Admin Console: Review Work, perform "trusted" tasks, worker insights: avg | |
completion time, # of workers,; remove bad performing workers from specific | |
task groups | |
getting started, no charge for now: get an api key (houdini/sign-up), tunnlr | |
pricing example, $20/200 images/month, $99/1500 images | |
