What is Mosael
A video studio that folds editing, AI generation, orchestration and publishing into one desktop app.
Mosael is a local-first desktop app that folds the four legs of content creation into a single window:
- Editing — a professional multi-timeline, multi-track editor: ripple editing, speed ramps, transcript-driven cuts, color grading (curves / presets / LUT / scopes), subtitles and filters, one-click export.
- AI generation — a conversational agent operates your project through tools; text-to-image / text-to-video results land in the media library.
- Orchestration — visual workflows chain retrieval, generation, transcription, export and publishing into one graph, triggered manually, on a schedule, or via webhook.
- Publishing — push a finished cut to Douyin / RedNote / WeChat Channels / Bilibili with persistent multi-account logins; the desktop app's embedded browser performs the real upload.
Home to editor in one step — "New project" drops you straight into the editor, no intermediate dialogs:
Architecture at a glance#
- Frontend: Vite + React + TypeScript single-page app, packaged into Electron.
- Backend: FastAPI (Python) + SQLite, the single source of truth for projects, rendering, AI, workflows and publish jobs.
- Executor: a publish executor built into the Electron main process drives embedded browser views for logins and uploads.
- AI agent: hosts an external coding-agent CLI (opencode-style) with Mosael's MCP server as its tool surface; changes go through confirmation cards.
- Data: everything lives in
~/.mosaelon your machine — no cloud dependency, works offline.
Who it's for#
Independent creators and small teams who want to go from editing to multi-platform publishing in one place, automate repetitive work with AI and workflows, and keep their footage off third-party clouds.
The source code is available on GitHub (proprietary license — see About the project).
