The best app for keeping a secure diary

Needs a lot of work

Solid diary’s AI is asking me to share some information - but there is no way of communicating with it other than making an entry then hitting the AI button.

It asks me to tell it things but there is no way to do it

If I can’t reply - why does it ask me too?

It suggests using browser tools, to copy text but there is no web based version of the app.

It suggests disabling Mood analysis, but I can’t find a way to do it.

It’s training on itself seems to be non existant.

I love this company

I love all the app from this company but the journal is amazing! I am not a writer but I find it so easy to use and I can express myself in a way that feels natural! Days when I am having a tough time I will write as many enteries as I need! I love how simple and easy it is to use and that I can add pictures and other things so quickly and easily
