Give an everyday object a persistent AI personality with a speaker and an app

A builder wanted to give everyday objects lasting AI identities and ended up making an Android app. It started with a $13 Bluetooth speaker with a microphone the builder already owned, which became Greg, a sarcastic ancient rock that is secretly affectionate.

What they did

A builder wanted to give everyday objects lasting AI identities and ended up making an Android app. It started with a $13 Bluetooth speaker with a microphone the builder already owned, which became Greg, a sarcastic ancient rock that is secretly affectionate.

Result (as claimed)

Greg talks back through the speaker with a consistent personality, and the experiment grew into a full Android app.

Tools they used

Android

Cost: Pricing depends on the tools you pick; check each official pricing page.

Set it up

  1. Write a one-page brief

    Describe the app in plain words: who it is for, the 3 core screens or actions, and what "done" looks like.

  2. Start the project with your agent

    Open Android and paste the brief. Ask it to propose a stack and a file plan before writing code.

  3. Build one slice at a time

    Ship the smallest working flow first, run it, then add features one by one. Commit after each working step.

  4. Test it like a user

    Click through on desktop and phone. Ask the agent to add basic tests and fix anything that breaks.

  5. Check security and ship

    Keep keys in environment variables, check auth and database rules, then deploy and share the link.

Copy the full setup prompt

Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.

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.
