Real AI agent use cases, with sources and setup prompts

Build a phonics reader for your child and let Claude or ChatGPT import books into it

A parent built Yara Reads, an open-source early-reading app where a 6-year-old taps words to hear each phoneme and read alone. It has an MCP connection, so Claude, ChatGPT or Grok can take a PDF or phone scans of a book you own and import it into your child's private library.

  1. Gather your sources

    Collect the papers, notes, links or files you want to work from in one place.

  2. Load them into the tool

    Open Claude, ChatGPT, Grok and add your sources. Keep the original files so you can check claims later.

  3. Ask focused questions

    Ask for summaries, comparisons or connections with citations to the source passages.

  4. Verify and save

    Spot check claims against the sources, then save the output as notes you can reuse.

Please:
1. Ask me 3 short questions about my situation (accounts I have, budget, what I want the output to look like).
2. Propose a step-by-step plan using these tools or cheaper alternatives, with the time and cost of each step. Use official pricing pages; say "check pricing" if unsure.
3. Then do the setup with me one step at a time, waiting for my OK before anything that sends messages, posts publicly, spends money or deletes data.
4. Finish with a checklist to run it again next time.
