Hey, this is strikingly similar to a tool I built a number of years ago, and used personally for some time. All the way down to the color scheme and the heatmap style calendar. Great job on shipping - something I never did! My only real immediate feedback is that your initial editor gets drowned out in the monochrome color scheme among everything else on the page. I had to go hunting for it. Otherwise the "just start, then create an account" is a great workflow that I've used successfully in other places. However, most users don't understand in-browser saving versus saving on your server. I would recommend making a stronger push toward signing up for an account in order to save. In my app I had a feature built to "ramp up" your writing. This was great because I didn't have to immediately start out writing say, 500 words a day - I could start small with 50. Once I hit that the counter goes up and the next day I have to write 60, then 70, and son on. It doesn't have to be linear, but being able to start small and increase my progress each day was much less intimidating.
