37Studio is a self-hosted AI video studio and social media desk that turns a short brief into on-brand videos, posts them to nine social platforms, and drafts replies to the messages that come back. Paste a company website and it builds a brand library of logos, photos, fonts, and colours, plus a knowledge base every later video and reply draws on. An editor agent builds each video as an animated composition, checks its own rendered frames, and takes revision requests in plain words. The same workflow yields hook reels, captioned clips, explainers, podcast clips, promo ads, and thumbnails, and any finished video can become a template. A two-hour recording becomes a shelf of short clips: transcription runs locally in about 100 languages at no cost, and YouTube or Drive links import directly. Publishing reaches Facebook Pages, Instagram, YouTube, TikTok, LinkedIn, X, Pinterest, Bluesky, and Mastodon in one action, now or scheduled, each with its own caption. Autopilot goes further: state a content plan in one sentence and a fresh video is made before every slot, waiting for one-click approval. Messenger, Instagram, and WhatsApp messages and social comments land in one inbox, with replies drafted in the customer's language under rules each brand sets. Exact AI spend shows on every project, and an MCP server lets your own AI tools run the studio. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
