What should Spark create
for your stream?

Your game deserves a matching stream

Create overlays inspired by whatever you’re playing. Describe the world you want around your gameplay, and your stream steps into it.

Make my Minecraft stream feel cozy at night, and let chat take my hearts.

Your audience is part of the stream

Create new ways for your chat to be part of the show. Games, polls, challenges, or something nobody has tried yet: if you can describe it, your community can play it.

Make every alert a main event

Create alerts for every follow, sub, raid, and cheer, in any look you can dream up. Every moment of support gets the celebration it deserves.

Voice reactive overlays

Create overlays that respond to your voice in any way you can imagine. From catchphrases to inside jokes, if you say it, your stream can react.

Live captions with your personality

Create speech-to-text overlays in any style you want. Help every viewer follow along, even with the sound off.

Make your stream unmistakably yours

You built a brand your community loves. Bring your logo and describe your vibe, and everything you create carries it, so viewers know it’s you at a glance.

Here's my logo. Make a set of scenes with my visual identity.

Frequently Asked Questions

What is Meld Spark?

Spark is a chat-based creative tool built directly into Meld Studio. You describe what you want in plain language and Spark builds it for you through a series of prompts.

What can Spark build?

Spark can build anything that runs as a browser-based overlay in your scene. Things like animated alerts, starting soon screens, overlays, and more. It can also apply effects to existing layers, move layers between scenes, and edit anything it creates.

Does Spark use AI?

Spark uses Google Gemini to understand your requests and write code. Importantly, Spark's output is always code (HTML, CSS, and JavaScript), not generated images, audio or video. Think of it like having your own personal developer inside Meld Studio. It is not an image generator.

Can I use Meld Studio without Spark?

Yes! Spark is completely optional. Choosing not to use it has no impact on your normal Meld Studio experience.

Can Spark access my files, microphone, or camera?

No. Spark cannot read your filesystem, access your microphone, camera feed, or system audio. The only files it ever sees are ones you deliberately drag into the Spark chat yourself.

Can Spark replicate or steal a commissioned artist's work?

No. Because Spark writes code rather than generating images, it cannot reproduce, extract, or replicate artwork.

What about deepfakes or non-consensual content?

Spark is not a media generation tool and cannot produce deepfakes, fake images, or any non-consensual content. This is precisely why we built Spark to be purposeful and contained.

What will you create for your next stream?

Start with one idea: a signature alert, a chat game, or a whole new look. Tell Meld Spark what you have in mind.
