Microsoft Copilot vs Slack Ai

Microsoft 365 Copilot Chat is available for work or education without an additional Copilot license and supports metered pay-as-you-go agents. Microsoft 365 Copilot Business is displayed at a promotional $18/user/month, paid yearly, versus a $21 list price. Microsoft 365 Business Standard with Copilot is $23.50/user/month paid yearly, and Business Premium with Copilot is $32/user/month paid yearly. Prices are USD, annual subscriptions that auto-renew, and may vary by market.

This verification is scoped to Microsoft 365 Copilot for business, not every consumer or product-specific service branded Copilot. Microsoft 365 Copilot works in Word, Excel, PowerPoint, Outlook, Teams, Loop, and other Microsoft 365 surfaces; it uses Microsoft Graph data the user is permitted to access and includes Copilot Chat, Copilot Search, agents, and app-specific drafting, summarization, analysis, and meeting capabilities. Prompts, responses, and Microsoft Graph data are not used to train foundation LLMs. Interaction content is stored under the customer's Microsoft 365 contractual commitments, encrypted at rest, manageable through Microsoft Purview, and deletable through Copilot activity history controls. Microsoft does not claim ownership of service output but does not determine whether output is copyright-protected or enforceable. Its Copilot Copyright Commitment can defend qualifying commercial customers against certain copyright claims when required guardrails and content filters were used.

Free: $0. Pro: $7.25/user/month when paid annually or $8.75 when paid monthly. Business+: $15/user/month annually or $18 monthly. Enterprise+ uses sales-based pricing. The pricing page labels Free and Pro as including Basic AI and Business+ as including Advanced AI; the exact feature set depends on plan and admin settings. The page was also displaying a 50%-off-for-three-months promotion for eligible Pro and Business+ purchases.

Official pages list capabilities including Slackbot, conversation and thread summaries, daily recaps, AI search, file summaries, workflow generation, huddle notes, translation, and enterprise search, with availability varying by plan. Slack states that Customer Data never leaves Slack-controlled infrastructure and is never used to train LLMs. Third-party LLMs are hosted within Slack's cloud environment; providers do not have access to Customer Data. AI only uses content the requesting member is authorized to access. Conversation summaries and search answers are ephemeral; recaps are stored for 90 days. Workflow-generated summaries stored in messages or canvases follow the organization's retention settings. Admins can disable or restrict native AI features.
