Slides for LLMs. AI-powered presentations.Slates is built from scratch for agents, not adapted from human-first tools. JSON-native: Presentations are structured data. Grid layouts: No pixel coordinates. Agents pick templates and fill content — the grid handles design. MCP-first: One connection and any agent can create presentations programmatically. Existing tools are retrofitted for programmatic access. Slates assumes the agent is the primary user from day one.
