Most teams find out their annotation platform cannot handle the real workload six months after signing the contract.
Not during the demo. After the rubric changed mid-project and label history vanished. After the CISO asked for a data flow diagram and got a compliance badge back.
Picking a GenAI annotation platform is not a software purchase. It decides whether your model ships, scales, or clears compliance review.
When you get to final vendor comparison, stop scoring on adjectives. Score on specifics:
๐ ๐๐๐ญ๐ ๐ซ๐๐ฌ๐ข๐๐๐ง๐๐ฒ โ self-hosted in client cloud, zero vendor retention
๐ ๐๐๐ ๐ซ๐๐ฉ๐จ๐ซ๐ญ๐ข๐ง๐ โ cohort-level Krippendorff's alpha, refreshed weekly

Vendors who hesitate on any of these are telling you where the platform is weakest.
