Plus AI Presentation Agent API

Generate presentations with a single API call

Send a prompt and the Presentation Agent plans, writes, and designs a finished deck — returned as native PowerPoint, PDF, and a thumbnail. Build deck generation right into your product, pipeline, or workflow.

3 outputs PPTX, PDF, and thumbnail every run
Webhooks Or poll — your call
Edit or create Start from a prompt or your own deck

Generate from a prompt

Describe the deck you want — say, a 10-slide product overview — and the agent plans, writes, and designs every slide into a native .pptx.
Edit an existing deck

Pass a .pptx and the agent revises, extends, or restyles it in place — e.g. refresh last quarter's board deck with this quarter's story, on brand.
Fill templates with data

Attach a spreadsheet and the agent writes your numbers and charts into a template — like a monthly sales review built straight from your CRM export.
Turn documents into slides

Hand the agent a PDF, doc, or call transcript and get a structured deck back — turn a research report into a board-ready readout in one call.
Translate and localize

Generate or convert a deck into any language, so a single source deck ships to every region without a rebuild.
Refresh on a schedule

Re-run the same job every week or month to keep a recurring report current — wire it into a cron and stop rebuilding it by hand.

1

Upload your files

PUT your template and any data or source files (up to 125 MB each) and get back a fileId for each.
2

Create a session

POST a prompt to /agent/sessions — optionally with your template and attachments. You get a sessionId and polling URL right away.
3

Poll or get a webhook

Check the session until its status is DONE, or pass a callbackUrl and let the agent notify you the moment it finishes.
4

Download the results

Grab the finished pptxUrl, pdfUrl, and thumbnailUrl — ready to deliver, store, or embed.

Data-driven decks

Attach a CSV, spreadsheet, or document and the agent writes the numbers, charts, and commentary straight into your template.
A deck for every customer

Loop the API over your rows — one call per customer, region, or rep — to produce a personalized deck for each from the same template.
Scheduled refreshes

Run it on a cron to refresh a weekly report or board deck with the latest figures — hands-free.

Async by default

Kick off a job and get a sessionId instantly. Nothing blocks while the agent works.
Webhooks, not waiting

Pass a callbackUrl and get notified on every state change — HTTPS-only, with SSRF protection built in.
Bring your own content

Attach spreadsheets, documents, and images so the agent grounds each deck in your real data.
Clean REST surface

A versioned /r/v0 API with an OpenAPI 3.1 spec and conventional HTTP status codes.
Any language

Generate or translate presentations in any language — set it per session or let the agent auto-detect.
Org-scoped and metered

Every file and session is scoped to your organization, with clear credit accounting and typed errors.

Real files, no lock-in

Native PowerPoint out, every time

Each session returns a real .pptx you can open and edit in PowerPoint or Google Slides — plus a PDF and a thumbnail. The decks you generate are yours to keep.

Call it from anywhere

It's just REST over HTTPS with a bearer token and an OpenAPI spec — call it from any language or framework.
Automation platforms

Trigger decks from the tools you already use with Zapier, n8n, or Make — no backend required.
MCP and agents

Pair it with the Plus AI MCP server to let your own agents generate slides as a tool.

How do I authenticate?

Every request sends an Authorization: Bearer $PLUSAI_API_KEY header. API access is included on Pro and Team plans — generate a key from your Plus AI account.

Is it synchronous or asynchronous?

Asynchronous. Creating a session returns immediately with a sessionId and a pollingUrl. Poll GET /agent/sessions/{id} until the status is DONE, or pass a callbackUrl to receive a webhook on every state change.

Can I edit an existing presentation?

Yes. Upload a .pptx, pass its pptxFileId when you create the session, and the agent edits that deck in place — revising, extending, restyling, or translating while preserving your layout and branding.

How do I fill a template with data?

Upload your template and your data export (CSV, XLSX, or a document), reference both when you create the session, and the agent writes the figures, charts, and copy into the deck. To produce many personalized decks, call the API once per record.

What comes back, and how big can files be?

Each finished session exposes a pptxUrl, a pdfUrl, and a thumbnailUrl. Files can be up to 125 MB on the way in.

How is usage billed?

Sessions draw from your plan's AI agent credits. If you run out, the API returns a typed 402 INSUFFICIENT_AGENT_CREDITS so you can handle it gracefully.

Is my data isolated?

Every file and session is scoped to your organization. Callback URLs must be public HTTPS endpoints — localhost and private addresses are rejected to prevent SSRF.

Hands down the best AI presentation maker on the market when it comes to Google Slides. I can generate entire presentations from a prompt, or I can turn text into slides.

Everett Sizemore
I'm particularly impressed by the "Remix" feature that reformats existing slides into new layouts. Love this feature Great work👍

Helen Xiong
Plus AI created a great structure and talking points for my presentation . I really like the tips on each slide to help me choose images or expand on a point. This tool is now in my arsenal!

Kat Murray
The integration into Google Slides is seamless. It feels like something that should have been there all along! 5/5 stars overall.

Avik Lee
Excellent tool that saves me a significant amount of time. It creates a presentation that needs only minor editing when used with detailed prompts . Our team loves it for brainstorming and account reps use it for collaborating with clients.

Gwenette Writer Sinclair
It really helped me to structure my outline which was a time and life saver for a presentation which was due. I like the fact that it can be implemented in Google Slides, a tool I'm already using for presentations anyway!

Tobias Scholz
Tried most of the AI slide generators out there for Google Slide & PPT. This one just hands down the best - it just works.

Ritchie Wong
The integration into PowerPoint is what makes this product so helpful . Making plenty of decks on a weekly basis, I turn to Plus AI for powerpoint first.
