Real web research before a word is written, then a long-form script with hooks, pacing and structure built in, in the voice you saved for the channel — and within a couple of per cent of your target word count.
Measured across the scripts written between 1 August and 20 September 2026. Accuracy climbs with length rather than falling: under about 2,000 words the hit rate drops to roughly two in three, which is the honest shape of a tool built for long-form.
A script that comes back a third short is a video you cannot publish, and length is where most AI writers quietly give up. The figures above are the measured result, and the honest shape of a tool built for long-form.
Most AI scripts are surface-level because the model writes from memory. Autotube runs web research on the topic first and writes from the sources, so a two-hour history episode has the dates, names and specifics that keep a viewer listening.
Research can also run per section, so a long script gets a fresh brief for each part rather than one pass stretched over three hours of narration.
Scripts are written section by section against an outline, with a rolling summary carried forward so the ending still knows what the opening promised.
Creator writes up to 30,000 words; Pro and Own Keys go to 45,000, which narrates to roughly three hours. There is no tier where long-form is the thing you have to upgrade for — the ceiling moves, the capability does not.
The outline is generated before the draft and is yours to change: reorder sections, rewrite a section's brief, add one, cut one. The script is then written to the outline you approved.
Dual-model mode writes the opening sections on the stronger model and the rest on a cheaper one, with the split under your control. The opening decides whether anyone stays; the middle of a 40,000-word script does not need the same spend per word.
You can also run the outline on a different model from the draft. Every combination shows its exact credit cost before it runs.
A script preset holds the channel's tone, structure, word count and standing rules, so the tenth video sounds like the first. Each script then takes its own instructions — an angle, a fact to include, a thing to avoid — applied to that run alone.
Every plan includes the full pipeline. The app shows the exact credit cost before you run anything.
