Introducing Gleiro
A film studio for the agent you already use. It plans the story and shots and proposes edits to the cut, and nothing changes until you approve it.
Words by David Mansaray
- What I was testing
- I wanted to see whether an agent could do the heavy lifting on a film, from storyboard to edit, while the person stays in charge of every change.
- What I found
- It works when the agent proposes and the person decides. Each change is a proposal against a revision that you apply or dismiss, and undo is a new revision, so earlier versions stay in the history.
Gleiro is a film studio for the agent you already use. You start with a brief, your agent drafts the story and shots and works on the edit, and you approve every change in the browser. I started it for my own product, launch and making-of films. It’s a Laravel and Vue app in early development, and access is by request.
The agent proposes, you decide
An agent that edits on its own is hard to trust with a film you’ll put your name to, so in Gleiro it can’t change the cut directly. It proposes a change against the current revision, such as trimming one shot and holding another longer, and nothing moves until you apply or dismiss it. Anything you’ve locked, like a caption, stays put. Undo writes a new revision, so the earlier one stays in the history. Concept frames help you picture a shot on the storyboard, but they never appear in the exported film.
A film you can still open
Every export pins a revision, so you know exactly which cut you’re watching. Alongside film.mp4, at 1920 × 1080 and 30 fps, you get a full-decode audit, a contact sheet, a manifest of sources and the editable project with its original files, so someone else can check the film and carry on editing it. A source whose usage rights the workspace owner hasn’t confirmed blocks the export.
Bring your own agent
Gleiro speaks MCP, so your agent works in the same project you see, through the same commands. Claude Code connects over HTTP with OAuth, Codex with OAuth and PKCE, and any other client through a small local relay with a scoped, revocable token. You approve each grant’s scope and expiry, and an agent can’t grant itself access.
Where it is now
It’s early, and gleiro.com marks its copy as provisional. The opening montage is illustrative, made from concept frames for five example projects. The edit demo uses real footage from a Yondilo development build with illustrative revisions, and the 30-second film in the delivery section was exported from Gleiro.
