Sorry you hit some bugs, I haven't seen these yet. Will look at the logs and try to see what's going on.

Looks like it was just a display issue. Your card successfully saved both addresses and is queued for printing!
Thanks! Yeah your margin calculations are roughly correct.

This is a fun side project built for myself, that I thought others might enjoy -- so maximizing revenue hasn't been a huge part of planning.

I plan to market this on traditional channels (Reddit, X, etc) and maybe test out some paid ads if the CAC is <$3.50 -- open to ideas!

That's a valid concern. There's definitely no voice cloning or information being sold from this app.
Good idea making the example more prominent. Capturing email to send a reminder for birthday/etc is smart and nice way to have a "lead magnet" actually add value. thank you
Fixed the upload size bug on homepage
Thanks! Will look into these potential issues
Love that idea! Was thinking it'd be neat if there were little signs at museums/landmarks/etc so people could pull up pre-made templates or upload their own photo to quickly send a card.
Thanks! I agree that handwritten notes are special. My intent was not to replace that so much as offer another way to make a physical note feel personal, while removing some of the "burdens" of sending traditional mail.

It was also just a fun way to learn how to connect all these technologies and be able to trigger an event in the real-world from a few lines of code.

Appreciate the feedback.

Show HN: Scout – Identify any vehicle with AI

https://apps.apple.com/us/app/scout-vehicle-identifier/id6472626789?uo=2

I've wanted to build this side-project for years - but training a model on every car was prohibitively expensive and complicated to do. It became trivial with the launch of GPT-4 Vision API. Some iteration on the prompt was required until it became pretty dang accurate. App is built 100% in SwiftUI. Would love your feedback on usefulness and price (its free up to 3 identifications).

I enjoy looking for houses in my neighborhood and imagining what I would do if I were to buy it and fix it up.

So I built a quick little app that can reimagine a house from a single photo.

https://dream-house.clarkdinnison.com/

It uses Replicate API to send your photo to an AI model that is specifically good at detecting straight lines/edges (perfect for architecture applications) - then layers on a remodeling prompt I iterated on for a few weeks.

Show HN: Visualize your house in different styles

I often find myself wanting to reimagine what a fresh coat of paint and some modern touches can do for houses in my neighborhood. This was a fun tool I made to solve that.Built with Replicate, Vercel, Next.jsP.S. Still learning lots about how to best prompt the model to get best results. Would love to hear ideas/feedback.

Over 75% of products we enjoy today end up in a landfill or are incinerated. We're building new infrastructure and systems to change that.

Our enterprise circularity platform already helps brands like PepsiCo, Walmart and Ball Corp to recover and reuse their materials with full traceability.

All people whether residing in Finland or just visiting have the right to enjoy nature anywhere in the Finnish countryside regardless of land ownership.
I was researching help desk tools and stumbled upon Zendesk Alternative, the fake band from Seattle that helps Zendesk own the top search result. Love the creativity.
Plastic only becomes waste and ends up in the ocean if it is not collected properly. We're solving this problem at Replenysh.
