Microsoft 365 Copilot leads 10 AI agents for slide decks

AINOW's comparison rests on a practical split it draws between chat-style writing and agents that finish the slide itself: agents can carry a document from information gathering through an outline to an editable PowerPoint file. Microsoft 365 Copilot made its agent features generally available in Word, Excel and PowerPoint on 2026年4月22日, while Claude for PowerPoint became generally available on 2026年5月7日 for Pro, Max, Team and Enterprise plans. Gemini followed with presentation generation in Canvas in 2025年10月, and Gemini Notebook, renamed from NotebookLM in 2026年7月, generates decks only from uploaded material.

The selection criteria AINOW proposes map onto specific weaknesses. Image-based slides cannot be edited, so a single typo forces regeneration; AI agents can mix in fabricated figures, which is why the guide points to sourced tools like Skywork and to material-grounded Gemini Notebook. Template fit is another divide: Copilot reads the slide master inside PowerPoint, whereas ナレッジワーク資料作成エージェント is built per company and its pricing is not public. For companies on Microsoft 365 or Google Workspace, AINOW suggests starting with the agent tied to those suites.

What the reader gets out of this depends on how the draft-and-review workflow is set up. The guide's five-step process — state purpose, reader and conclusion, hand over material and template, agree on an outline, generate, then verify figures and sources — treats the outline check and fact check as the steps that keep revision time down. Whether a team gains net time is likely to hinge on whether its chosen tool exports editable files and whether staff actually run the final verification, since the guide notes submitted documents are judged on the person and company behind them, not the AI.
