37Studio

Overview

What 37Studio does

37Studio is a video studio and a social desk in one app, running in Docker on your own Windows PC, Mac or Linux machine, on your own Claude subscription or API key. Add a company by pasting its website and 37Studio builds a brand library from it — logos, people, photos, fonts, exact colours and a knowledge base about the business. Brief a hook reel, motion-graphics explainer, podcast clip, promo ad, square post or thumbnail, and a Claude Opus 5.5 editor agent writes it as an animated HyperFrames composition from that library, checks its own frames, renders it on the computer and writes a caption for each platform. Gemini and ElevenLabs add generated images, clips, voice and music when a video needs them. A long recording, like a 2-hour class, is transcribed on the computer for free and cut into as many videos as it holds, and any finished video can become a template for the next one. Post to any mix of Facebook Pages, Instagram, YouTube, TikTok, LinkedIn, X, Pinterest, Bluesky and Mastodon accounts now or on a schedule, or let Autopilot make a fresh video before every slot in a content plan and wait for one-click approval. Messenger, Instagram and WhatsApp messages and comments land in one inbox, where Claude drafts each reply from the company's knowledge base in the customer's language, following rules the company writes itself; replies wait for one-click approval or go out on their own. Every project, campaign and company shows exactly what it cost in AI usage, billed by the providers directly and shown in your own currency. Footage, brands and messages stay on the computer, and API keys are encrypted on disk. 37Studio is free and open source under the MIT License: download it, run it, change it, and send issues and pull requests on GitHub.
