Learn Replit in 5 minutes.
Replit is a cloud platform where you build, run, and deploy software entirely in the browser. The lesson drills the split between Agent and Assistant, prompting an app into existence, and what it takes to put it on a real URL.

Agent, Assistant, or just you?
Replit gives you two AI helpers with very different appetites, and knowing which one to summon is most of the skill. One builds; one tweaks.
Builds from scratch
Describe an app and Agent plans it, scaffolds the project, installs packages, and iterates until it runs. It's for creating whole features or entire apps, not for renaming a variable.
Quick targeted edits
Assistant makes small, scoped changes to code that already exists: fix this bug, restyle that button. Lighter and faster than Agent, and the right call once a project is up and moving.
Ship to a URL
Deployments take the project you just built and put it on the public internet, with options from static hosting to autoscaling services. The distance from working code to live URL is a few clicks.
What you will do in the lesson
You answer and try things. Nobody demonstrates at you for five minutes.
- Describe an app worth building. You'll write the kind of prompt Agent can act on: concrete features, a clear user, a first version that is deliberately small.
- Watch the plan before the code. Agent proposes a plan first. You'll practice catching scope creep in that plan instead of in the finished app.
- Route a change to the right helper. Given a list of follow-up tweaks, you decide which go to Assistant and which genuinely need Agent. Cost and speed hang on this call.
- Debug from the console. When the app misbehaves, you'll practice pasting the actual error rather than describing the symptom, and see how much faster that resolves.
- Reason through a deployment. Static, autoscale, or reserved: you'll match app types to deployment types so the shipping step is a decision, not a guess.
Before you start
Is Replit only for beginners?
No, that reputation is outdated. It's a full cloud development environment with real deployments, databases, and an agent that handles multi-step builds. Beginners like it because nothing needs installing; professionals use it to go from idea to hosted app in one sitting.
Do I need a Replit account to take this lesson?
No. The lesson runs right here in the page with no signup and nothing to install. If you want to build your own project afterwards, Replit has a free way to start.
What's the difference between Agent and Assistant again?
Agent is for building: it plans, creates files, installs dependencies, and keeps working until the app runs. Assistant is for adjusting what exists: small edits, quick fixes. Using Agent for tweaks is the most common and most expensive beginner mistake, which is why the lesson drills it.
I code locally in VS Code. What would Replit add?
The pitch is the collapsed distance between writing and shipping: environment, packages, database, and hosting all live in one place. For side projects and prototypes that means no setup and no deployment yak-shaving. Your local editor still wins for large existing codebases; Replit wins for going from zero to a URL.
