AI Script Detector for YouTube — Robot-Score Checker
The Robot-Score checker is a free AI script detector built for YouTube creators. Paste any AI-written script — English, Hindi, or Hinglish — and it returns a 0-100 Robot Score across four spoken-word tells: uniform sentence rhythm, hollow-authority filler, the Hook→3-points→CTA template, and web-blog connectors. It runs entirely in your browser; nothing is uploaded.
How it works
Under a minute from paste to fix list. Unlike a generic AI content detector, it scores how your script will sound on camera, not whether the prose was machine-written.
- 01
Paste your AI script
Drop in any script ChatGPT or another AI wrote — English, Hindi, or Hinglish. Scoring runs entirely in your browser; nothing is uploaded to a server.
- 02
Read your Robot Score
Get a 0-100 score (0 human, 100 robotic) plus a sub-score for each of the four spoken-word tells, with the exact filler and template phrases flagged in your text.
- 03
Fix the flagged tells
Vary sentence length, cut hollow-authority filler, break the Hook→3-points→CTA template, and swap essay connectors for words you actually say on camera.
- 04
Re-test, then lock your voice
Paste the revised script and watch the score drop. To stop fixing every draft by hand, lock a Tone Fingerprint so scripts ship human from the first draft.
Why AI YouTube scripts sound robotic when spoken
AI-written YouTube scripts sound robotic because large language models are trained mostly on written prose — corporate blogs, news articles, documentation — so their default output carries four measurable written-text tells. First, uniform sentence length: natural speech is bursty, mixing 3-word punches with 25-word runs, while raw AI output clusters tightly around 15-20 words per sentence. Second, hollow-authority filler such as "experts agree" and "in today's digital landscape" — phrases that carry zero retention value on camera. Third, the rigid Hook→3-points→CTA template viewers have now heard thousands of times. Fourth, web-blog connectors like "furthermore", "moreover", and "in conclusion" that almost nobody says out loud. Generic text detectors such as GPTZero, Copyleaks, and QuillBot score written prose; they do not measure whether a script will sound AI when performed. A spoken-word check scores exactly these four tells — including inside Hinglish scripts, where English filler hides between Hindi lines.
How to humanize an AI YouTube script
A better prompt won't fix it — the model always drifts back to its blog-trained default. The durable fix is structural: break each tell the score flags, then lock your own voice so drafts start human. Read the full breakdown of the four robot tells and their fixes. If your channel mixes Hindi and English, see which AI handles Hinglish scripts best in 2026. And if you're worried about the policy side, here's what YouTube's 2026 AI monetization policy actually allows and bans.
How JustShoot keeps scripts human
The Tone Fingerprint extracts your channel's rhythm, hook style, language mix, and signature transitions from your past videos, then writes every script inside that profile — so the four robot tells never get a chance to show up.

Frequently asked questions
Is this AI script detector for YouTube really free?
Yes — the Robot-Score checker is free with no sign-up and no card. Scoring runs entirely in your browser, so your script never leaves your machine. Only the deeper de-robot checklist (the line-by-line fixes for each tell) is free in exchange for an email.
How is this different from GPTZero, Copyleaks, or other AI content detectors?
Generic detectors like GPTZero, Copyleaks, QuillBot, Scribbr, and Grammarly's AI detector estimate the probability that written prose was machine-generated. They don't measure whether a script will SOUND robotic when spoken on camera. Robot-Score is spoken-word specific: it scores sentence-rhythm burstiness, on-camera filler, template structure, and essay connectors — the retention killers — and it handles Hinglish scripts, which generic text detectors routinely mis-score.
What are the four robot tells it checks?
Uniform sentence length (low burstiness), hollow-authority filler ("experts agree", "in today's digital landscape"), the rigid Hook→3-points→CTA template, and web-blog connectors you never actually say out loud ("furthermore", "moreover", "in conclusion"). Each tell gets its own sub-score, and the exact offending phrases are highlighted in your script.
Does it work for Hinglish and Hindi scripts?
Yes. The rhythm and template checks are language-agnostic, and the filler and connector checks catch the English phrases AI defaults to even inside a Hinglish script — which is exactly where robotic tells hide between Hindi lines. No generic AI content detector handles this spoken Hinglish case.
Will YouTube penalize my video if the script was written by AI?
Not for AI assistance itself — YouTube's 2026 monetization policy targets "inauthentic", mass-produced content, not AI tools. But robotic, templated scripts read as low-effort, tank retention, and match exactly the pattern that policy flags. Scripts written in your own voice and structure stay safe. If you want every draft to start human, JustShoot's Tone Fingerprint locks your rhythm, language mix, and hooks — plans start at ₹499/month with a 7-day free trial.
