A prompt is the message you send to the AI tool. Copy the one on this page, put your own details where it asks, and read the answer before you act on it.

Build a simple web app for my 5-year-old. My child picks a number and the app shows the right Numberblocks character image to draw or color. If there's no image for that number, let my child generate one. Keep it big, simple and kid-friendly.
Try this in:
Sends the Recreated prompt shown above. ChatGPT and Grok open with it filled in, and ChatGPT may send it straight away. Gemini and Claude open empty, so we copy the prompt for you to paste. Every button also copies it.
The source used Lovable, Cursor and n8n, which can take actions in a browser or app. These are general chat tools, so results may differ, and a normal chat may only give you a plan.

Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish. Goal: Build a simple kid-friendly web app that finds the right picture for a number, without me writing code. Questions to ask me first: - What should a child see first, and how old are they? - Where do the images come from, and are you allowed to use them? - What should happen when no image exists? Inputs (fill in or confirm): - Image source: [SITE OR FOLDER] - What to do when there's no image: [GENERATE / MESSAGE] - Limits on image generation: [LIMIT] Rules: - Start with one screen: pick a number, see one image. - Only use images from the source I name, and respect its terms. - Add a limit on generated images so costs stay low. - Explain each change in plain words before making it. Checkpoint: After the first version works for numbers 1–10, stop so I can test it with my child. If you get stuck: If scraping the image source fails, tell me why instead of retrying blindly. Verify before you finish: Test five numbers, including one with no image. Output: A working app link and a short list of what it can't do yet. Done when: My child can pick a number and get the right picture.

Outcome
Harshal Patil kept searching sites and Google Images for the right Numberblocks picture for a 5-year-old son to draw or color. In 45 minutes, Patil built a web app with Lovable: pick a number and get the right Numberblocks image, and if none exists for that number (for example, 555), generate one. A bulk image scraper didn't go as well. Cursor didn't get the scraper right on the first attempt and was hard to debug, and an n8n workflow was hard to follow and did not run. Patil added rate limiting and made the single-image finder the main mode.
Evidence: Screenshots or logsThe source shows screenshots, a transcript or the AI's output.
Known limitations
PartialThe source says it only partly worked, or had a significant problem a person had to deal with.
What went wrong: The Lovable app worked, but the bulk image scraper failed with both Cursor and n8n.
