Plain is an AI-native office suite that turns chats, Markdown, files, and data into polished decks, documents, and dashboards. Unlike traditional office tools, the source stays structured and the deliverable is a live link that remains current as you edit. When a file is required, export to PPTX, DOCX, XLSX, or PDF. Use Plain on the web or from Claude Code, Cursor, and Codex through MCP/CLI；
