TL;DR
What did u/ThatOnePK use Gemini for?
When a teacher decides to squeeze two lessons into one class, they upload the slides to Gemini and ask it to make them one file with a matching style, instead of copying and restyling slides by hand. In their words: 'Boom, done.' The merged deck is ready without rebuilding or restyling slides by hand.
What they did
They use AI to refine presentations. When they combine a lesson into one day, they upload their existing slides to Gemini and ask it to make them one file with a matching style.
How it went
In their words: 'Boom, done.' The merged deck is ready without rebuilding or restyling slides by hand.
Worth knowing
- It's a short comment, so check every slide afterward: merging can drop speaker notes, images or the order you wanted. Others in the thread warn that AI gets subject facts wrong, so don't let it rewrite content you haven't checked.
- Price check: Google Gemini: free plan; Google AI Plus: US$4.99/month (checked Nov 1, 2026).
Try it yourself
Paste this into a chatbot, then add your own details underneath.
I've uploaded two slide decks for [lesson A] and [lesson B]. Combine them into one deck for a single [50]-minute class. Keep all my content and the order of lesson A then lesson B, use one consistent style (fonts, colors, title layout) based on [deck A], remove duplicate title or agenda slides, and list any slide you changed or cut.
