Official pages confirm AI features including Notion Agent, Custom Agents, Enterprise Search, AI Meeting Notes, Research Mode, AI writing, translation, file/image analysis, and database creation. By default, Notion and its AI subprocessors do not use Customer Data to train models; subprocessors are contractually prohibited from doing so. Some data-retaining LLM features may be enabled by workspace administrators. Deleted pages/workspaces can be restored for 30 days and are then deleted, including AI-generated data and embeddings. Notion states that it does not claim ownership of inputs or outputs; both are treated as Customer Data. Outputs may not be unique. Supplementary terms were last updated July 27, 2026.
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.

- Slack's AI Principles page says AI features are included in paid plans, while the current pricing page labels the Free plan as having Basic AI. The exact production availability and limits of Free-plan AI could not be reconciled from the official pages.
- Slack does not publish a single numeric usage allowance for all AI features; some capabilities state that plan limits apply.
- No explicit, AI-output-specific ownership statement was located in the checked official Slack sources.
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.
