YouTube scripts are spoken-word writing, and AI markers ruin spoken words faster than anything else. ChatGPT, Claude, Gemini, and Copilot all draft for the page, not the mic. Viewers hear a robotic hook in three seconds. They hear stiff written vocabulary as soon as your voiceover starts. Retention drops in the first 30 seconds, the algorithm reads that as a weak video, and reach gets pulled on the next upload. TextSight rewrites the script before you record across long-form videos, Shorts, intros, outros, sponsor reads, and video descriptions. Honest framing: spoken voice plus creator authenticity, sitting on the safer side of the YouTube Inauthentic Content policy.
A blog reader can skim past a clunky paragraph. A YouTube viewer cannot. They hear every word in the order you spoke it, with no skim affordance, and the written-vs-spoken cadence mismatch is exposed on the first sentence.
YouTube does not flag AI scripts directly. The 2024 Inauthentic Content policy targets mass-produced or repetitious channels rather than the existence of a draft from ChatGPT or Gemini. What the algorithm measures is click-through rate, average view duration, audience retention, and session watch time. AI scripts hurt all four. The typical retention drop on AI-written 10-minute videos is 18 to 22 percent in the first 30 seconds, against 35 to 42 percent on scripts that went through a real human edit.
Every major LLM defaults to the same openers. Have you ever wondered. In today's video. Today on the show. Welcome back to the channel. Make sure to subscribe at the start. Viewers have heard these on every AI-narrated channel for two years and swipe away on reflex. Long-form videos over 10 minutes feel this most because retention compounds: a weak opening means fewer viewers reach the second beat, then the third.
AI prose averages around 18 to 24 word sentences with uniform paragraph rhythm. Spoken English moves in 8 to 14 word bursts with deliberate variation. Long sentences need breath markers and clause breaks. AI scripts have neither, so the voiceover rushes through paragraphs that were never built for the lungs. The audience hears the rush, even if they cannot name the cause.
Faceless channels run AI scripts through AI voice tools by default. The viewer hears two layers of artificiality stacked. The Inauthentic Content policy is enforced hardest against this combination because the channel pattern matches the mass-produced profile. Rewriting the script removes the first layer and gives the voice model speech-shaped sentences to work with, which softens the second layer too.
Invisible on the page, obvious in the audio. Read your script aloud once and listen for any of these before you record.
Have you ever wondered. In today's video. Today on the show. Welcome back to the channel. What if I told you. Picture this. Five or six openers carry 80 percent of AI-drafted YouTube scripts across ChatGPT, Claude, Gemini, and Copilot. Viewers tune them out in three seconds. The fix is to open with a specific number, a confession, or a contrarian claim. Two sentences max, no setup.
Utilise, leverage, navigate, robust, comprehensive, holistic, paradigm, in today's modern world. Words nobody says out loud, dropped into sentences a voiceover artist now has to pronounce. The audio reveals the script source instantly. Replace each with the spoken-English equivalent: use, get, work through, strong, full, whole. Speak the sentence aloud before approving it.
AI prose lacks comma-pauses, em-dash clause breaks, and full-stop punches. The script reads in four lines, but the voiceover takes 18 seconds without a breath, and the delivery sounds rushed. Break long sentences into two or three short ones. Aim for 8 to 14 words per sentence on most lines, with one longer sentence every fourth or fifth for shape.
AI defaults to do not, cannot, it is, you are. Spoken English uses don't, can't, it's, you're around 95 percent of the time. Real creators also drop in rhetorical questions and direct address. Right? You know what I mean? AI scripts skip every conversational interrupt and the voiceover ends up sounding like a Wikipedia read-aloud. Ctrl-F the full forms, replace, and insert one rhetorical question per minute.
Creator voice lives in the asides. The throwaway joke. The side note. The "full disclosure, this used to be my favourite" aside. AI strips all of it because it cannot fake first-hand experience. The script ends up sounding like an explainer with no human in it. Add one personal aside per minute. A specific opinion or small story is enough.
AI outros restate every point, thank the viewer, then add Make sure to subscribe in the same robotic cadence. Viewers have already left by the recap, and the algorithm caught the drop. End on a single sharp line, a question for the comments, or a teaser for the next video. The subscribe ask sits at the 30 percent mark of runtime, not the end.
The AI rewriter workflow is the same. The priority of fixes shifts with the format. Long-form videos live or die on the hook, Shorts on the first word, sponsor reads on approved-copy preservation.
The standard target. First 30 seconds carries the whole video, so the hook rewrite is the highest-leverage edit. Run the script through Balanced for the bulk rewrite, then do a hand pass on the opener. Long-form scripts run 7,000 to 10,000 characters for a 10-minute video, well inside the Pro tier's 50,000 daily allowance. About five long-form scripts a day on Pro.
A 60-second Shorts script has no room for a slow hook. AI hooks burn the first four seconds on setup, which is 7 percent of runtime. Cut to the payoff in word one. Use Maximum aggressively here because the rewrite needs to compress as well as rewrite. A Shorts script runs 800 to 1,200 characters, well under the free tier's 5,000-per-day authenticity cap. Four to six Shorts per day on free.
Channel-brand wording, often approved or repeated across episodes. Use Light here so the rewrite preserves your established opener and closer. The fix is usually contraction insertion and one breath marker, not a full rewrite. If your channel intro is "In today's video" boilerplate, this is the place to retire it once and forever.
The most sensitive block in any script. The sponsor approved specific copy, and rewriting their claims is a breach of contract. Use Light mode only. The AI rewriter is allowed to fix cadence, contractions, and breath markers. It is not allowed to change product names, feature claims, or the call-to-action wording. Run the sponsor read separately from the rest of the script and never in Maximum.
Not spoken, but heavily AI-flavoured in most channels. Descriptions get scanned by viewers for relevance and by the algorithm for context. AI-written descriptions read like product copy: comprehensive, leverage, robust. Run them through Balanced and then trim by half. A YouTube description is shorter than the AI wants to make it.
Free fits a daily Shorts schedule or one long-form attempt. Pro fits a creator running multiple long-form videos a week. Business fits agencies managing client channels. Full details on the pricing page.

YouTube scripts mix several text types in one document. The mode map below picks the right setting for each block so the rewrite never destroys approved copy or weakens your brand intro.
The right starting point for the body of a 10 to 25 minute video. Restores spoken cadence, breath markers, contractions, and varied sentence rhythm without rewriting your beats. Safe on the bulk of any script. Run the body of every long-form upload through Balanced first, then do the hook rewrite by hand.
Smallest edits, preserves wording. The right setting for sponsor reads where the brand approved specific claims, and for channel-brand intros and outros that need to stay recognisable across episodes. Fixes cadence and contractions, leaves product names, claims, and approved phrasing alone.
Deepest rewrite that breaks sentence shapes and compresses prose. Right for daily Shorts where the script needs to compress as well as rewrite, and for faceless-channel long-form where the script has to clear a higher authenticity bar to survive the AI-narration-on-AI-script double trap. Always do a 5-minute manual pass after Maximum to revert any written-only words that crept back.
Twenty minutes per 10-minute script from raw AI draft to record-ready. The AI rewriter handles cadence and the formulaic openers. You handle hook, voice, and asides. The read-aloud pass is non-negotiable.
Let ChatGPT, Claude, Gemini, or Copilot produce the rough script. Do not fix AI prose in the draft stage. Keep the structure, the beats, the order of points. Throw the wording away. The AI rewriter is the right place to fix wording, not the prompt.
Copy the script out and separate the first 30 seconds (hook), the body, any sponsor reads, and the outro. Each block goes through a different mode. Mixing them in one paste loses control of the rewrite depth and risks Maximum wrecking your approved sponsor copy.
Paste the body into app.textsight.ai and run Balanced. Watch for written-only vocabulary, missing contractions, and uniform paragraph rhythm. Accept the rewrite suggestions on the highlighted spans. Paste the cleaned block back into the script.
Delete every word before the first concrete fact. Open on a specific number, claim, or confession. Promise the payoff in the next 10 seconds. Read the hook aloud and time it: under 15 seconds or it gets cut. The hook is the only part of the script worth rewriting three times.
Read the full script out loud at delivery speed. Mark every word you stumbled on and every sentence that did not sound like you. Replace with words you actually say. Add one personal aside per minute. If a sponsor read still sounds AI, run it through Light again. Then press record.
