Try the generator.
On the left is the copy template, on the right the slides. The format on the left is the real one: lines with TITEL (title), TEXT, GRAFIK (graphic) and NOTIZEN (notes), one block per slide.
The text file is the only source. If a sentence changes, the generator runs again and the slides are correct again.
The graphics are drawn shapes, not images. In real use, they are native objects in the PowerPoint file, so the creative team can move them themselves.
This is a demo. Client, industry and slide content are made up. This demo does not build a file. It draws the slides in the browser.
Things to try: Change a sentence in the copy template and rebuild the slides.
The interface of this demo is in German.
Generator, Beispielvorlage
Kopiervorlage
folien_kopiervorlage.txt
Derselbe Schalter steht im Werkzeug: ohne ihn baut es die Kernfolien, mit --alle das ganze Kapitel. Kernfolien sind die, die in der Kopfzeile (Kern) tragen.
Die Grafiken kommen aus dem Teil GRAFIK. Erlaubt sind zeitachse, zweispalter und stufen. Steht dort etwas anderes oder nichts, bleibt die Folie eine Textfolie.
Gebaute Folien
noch nicht gebaut
Auf «Folien bauen» drücken. Der Generator liest den Text links und setzt die Folien daraus zusammen.
Ohne Namen, mit erfundenem Inhalt. Auftraggeber, Branche und Folieninhalte bleiben ungenannt. Diese Demo baut keine Datei: sie zeichnet die Folien im Browser. Im Betrieb entsteht an dieser Stelle eine PowerPoint-Datei, in der jede Linie, jeder Punkt und jede Fläche ein echtes Objekt ist. Das ist der ganze Grund für den Aufwand: Die Kreation soll die Folie anfassen können, ohne zu mir zurück zu müssen.
How the generator works
- 1
- text file as the only source for titles, text and notes
- 9
- slides, either four core slides or the whole chapter
- 0
- pasted-in images. Every graphic is a native shape
- Read The generator reads titles, text and notes word for word from the copy template.
- Build Lines, dots, areas, pills and connectors are created as real objects in the document.
- Hand over After that, the creative team moves things themselves, in their own tool, without coming back to me.
Anonymised. Client, industry and slide content are not named. What you see is how it is built, not the slide deck.
The problem
Several people work on a pitch. The text moves back and forth between the editorial, creative and account teams. At the end, someone turns it into slides. If a sentence changes after that, there are two versions that drift apart.
What the tool does
It reads a text file with titles, text and notes and builds the slides from it. The text file is the only source. If a sentence changes, the generator runs again and the slides are correct again.
The decision that makes the difference
The graphics are native shapes, not images. Lines, dots, areas, connectors and text boxes are real objects in the document.
The reason: an agency that receives a deck wants to be able to work on it. A pasted-in image is a dead end. With native shapes, the creative team moves a line themselves, in their own tool, without me.
What was awkward about it
Fonts are not embedded. On someone else’s computer the deck looks different, and you only notice in the meeting. That belongs in the handover, not in a footnote.
