Not to disparage, but I wrote:

"Using the attached image as a stencil/background - please generate a QR code for https://XXX"

into ChatGPT and got something valid that looks similar in style to your offering.

I think the age of trying to wrap a highly focused AI task in a SaaS has come and gone.

romanovcode•1h ago

Jokes on you, this is the exact prompt OP uses in the BE lol

gnfargbl•1h ago

I don't disagree, but remember the lesson of https://news.ycombinator.com/item?id=9224 -- historically, people have been willing to pay for convenience.

tlonny•1h ago

I would argue that my proposed flow is far more convenient. I don’t have to sign up, enter payment details and I can interface in plain English.

cyberge99•52m ago

Many people are not as skilled as you. No pun intended.

janpmz•53m ago

With simple prompting it works sometimes but less reliably. I implemented a healing and strengthening algorithm which can improve codes that don't scan quickly.

zerolunier•1h ago

yo, design looks dope, 100% gone use it for my business

jruohonen•1h ago

Nice idea! Simple but no one has done it previously, so that counts. (As per some posts, I stand corrected, but still, I believe no one has done it as an implementation.)

jeroenhd•57m ago

The concept itself has been done a few times before. This Reddit thread has an explanation on how you can generate these yourself: https://www.reddit.com/r/StableDiffusion/comments/18aoqs0/co...

The good old https://huggingface.co/monster-labs/control_v1p_sd15_qrcode_... model and its predecessors also help.

The technique works for other black-and-white masks too: https://reticulated.net/dailyai/ai-generated-qr-codes-with-s...

Good looking qr codes is nice, but doing them using AI feels like a huge waste?
