Shortlist

Why these names

• Microsoft Teams — human 73, agent 82. Microsoft Teams is chat, meetings, and files for organizations already paying for Microsoft 365. The human UI is heavier than Slack.

• Discord — human 85, agent 88. Discord is the community chat stack: voice, text, stages, forum channels, and a bot ecosystem that predates the LLM wave. Humans hang out. Agents are first-class via the Gateway and REST bot APIs — among the most-used agent surfaces in this catalog. It is not Slack for. Compare with Slack
