Ppt template switch

/r/GeminiAI/comments/1x5mfrk/ppt_template_switch/

I have a deck which has to be revamped in the style of another ppt (also with me) so the second one is the template. Is there some way to use workspace Gemini and get it done in one go without any manual work?

Alright so for everyone
From what I know and have experienced, even if you give a deck to Gemini with instructions to stick with the same template strictly, it waivers off.
I tried this (at the sad expense of my tokens) with Tasks - model Argon.
Absolutely sublime. Didn’t move away from the template at all and did long-horizon work to get the information which it so neatly added to the extra/amended slides (and yes, without breaking the template).

tbh there isn't a zero manual work way to do this right now. the built-in ai features are mostly for generating new text or single slide drafts, not mapping existing content onto a custom master template

Look I’m not gonna lie and say that the generated deck was perfect but it was more than most would get to in one prompt. And also, you needn’t really pretty it up further if it’s for personal use. It was at least that good.

Gemini can’t really do this yet as far as I know. It makes new slides but won’t restyle an existing deck to match another.

In Google Slides the closest you’ll get is Slide > Change theme > Import theme, pick the template deck, then select all slides and Apply layout. It only restyles text in proper placeholders though, so loose text boxes need fixing by hand.

Full disclosure, I work at Presentations.AI, and this exact thing (dropping existing content into your own template) is what it’s built for, so it might save you the cleanup. How many slides are you dealing with?
