OutlookTriage and reply

Not a chat window bolted onto Office. An agent working in it.

Every result lands as native Office content — editable in Outline View, restyled by your theme, recalculated by your formulas.

PowerPoint

Build a presentation from one prompt

Research, structure, design — slides arrive with hero images, native charts, and cited stats, appended to your open deck.

Real placeholders — Outline View just works
Native charts and tables, not pictures
Iterate: "make slide 4 more visual"

Excel

Turn a workbook into the report

Point it at messy data and get formulas, formatting, charts, and the written narrative — in place.

Reads your sheet's actual structure
Writes formulas and formats ranges directly
Generates the summary alongside the numbers

Word

Draft, summarize, and reply — grounded

Context comes from the document or thread that's open, not from copy-paste. Image generation and analysis included.

Long docs become one-page briefs
Structured, styled documents from one ask
Rewrites and summaries grounded in the open doc

Outlook

Summarize emails, get action items, draft replies

The assistant reads the open message or thread — so summaries, to-dos, and replies all come from what's actually in your inbox.

One-click thread and email summaries
Action items pulled out automatically
Replies drafted from the open thread

Built different where it matters

Editable output

Outline View, themes, and reflow all work — because slides are built from real placeholders.

Native charts & tables

Data-backed PowerPoint charts and Excel objects you can restyle and update.

Agentic research

Searches the web, cites sources, and works in steps — not single-shot generation.

Your choice of depth

High, Balanced, or Low effort per conversation — powered by the latest frontier models.
