What is the best AI for writing video scripts?

For short-form scripts, FlowShorts generates retention-optimized scripts and turns them into complete videos. For long-form YouTube scripts, ChatGPT and Claude both produce quality output — Claude excels at narrative depth while ChatGPT is more versatile.

Can AI write YouTube scripts that get views?

AI-generated scripts can perform well when they follow proven retention patterns — strong hooks, curiosity loops, and clear value delivery. FlowShorts builds these patterns into its script generation automatically. For manual scripts, prompt engineering is key.

How long should a video script be?

For YouTube Shorts and TikTok, aim for 100-180 words (30-60 seconds). For standard YouTube videos, 1,500-2,500 words (10-15 minutes) hits the sweet spot for ad revenue and audience retention.
