Claude for PowerPoint: What the Add-In Can Build
Claude for PowerPoint is an add-in that builds and edits slides inside PowerPoint, using your existing template rather than a generic theme. The capability that separates it from a deck generator is narrower than it sounds: it can rewrite one slide without regenerating the whole deck, which is the difference between an AI you use once and one you keep using through five rounds of edits.
It’s part of the same Claude for Microsoft 365 add-in as Claude for Excel, installed from the Microsoft Marketplace, and available on Pro, Max, Team, and Enterprise.
What it builds
- Full deck structure from a description. Say what the presentation needs to accomplish and get an outline rendered as slides.
- Slides on your existing template. It works within the layouts and styling already in the file instead of imposing its own.
- Single-slide edits. Change slide 14 and slides 1 through 13 stay exactly as they were.
- Bullets converted to visuals. Text turned into diagrams, and into native PowerPoint charts rather than pasted images.
- Context from connected tools. Whatever connectors your Claude account has configured can feed the content.
- Formatting preserved through iteration. Repeated revisions don’t gradually degrade the design.
Native charts are worth calling out. A chart Claude creates is a real PowerPoint chart object, so you can edit its data, restyle it, and animate it like any other. An image of a chart would be useless the moment a number changed.
What it won’t do
| Limit | What it means |
|---|---|
| Not on PowerPoint 2016 or 2019 | Older desktop installs can’t run the add-in |
| Not on iPad or Android | Desktop and supported web only |
| Instructions don’t carry from Excel | Custom instructions are per-app |
| Prompt injection from untrusted files | A deck from an unknown source can carry instructions aimed at Claude |
| Data retention doesn’t inherit org settings | Custom retention configured elsewhere doesn’t automatically apply |
| Audit telemetry is Enterprise-only | SIEM integration requires the Enterprise plan |
Anthropic also says plainly that it isn’t for final client deliverables without human review, that presentations containing sensitive or regulated data need proper controls, and that it can’t replace human judgment on design and narrative. The narrative point is the honest one. Claude will produce a competent structure and cannot tell you whether the argument lands.
Building a deck from a spreadsheet
The common request is a deck built from analysis that lives in Excel. That works, through a setting Anthropic calls Office agents, which lets one conversation span both add-ins so you don’t re-explain the analysis or copy values between windows.
On Pro and Max it’s on by default. On Team and Enterprise an owner turns it on at Organization settings, then each member enables “Let Claude work across files” in the add-in. Two constraints apply: Claude only reaches files that are already open, and cross-app chat history isn’t saved between sessions. Claude Office Agents has the full picture.
For decks aimed at communicating an idea rather than reporting numbers, Claude Design is the other Anthropic product in this space. It generates decks from a description and exports PPTX, without needing PowerPoint open.
The deck gets built, then waits
Claude for PowerPoint compresses the hours between “we need a deck” and “here’s a draft.” Everything after the draft is untouched: sending it, tracking whether the client opened it, updating it when the underlying numbers move, following up when nobody replies.
These assistants can run on a schedule now — ChatGPT Scheduled Tasks and Claude Cowork both do unattended work on a timer. What none of them do is fire on an event: nothing starts because a record changed, a message landed, or a deadline passed. The schedule is the trigger, and the gap between "every hour" and "the moment it happens" is where the work falls through.
Carly is built for that half. It runs on triggers and schedules across roughly 260 native integrations, plus anything with a public API through your own key on the integrations dashboard:
- Every Monday at 7am, refresh the reporting numbers from your CRM and analytics and send the summary
- When a deck is shared to a client folder, log it against the account and schedule the follow-up
- When a proposal goes unanswered for five days, draft the nudge and flag it for the owner
Carly is free for Zapier-style workflows, with AI agents from $35/month.
FAQ
Is Claude for PowerPoint free? No. It needs a paid Claude plan: Pro, Max, Team, or Enterprise. It installs as part of the Claude for Microsoft 365 add-in from the Microsoft Marketplace.
Can Claude edit one slide without rebuilding the deck? Yes, and it’s the main reason the add-in survives real editing cycles. Targeted slide edits leave the rest of the file untouched and preserve formatting across repeated revisions.
Does it use my company template? Yes. It builds within the layouts and styling already in the presentation rather than applying a generic theme.
Which PowerPoint versions are supported? Not 2016 or 2019, and not iPad or Android.
Can it pull data from Excel into slides? Yes, with Office agents enabled. Both files must be open, because Claude cannot open, close, or switch files on its own.
Can it make charts I can edit? Yes. It generates native PowerPoint charts, so the data and styling stay editable, rather than inserting a picture of a chart.

"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
