A platform for digital asset management, review and workflow. Current features focus primarily on review of images aimed at automotive configurators.

The problem is generic, however, our USP is we have a couple of enterprise customers that upload packs of 60k+ assets for a round, and thus we aim to help discover what demonstrably changed.

A bit like Github, only working with images, videos, and other digital assets rather than text files.

I’ve created Pixie, a platform to employ and track your kids work. For families with a business, it helps reduce tax burden and fund a child’s Roth. I’m a physician with some 1099 income, built the platform myself because my kids help with my side projects, and have since onboarded CPAs who now offer it to their clients. I saved 5k this year on my own taxes by employing my kids and it has funded their Roth. Soon afte…

What is the maximum amount a kid can earn yearly?

No limit but for staying under them paying tax it’s the standard deduction (15k). And you can only contribute $7500 (2026) to their Roth.

A reasonable amount depends on their age but somewhere between 7500-15000 is a good amount and maximizes benefits.

I run Brick Ranker a website that tracks the value of LEGO sets and minifigures. You can also signup and catalogue your own collection so that you can track it's value or just see what you own.

It makes around $500 a month from a mixture of adsense and affiliate schemes. Would be good if I was making more but I've automated most it so I spend maybe 1 hour on it a month.

I run a dead-simple, one-time, online fax service called JustFax Online[0]. While I don't have a recurring revenue as I operate one one-time payment, for the past months I have been consistently grossing over €500/mo. This also brings tears to my eyes, as I remember[1] browsing these threads and being amazed (still am) by all the people who make side projects and make money from them, and at the same time thinking th…

TIL you can still buy fax machines!

We have one in our office.

I built ChatKeeper because I wanted to treat my ChatGPT history like a local knowledge base, with local-first access to my data.

It’s a command-line tool (GUI in progress) that takes a full ChatGPT .zip export and syncs it with local Markdown files. You can move and rename them freely and they will stay in sync on future runs.

It pairs well with tools like Obsidian and lets you link your own notes to specific conversations or even points within them.

Revenue is modest but growing month over month. It’s a one-time purchase, not a subscription.

Most users so far are researchers and other ChatGPT power users who already live in Markdown or want to do things like curate and compress the context of very long-running conversations.

Earlier quoted context omitted.

Everything comes and goes. HN is no exception. With that in mind does it matter for you? Are you here because HN is at its peak? If commenting here makes you life better a bit keep doing that. If not then just don't and go somewhere else. Or stop using the internet altogether and just became goat farmer. Do what makes you happy and not what crowd thinks will make you happy!

Crafting CSVs is what makes me happy.

Awesome! I found it interesting. Keep doing that :)

An audiobook streaming service that focuses on timeless classic works in the public domain.

I do everything from building the app to the audio engineering.

One thing I'm especially proud of is the restoration I did on the "War of the Worlds" 1938 Radio broadcast. I'm really happy with how it turned out. I've made it temporarily free to listen to [1] in case anyone is curious. You should compare it with the original [2] and let me know what you think.

Here’s my own side project that’s been earning a bit on the side: I built DedupX, a macOS app for finding duplicate and visually similar files fast - especially useful for photographers and anyone with big local storage collections. What it does - Exact duplicate detection using incremental hashing so it doesn’t have to fully load huge files. - Perceptual image matching finds similar images even if they’re resized or…

How do you market it, through social-media or are there dedicated channels for sharing awareness for such Mac Apps, if you don't mind sharing?

I mostly shared the launch post and ran promo campaigns on Reddit, ProductHunt, LinkedIn, Discord and even tried HN (got no replies here -‿-"). Since then, its mostly word of mouth.

Thanks to my customers' feedback, I've made a lot of improvements to the app as well. Feels good getting positive feedback and hearing from people about their use-cases. :)

I made https://meetinghouse.cc as a way for twitter people to put themselves on a map and write a bio, and what they're looking for. It's a way to find and be found, if you want to see who's interesting nearby for friends, dating, new parents meeting new parents, etc.

Pins cost $12, there are 474 pins placed so far. This keeps the quality high (there are no spam pins, only real people) but will fundamentally limit the growth, I think.

https://fivethreeone.app/ a weightlifting app for 5/3/1 has been earning me ~$1000 a month for over two years now. I'm actively working on a successor that allows you to create your own custom workout programs using formulas: https://vis.fitness

This is a perfect example of taking a simple idea and elevating it/ executing it well. Well done!

As someone that has used 531 for a while, I thought an app like this would not add much value. I mean, we can all track our progress in a spreadsheet. But I must say that it looks great.

This stuff is inspiring to see..
