Presentation editor · any format in, any format out
Every deck, whatever it
arrived as.
pptGPT opens PowerPoint, PDF, Figma and Illustrator files as editable objects, keeps each piece of work in a project together with the material behind it, and puts an AI assistant that works on the real slides at the centre of the editor. When you are done it hands back a .pptx, a screen deck or a print-ready PDF.
Free to start · nothing to install · your files open in the browser
.pptx, PDF, .fig, .ai and .idml open as shapes and text, not pictures — and go back out the same way.
Decks live next to the reports, spreadsheets, earlier decks and images they are built from, with roles for the people involved.
An assistant that reads the project, plans the story and edits the actual slide objects — then checks its own layout.
16:9 for the screen, A4 to A0 for the press, or any custom size — with ICC colour and PDF/X-4 when it matters.
Format-agnostic
Built around the file you were handed, not the one we would prefer.
Most browser editors treat other people's formats as something to convert once and forget. pptGPT reads them as objects — a shape stays a shape, a paragraph stays a paragraph — so the deck can be edited, handed back in the format it came from, or moved to another one.
Comes in
Opens as editable objects.
- .pptx
- Parsed the way PowerPoint parses it: masters, layouts, placeholder inheritance, theme colours and fonts, preset and freeform geometry, autofit and line spacing.
- Paste from PowerPoint
- Copy slides in PowerPoint for the web and paste them in. Shapes arrive as shapes, still bound to the master they were designed on.
- Open a PDF and make its pages editable — text becomes text boxes, vector art becomes paths, pictures land in the asset library.
- .fig
- Figma files come across with frames, auto layout, text styles and colour styles as variables.
- .ai and .idml
- Illustrator artwork opens as vector shapes; InDesign documents come in through IDML with their text flow.
- Word, Markdown, spreadsheets, JSON
- Documents open in a markdown editor. Spreadsheets and data files become project material the assistant can read and quote.
Goes out
Written, not flattened.
- .pptx
- Written back as OOXML with masters, theme references, geometry and text structure intact — a colleague keeps editing in PowerPoint. One button opens the deck in the PowerPoint app on your machine.
- PDF for the screen
- Vector output of every slide, with the fonts embedded.
- PDF/X-4 for print
- ICC colour management, real CMYK separation, output intent and total-ink checks, with a soft proof on the canvas before anything goes to press.
- .ai
- Illustrator-compatible export when the artwork has to continue in Adobe's tools.
What exactly survives a PowerPoint round trip is listed further down, item by item, including the honest note about what OOXML cannot express.
Project-based
The deck lives with the work behind it.
A presentation is rarely the source of anything. It is made from a report, last quarter's deck, a spreadsheet and a folder of photos. In pptGPT those live in one project, and the assistant in every deck of the project can read all of them.
Pictures inside uploaded decks, PDFs and Word files are pulled into the project's image library automatically, so a portrait in the CV you uploaded is one search away from the slide.
A project holds
- The decks you are making
- Earlier decks to borrow from
- Reports and briefs as PDF or Word
- Spreadsheets and data files
- Photos, logos and generated images
Who may do what
- Owner everything, including deleting the project and choosing owners
- Admin manages members, renames, describes and removes content
- Collaborator adds and edits decks and material
- Viewer opens decks read-only and reads the material
Or open a project to everyone in your organization with one role. Images extracted from a project's files stay visible to its members only.
AI native
An assistant that works on the slide, not on a picture of it.
The assistant has the same tools you do: it reads the deck, the template and the project, and edits shapes, text and layouts directly. Nothing is regenerated from scratch, and what it makes is a normal deck you keep editing.
Reads the project
Lists the material, reads decks as slide text, PDFs page by page and spreadsheets as rows, and quotes figures from them instead of inventing numbers. When something only you know is missing, it asks once.
Plans before it draws
Writes a brief and a storyline, decides what each slide must say, then builds the slide with speaker notes — its notes stay notes, and never end up on the slide.
Edits the real objects
Duplicates the deck's own elements, fills template layouts, sets text and styles, arranges auto-layout frames, and adds runs of the right length instead of squeezing five steps into four boxes.
Checks its own work
After every layout change it gets a render and an objective check for overflowing text, overlaps and a muddled visual hierarchy, and fixes the geometry before it reports back.
And the parts nobody enjoys
- Generates images with GPT Image or Gemini into the project's library, sized for the box they fill
- Finds the right library image by meaning, not filename, and places logos and photos without distorting them
- Chooses fonts the template defines, or ones actually available on your device — never a font that would break
- Translates a whole deck in place, keeping every run's styling and the original alongside
- Decides where long words may break, once per word, so justified text sets cleanly
Digital and print
The same slide on a screen, a poster or a press sheet.
A deck is not always a deck. The page size is a document setting, so the same objects and the same auto layout serve a 16:9 presentation, an A4 one-pager or an A0 poster, and the export follows the medium.
Present straight from the browser, share a view or edit link, hand back a .pptx, or export PDF/X-4 with the output intent the printer asked for.
For the screen
- PowerPoint Widescreen 16:9 and Standard 4:3
- Full HD 1920 × 1080
- Social square and story
- Any custom size in pixels
For print
- A0 to A6 and B0 to B6
- US Letter and Tabloid
- Any custom size in millimetres, portrait or landscape
- ICC profiles, CMYK separation, soft proof and total-ink checks
File fidelity
What survives the round trip.
Open a deck, change one headline, save it back, and the rest of the file should be where you left it. That is a boring promise and a surprisingly hard one, so here is the specific version of it.
Where a design uses something OOXML genuinely cannot express — a blend mode PowerPoint has no word for, say — the editor tells you before it exports, and rasterises only the shape in question rather than the slide.
Structure
- Slide masters
- Slide layouts
- Placeholder inheritance
- Speaker notes
- Comments
Theme
- Colour scheme
- Font scheme (major / minor)
- Named colour variables
- Named font variables
Geometry
- Preset shapes + adjust handles
- Freeform paths
- Vector masks
- Line dash patterns
- Arrowheads and joins
Text
- Paragraph and run structure
- Line spacing and paragraph spacing
- Blank paragraphs
- Autofit / font scale
- Body insets and anchoring
Bring the worst deck you own. And the report it came from.
Start a project, drop in the deck with the inherited master, the PDF nobody has read since March and last year's numbers, and ask the assistant for the update — the free tier is enough to find out.
