Your Pitch Deck Is Now an App Brief: Base44 Reads PowerPoint

Most people cannot write an app spec. Almost everyone can make a slide deck. That gap is why so many app ideas die between the pitch and the build, and it is exactly the gap Base44 just closed.

On October 28, Base44 added PowerPoint files to the list of things you can attach to your prompt. Attach a deck on the home page, while Base44 is planning your app, or in the AI chat, and Base44 reads it slide by slide and uses it as the reference for what it builds. It joins images, PDFs, spreadsheets, CSVs, Word files, and Markdown, which already worked this way.

What it replaces

The translation tax. You pitch a product for six weeks. The pitch works. Everyone agrees. Then you sit down to build it and you have to reimagine the whole thing as a written spec, and half the detail evaporates on the way. The deck dies in a folder and the app that ships is a game of telephone.

Now the deck is the brief. The structure you already presented, the sections, the flow, the terminology, all of it carries straight into the build because you already did the thinking when you made the slides.

How to use it

1. Click the plus menu in the prompt box and choose Attach files.
2. Upload your deck from your computer, or straight from Google Drive.
3. Send a prompt like "build the client portal this deck describes" and let Base44 plan from it.
4. Answer the clarifying questions it asks, then refine in chat as usual.

If your deck is data-heavy, attach the spreadsheet too. Base44 reads CSV columns and sample rows, so the app builds around your real data shape instead of placeholder fields. And if you have real design, remember you can import from Figma as well; images work as visual reference for a look you want to match.

Five decks that should become apps

1. The startup pitch deck. Feed it in and build the MVP before your next investor conversation. "Here is the deck, and here is the app it describes" is a very good second meeting.
2. The agency proposal deck. Your proposal already contains scope, roles, and screens. Build the client portal with the same sections so the deliverable matches exactly what you pitched.
3. The course or workshop deck. If you teach, your slides are a lesson structure. Turn them into a tool your students log into.
4. The internal process deck. The one HR or ops made for onboarding. It is a spec for an internal tool that nobody has had time to build.
5. The sales deck. Build a lead capture or quiz app that walks a prospect through the same story the deck tells, then hands them to your calendar.

Why it matters for people building income

Two reasons. First, speed: the fastest path from "thing I already pitched" to "thing that exists" is one where nothing gets re-explained. Proposals that turn into working demos the same week win deals that months-long builds lose.

Second, consistency: when the app is built from the deck, the deliverable matches what the client approved. That is the difference between "exactly what we discussed" and a scope conversation nobody enjoys.

Don't overthink the first prompt

The deck does the heavy lifting, so your prompt can be short. Name the audience, name the core action, and let the slides fill in the rest. If the build comes back wrong, you fix it in chat, same as always: one change per message, in plain language.

A walkthrough with a real kind of deck

Say you are a freelancer who pitched a 10-slide deck for a restaurant group: reservations dashboard, staff schedule, weekly inventory pricing, supplier contact book. Attach the deck, send "build the internal portal this deck describes for a 12-person restaurant team, with a manager role and a staff role," and answer the two or three questions it asks about logins and data.

What comes back is an app with those core screens, built in the order your deck already told the story, using the same words your client approved. If slide four promised a weekly pricing view, the app has a weekly pricing view. That is the whole trick: the deck already resolved the arguments, so the build starts from agreement.

Where this fits in the other ways to start

Base44 now has a menu of starts and they all serve a different moment. Have a prompt, use the prompt. Have a Figma file or a screenshot, import the design. Have a site you like, start from a URL. Have a spreadsheet, attach the data. And now: have a deck, attach the deck. In practice you will combine them. The deck gives the outline, the CSV gives the real columns, the screenshot gives the look. The pitch stops being something you present and becomes something you build with.

What the deck import will not do

Worth being straight about this. The deck is a reference, not a contract written in code. Base44 will still ask you clarifying questions, and it should, because decks leave gaps by design. A deck also will not fix a bad idea; if the flow on slide three made no sense, the app will faithfully build nonsense. The tool removes the translation work, not the thinking. Put the thinking in the slides and this feature hands you the shortest path to a real app I have seen yet.

If you have a deck sitting in a folder gathering digital dust, that deck is your next app. Attach it and see what happens: https://base44.pxf.io/c/2084737/2049275/25619?trafcat=base
