Right now I'm purely solving a personal pain, so I'm just offering it for free because I have to publish anyway and I kinda enjoy the process. As soon as there are enough requests coming in for features that I personally don't use, like syncing, appearance (color, fonts) customization, prompt questions etc. I'm going to experiment with a freemium model to make this more sustainable. This is also why I haven't open sourced it yet, because I want to leave room for experiment and make this sustainable long-term.
