Where ideas find their
timeline

Cut footage, find the right moment, generate a shot, let AI lend a hand, and publish the result — without moving your project between a pile of tools. Your media stays on your computer by default.

The Mosael editor: multi-track timeline, dual monitors, media and transcript panels — The editor — multi-track timeline, transcript-driven cuts, color and subtitles, export in one step.

One raw clip, one finished story, no tool-hopping in between

01Editing

The timeline leads

Multiple tracks, ripple edits, speed ramps, color curves and scopes — all there, and none of it buried three menus deep. The transcript and the timeline are the same data: delete a sentence and the picture follows.

02Agent

It acts, but it asks first

The agent drives your project through tools — finding footage, cutting, voicing, exporting. Editing, workflows and boards share one session pool, with a panel that docks or floats. Anything that changes the project surfaces a confirmation card first.

03Workflows

Draw the repetitive part once

Chain retrieval, generation, transcription, assembly and publishing into one graph — run it by hand, on a schedule, or wake it with a webhook. Anything you can do on the canvas the agent can do too; that one is pinned down by tests, not by a claim.

The visual workflow canvas: retrieve → generate → assemble → notify, wired as nodes

Why local-first

Footage isn't uploaded. Projects aren't uploaded. Rendering happens on your machine. You pick the models — bring your own API key, or run Whisper and open weights locally. Which step goes to the cloud is a choice you make, not a default you inherit.

Every bit of state lives in a single ~/.mosael directory, so you can finish a cut with the network unplugged.

Also inside

Knowledge base

Import documents and web pages; local full-text, vector and graph retrieval feeds the agent and your workflows.

Publishing matrix

Douyin · RedNote · WeChat Channels · Bilibili, with persistent multi-account logins and real uploads driven by an embedded browser.

Plugins

Local scripts or existing MCP servers become tools for the agent and workflows, with permissions and credentials granted one by one.
