Ssemble

Ssemble is a web-based tool that turns long-form YouTube videos into short clips formatted for TikTok, YouTube Shorts, and Instagram Reels, using AI to decide which moments are worth clipping. Its auto-curation feature scans a source video for what it identifies as viral-worthy moments, then applies face tracking to keep a speaker centered when reformatting horizontal footage into vertical video; a separate "sports mode" tracks the ball or action instead of a face for sports content. Clips get automatic captions generated from speech recognition, with translation available in more than 30 languages while keeping the original audio track, plus AI-generated hook titles and calls-to-action meant to improve early retention. Beyond one-off clipping, Ssemble can monitor a connected YouTube channel around the clock and automatically post clips that meet its criteria, with scheduling across platforms handled from within the tool. Pricing is credit-based, starting around $6 per month on annual billing, with higher tiers unlocking more monthly credits and, on the Business and Custom plans, unlimited connected social accounts. It's aimed at content creators, podcasters repurposing long-form audio, and gaming or sports streamers who want a short-form presence without manually editing every clip. Worth noting: some older third-party reviews describe Ssemble as a general-purpose collaborative video editor with manual timeline tools, but its current site focuses specifically on automated YouTube-to-shorts clipping, suggesting its positioning has narrowed over time.
