redditBuilt a data labeling tool as a side project, it somehow has real users now Started it on a Tuesday night. My cat was on my keyboard. I was annotating training data for a fine-tuning job at work and the whole process was just miserable. Clicking through hundreds of samples in a spreadsheet, copy pasting labels, losing track of where I left off. Every tool I found was either enterprise-priced or required setting up three different services just to run. So I built my own thing over a weekend. Ugly UI, barely functional, but it let me label stuff without wanting to throw my laptop out the window. Showed it to two coworkers on Monday and they both started using it immediately. Didnt even ask what it was called. That was about a year and a half ago. Kept hacking on it nights and weekends, added collaborative labeling, version tracking for datasets, some basic auto-suggestions using embeddings. Nothing groundbreaking on its own but having it all in one place apparently matters a lot to people. Put it on GitHub, downloads trickled in, now theres roughly a couple thousand monthly users and I still have my day job. Still labeling on Tuesday nights though.
