Restack

Restack is the deliverable engine for consulting and PE teams. One AI agent that works inside your live PowerPoint, Excel, and Word files, on your firm's templates, with every figure cited. The same analyst works across all three on one account and carries the work between them in a single chat.

One agent across PowerPoint, Excel, and Word:

• PowerPoint: research a topic, build and redesign slides, create charts, and quality-check the deck against your template
• Excel: build 3-statement models and DCFs, write formulas, clean and analyze data, and create native charts and pivots
• Word: draft memos and reports, redline agreements with tracked changes, summarize long documents, and address comments

Carries work between your files: ask once and Restack hands a table from your Excel model onto a slide, or a summary from a Word memo into the deck, with no copy-paste and no rebuild.

Built for work you can trust: every figure keeps its source citation, the AI writes straight into your live file on your firm's template, and your content stays in your environment and is never used to train models. All AI-generated operations run in a locked-down sandbox.

How it works: open the Restack add-in from the Home ribbon in PowerPoint, Excel, or Word, sign in with Microsoft, and chat in plain English. It reads your file, does the work, and shows you the result. Works on Windows, Mac, and the web.

Subscription required after sign-in, with one shared credit pool across all three. Pricing at re-stack.com/pricing; support at re-stack.com/support.
