FIRST AI APP BUILT. ZERO CODE. FULL SEND.

How I built ThoughtArchive using AI tools and prompts. No full-stack stress. Just raw output.

June 25, 2025

WEEK 1 BUILD LOG

PROJECT: THOUGHTARCHIVE
STATUS: LIVE MVP
STACK: CURSOR / SUPABASE / CHATGPT / TAILWIND

This was the first AI-powered app I’ve ever shipped without touching full-stack code. Just AI tools, real prompts, and clear execution.

ThoughtArchive lets you speak a thought. It then tags and organises it using ChatGPT, and stores it in Supabase. Simple idea. Functional result. Real progress.

It’s not perfect. But it works. I built it. And now it’s out there.

THE STACK THAT SHIPPED

  • Cursor – AI coding and debugging

  • Supabase – Postgres backend with row-level security

  • TailwindCSS – Styling without wasting time

  • OpenAI (GPT) – Tagging and grouping engine

  • Notion – Product documentation and delivery hub

BUILD BREAKDOWN
STOP ASKING. START ASSIGNING.

Most people treat ChatGPT like a search engine. I don’t. I treat it like a teammate.

Instead of writing:

❝

Tag this thought

I now write:

❝

You are an AI thought organiser. Your job is to group and tag this transcript. Return it as JSON so it can be saved in a structured format.

That small shift made a massive difference. More reliable results. Fewer hallucinations. Faster workflows.

Clarity in. Clarity out.

STARTER KIT IS LIVE

I turned the full setup into a product. If you want to build your first AI-powered tool without code, this is the one.

What you get:

  • Full Notion walkthrough

  • Supabase schema and RLS setup

  • Copy-paste prompts for GPT and Cursor

  • Step-by-step build checklist

  • Free lifetime updates

PROMPT OF THE WEEK

You are an AI thought organiser. Analyse the following transcript and return a group and 3 to 5 tags. Format the response as clean JSON.

This is the engine behind the tagging system in ThoughtArchive. It handles every input the same way, every time.

WHAT’S COMING NEXT

  • Voice input using Whisper

  • Editable tags and groups

  • Export to Notion or JSON

  • Chat-style reflection interface

  • Cleaned-up mobile UI

All of these updates will be added to the same kit. No extra payments. Just more value each week.
