Muse is out today. An agent like this is a different kind of system to design. It reads your mail, spends your money, runs your code. Getting that right took real care, and our technical post walks through exactly how. We designed security in.

🚨 Our #1 most requested feature is here: You can now export designs from any Stitch agent directly to Figma as editable layers. Vibe Design is perfect for exploring many ideas in minutes. But sometimes, you need that final layer of polish. Now you can move seamlessly between vibe design and polish.

Gemini 3 Flash ⚡️ is coming to Stitch! Faster iteration helps you design better products. You can now explore more ideas at faster speeds with amazing quality. If you need more reasoning power, use Pro. We find the best results come from trying multiple options quickly, branching out before converging to the perfect design. Check out the speed difference with Pro

Shipmas Day 2: Bonus Drop. 🚢🎁 We taught Nano Banana Pro to see like a user. 👀 Introducing Predictive Heatmaps. Now you can run an instant attention audit on any screen you design. Ensure your users are focused exactly where you want them to be—before you write a line of code and without waiting for data. Live now in the Generate menu.

This has been a major game changer for the Stitch team
Introducing Scheduled Tasks. Continuous Integration meets Continuous AI. Set the frequency: nightly package releases, weekly dependency updates, or monthly backlog sweeps. Jules not only can publish the release but can fix any errors while doing it, all in background while you focus on what matters (or get some sleep). Available to all users today: jules.google.com

Welcome to Shipmas Day 1. 🚢🎁 We have a new ship every day this week and a big launch Wednesday! First up: We’re unlocking the Redesign Agent by taking the image output and letting you generate code. Powered by Nano Banana Pro, our agent has been taking a screenshot of your app and visually reimagining it. We love the creativity, but disliked how you didn’t have access to the code. Now we’ve added Code Generation. Now you can take those Nano Banana Pro redesigns and convert them into working HTML. Screenshot ➡️ Redesign ➡️ Code ➡️ AI Studio or Your Coding Agent.

I genuinely can't even begin to explain how good Nano Banana Pro is. — Infographics: Comic strips, menus, marketing, wedding invites, even fake receipts?!. This one-shots every thing I'd need Canva for. — Logo Design: It one-shotted every single logo design I threw it. New logos. Resurrecting old logos. I almost cried seeing how good it made my school logo — Photoshop-like Editing: It's just.. perfect. Make me taller. Make me fitter. Move my hand. Remove background. Change my clothes It nails everything. It is by far the best image editing model I've ever seen.

Today: Stitch gets 1-Click Export to AI Studio. 📅 It's the perfect storm. You can now easily build your beautiful designs with the most capable model available. It was our most requested feature for a reason. Go build something real, fast.

Jules can now work with environment variables. Provide API keys, tokens, or other configurations to let Jules run more complex builds, tests, and interact with external services. Configure them once at the repo level and enable them when starting a task

I wanted to use designs from Stitch as context for Jules as it built out a nanny calendar app for me. Here's what I did. Demo video at the end! First, I asked Stitch to make the designs for me. 🧵

don't sleep on @julesagent. point it towards a github repo, give it a task, come back when it's finished it works server-side so you can use it on your mobile (i.e. give it tasks while you're outside touching grass)
