GitQuiet vs PRFlow
In the tab, not a Chrome side panel.
GitQuiet is in the tab on github.com. PRFlow is a Chromium side panel with its own login.
PRFlow
PRFlow lives at prflow-ext.com (not prflow.dev). It is a Chromium side panel. It asks for a PAT, and it is read-only. Pull requests sit in role buckets.
GitQuiet
GitQuiet uses the GitHub session you already have. No extra login, no PAT. Every pull request you are in, across repositories, filed by next action: Needs You, Waiting, Running, Settled. It writes back through GitHub's own routes. This is not an AI reviewer.
The job looks close: a list of pull requests beside GitHub. The surface is not. PRFlow is a panel Chrome draws next to the page. GitQuiet is the page. Attention Set is a PAT near-miss on the same axis: a whose-turn popup (Needs you / Waiting, no Running), not a fifth URL.
