What's the most important part to fix?

The first 30 seconds. The opening hook and time-to-value carry the most weight because that's where most drop-off happens.

What counts as filler?

Throat-clearing and padding like "hey guys, welcome back, before we begin, without further ado, basically, you know."

What's a good retention score here?

80+ is tight, 55–79 has slow spots to trim, and below 55 risks early drop-off. Treat it as a guide.

Can I check just my intro?

Yes — pasting only the first 30 seconds is a great use, since the opening matters most.

How is spoken time estimated?

From word count at roughly 150 words per minute, a typical speaking pace.

Does sentence length really matter?

Yes — long, uniform sentences feel monotonous out loud. Varied, shorter lines hold attention better.

No — everything is analyzed locally in your browser and nothing is saved or sent.

Will a high score guarantee retention?

No tool can promise that — delivery, editing and topic matter too. This fixes the script-level basics.

YouTube Script Retention Checker

Paste your script — or just the first 30 seconds — and find the patterns that make viewers click away early. This checker scores your hook speed, filler and throat-clearing, time-to-value, sentence pacing and direct engagement, with a specific fix for each. It reads the words, not the video, so use it to tighten your script before you film.

Your script or intro

This reads your script text for the patterns that lose early viewers — slow hooks, filler, long intros, monotonous pacing. It can't watch your actual video, so it judges the words, not the edit. Strongest signal: fix the first 30 seconds.

Quick answers

Straight to the point

Why do viewers leave my YouTube videos early?

Most early drop-off comes from a slow start: filler like "hey guys, welcome back, before we begin," a long intro before the payoff, or a weak first line. The opening 30 seconds decide whether people stay. This tool scans your script for those exact patterns and shows you what to cut or tighten.

How do I improve audience retention on YouTube?

Hook viewers in the first five seconds, reach the value fast, cut throat-clearing, and vary your pacing with short, punchy sentences. Speak directly to the viewer and ask questions. Paste your script here and the checker scores each of these and tells you precisely where your opening drags.

Why this tool

What makes the Script Retention Checker useful

Audience retention is one of YouTube's strongest ranking signals, and the biggest, most fixable losses happen at the start. Spotting a slow hook or a wall of filler in your script — before you record — is far cheaper than re-filming.

What is the Script Retention Checker?

The Script Retention Checker analyzes your video script for the textual patterns that correlate with early viewer drop-off — slow hooks, filler, long intros and monotonous pacing — and returns a score with fixes.

Who should use it?

Creators scripting before they film, anyone whose retention graph drops sharply in the first 30 seconds, and those who want an objective second read on their opening.

Common use cases

Tightening a script before filming
Diagnosing a sharp early retention drop
Cutting filler from your intro
Comparing two opening hooks

Pro tips

• Put your strongest claim or question in the very first line.
• Cut every phrase that doesn't move the video forward.
• Read it aloud — if you're bored saying it, they're bored hearing it.

Mistakes to avoid

• Opening with "hey guys, welcome back" instead of the hook.
• Spending 30+ seconds on intro before any payoff.
• Long, dense sentences that feel monotonous when spoken.
• Never addressing the viewer directly or asking questions.
