Detailed Review is a real-time collaboration tool. Users can simultaneously edit and all changes are seen live by users connected to the note/document. It synchronizes everyone’s edit & merges them all in real-time. Multiple people can simultaneously edit the same document, any changes reflect on everyone’s screen instantly.

I tested (Public) with a team of 4 members (collaborators), simultaneously & randomly writing on the pad. There’s a Paid version as well - (Pro).

The most impressive feature was its real-time synchronization capability. I was curious to know the time lag in syncronization i.e. the difference in time of typing the letter & appearing of that letter at the other end. To calculate this we accessed the same note (document) from two systems placed besides each other (so that we can view both the monitor screen). Interestingly, we could see each & every letter typed by other collaborators/members at our screen as if it was being typed from the keyboard attached to the local system. Practically, there was no perceivable lag at all.

We did a similar test with Google Docs - document, in the same environment. But its synchronization ability proved to be slower compared to In Google docs document, chunks of words appeared suddenly after a significant lag of say 12 seconds.
