I am looking for something that allows two or more people to collaborate on ideas. Ideally, something that doesn't require a signup. Something where you can easily share a link with new people. I am not looking for a full kitchen sink, just basic drawing features. Maybe with some pre-defined shapes like a box, circle, and triangles. Thanks!
- RealtimeBoard 2.0 can also be a good fit: simple as Sketch, but collaborative as Google Docs. Check it out here at Product Hunt! I talked to many Designers using this tool and what they really like 😍 is that it's incredibly simple to share and dicuss your work with clients💰 and developers🔧, because boards can be commented and viewed without signup🎉. Although for editing purposes personal account is required.I also stand by Realtimeboard. Great for visualizing just about anything, collaborating with your team, knowledge sharing.RealTimeBoard is incredibly polished, there is a very high level of maturity, everything seems to just work. It's fast and versatile and full of neat features like the ability to copy and paste a bunch of spreadsheet cells to get as many stickies on the virtual whiteboard in one stroke.
- One person would need a Google account, but you could set up a Google Drawing which has the simple features you wanted.
- 1Great for a simple free Online Whiteboard experience, but also includes incredibly rich feature set. You can collaborate from the Online Whiteboard to their whiteboard apps as well. The free version has some limits on exported recording times and projects saved, but still allows for quite a lot.
