Been running client reviews for creative work for a while now. Here's what I've noticed actually eats the time, and it's rarely the creative itself:

Feedback without a pointer gets rebuilt from scratch. "Make it pop" means nothing without someone marking the exact spot. Every vague note costs a full round trip.

Version mix-ups cost more than bad feedback does. Someone comments on V2 after V3 is already out. Now you're reconciling notes across files instead of just fixing the work.

Didn't expect this to be the standout feature, but it is. Clients get a link, open it, comment and approve. No account, no password.
Turns out the biggest adoption blocker for review tools isn't the tool, it's asking a busy client to sign up for one more thing.
For anyone managing client work: how much friction do your clients tolerate before they just go back to email?

Running multi-client creative work, the moment that finally pushed me to build this: a client approved a video over a WhatsApp voice note, then two weeks later swore they never signed off on that version. No record, no paper trail, just my word against theirs.
Proofrr exists so that never happens again every approval lives where the work lives.
Anyone else have a "this is why I built X" moment? Curious what broke for you?
