What AI chatbots can actually help with: realistic use cases
AI chatbots have become remarkably useful tools, but the gap between what they can actually do and what people think they can do is still pretty wide. So let’s cut through the hype and talk about what you can realistically count on them for right now. These aren’t science fiction capabilities—they’re the things that work well enough today that they’ll save you time and mental energy.

What are tokens and why do AI tools count them?
If you’ve spent any time using AI tools lately, you’ve likely run into the word “token.” Whether it’s a warning that your “context window” is full or a pricing page explaining that you’re charged per thousand tokens, the term is everywhere. But what actually is a token, and why can’t these advanced systems just count words like a normal human?
At its simplest, tokens are the fundamental units that an artificial intelligence “reads” and “writes.” While we see words, AI models see a stream of these numeric fragments. Understanding how they work isn’t just a fun technical trivia point—it’s the secret to understanding why AI sometimes makes mistakes, how it “remembers” your conversation, and why it costs what it does.

What does 'training' an AI mean?
When we talk about “training” an AI, it’s easy to picture a digital student sitting in a classroom, absorbing facts from a textbook. But the reality is both more mechanical and more fascinating than that. At its heart, training an AI is about teaching a massive mathematical model to recognize patterns in information so it can predict what should come next.
Whether it’s the latest ChatGPT model from OpenAI, Anthropic’s Claude, or Google’s Gemini, every frontier model goes through a rigorous, multi-stage process before it ever sees a user prompt. Understanding this process helps explain why these models are so capable, but also why they sometimes struggle with simple facts.

What does it mean when an AI is open source vs. closed?
When you start looking into the world of artificial intelligence, you’ll quickly run into two camps: the “open” crowd and the “closed” crowd. Companies like OpenAI, Anthropic, and Google generally keep their most powerful models behind a digital curtain, while others like Meta and DeepSeek release models that anyone can download and run.
At its simplest, this debate is about who gets to see how the engine works and who is allowed to drive the car. But the lines have blurred, and a new term—“open weight”—has become just as important for understanding how your favorite AI tools actually function.

What happens when a website says your connection is not private?
You’re browsing the web, minding your own business, when suddenly a giant red or gray warning blocks your path: “Your connection is not private.” It’s an intimidating screen that feels like a digital “Keep Out” sign. But what is actually happening behind the scenes, and is your computer really in danger?
In short, your browser is acting as a security guard. It’s telling you that it can’t verify the identity of the website you’re trying to visit, which means any data you send or receive might not be as secure as you think. It’s less about a virus on your machine and more about a broken link in the trust chain between you and the website’s server.
