SimilarClip is an AI video engine for YouTube channels that run themselves. Pick a niche and connect a YouTube channel, and it researches the topic, writes the script, breaks it into scenes and generates fresh visuals and narration for each one. You choose from 11 visual styles and 35 natural voices, set a publishing cadence, and new episodes go out automatically - no camera, no editing and no source footage needed. Every script is written fresh and every visual and voiceover is generated new. SimilarClip also provides an MCP server and a REST API, so agents can generate and publish videos with an API key. It is a paid subscription (from $39/month) with monthly AI credits; extra credit packs never expire.
