Micro-internship brief ≈17h across 3+ days — actually use it dailybuilder

Build a Chrome extension that fixes a daily annoyance

Extensions are the smallest real software you can ship: they run in your actual browser on your actual problems. Build one (AI-assisted) that fixes something that annoys you daily — then use it for 3 days and report honestly.

The work brief

  1. 01Pick a daily annoyance: hide distracting feeds, auto-fill a form you always type, count study time on sites, highlight keywords on job boards.
  2. 02Build it with AI help: manifest.json v3, content script or popup. Load it via chrome://extensions developer mode.
  3. 03Actually use it for 3 days. Log where it broke or annoyed you, and fix at least one issue.
  4. 04Push code + README with install steps to a public repo, and record a short demo video.

What you’ll produce

5 deliverables

Submission standard

Submit the repo, a demo video link, a screenshot of it installed and working, and your 3-day usage log. Include your AI workflow: tools, best prompts, and what you changed from the AI’s output. Date each day in your usage log and reference the commit where your fix landed; the repo must show the build and the fix as separate commits.

  • The daily annoyance and how the extension fixes it

    Short answerRequired

  • Public repo with code + install README

    Public repo with code + install README — commit history should show the initial build AND your during-use fix as separate dated commits, not a single paste. A one-commit dump fails the authenticity gate.

    Public linkRequired

  • Public demo video of the extension working

    Public linkRequired

  • Screenshot: extension loaded in chrome://extensions and doing its job

    Image uploadRequired

  • Your 3-day usage log: where it broke, what you fixed

    Your 3-day log with a dated line per day (real dates), what broke each day, and the fix you shipped — reference the commit where the fix landed.

    Written responseRequired

You’ll complete these inside your private workspace.

How your work is evaluated

The passing benchmark is 70/100.

Working extension

29%

The demo and screenshot show it installed and doing its stated job.

Real usage

29%

The 3-day log shows genuine daily use with honest friction.

Code & docs

14%

The repo has working code and install steps someone else could follow.

Really used over days

29%

If the install screenshot/demo don't show YOUR browser doing the job, the log lacks real dates, or the repo is a single dump with no during-use fix commit, this fails.

How we grade your AI usage

30% of your score

Using AI is the point — it’s the skill this certificate proves. You’ll answer three short questions about how you used it: what you asked, what was wrong with its first answer, and what you changed. Specific, honest answers score high. “I pasted the brief and submitted the answer” scores near zero.
