Edit PowerPoint text online
Drop a .pptx, fix the slide text and speaker notes, download the edited deck. No PowerPoint needed — and when the words are right, Noty can narrate every slide.
Three steps, done
Drop your PPTX
Drag a .pptx onto the page, or click to pick one. Every slide opens as a list of editable fields.
Edit text and notes
Tweak titles, body text, bullets and speaker notes inline. Changed fields are highlighted so you can see what you touched.
Download the .pptx
The edited file downloads. Open it in PowerPoint, Keynote or Google Slides — it looks exactly like the original, just with your changes.
Your deck, with a voice
Narrated PowerPoint
Every slide voiced by an AI voice, timed to auto-advance. Download the .pptx and press play.

Before
A deck with typos and stale numbers
The slides you were sent, the template you borrowed, the speaker notes you never finished.
After
The same .pptx, text fixed
Layout, images, colours and animations untouched. Ready to present — or to hand to Noty to narrate every slide.
The words are fixed. Now give them a voice.
Editing gets the text right. Noty in the Studio chat takes it from there: it rewrites what you ask, voices every slide from its text or speaker notes, and hands back a PowerPoint that plays itself.
What you can edit (and what stays as it was)
The editor is built for the most common job — fixing words — without a heavyweight install. Everything else in the deck is carried through untouched.
Slide titles and body text
Every text paragraph on every slide, including bullet points and list items.
Speaker notes
The notes for every slide, ready for the presenter — or for Noty to read aloud.
Shapes, callouts and tables
Text inside shapes, callouts and table cells is editable too.
Not editable: images and layout
Images, logos, slide layout, positions and sizing stay exactly as they were in the original.
Not editable: styling and motion
Colours, fonts, theme styling, charts, animations and transitions are preserved from the original, not changed here.
Not editable: slide order
Adding, removing or reordering slides needs PowerPoint, Keynote or Google Slides.
Fixing text is one thing. Making the deck speak is another.
PowerPoint Online and Google Slides are full editors. Notevibes fixes the words fast — and then turns the deck into a narrated PowerPoint, an MP3 or a video.

Who edits PPTX online?
You don’t always need a full editor to fix a typo, swap a stat or rewrite a bullet. Here’s who reaches for a lightweight online editor.
Anyone with a deck and no Office licence: you got a .pptx, you need to change two words, and you don’t want to buy PowerPoint to do it. Consultants polishing client decks: quick text tweaks between meetings without firing up a heavy desktop app.
Students adapting templates: use someone else’s slide template and personalise the text without losing the layout. Localisation and translation teams: swap source-language text for translated copy across an entire deck in one sitting — and have Noty voice the translated deck when it’s done.
A note on formatting
When a paragraph has a single style — say, a bullet point all in the same font — your edits keep that style perfectly.
When a paragraph mixes styles — say, half the sentence is bold and half is not — the editor shows a small “mixed” tag next to the field. If you change that paragraph and save, the rewritten text picks up the formatting of the first run only. The rest of the deck stays untouched.
In real-world decks, mixed-formatting paragraphs are uncommon. If you do hit one and care about preserving the split, open the file in PowerPoint after saving and re-apply the bold or colour where needed.
After the edit: a deck that presents itself
Clean text is the best starting point for narration. Once the slides and notes say what you mean, Noty in the Notevibes Studio can voice every slide from its text or speaker notes and hand back a PowerPoint that auto-advances, plus an MP3 of the whole deck.
Pick a natural AI voice or clone your own once and every deck sounds like you presenting. Video export of the narrated deck is coming next.
Edit the words. Then let Noty say them.
Noty narrates every slide in a natural voice — or yours — and hands back a PowerPoint that plays itself, plus the MP3.

Frequently Asked Questions
How do I edit a PPTX file without PowerPoint?
Drop the file into the editor at the top of this page. Every slide becomes a set of editable text fields. Change what you need, download, and your edited .pptx is ready. PowerPoint is not required.
Is the editor really free?
Yes. No account, no sign-up, no caps on how many files you edit.
Are my files uploaded anywhere?
No, the deck is edited and rebuilt in your browser.
Will the layout and design survive?
Yes. The editor only touches text content — slide titles, body text, bullets and speaker notes. Layout, images, colours, theme styling and animations all stay exactly as they were.
What about bold, italic, and coloured text?
If a paragraph has consistent formatting, edits keep it perfectly. If a paragraph mixes formatting (e.g. bold mid-sentence), the editor flags it as “mixed” and saving flattens that paragraph to the first run’s formatting. The rest of the deck is unaffected.
Can I add or remove slides?
Not in this editor — it focuses on text changes. For adding, removing or reordering slides, use PowerPoint, Keynote or Google Slides.
Does it work for old .ppt files?
Only .pptx (PowerPoint 2007 and later). For older .ppt files, open them in PowerPoint, Keynote or Google Slides first and save as .pptx.
Will the file open in PowerPoint and Keynote?
Yes. The editor rewrites only the text portions of the file and leaves the rest untouched, so the result remains a valid .pptx that opens in PowerPoint, Keynote, Google Slides and LibreOffice.
Can Notevibes narrate the deck after I edit it?
Yes. Tell Noty in the Notevibes Studio and it voices every slide from its text or speaker notes, then hands back a narrated .pptx that auto-advances and an MP3 of the whole deck. Pick a natural AI voice or clone your own. Video export is coming with the next update.
