cutaway: When Your AI Coding Assistant Starts Recording Demo Videos

Remember the pain of creating that perfect demo video for your latest side project? The screen recordings that look choppy, the cursor that jumps around like a caffeinated cat, the boring static view that doesn't capture the magic of what you built? Well, cutaway is here to solve that problem in a surprisingly elegant way.

This open-source project (find it on GitHub at github.com/half144/cutaway) tackles a real workflow friction point that many developers and AI coding agents face. When you're building with AI assistants—whether you're vibe coding your startup's MVP or prototyping a new feature at 2 AM—the result exists as code, but sharing it meaningfully often requires additional effort. Cutaway bridges that gap by automatically generating polished demo videos of whatever your coding agent just built.

What makes this particularly clever is the attention to production quality. We're not talking about basic screen recording here. Cutaway adds animated zoom effects that guide the viewer's eye to important interactions, a humanized cursor that moves naturally rather than teleporting across the screen, and motion blur that gives everything a smooth, professional feel. The final output? A local MP4 that looks like it was produced by someone who actually knows what they're doing.

For developers working with AI coding agents like Claude, Copilot, or other vibe coding tools, this opens up interesting possibilities. Imagine your agent not just writing code but also generating marketing-ready demos. You build the feature in the morning, have a polished video by lunch, and can share it with stakeholders or post it publicly without touching video editing software.

The technical implementation handles the recording process locally, which means no cloud dependencies or privacy concerns about your project screenshots being processed elsewhere. Everything stays on your machine until you export that final MP4.

For startups and solo developers especially, this kind of automation is gold. Great demos close deals, attract users, and demonstrate capability. Cutaway doesn't just save time—it potentially elevates how your projects are perceived with minimal additional effort.

As AI-assisted development continues to evolve, we're going to see more tools that extend beyond code generation into the full product lifecycle—including presentation and communication. Cutaway is a small but thoughtful step in that direction.

Have you tried using AI agents to generate your demo content? Or are there other workflow automations you'd love to see for development pipelines? Share your thoughts below—we're curious how you're bridging the gap between "it works" and "let me show you how good this looks."
