I don't know, I like it. I think it'll be incredibly tough to sell because you're competing with text editors, which esp. engineers use on a daily basis... When I think about it, things like:

- Organizing text (e.g. source files)

- Ordering text (e.g. based on dates)

- Syncing text to a backup (e.g. gdrive)

- Setting up a reminder (e.g. crontab)

All of the above are kind of core competencies of a lot of engineers. So I think it has to do more, such as drag-and-drop images like Evernote, integrate with Jira/Slack, integrate with Anki (for whatever reason), I don't know...

I like the idea, but personally, I wouldn't buy it because I can do all of the above myself with literally minimal effort. I hope you can make it a more compelling offer. Looks great to me though, I wish you all the success!

Note that maybe the solution is to target different users than engineers. Students wouldn't care about Jira/Slack integration, for example. Then again, students wouldn't pay for this, they get their stuff for free from Microsoft.
