The "build it yourself" prompt: stop paying $15/month for a prompt in a cute logo
Before you subscribe to one more AI app, run it through this — half of them are just a prompt someone wrapped in a logo.
okay, real talk: the average american is spending around $219 a month on subscriptions — and when you ask them, they guess $68. We are all quietly bleeding money we can't even see, and the newest trap is AI. So many of these shiny new AI apps are just a single prompt wrapped in a pretty logo, charging you $15 a month for something you could build yourself in five minutes.
so here's the one question I ask before I buy any new tool: could I just describe what I want to Claude or ChatGPT and get most of the result myself? If yes — don't buy it. Build it. It's yours forever, for free, in any color you want. This is the exact starter prompt I use to find out.
The build-it-yourself starter prompt
Paste this into Claude or ChatGPT You are my no-code product builder. I want to build a simple, personal version of an app instead of paying a monthly subscription for it. Here's the app I was about to pay for: [DESCRIBE THE APP — e.g. "a meal-planning app" or "an AI journaling app"]. What I actually want it to do for me: [LIST THE 2–4 THINGS YOU'D ACTUALLY USE — e.g. "give me a week of dinners, a grocery list, and swap meals if I don't like one"]. My vibe / must-haves: [ANY PREFERENCES — colors, tone, how simple, on my phone vs. Laptop]. Do this in order: 1. Tell me honestly whether this is something I even need to "build" — or whether I can just get the result by chatting with you each time. If chatting is enough, give me the exact reusable prompt I'd paste in to get it, and stop there. 2. If a little tool would genuinely help, build me the simplest possible version I can use TODAY — a single self-contained HTML file I can open in my browser (or save to my phone home screen), no logins, no accounts, no coding on my end. Style it to match my vibe above. 3. Give me the full copy-paste code in one block, plus dead-simple steps for a non-technical person to open and use it. 4. Flag anything that would actually be hard, unsafe, or require real security (payments, other people's data, private info) — because that's the ONLY kind of thing worth paying a real company for. Keep it beginner-friendly and be honest with me: if buying is genuinely smarter than building, say so and tell me why.
How to use it
Paste the whole thing into Claude or ChatGPT (Claude tends to be great at building the little html tools).
Swap the [brackets] for your real app — the thing you were about to pay for, what you want it to do, and your vibe.
Read its honest verdict first: sometimes the answer is 'you don't even need a tool, just reuse this prompt' — and that's a win, you just saved $15/month.
If it builds you a file, copy the code, save it as something like meal-planner.html, and double-click to open it in your browser. On your phone, save it to your home screen so it feels like a real app.
Ask follow-ups like a friend: 'make it pink,' 'add a button to email me the list,' 'make the font softer.' Keep tweaking until it's yours.
that's it — that's the whole secret. Most of what we're paying for isn't hard, it isn't even secure; it's just packaged well. Once you start asking 'could I just build this?', you can't unsee it. Go try it on ONE subscription this week and tell me what you built — I want to see it.
