EtherPen is an AI script engine for short-drama writers and production studios: it generates full episode-by-episode scripts from an outline, runs five-dimension reviews with pinpoint revisions on existing drafts, and adapts Chinese hit scripts into localized shows for overseas markets. No video generation — we make the script stand up first.
Editor's synopsis · The revenge throughline holds and the heroine's arc is clear; pay points drift off the act climaxes in eps 12 and 24, and hooks run weak in eps 3–7 — tighten per the model fixes…
Video models went through three paradigm shifts in 18 months; script judgment is the asset that survives every cycle. We only build the engine that makes the video worth shooting.
Every AI change ships as a tracked-changes preview a human accepts before it lands; untouched lines stay verbatim.
AI automates what can be measured; senior editors focus on judgment — 200 episodes of screening compressed into 50 that matter.
Write a new one, fix an old one, take a hit global — one shared data contract keeps all three production lines interoperable.
Writers do exactly three things: submit the outline, approve the master sheet, green-light episodes card by card. Behind the scenes, AI builds the character system, act structure, and paywall placement — cutting every pay point on the eve of an act climax.
Bring any asset — an outline, a synopsis, a half-finished draft, or a full script. Get a five-dimension review report in about 9 minutes, fix issues point by point on a Word-style tracked-changes desk, and hand off to the creation line whenever you're ready.
Three confirmations — genre, market, reference show. Then skeleton inheritance plus reskin assembly: emotional anchors and pay-point structure are replicated episode by episode, while characters, worldbuilding, and cultural hooks are rebuilt for the US, Brazil, or Indonesia.
General-purpose LLMs can write dialogue; they can't write paywall structure. Every generation, review, and adaptation in EtherPen is benchmarked against structural assets from real hits.

The market is doubling and video generation is in oversupply — yet what to write, whether it holds, and how to go global still run on manual experience. That is the window for a script-layer engine.
