View WriterboxWhy buy once?
Software companies turned ownership into rent. A useful tool should not become another monthly bill just because it runs on a computer.
Pay once and keep using the version you bought. Your work stays on your machine in formats that remain useful to you.
We build small tools with a point of view. They will not suit everyone, and they do not need to.
