How we compare
- BAA without a sales process
- You can put the BAA in place yourself — it is included in standard terms or accepted in account settings — rather than requesting it and waiting for approval.
- Covers a ready-to-use chat app
- The BAA covers an assistant your staff can use directly in a browser or app, not only an API that developers build on.
