My experience was a bit of a disaster.

It's worth noting that it's only at the end that it turns out you have 3 options for using the rows (you can't say use row 1&2 caps but row 3 lowercase)

For whatever reason it really struggled to detect the cross hairs. It thought the top right cross hair was the O.

I had intensely compress the black white range to make it detect at all.

What should it look like btw?

Also even though it detected A thru F great it kind of fell to pieces down the page suggesting that the registration isn't good enough to detect each block. Maybe let people mark the cross hairs manually?

More registration marks and ones that are more distinct than cross hairs would likely help. I used a high quality scan! So registration should have been muche asier than a photo.

I don't really know what's wrong!



The website does say that it was ‘vibe coded’[0] so perhaps the author didn’t test it very thoroughly? They apparently do ‘vibe coding’ courses so.. that’s something.

It's really impressive for what it is.

I tried it various pens and paper sizes and printer scales. And it suddenly worked but only if scanned at low res (200DPI).

Still I got a partially working font at the end


For sure! I was so surprised to see that this was done all in browser. I mean there’s no reason that shouldn’t be possible in 2026 considering there’s services that do this server side, but still it’s always impressive when something like this comes along.


It's not a course.

What I do is free and intended to be workshops for non-technical users to understand the power of technology rather than slamming it in their face.


ugh. i came to see why this site failed completely to work as expected. turns out that a human has barely been anywhere near it and thinks that delivering non-working slop is fine. what a waste of my time and printer paper.


Try it again. Made some beefy updates earlier today to catch outliers.


Yes seems to be working well now!
