Need thisssss. Just came here 2022 to see if it's a function

Please build this! It would be so good for client and team feedback!

Please build this feature!! It's a MASSIVE pain point.

great idea!! this will definitely be used in pp presentation or new project introduction

You can use Pastel (https://usepastel.com). Ist works very good with webflow. Your clients can annotate your website drafts without a account or password/login of you share the link to your pastel-canvas.

The productivity gains here could be awesome

I also like the idea of being able to have a conversation within your annotations for when you are sharing work with a client or stakeholder.  It gives annotations a dual use: ux documentation along with communication.  Here's how Adobe handles it in:

UXPin separates out the two use cases, documentation and commenting, which is nice, but I think the two could be handled by the same feature, perhaps with some sort of a toggle or setting:

Adobe's Experience Design CC just implemented this.
