What if Claude Code updated your screenshots every time you shipped?

Moonjar is a fully agentic studio for product screenshots and videos. Your agent makes them beautiful while you keep shipping.

Works with your existing agent.

Moonjar is an MCP server on your Mac. Whatever agent you already pay for can drive it.

One prompt.
Every asset you need.

Each tab is one real request to Claude Code, and every picture, clip and page Moonjar made from it.

Ask for shots you’d
never make by hand.

Devices side by side, a loupe on one detail, a collage of posts, grain and motion blur: things most screenshot tools can’t do, each one a sentence to your agent.

Can’t this just be a skill?

Things your agent
can’t do alone.

Moonjar is the eyes and memory your agent doesn’t have: every version kept, your taste remembered, five looks to pick from, and everything filed in one place.

Time Machine

Every change is saved. Flip back through every version of an asset and restore any one.

Learns what you like

No more reminding Claude which backgrounds you like for which app. Moonjar remembers.

Variations

See five looks at once instead of one guess. Ask for more like the closest, then use the one you want.

One library

Every screenshot and recording, filed by product in one place. No more digging through Downloads.

Your agent still does the work. Moonjar is where it lands.

What makes Moonjar different.

Not a faster editor. No editor at all.

VERSUS

Screen Studio

CleanShot X

Moonjar is a trulyagent-firstmockup studio.

It’s for people who would rather not make screenshots by hand. Perfect if you ship launches and changelogs, post your product on social, or keep a help center current.

Apps like Screen Studio and CleanShot are great for shots you want to tweak by hand. Moonjar is for people who want their agent to take care of it.

What agent-first actually means →

Fair questions.

Moonjar

Why can’t Claude Code just do this?

It can, it’s just a lot of work. You’d be building device frames, hunting for backgrounds and fixing layouts for every shot. Moonjar gives it all of that, so you only have to ask.

Can’t this just be a skill?

Yes, but it’s really hard. You’d still have to find the backgrounds, frames and assets and tune it until it’s good, and a skill can’t remember what you like, keep every version or show you variations. Moonjar is built for screenshots and does all of it.

Is it free?

During the beta, yes. After that, most likely a free plan with some usage, and a Pro plan for $10–20 a month.

Hi, I’m Chris 👋

I build productivity apps, and every one of them needs screenshots. Help centers, changelogs, App Store shots, posts. Rename one button and forty of them are out of date.

I ship four apps, and my agents already do most of the busywork for all of them. Screenshots were the one chore still eating my time, so I built Moonjar to hand that off too.

It’s the tool I wanted for my own apps, and I hope it gives you some of that time back too.
