AI sites, AI humanizer sites, as well as Google searches with udm=50 (AI mode).
