Always have some type of demo without requiring a login/signup. You lose out on so many people like me that just immediately close as soon as I find out that I can't see what it is without signing up.
That's a very good point. I've just put up some screenshots on the landing page - it's not a demo to be fair, but at least you can see what using it might look like!
I can't read that text ... make it at least so if i click them, they expand to full mode ...
You could record yourself with Loom or OBS and record a quick video you using it -- have that either as a video / GIF -- typically either one big one or one per feature... Just some ideas
