AI for Screenwriting and Scripts

Screenwriting may be the only major writing category where forensic measurement, not survey self-reporting, gives the cleanest read. Originality.ai analyzed transcripts of approximately 3,800 US TV episodes that aired from 2020 to 2023 and found just 1.9% average probability of AI-generated content — and most of that is likely false positives in the detector. Meanwhile, the 2023 Writers Guild of America strike lasted 148 days largely because of AI fears, ending with a contract that explicitly bans studios from using AI to write or rewrite scripts. This page tracks both sides: the contractual restrictions in place and the measured low actual use.

CHART 1 · THE FORENSIC BASELINE

Detected AI content in TV scripts by genre, 2020–2023

Loading chart...
Source: Originality.ai forensic detection study. Approximately 3,800 US TV episode transcripts analyzed across genres including drama, comedy, soap opera, and reality. Overall average: 1.9% probability of AI content. Soap operas showed the steepest year-over-year rise: 1.3% (2020) → 4.5% (2023). Detection methods have known false-positive rates of approximately 1–2%, so the soap opera trend is suggestive but not conclusive.
CHART 2 · THE STRIKE

2023 WGA strike timeline

Loading chart...
Source: Writers Guild of America public records; NBC News, NPR, Brookings coverage. Days: 148-day strike (May 2 – September 27, 2023). Member vote on tentative agreement: 99% approval among voting members. Estimated economic impact on California economy: $5B+ across all parties affected.
CHART 3 · WHAT THE CONTRACT BANS

WGA 2023 AI protections

CHART 4 · THE COPYRIGHT WRINKLE

Why studios can't safely use AI-generated scripts (even if they wanted to)

Loading chart...
Source: US Copyright Office guidance (March 2023, updated 2024): AI-generated works without sufficient human authorship cannot be copyrighted. AI-assisted works require disclosure and human authorship. EditorsPro 2025 industry analysis. Together, these create economic disincentives: a script that cannot be copyrighted is potentially public domain on release, undermining studio investment.

About this data

The AI Behavior Index is the research arm of OneChat AI. This page focuses on AI applied to screenplay and script writing for film, television, and streaming. It draws on Originality.ai's forensic detection study (the largest publicly available analysis of actual scripts) and the WGA 2023 contractual record (the most consequential labor agreement on AI in any creative industry).

Two methodological notes worth flagging. First, Originality.ai's AI detection has known accuracy limits — typically 1–2% false positive rate — meaning the 1.9% average for Hollywood scripts is at or near the detector's noise floor. The conclusion isn't "no AI" but "no measurable AI." Second, the data window ends in 2023, before the most recent acceleration in AI capability. Originality.ai has indicated plans to continue the study; updated forensic data is not yet publicly available. The WGA contract itself runs through May 2026 and will be renegotiated. Data is refreshed when major studies publish. If you have a study to suggest or notice an error, contact us at research@aibehaviorindex.org.
