PLUS: How to remove unwanted digital footprint with Claude
4 new AI tools worth trying today
TOGETHER WITH RUBRIK
Claude is running in your enterprise.
It’s scheduling, drafting, analyzing, and making calls—and in most organizations, nobody has a clear answer to a very simple question: what exactly is it doing?
That’s not a Claude problem. That’s a governance problem. And it’s exactly what turns a well-intentioned AI agent into something that accesses what it shouldn’t, skips the steps it finds inconvenient, and causes damage faster than anyone can react.
Rubrik is Customer Zero for this problem.
They are deploying Claude. Rubrik is the first organization to put Rubrik Agent Cloud to work governing a live Claude implementation, and on June 30, they are opening that experience up in a hands-on lab.
This isn’t a webinar. You will:
Watch a Claude deployment go off-script live,
see Rubrik Agent Cloud catch it in real time,
and then fix it yourself in a proctored lab environment.

AI AGENTS
Microsoft’s CEO Satya Nadella announced that Microsoft is bringing Skills to Copilot for Excel, giving teams a new way to save AI workflows and share them across every workbook in their organization.
Skills let teams build a prompt or analysis workflow once inside Excel, save it as a named skill, and share it so anyone in the organization can run the same logic across any workbook without rebuilding it from scratch.
Microsoft ships a sample library of finance skills out of the box, covering tasks like building buyer lists, running performance calculations, cleaning data, and generating competitor analysis, giving finance teams a starting point without custom setup.
Each skill appears in the Copilot side panel as a named command, so team members can apply expert-level workflows with a single click even if they did not build them.
The update extends the Skills system that already exists across Copilot into Excel specifically, making the spreadsheet environment a place where institutional AI knowledge can live and be reused.
Excel is where a significant amount of real business analysis actually happens, but most AI assistance in spreadsheets has been one-off prompting. Skills change that by letting organizations capture their best workflows and make them reusable. A finance team that builds a clean model once no longer has to rebuild it every time a new analyst joins.
AI TOOLS
Google launched Study Notebooks inside the Gemini app, an interactive learning space designed to turn curiosity into understanding, available for free in every language globally.
Study Notebooks let users create a dedicated space for any subject, from organic chemistry to personal finance, where Gemini builds personalized explanations, quizzes, and structured learning paths based on what they want to understand.
The feature is free and available globally in every language inside the Gemini app, with no subscription required, making it one of the broadest free AI learning tools available right now.
Notebooks sit in the Gemini sidebar alongside chats and Daily Brief, so users can jump directly into a learning session without starting a general conversation first.
The design targets students preparing for exams and anyone building knowledge on a topic at their own pace, with Gemini adapting to the level and pace of the user over time.
Personalized tutoring has historically been expensive and hard to access. Gemini Study Notebooks puts an interactive learning assistant in the hands of anyone with a phone, in any language, at no cost. For students and self-learners, that is a meaningful shift in what AI access actually means day to day.
AI CODING
OpenAI launched Codex as generally available on the ChatGPT mobile app, bringing its AI coding agent to iOS and Android with one-to-one device pairing, notifications, goals, side chat, and inline review comments.
One-to-one device pairing connects your phone and computer securely, so you can start a coding task on your desktop and continue managing it from your phone without losing context between sessions.
The mobile app now includes goals, side chat, file previews, and inline review comments, bringing it much closer to the full Codex desktop experience for developers who need to work on the go.
Codex on mobile lets you review agent outputs, steer execution, and approve next steps from anywhere, meaning active coding projects no longer require you to be at a desk.
The release brings Codex to all paid ChatGPT users on iOS and Android after a preview period that began earlier this year.
Codex has mostly been a desktop experience since launch. The mobile release changes that by letting developers manage and steer agent work from their phone. The one-to-one device pairing is the standout detail because it makes the phone feel like a genuine extension of the development environment rather than a simplified viewer.
PREMIUM GUIDE
How to remove unwanted digital footprint with Claude.
The step-by-step system for taking your information back.
I have a PhD in cryptography. I've spent years teaching people how digital systems work and where data goes.
I still googled myself last year and found things I didn't know were there.
Data brokers are companies that aggregate public records, social media, voter registration, property records, and purchasing history into detailed profiles of individuals. They sell access to those profiles. Your name, location, email, phone, and household information are almost certainly sitting on dozens of these sites right now.
Getting it removed is possible. The process is genuinely tedious - finding every site, locating their removal links which they bury on purpose, submitting a different form for each one, following up 30 days later when they haven't processed it.
Claude handles most of that work. This guide covers the full system.
One thing to know beforehand: removals take 30 to 90 days per site to actually go through. Claude makes the research and writing fast. The actual deletion is on the brokers' timeline. And some data reappears over time, which means this is an ongoing process, not a one-time fix.
Before you start: two settings to turn on.
Web search. The discovery and opt-out link steps require Claude to actually search the web. Click the + button in any Claude chat and enable Web search before running any prompt in this guide.
Temporary chat. There's an irony worth naming: to remove your personal information from the internet, you'll be pasting some of that information into Claude. Turn on Temporary chat (top right of any Claude chat window) before you start. It doesn't save to your history and isn't used for training. Close the session when you're done.
Find which sites have your information.
With web search on, run this:
Search for my name across data broker sites, people-search databases, and public record aggregators.
My details:
Name: [your full name]
City and state: [your location]
Approximate age: [your age]
Search: Spokeo, Whitepages, BeenVerified,
Radaris, Intelius, MyLife, PeopleFinder,
TruthFinder, Instant Checkmate, and any others that come up.
For each site that returns a result matching my information, list:
1. The site name
2. What categories of information appear
3. Whether there are additional profiles under my name
Group by: confirmed results, likely results, no results found.
This gives you a prioritized list of where your information lives. Start with the confirmed results.
