Why channel-level

One video can hide it. A whole channel can't.

A single clip might pass as human. Twenty uploads in, the pattern gives it away.

Legit reads the whole channel: how it writes, how it sounds, how it looks, how it acts, how it's run. Then it judges every new upload against everything before it. A one-shot detector sees a single video in isolation. We see the fingerprint across all of them. Much harder to game.

How it works

70+ identifiers, five signals, two questions.

Five signals, composed of over 70 identifiers, answer two separate questions about every channel.

A How it's made · is the content AI-made?
01 / TEXT

What it writes

Transcripts, titles and descriptions, read for patterns consistent with AI writing. Feeds the authorship read.

02 / AUDIO

What it sounds like

Cloned voices, synthetic narration, robotic TTS. Feeds the authorship read. Often fills in over time.

03 / VISUAL

What it looks like

Thumbnails and frames, checked for the fingerprints generative models leave behind. Feeds the authorship read.

B How the channel is run · is it run like a content farm?
04 / BEHAVIORAL

How it acts

Upload cadence, comment patterns, community signals. Is this run like a content farm?

05 / OPERATIONAL

How it's set up

Channel age, verification, history and public metadata. A legit operation, or farm-like?

What you see

Two reads. No single verdict.

We don't boil a channel down to a single score. Those two questions stay two separate reads, each scored on its own with the signals behind it, so a clear answer on one never gets averaged away by the other.

How it's made
HumanAI
How strongly the signals point to AI, read from text, audio and visual. Not a measure of how much of the video is AI.
How it's run
LegitFarm-like
Whether the channel operates like a legit account or a content farm. Read from channel age, upload volume, community and history.
AI Slop

When both reads land at the same end, AI-made content on a farm-like channel, that combination is what we call AI Slop. It's the two reads agreeing, not a separate score.

Mixed Signals

Some signals come back clear. When one is unclear, we say Mixed Signals. When one is missing, we say that too. We never fill a gap with a guess, or read an unknown as human.

Why not just trust YouTube's labels?

YouTube only flags what it can watermark, and has every reason not to look harder.

YouTube does auto-label some AI now, but mostly when it can see a watermark or provenance tag from its own tools, Veo, or its partners, or spot obvious photorealistic AI. Use a different generator, strip the watermark, let AI write the script, or simply run a low-effort farm, and there's nothing to label.

And there's a conflict of interest baked in: YouTube is owned by Google, the same company building the AI tools creators use, like Veo and Gemini. It earns ad revenue when AI content runs, keeps 100% of the money when it demonetizes, and sets the labeling threshold inside a black box no one can audit. The safe move for its business is to under-report AI, which is exactly why an independent read matters.

Legit doesn't wait for a watermark. We read what's public across a whole channel, and we answer the second question too: is this run like a content farm? YouTube's label is a data point, not the answer.

YouTube's own label

  • Fires mainly on watermarked or tagged assets
  • Focused on photorealistic AI video
  • Per-video: watermarks can be stripped
  • Says nothing about farm-like channels
  • Owned by Google, maker of Veo and Gemini
  • Profits whether AI runs or gets demonetized

Legit

  • Independent: reads what's public
  • 70+ identifiers feed into five distinct signals across the whole channel
  • Every read shows its receipts
  • Answers the farm question too
  • No ad business and no AI models to push
  • No financial stake in the verdict
