What Sandcastles does
Sandcastles is an AI-powered SaaS platform for researching short-form video ideas and turning that research into scripts. The site describes it as a tool for finding top channels in a niche, identifying viral outliers, and remixing what makes them work into new videos.
The product centers on a four-step workflow: customize a feed, find outlier videos, understand why they went viral, and write new scripts from those insights. It supports research across Instagram, TikTok, and YouTube Shorts, and it is presented as a way to reduce manual idea research and scripting work.
Features
Find outlier videos at scale
Browse a database with millions of validated outliers and focus on videos that stand out in performance within their category.
Generate hooks quickly
Generate hook ideas from templates informed by millions of views, which helps speed up early-stage scripting.
Monitor channels across platforms
Track channels across Instagram, TikTok, and YouTube Shorts in one place to review performance patterns over time.
Pull video transcripts instantly
Download transcripts from videos so you can reference the wording and structure of strong examples without manual copying.
Write scripts from research
Use AI-assisted workflows to turn research into scripts, including story themes and data-backed storytelling frameworks.
Common use cases
