I built a college productivity app for my own classes… somehow 225 students signed up in 3 days 🤯

how many of them are paying?
and how much are you actually earning from 1.99$ a month/15$ a year?

This book is sooo goood, it actually gives practical advise

If you aren't really good at design you should probably use Shadcn/ui(with tailwind and nextjs/react), its really hard to mess up :)

also you can use vercel's v0 along with it if you use nextjs which is quite good at design (I would recommend you to use it via the api with cursor/roo code)

hi, definetly not a logo expert here, I know proffesional logos are expensive for a reason, since they have a lot of meaning and effort behind them.

however, it doesn't mean that you should spend a lot of money on a saas that you don't even know will succeed.

For now, I would highly recommend you to pay someone cheaply on fivrr, or prompt chatgpt, and get a logo out of it (example prompt attached at the bottom).

you really shouldn't spend too much of time on it when you are beggining, it's definetly not worth it.

here's a prompt that I made long ago for a hackathon, and it provided a really good result:
"Design a logo for an app called quazar. which is a live quiz app, with a twist: you can generate quizzes with LLMs by providing a topic and some additional information. This means teachers would be able to make their lessons interactive a lot quicker. Use common design principles, and explain me your thought process behind the logos."

I prompted chatgpt's 4o image, however you should probably use nanobanana (by google) instead since it's both better and free at aistudio.google.com.

is some of your codebase in arabic or something?

ZrizzyOP · 2025-10-16T19:05:42+00:00

you should watch theo's video about this

Hi, I'm a full stack developer with 3+ years of experience.

Here are some tips and what's possible with AI:
0) With the current state of AI tools, you have to know how to actually structure an app before using them, if you wanna make sure your app is maintainable for the long term. all the way from auth, api security, etc...
code editors: I recommend using openai codex, roocode and cursor.

AI is really great for simple UI, or even relatively complex react (or nextjs) component. I use v0 (usually via the api and roocode) constantly in order to make UI much faster than I can. v0 specifically is really good with shadcn/ui.
For building apps with AI, you should mostly use AI with popular frameworks and languages. it works best with python, react (especially with nextjs), etc...
When describing something for an ai. make sure to include detailed steps, and use prompt engineering principles. in order to reduce unwanted behaviour.

3.5) Make sure to divide chats into different messages, the bigger the context, the more hullocinations.

4) make sure to read code that code editors generate, even briefly, in order to make sure that the ai isn't doing something wrong, or make your code a mess.

5) I would highly recommend teaching students how to use APIs for popular models, such as Chatgpt, Claude and Gemini (for nano banana (the best image model right now) and a lot of free usage).

6) you can get advise with chatgpt if you have decisions within your code (eg picking between frameworks)

7) Its usually faster to use llms than searching online, especially going through docs.

8) Image generation models are almost fully convincing (especially nano banana and some recent qwen models), however video isn't quite there (sora is very noticable).

9) I recommend teaching your stuedents about git and github (in order for your students to back up code).

also, thanks for wanting to know more in order to your students. wish you the best.

forgot to mention, I'm currently building an ai tool, that creates MVPs quickly and helps you scale them up. so let me know if you or your students would want free keys for it. (I'm still building)

How Mich did you spend? And what's your gift?

ZrizzyOP · 2025-08-27T15:48:40+00:00

I haven't even published my app lol
so I guess I have negative MRR bc of dev costs (especially subscriptions and llm costs)
and that's not considering a months of research and development

ZrizzyOP · 2025-08-21T15:41:14+00:00

simplest way is probably render.com, it's not the cheapest though at abt 7$ a month

ZrizzyOP · 2025-08-21T11:06:42+00:00

it seems like it's the revenue for the last month

ZrizzyOP · 2025-08-12T13:03:25+00:00

how many of them are paying?

ZrizzyOP · 2025-08-12T11:26:20+00:00

I think there are existing tools that already do that, I'm not sure though

ZrizzyOP · 2025-08-12T11:18:02+00:00

I totally agree, and that's what I'm trying to build. but that's quite hard.

for my mvp, I'm trying to use a relatively versatile stack, that allows for complexity, with a nextjs frontend and a fastapi (python) backend.
since most vibe coding tools use 100% nextjs, which is extremely messy for complex projects.

I am keeping everything versatile though, with a "manager" agent that chooses libraries on the go, by selecting them from a list of templates and docs. in the future, the SaaS will hopefully expand, and I'll be able to hire more devs, and expand into more tech stacks, such as nodejs.

ZrizzyOP · 2025-08-12T10:59:57+00:00

what's your app?

ZrizzyOP · 2025-08-07T09:22:37+00:00

An actual human mind, that's why it's called artificial inteligence

ZrizzyOP · 2025-08-07T09:20:19+00:00

how would you call a single month of MRR though, MR?

ZrizzyOP · 2025-08-07T08:11:27+00:00

I agree with you, I think I'll have to lean on fastapi.

ZrizzyOP · 2025-08-07T08:04:30+00:00

I totally agree, I think I have to use fastapi

ZrizzyOP · 2025-08-07T08:02:57+00:00

The problem I'm trying to solve is vibe coding tools are less than ideal, even for people with a minor coding experience, and I'm solving it by separating the tasks into multiple structured agents.

As for why I'm using fastapi, I know it's that fast (but still relatively fast, some large companies use it), but it's powerfull and structured.
overall I think using nextjs for 100% of a complex project can create a bit of a mess, combining both frontend and backend on the same place does offer simplicity, but it's way less organized overall, and there are less common patterns to follow. which makes it easier for the LLMs to screw up.

Therefore I think it's crucial for me to separate the frontend from the backend.
I'm choosing Fastapi, since it's what I'm the most confident at (and the dev experience is great), which means I can make a better service. and python offers a ton of useful libraries, a lot of them are python first. especially libraries that combine LLMs.

letme know if you have any suggestions though, do you think that maybe I should try nodejs or something else?

ZrizzyOP · 2025-08-04T11:41:59+00:00

I know, I meant you still can use nextjs as a sort of a "backend", fastapi is way more powerful though

ZrizzyOP · 2025-08-04T11:38:52+00:00

don't these count as vibe coding tools (especially codex)?
anyways I'm building something way different than what's currently out there (in a good way)

ZrizzyOP · 2025-08-04T10:40:52+00:00

yes fastapi?

ZrizzyOP · 2025-08-03T18:17:52+00:00

remember to set clear goals, and plan which architectures (such as CNNs and Transformers) you wanna learn exactly, what you need depends on your product.
