Welcome to Jumble, your go-to source for the latest news in artificial intelligence. Big Tech just handed us two brand-new agents—one that builds mini-apps and one that runs the web for you. Let’s dive in ⬇️
In today’s newsletter:
💡 Google’s Opal converts plain-English ideas into working code
🛟 Microsoft Edge adds a free Copilot browsing mode
🧪 Anthropic rolls out self-auditing safety agents
🦉 Study shows AI models can secretly nudge each other
🛠️ Challenge: Build your first mini-app with Opal

Google quietly unveiled Opal, a Gemini-powered coding agent that lives right in your browser. Announced on the Google Developers blog, Opal promises to turn a natural-language prompt—“Build me a to-do tracker that pings Slack every Friday”—into a runnable web app in minutes.
Type an idea in the Opal sandbox, and the agent:
Generates a design brief.
Writes front-end code with React Lite or vanilla HTML (you choose).
Stitches back-end functions via Firebase or your own API keys.
Spins up a live preview and editable repo.
Developers can then tweak the output, models used, and so much more.
🚨 NEW LABS EXPERIMENT 🚨
Introducing Opal, our new way to help you build and share AI mini-apps by linking together prompts, models, and tools— all while using simple, natural language (without a single line of code 🤯)
Now available in US-only public beta! Learn more ⬇️

The tool provides a visual workflow editor, allowing you to easily track and edit each step of your app's creation, connecting prompts, AI models, and other tools. You can even start with pre-built templates, like an app that turns a photo into a claymation video or generates a quiz from a YouTube video.
There are plenty of vibe coding apps on the market, but what sets Opal apart is that it’s free, backed by Google, and only going to get better from here.
Free tier: anyone with a Google account gets ten builds per day—no credit card, no waitlist.
Rapid prototyping: side hustlers can validate an idea over lunch instead of a weekend.
Education: the agent annotates every function, turning the codebase into a live tutorial.
Analysts note Opal could pull hobby coders away from Replit and GitHub Copilot, especially with Google’s distribution muscle behind it.
A roadmap teases voice prompting, team collaboration, and Android APK export. Google also hints that Opal could surface inside Workspace, letting you conjure custom internal tools from a Gmail thread. For now, the vibe-coding future is one URL away - https://opal.withgoogle.com/ - and it’s free. Your move, GitHub.
Microsoft has integrated a new, free AI agent directly into its Edge browser, transforming it into an "AI browser" with the launch of Copilot mode. This move aims to enhance your Browse experience by providing AI-powered assistance for a variety of tasks, directly within your web activities.
Copilot mode in Microsoft Edge goes beyond traditional search engines by offering real-time AI assistance as you browse. Whether you’re researching a topic, drafting an email, or summarizing a lengthy article, Copilot can jump in to help. It’s designed to understand the context of your browse, providing relevant information, generating content, and even performing actions on your behalf without requiring you to switch tabs or applications.
Today we’re introducing Copilot Mode in Edge, our first step in reinventing the browser for the AI age.
My favorite feature is multi-tab RAG. You can use Copilot to analyze your open tabs, like I do here with papers our team has published in @Nature journals over the last year.

From accelerating everyday tasks to staying focused, there’s many use cases and features that Copilot unlocks:
Page Summaries: click Copilot, and it outlines headings, FAQs, and actionable links.
Form Filler: with permission, it scrapes common fields (name, address) from your Microsoft account.
Multi-Step Workflows: ask “compare three Bluetooth speakers under $200,” and it opens tabs, scores specs, and returns a ranked list.
Unlike Bing Chat, Copilot Mode runs locally for lightweight jobs, then calls cloud models (GPT-4o mini) for heavy lifting. Privacy toggles let you disable cloud calls per site.
Today is a big step towards an AI browser: Copilot Mode in Edge, built for how your brain actually works. Voice control, no digital clutter, and multi-tab context, all grounded in privacy and security. Try it at aka.ms/copilot-mode + feel the difference of 🧵

It’s free (for a limited time) for all Edge users on Windows, macOS, and Linux—no Microsoft 365 subscription required. Enterprise admins can disable or audit prompts via Group Policy.
Some are calling it “the closest thing yet to an AI browser for the masses,” while others complain the agent sometimes mis-labels ads as “main content.” Microsoft says fixes roll out weekly.
If Copilot Mode sticks, Chrome’s blank omnibox suddenly looks 2010. Expect rapid copycat moves—or deeper integrations with Google’s own Gemini extensions.
Ever dreamed of building your own app but don't know how to code? Now you can! Google Opal is a new AI tool that turns your ideas into real apps, right in your web browser.
Challenge: Turn your ideas into apps with Google Opal.

1. 💭 Dream It Up: Think of a simple app you’d love to have. For example:
"A daily reading tracker that reminds me at 9 PM to hit my chapter goal."
"A quick tool to list my favorite local coffee shops."
"An app that helps me manage my weekly grocery list and checks off items."
2. 🗣️ Tell Opal Your Idea: Visit https://opal.withgoogle.com/ and type in your app idea. Opal, powered by Google's Gemini AI, will begin building it for you. You can pick a "Starter Pack" like a "Dashboard" for tracking or a "Form-Collector" for gathering info.
3. 🧑🔬 Tweak & Test: In the live editor, you can easily change colors, text, and add connections like sending emails (no coding required). You can even test your app to see it in action.
4. 📲 Share Your App: Hit "Publish" and choose "Firebase Hosting" to get a live, secure link to your new app in about 90 seconds.
