How to Use AI in Excel to Create and Edit Spreadsheets [Complete 2026 Guide]

78% of organizations worldwide were using AI in their workflows as of 2024, according to McKinsey’s Global AI Survey,, and Excel remains the most widely used data tool in business. Yet most people still build spreadsheets the hard way, manually typing formulas, cleaning data by hand, and formatting cells one by one. Microsoft’s built-in Copilot can help, but it costs $20/month on top of your Microsoft 365 subscription, and while it can now create basic spreadsheets with Edit with Copilot, it works best when editing existing files. The best way to use AI with Excel in 2026 is Fello AI. It generates complete, downloadable .xlsx files with working formulas, formatted […]

Claude Computer Use: What It Is, How to Set It Up, and What You Can Actually Do With It

Claude can now take control of your Mac, clicking buttons, typing text, opening apps, and completing tasks on your screen while you step away. Anthropic launched Claude computer use on March 23, 2026 as a research preview for Pro and Max subscribers, and it changes how you interact with AI. The company announced the feature alongside Dispatch, its new phone-to-desktop task delegation system. Instead of copying and pasting between Claude and your apps, you simply tell Claude what you need done, and it does the work directly on your desktop. This isn’t a gimmick or a developer-only tool. Whether you’re a student juggling research papers, a marketer managing campaigns across […]

How to Use Claude Code on Your Phone: 3 Methods That Actually Work

One command, one QR scan, and your terminal session is live on your phone. No VPN, no port forwarding, no third-party tools required.

How to Create Your Own Claude Code Skills That Actually Work

Claude Code skills can cut the time spent on repetitive AI tasks by 70% or more, and most people using Claude Code have never touched them. A skill is a saved set of instructions that Claude follows the exact same way every time; you invoke it with one short command, and it just works. We tested five custom skills built specifically for non-technical users: a content writer, a small business owner, a marketing manager, a teacher, and a student researcher. None of them had a coding background. All five had working skills inside an hour. This guide shows you exactly how they did it, what to include, and the one […]

A developer at a dark ultrawide monitor setup with glowing code windows — illustrating the best Claude Code skills picked by use case

The 30 Best Claude Code Skills to Add (Picked by Use Case)

Most Claude Code users discover skills by accident. Someone mentions a /skill-name command, it works brilliantly, and suddenly they want more. What most guides miss is that the best Claude Code skills depend entirely on what you actually do. A developer, a teacher, and an ops manager all have very different workflows, and the skill that saves one of them hours a week might be completely useless to the others. This guide covers the best Claude Code skills by use case, starting with the built-in skills you already have and may not know about, then moving into the top picks for developers, teachers and students, document workers, writers, business teams, […]

Switching from ChatGPT to Claude: Why, How, and What to Expect

Switching from ChatGPT to Claude has never been more popular. More than 700,000 users have reportedly ditched ChatGPT as part of the growing QuitGPT movement, and Claude has surged to the top of Apple’s U.S. App Store free rankings for the first time, with paid subscribers more than doubling since January 2026. ChatGPT app uninstalls spiked 295% in a single day following a string of controversies around OpenAI’s ethics decisions and GPT-5.2’s much-criticised writing quality. Whether you’re leaving out of principle or simply curious whether Claude is better for your needs, making the switch is easier than you might think. This guide is written for ChatGPT users making the move […]
