An LLM is like the engine in a car. Generative AI is the category of vehicle. The AI chat tool is the specific car you drive. You don't need to understand the engine to drive, but knowing the difference helps when people start throwing these terms around.

ChatGPT was first to market and that's why most people started there. Being first doesn't mean best. It is good at many things but is now truly master of none. It has a tendency to agree with you even when you're wrong, rarely pushes back on bad ideas, and produces very surface-level insights by default. The current recommendation is to move off ChatGPT if it's the tool your organization is using. Accurate Networks can help you migrate.

For free models: if you wouldn't post it on a public website or LinkedIn, don't send it. Free tools train on everything you give them, so treat them accordingly.

If your organization has Microsoft Copilot licensed for Teams, it joins your meetings in real time. It takes structured notes as the conversation happens, visible to all attendees. After the meeting, you get a full recap, action items, and coaching insights, who's doing most of the talking, who's falling into the background, whether conversations are happening at a business or technical level. All baked directly into Teams without any copy-paste.

You are not billed per message on a Pro or Team plan. You have a usage window that refills on a rolling basis. When you exhaust it, Claude slows down or blocks access for a few hours until your window resets. There is also a weekly usage cap. Go to Settings > Usage to see where you stand and when your window resets. Check this before any heavy session.

Claude will tell you. You are not permanently locked out, the window resets within a few hours. While waiting: switch from Opus to Sonnet (Opus uses significantly more of your window), start a fresh conversation to drop accumulated context, and check the reset timer in Settings > Usage.

Without personalization, Claude writes for a generic audience. With it, Claude knows your role, your standards, and your communication preferences before you start. Set it once. Never repeat yourself again.

Anthropic offers free official courses at your own pace, no schedule, no account required beyond Claude. A great starting point: claude.com/resources/courses

Think of Claude's models like grades of fuel. A sports car running on premium fuel, that's Opus with extended thinking. Your daily commuter on regular unleaded, that's Sonnet. A farm tractor on diesel doing fieldwork, that's Haiku. All of them work. The right choice depends on what you're trying to do, how fast you need it, and how much of your window you want to spend.

Think of writing a prompt like briefing an astronaut before they climb into a rocket. Once they launch, it's difficult and expensive to add "one more thing." Before they go, give them a single, hyper-detailed message: who they are, what the goal is, how to handle decisions, and how to present the information when they return. The more complete your brief, the better the mission. Every clarification you have to add mid-conversation is a costly radio call when only one side can talk at a time.

Claude can generate interactive, clickable forms mid-conversation instead of asking questions as plain text. You click your answers and it continues with structured input. To trigger this, say: "Before you start, ask me clarifying questions using a form" or "Interview me with clickable options before you proceed." In Claude Cowork, this is called AskUserQuestion and can be explicitly invoked. This dramatically reduces wasted back-and-forth on complex tasks.

Settings > Memory > Enable. Claude extracts facts from your conversations and stores them as a persistent layer. You can view, edit, and delete entries at any time. Memory is not a transcript, it is a fact layer.

Every message includes the full conversation history up to that point. Claude re-reads all of it every time. Long conversations accumulate context, and longer context means your usage window is consumed faster per message. Keep task-specific work focused and short.

A Project gives Claude persistent context scoped to that bucket of work. Upload 5-10 documents, set custom instructions, and then create multiple separate chats, all of which can reference those same documents simultaneously. Claude in a Project only knows what's in that Project.

Imagine joining a conference call with 1,000 people on the line, all of them with multiple PhDs across every department in the world, responding instantly to any question you ask. That is what a cloud-based LLM like Claude offers. Now imagine calling one person instead: a smart professional in a specific field, but not at the PhD level, and the response time depends on how fast their laptop is. That is a local AI model running on your computer. Both exist. They are not the same thing.

Flush out your idea first. Get it into a clear shape. Then use Claude to find the holes. Ask it to challenge your assumptions, identify risks you haven't considered, and argue the opposite position. This is one of the most valuable things these tools can do, and most people never try it.

Companies like Anthropic are releasing fully working features at a pace unlike anything in software history. Some features referenced in this phase were announced in March 2026. Some were released days before this guide was written. If something described here doesn't work exactly as described, it may be a brand-new feature still being refined, not a mistake in this guide. Things improve weekly.
