Sandcastles

Sandcastles helps creators and brands research Instagram, TikTok and YouTube Shorts: it surfaces outlier videos that beat a channel's usual views, explains why they worked and helps you write your own script from them.

You build a feed of channels to track across the three platforms, browse a database of videos flagged as outliers and pull the transcript of any video. Analyses break down the hook, story structure, format and style behind each hit.

Hook templates and storytelling frameworks then help you draft scripts, which can be expanded into longer versions in one click. Projects keep saved ideas organised, and the product also offers an MCP integration and curated collections.
