DeAlter – Hide AI-Generated YouTube Videos

DeAlter hides YouTube videos that carry an "altered or synthetic content" disclosure — the label creators add when footage is AI-generated or significantly digitally altered — so they disappear from your feed as you browse. It works automatically the moment you install it. Flip it on or off from the toolbar, where a small counter shows how many it has hidden. • Filters the home feed, search, sidebar, and channel pages • Replaces each hidden video with a small placeholder instead of removing it, so the page never jumps or flickers • Reads each video's official disclosure — no guessing, no false flags on real footage • Remembers its verdicts, so browsing stays fast and light on requests • Private: everything runs in your browser. No accounts, no tracking, no servers. Note: DeAlter can only hide videos that are actually disclosed as altered or AI-generated. Undisclosed AI can't be detected from outside YouTube — by anyone.
