Overview
About ChatGPT: Deep Dive
The advanced tier for people who already chat with ChatGPT every day. Go deep on the power surfaces: picking the right model, building durable workspaces, working with your own files and tools, and running multi-step work with a review point.
What you will be able to do
By the end you will be able to match a model to a task deliberately, build a Project and a custom GPT for recurring work, ground answers in your own files and connected apps, and run an agent-style multi-step task with a checkpoint before it ships.
Classwise is built for working professionals and teams learning AI tools for their current job: no coding background assumed, the price on the page before your email, and every number shown sourced. Pick the course that matches the tool you use at work, learn a few minutes at a time, and finish with a verifiable certificate you can share.

One workflow from many surfaces
The capstone combines Projects, custom GPTs, connectors, memory, and agent mode into a single working pipeline, with a checkpoint where you review before it ships.
Format
How the lessons work
Short, practical, and written against the live tool, the same for every Classwise course.
A few minutes at a time
Every lesson is short and practical: read it or listen to it on any device in a few minutes, then use it in your own work. Progress saves automatically, so you can stop when work interrupts and pick up where you left off.
Written against the live tool
Each course is written against the live product it teaches: real buttons, real menus, real plan limits, with dated sources you can check. Anything older than about 90 days is re-verified before it stays on the page.
Reviewed before it ships
Every lesson passes a content lint, a readability check, and a visual review before it ships. AI drafts, a human reviews and owns the result.
