Saving registered member responses on page

I have a membership site where we’d like to add questions in the content, with text boxes for users to give answers.

The site is already set up as a membership site, so what I’m wondering is, is it possible for each member to answer questions and have them saved on-page (via ajax – and written to the database) so that upon returning to that page each member will see (and be able to update) their own answers?

I was using the learndash plugin to set this up but saving the answers on the page for each user doesn’t seem possible with that plugin, and that’s the key feature my client wants.

Here is a visual to help clarify what I’m looking for: https://cl.ly/image/2D3p1V1i1B3M

I’m not looking for specific code yet (unless you’ve got something handy :), just whether or not this is possible and if so how I might go about it, either by specific plugins or custom coding.
