Abacus AI in PowerPoint: a finished travel-deck title slide beside the task pane generating hero imagery for the presentation

PPowerPoint

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"

Abacus AI in Excel: a revenue table with a generated stacked column chart, the task pane explaining the three chart views it added

XExcel

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

Abacus AI in Word: a structured multi-section document written by the assistant, with the task pane showing its progress

WWord

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
Email triage and drafted replies in Outlook

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.
