A 10-minute video needs roughly 1,400 words of script, because most people speak at a comfortable on-camera pace of about 140 words per minute. That math holds for a fairly conversational delivery; if you talk faster or pause a lot for visuals, your actual runtime will drift, so treat the word count as a target rather than a stopwatch. This tool builds its lengths around that 140-words-per-minute pace: the 5-minute preset lands near 700 words, 10 minutes near 1,400, 15 minutes near 2,100, and 20 minutes near 2,800. It also splits the body into a sensible number of timed sections — about four for a 10-minute video — so the pacing is baked into the outline. Pick a duration and the writer sizes the whole script for you, no manual counting required.

A good YouTube hook earns the first 30 seconds by promising something specific and creating a reason to keep watching — a bold claim, a surprising result, a question the viewer wants answered, or a quick preview of the payoff. It should land before any long intro or channel branding, because the opening seconds are where most viewers decide whether to stay. The tone matters too: a tutorial hook reassures, while an entertainment hook hypes. This tool writes a dedicated hook segment for the 0:00–0:30 slot in the voice of the style you choose, and pairs it with a b-roll note for an energetic cold open. The subscribe ask is deliberately placed afterward, in the 0:30–1:30 intro, so the prompt lands once you've shown value. Enter your topic and style to get a structured hook you can refine to fit your own angle.

The most effective spot for a subscribe ask is after your hook but before the main value — once the viewer has a reason to care, but before they've gotten everything they came for. Front-loading it over the very first frame tends to feel pushy, while saving it entirely for the end means most viewers never hear it. A short, natural ask woven into the intro converts better than a hard sell. This tool follows that structure: it writes the subscribe CTA into the 0:30–1:30 intro segment, right after the hook, so it lands at the moment of peak goodwill. The outro then carries your own custom call-to-action — like "grab the free guide in the description" — plus end-screen prompts for two related videos. Add your CTA text and the writer places both asks for you in the right slots.

B-roll is the supplementary footage you cut to while your main narration continues — screen recordings, demos, stock clips, cutaways, or scenery — and it keeps a talking-head video visually alive instead of static. Scripting b-roll cues in advance matters because it tells you what to film or gather before the edit, so you're not scrambling for visuals later or staring at a shot list you forgot to plan. This tool embeds bracketed b-roll cues throughout the script: an energetic note for the cold-open hook, and a cue inside each main section marking where supporting footage should go. Those brackets double as a checklist — fill each one with your own clip and the video gains pace. Because the placeholders mark exactly where your footage belongs, you can plan the shoot and the edit straight from the script. Generate a script to see the cues laid out section by section.

Usually no — a script reads best as scaffolding rather than a rigid teleprompter feed. Reading every word verbatim often sounds stiff, and viewers can tell when delivery is robotic. The stronger approach is to use the script for structure and pacing, then deliver each beat in your own voice, keeping the wording loose where it helps you sound natural. This tool is built for exactly that: it produces a production document with a hook, intro, timed sections, and outro, but the main sections use bracketed talking-point prompts — a key idea, a real-world example, and a "pro insight" — that you fill with your own material. Swap in placeholders like [Your Name] and [your niche], expand the prompts, and you have a shoot-ready outline that still sounds like you. The output is editable markdown, so you can tighten any line before filming, then copy or download it.
