SAN FRANCISCO (Reuters) -Microsoft ( MSFT ) has combined the separate marketplaces for its artificial intelligence tools aimed at businesses into one offering, it said on Thursday.

It previously offered tools for software developers, who use its Azure cloud computing service, on one marketplace and applications and so-called "agents" - AI tools designed to carry out tasks on behalf of human users within applications - on another.

Starting on Thursday in the United States and rolling out globally in the coming weeks and months, Microsoft ( MSFT ) will be moving them all onto its new "Microsoft Marketplace" aimed at corporate technology buyers. 

Apps and services on the marketplace will be streamlined for easy use with existing Microsoft ( MSFT ) products. And Microsoft ( MSFT ) customers will pay for them via their existing Microsoft ( MSFT ) billing relationships, Alysa Taylor, the company's chief marketing officer for commercial cloud and AI, told Reuters.

Unlike consumer app stores, Microsoft ( MSFT ) will not charge a commission on apps available on the marketplace.

Instead, Microsoft ( MSFT ) charges a publishing fee to apps listed there, and then makes money from whatever Microsoft ( MSFT ) cloud services developers selling on the marketplace may be using, Taylor said. 

Apps on the store must pass a security and compliance review from Microsoft ( MSFT ) to ensure that businesses using them will be able to control what corporate data they access, she added.

"There's a gate to get into the marketplace," Taylor said.
