Straight answers, including where another tool is still the better choice.
Review is meant to be the low-friction part. The whole model is built so the person with the opinion can point at the thing and say the thing, without a seat being purchased for them or a tool being learned first.
It works on the live web pages you point it at, because it runs in the browser rather than inside your codebase. Teams typically use it on their own staging and production URLs, and on preview deployments during review.
Threads carry a workflow stage, so a round of feedback can move from raised to in progress to in review without being retyped somewhere else. When a change is needed, the thread itself can be sent to a coding agent with the context attached.
Yes, and plenty of teams should. Pastel keeps doing what it is good at, and Yocoolab handles the part that happens on the running product — pinning feedback to a real element, keeping the discussion attached to it, and handing that context to a coding agent. Yocoolab is a browser extension, so it sits on top of your app without you migrating anything.
No. The app is free, and it stays free — including for everyone you invite to look at or comment on work. Any paid add-on in the future would be a new, optional capability, never a toll on people who just need to see the thing.
Install the browser extension, sign in, and point it at the URL you want feedback on. There is no SDK to embed and no code change to your app, so the first pinned comment usually happens within a couple of minutes.
