Is Office PowerPoint Editor free?

The editor itself is completely free. AI edits come with a free sponsored daily allowance for every visitor; beyond that, AI usage is billed per request through SkillSafe credits at cost-based prices, typically around a cent per edit.

Is my PowerPoint file uploaded to a server?

No. The .pptx file is opened, edited, and saved entirely in your browser. Only the slide content you send to the AI assistant (the text of your slides plus your instruction) is transmitted to the AI model to compute the edit.

Can it edit an existing .pptx file from Microsoft PowerPoint?

Yes. Open any .pptx: the app edits slide text, shapes, and tables while keeping the deck's theme, masters, layouts, animations, media, and every untouched slide byte-for-byte intact when you download the edited copy.

Which AI models can I use?

GPT-5.6 Terra is the default. You can switch per request to other models including GPT-5.6 Sol and Luna, GPT-5.1, Claude Sonnet 5, Claude Opus 4.8, Claude Haiku 4.5, and Gemma 4.

Does the AI rewrite my whole deck?

No. The assistant returns targeted operations — change this shape's text, add a slide here, move that slide — and the app applies only those. Slides you didn't ask about are never touched. Every AI edit is one undoable step.

Do I need an account?

No account is needed to edit presentations or to try the AI within the free daily allowance. Sign in with SkillSafe to use the AI beyond the free allowance with your own credit balance.

Edit PowerPoint decks by chatting with an AI

Office PowerPoint Editor is a free, PowerPoint-style .pptx editor in your browser with an AI assistant docked on the right. Click into slides and type — or tell the assistant what you want, and watch the deck update on a live canvas. Your file never leaves your browser.

Start editing — it's free

Quick start

Open or create. Drag a .pptx onto the page, use File > Open, or start a new blank deck — the assistant can draft the slides for you.
Ask the assistant. Describe an edit in the chat panel — the AI reads the deck, makes the change, and the slides update instantly. Every AI edit is one Undo step.
Download. File > Download a copy gives you a real .pptx that opens in Microsoft PowerPoint, Google Slides, or Keynote — with your deck's theme and animations intact.

What the AI assistant can do

Draft a deck from scratch

Give it a topic and get a complete presentation — title slide, agenda, content slides with bullets.

"Draft a 5-slide pitch deck for a coffee subscription startup"
"Create a project kickoff deck: goals, timeline, team, risks"
"Make a 3-slide summary of the attached agenda"

Rewrite & retitle

Tightens wording, fixes typos, and rewrites titles — only on the slides you mention.

"Tighten the wording on every slide"
"Retitle slide 3 to something punchier"
"Make the tone more formal" / "friendlier"

Restructure & reorder

Adds, deletes, merges, and moves slides; turns walls of text into clean bullets.

"Reorder the slides into a clearer story"
"Split the roadmap slide into one slide per quarter"
"Add a Risks slide after the timeline"

Format & layout

Colors, sizes, bold/italic, alignment, shape fills, and repositioning — in points, like PowerPoint.

"Make all slide titles dark blue and bold"
"Center the title on the closing slide"
"Give the highlights box a light yellow fill"

Tables

Edits existing slide tables cell by cell — update numbers, add rows, fix labels.

"Update the pricing table: Pro is now $29"
"Add a row for EMEA to the regions table"
"Fix the typos in the comparison table"

Ask about the deck

Questions get answers in chat — the slides stay untouched.

"Summarize this deck in three sentences"
"Which slides mention pricing?"
"What's missing from this investor pitch?"

What a conversation looks like

Draft a 4-slide kickoff deck for Project Phoenix.

I drafted four slides: a title slide, goals, timeline, and next steps.

Presentation updated

Add a Risks slide before next steps, and bold the dates on the timeline.

Done — Risks is now slide 4 and the timeline dates are bold.

Presentation updated

What would you improve before I present it?

Consider adding an owners table on the next-steps slide and a one-line ask on the title slide; the flow otherwise reads well.

Project Phoenix — Kickoff

Goals

• Modernize the billing platform • Cut invoice latency in half

Timeline

• Discovery — Aug 15 • Beta — Sep 30 • Launch — Nov 1

Risks

• Legacy data quality • Vendor lead times

Next steps

• Confirm owners • Schedule weekly review

Tips for good results

Refer to slides by number. "Rewrite slide 3's bullets" beats "fix the middle part". The slide counter is at the top right of the ribbon.
Chain edits. The assistant remembers the conversation, so "now make it shorter" works as a follow-up.
Mix manual and AI editing. Double-click any text box to edit it directly, drag shapes to move them; the assistant always works on the latest state.
Use Undo freely. Every AI edit is one step in the app's undo history (Ctrl+Z).
Switch models for the job. The dropdown in the chat header offers GPT-5.6 Terra (default), Claude, and cheaper models; the estimate under the input shows the reserved cost before you send.

Frequently asked questions

Is it free?: The editor is completely free. AI edits include a free sponsored daily allowance for every visitor; beyond that, AI usage is billed per request through SkillSafe credits — typically around a cent per edit, shown before you send.
Is my file uploaded anywhere?: No. Opening, editing, and saving happen entirely in your browser. Only the slide content you send to the assistant, plus your instruction, goes to the AI model.
Can it edit my existing PowerPoint files?: Yes — open any .pptx. The app edits slide text, shapes, and tables while preserving the deck's theme, masters, layouts, animations, media, and every slide you didn't touch byte-for-byte through download.
Does the AI overwrite my whole deck?: No — the assistant sends back targeted operations (set this text, add a slide here, move that one), and the app applies only those as a single undoable step. Unmentioned slides are never modified.
Do I need an account?: Not to edit, and not for the free AI allowance. Sign in with SkillSafe when you want to use the AI beyond the daily free preview.
What is not supported yet?: Charts, SmartArt, animations, and speaker notes are preserved in opened files but can't be edited in the app yet. The slide canvas is a faithful preview, not a pixel-perfect PowerPoint render — complex effects show simplified.
