AI for software developers

A practical course on using AI assistants to write, test, review and explain code without giving up your judgment. Built for working and aspiring developers.

For: Developers, junior or senior, who want to ship better code faster and stay valuable as coding tools improve.

Start lesson 1

When you finish

  • You can sort your own tasks into what AI drafts, what it assists, and what stays yours.
  • You can write prompts that produce usable functions, tests, commit messages and explanations.
  • You can review AI-written code for bugs, security holes and invented functions before it ships.
  • You can keep secrets, customer data and private code out of tools your employer has not approved.
  • You can follow a 30-day plan and describe your AI skills honestly on a resume.

Prompts you can use today

Copy one, replace the [brackets] with your details, and paste it into the AI tool you use. Leave out anything private.

Explain unfamiliar code

Explain what this [language] code does, step by step, for a developer who has never seen this codebase. Point out anything surprising or risky. Do not rewrite it yet. [paste a small, non-sensitive snippet]

Write unit tests

Here is a [language] function and a short description of what it should do. Write unit tests using [test framework]. Cover normal cases, empty input, boundary values and at least two failure cases. List any case you were unsure about. Description: [what the function should do] Function: [paste code]

Debug with evidence

I get this error: [paste the error message]. The code is below. It ran fine until [what changed]. Give me the three most likely causes, ranked, and one check I can run for each. Do not guess at a fix until I report back. [paste relevant code]

Review my change

Act as a careful reviewer. Review this diff for correctness, edge cases, security problems, unclear names and missing tests. Group findings as must-fix, should-fix and nitpick. If you are not sure about something, say so. [paste diff]

Write a clear commit and PR note

Write a commit message and a short pull request description for this diff. Use the imperative mood, a subject line under about seventy characters, and a body that explains why the change was made, how to test it, and any risk. [paste diff]

Refactor in small steps

This [language] function is hard to read. Suggest a refactor in three small steps, each of which keeps behavior the same. Show only step one in full code. Tell me which tests I should run after each step. [paste function]

Plan a feature before coding

I need to add [feature] to a [stack] app. Ask me up to five questions you need answered first. After I answer, propose a plan with the files likely to change, the riskiest part, and how I would test it.

Document an API

Write reference documentation for this endpoint or function: purpose, parameters with types, return value, error cases, and one realistic example. Keep it short and use plain words. [paste code or schema]

Ask the AI tutor
