Can people comment from a phone?

Yes. On a phone the toolbar sits at the bottom of the screen, and comments open full screen.

What happens to comments when the design changes?

They stay on the component they were made on, because each component has its own id in the code.

Inviting people needs Starter (up to 5 people), Pro (up to 10) or Team. The people you invite take part free, and need no plan of their own.

Reviewers click any part of the running prototype and comment on it. No screenshots, no long threads asking which button someone meant.

Every comment sits on the part of the page it is about.

1
Invite your reviewers
Type an email and pick Reviewer. They get a link to the prototype and sign in on the Crux button.
2
They click and comment
A reviewer clicks Inspect, then any part of the page, and writes a comment on it. Labels say what kind it is, and @mentions bring the right person in.
3
You hear about it
New comments and replies show in the bell in Crux. Anything you have not opened by the next morning comes in one summary email.
4
Reply where it was said
Every thread stays on its component, on the prototype and in Crux, so the reply is read next to the thing it is about.

The Crux connector adds one toolbar to any prototype.
