Fair knowledge of QnA Maker service


There comes a scenario where we need to upgrade our QnA Maker service associated with QnA Maker knowledgebase. QnA Maker service provides to tiers as part of management pricing tiers.

  • Free Tier – Allows up to three managed documents with the size of 1 MB each.
  • Standard Tier – Allows unlimited managed documents.

We cannot add more than three documents to knowledgebase with associated QnA Maker as a free pricing tier.

In such cases, we need to go for upgrading our QnA Maker service.
