Watch the episode above for the visual explanation, then use the notes below to revisit each idea, example, and practical move.

01

A Huge Context Window

Claude can take in a massive amount at once - a long contract, an entire codebase, or hours of meeting notes - and reason over all of it together. Drop it in and ask about any part; it won't forget the start by the time it reaches the end.

Huge context, nothing dropped

02

Drop In Your Files

Upload PDFs, images, and spreadsheets right into the chat and ask questions about them. Hand Claude a contract and ask what you are agreeing to, or a sales sheet and ask for the trend. No retyping required.

Upload, then just ask

03

It Can Actually See

Claude has vision, so it reads charts, screenshots, diagrams, and even messy handwriting. Snap a photo of a whiteboard, a confusing error screen, or a graph, and get a plain-language explanation back.

Show it, don't describe it

04

Search The Live Web

When a question needs current information, Claude can search the web instead of guessing from older training. Ask about a recent release or a today fact, and it looks things up before answering. Less stale, more checked.

Looks it up, not made up

05

Live Artifacts Beside You

Artifacts give Claude a panel next to the chat to build something real: a polished document, a chart, or a small working app you can click. You watch it take shape and ask for tweaks as the preview updates live.

A live preview, right there

06

It Runs The Numbers

The analysis tool lets Claude actually run code to crunch your data rather than eyeball an estimate. Give it a spreadsheet of orders and it computes the real totals, averages, and outliers. Calculated, not guessed.

Calculated, not estimated

07

A Sharp Writing Partner

Claude is genuinely strong at long-form writing and editing. It drafts an article from a rough outline, rewrites a clunky paragraph, or tightens a bloated email to its point. Tell it the goal and it shapes the words.

Draft, rewrite, tighten

08

Make It Sound Like You

With custom style you set how Claude should write, so replies come back in your voice. Show it a few samples or describe the vibe you want, and from then on the drafts already read like you wrote them.

Replies in your voice

09

A Real Coding Partner

Claude writes, explains, and debugs code across many languages. Paste a broken function and it finds the bug, or describe a feature and it drafts the code with notes. Great whether you are seasoned or just learning.

Write, explain, debug

10

It Admits Its Limits

Instead of confidently inventing facts, Claude flags uncertainty and pushes back when something looks off. If your premise is shaky or the answer is genuinely unclear, it says so. That honesty makes it safer to trust.

Honest over confident

11

Projects Remember Your Stuff

A Project is a saved workspace that holds your files and instructions in one place. Drop in your brand guide or reference docs once, and every chat inside that Project already knows them. No re-explaining context.

A workspace with memory

12

Build Your Own Assistant

Turn a Project into a reusable custom assistant for one recurring job. Set up the files and instructions for, say, weekly report writing, then return to it again and again. A purpose-built helper, ready when you open it.

One job, done your way

13

Set Standing Instructions

Give Claude system instructions that apply automatically to every chat. Tell it once to use plain English, stay concise, or follow your formatting rules, and it remembers across conversations. Set the rules once and they stick.

Set the rules once

14

Keeps Big Projects Straight

Claude handles large codebases and long technical docs without losing the thread. Feed it a sprawling spec or a tangle of files and ask how one piece affects another. It tracks the connections across the whole thing.

Holds the whole picture

15

Claude Code In Your Terminal

Claude Code is a developer tool that runs in your terminal and works with your real files. Ask it to add a feature or fix a bug and it reads your actual project and edits the code in place. This one is for the command line.

Edits your real files

16

Describe It, Get An App

With Claude Code you can build a real working app or website by describing what you want in plain English. Explain the pages and features and it writes the files, wires them together, and gets it running.

From words to working app

17

Connect Your Tools With MCP

MCP is a standard that connects Claude to your own apps, data, and tools. Hook it up to your files, a database, or a service you use, and Claude works with them directly. A technical setup that makes Claude a hub for your stack.

Plug in your own tools

18

It Works Agentically

Claude can act like an agent: it plans a multi-step task, takes the actions, checks its own work, and iterates until done. Hand off a goal and it works through the steps, course-correcting like a junior teammate.

Plans, acts, self-corrects

19

It Can Use A Computer

With computer use, Claude can operate apps on screen the way a person would, moving the cursor and clicking through real interfaces. It is advanced and developer-oriented, pointing at Claude doing busywork inside real software.

Drives the screen itself

20

Ship Real Software, Claude Code

The peak: with Claude Code you go from a plain-English idea to working, shipped software. Describe the product, let Claude build, test, and refine it, and you get something real that runs. Right where this series heads next.
