From blank page to publish-ready script. ScriptAce's YouTube editor gives you 10 block types, live SEO scoring, auto-generated timestamps, hook strength analysis, and a built-in teleprompter.
Every block type in ScriptAce's YouTube editor — colour-coded, structured, and designed for the full video format lifecycle.
Your first 3–5 seconds. A bold claim, question, or problem statement that stops the scroll and earns the next 8 minutes.
Introduce yourself and the video's value proposition. Quick — viewers clicked for the content, not a long intro. Max 30 seconds.
The core content section. Each chapter appears in the outline navigator and auto-generates a YouTube timestamp. Appears numbered in the outline.
Instructions for the video layer — what footage plays over this segment. Keeps your editor and the camera operator on the same page.
Drive the specific action you want — subscribe, like, comment, click link in bio. One CTA block per action. Multiple CTAs fragment conversion.
Your paid integration — talking points, product USP, promo code, and link. Amber-coded so sponsor reads are unmissable during pre-production review.
A question for the audience or a prepared Q&A segment. Drives comments and keeps watch time high with direct address.
A named chapter marker that appears in the Timestamps tab as a YouTube-ready description line. Format: [0:00] Chapter Title.
Private production note — camera angle, lighting cue, reminder, thumbnail idea. Displayed differently from script content. Exports with full script.
Wrap up, thank viewers, tease the next video, sign off. The outro is where end screens live — write your verbal cue for them here.
Five dedicated tabs give you complete visibility into your script's performance, structure, and optimisation opportunities.
Word count, estimated duration (at your WPM setting), character count, block count, and a progress ring toward your word goal. Readability score updates live.
Enter your target keyword. ScriptAce checks if it's in the title, counts density, and flags missing structural elements. Shows top keywords extracted from your script.
Auto-generated YouTube chapter timestamps from your Hook, Intro, Chapter, Sponsor, CTA, and Outro blocks. Copy all with one click.
Three persistent notepads: Director's Notes (camera/production), Thumbnail Ideas, and Video Description draft. Saves with every keystroke.
Hook Strength Indicator, CTA Placement Hints (ACE). Virality Score and Retention Simulation (PRO).
Choose a template and ScriptAce pre-fills your script with the optimal block structure for each video type.
Personal storytelling with natural hook and lifestyle narrative structure.
Step-by-step educational content with numbered chapters and clear value delivery.
Honest review structure with pros, cons, and verdict. Disclosure-first layout.
Conversational format with Q&A blocks and sponsor integration.
60-second optimised structure — hook-first, value-dense, one CTA only.
Countdown structure with numbered chapter blocks and teased best entry.
Three-act story structure — setup, rising action, climax, resolution.
Organic-first sponsored content that earns trust before introducing the brand.
The recommended workflow for building a complete YouTube video script from scratch in ScriptAce.
ScriptAce doesn't just format your script — it analyses it for viewer psychology, SEO strength, and retention signals.
Total words, estimated duration at your WPM setting, character count, and block count — updated every keystroke. Know if your script is too long before you're on camera.
FreeEnter your target keyword and get a live checklist: title inclusion, density (0.5–2.5% optimal), structural completeness — hook, CTA, chapters. Top keywords extracted automatically.
FreeScriptAce analyses your Intro Hook block — word count, use of questions/exclamations, length — and scores it 0–100. Flags weak hooks before you go live.
ACEChecks whether your CTA block is present and positioned correctly. Flags missing CTAs and suggests adding a Value Exchange phrase to improve conversion.
ACEA composite 0–100 score based on viewer psychology patterns — hook strength, content depth, pacing signals. The single number that tells you if a script has hit potential.
PROModels your estimated average view duration based on block structure, pacing, and script length. Shows a predicted retention curve so you can fix drop-off points before filming.
PROWrite your Intro Hook block before anything else. 70% of viewers decide in the first 5 seconds. Your hook should open a loop that can only be closed by watching.
Go to the Stats tab and set your speaking pace before estimating duration. If you naturally speak fast (150+ WPM), your duration estimates will be wildly off at the 130 default.
Each Chapter block should cover exactly one concept. If you're writing more than 200 words per chapter, split it. More chapters = more timestamps = better YouTube SEO.
Every time you make a strong claim in a Chapter block, immediately add a B-Roll Note describing the visual proof. "Here's the data" needs to show data. "Here's me using the product" needs footage.
Mid-roll sponsor placement at 25–40% watch time outperforms both pre-roll and post-roll by 3×. Add your Sponsor block after Chapter 2 — not at the beginning and not at the end.
Add a soft CTA after your best chapter ("drop a comment if you agree") and a hard CTA before the outro. The soft one builds engagement mid-video; the hard one converts at the end.
In your Outro block, always end with a 5-second tease of the next video. "Next week I'm covering X — you'll want to see that." This is your end screen's verbal cue and it spikes click-through on suggested videos.
Switch to the Timestamps tab and click Copy All before uploading. Paste into the YouTube description field. Chapter markers increase search surface and tell YouTube's algorithm you have structured content.
Click Export PDF in the topbar. ScriptAce generates a polished PDF using jsPDF — no server, instant download.
All blocks labelled and colour-coded. Formatted for print or on-screen reading during filming.
Click Prompter in the topbar. Scrolls your script full-screen with variable speed. Excludes B-Roll and Director's Note blocks from the scroll.
