Nano Banana vs. Gamma: I Tested Both For Midterm Cramming And Still Don’t Have A Clear Winner
Last week I was staring at 17 pages of messy, half-typed lecture notes for my cognitive science midterm, coffee stain on page 4, grocery list scribbled in the margin of page 11, and realized I had no clue how to sort this into something I could actually study from. My roommate, who swears by every new productivity app that drops, said I should try one of those AI slide tools, and mentioned Nano Banana and Gamma as the two big options right now. I had a free afternoon, so I tried both with the same set of notes, just to see which one worked better for learning. Turns out it’s not as simple as one being better than the other.
First I tried Nano Banana. I’d seen people posting their super clean slides on Instagram, all white space, no clutter, so I was expecting something nice. I uploaded all my messy notes, waited 30 seconds, and out popped 28 slides. Each one had barely anything on it. The first slide for the working memory unit just said “Baddeley’s Model” in small black text, with a tiny grey diagram crammed in the bottom corner. I sat there blinking for a minute, like, that’s it? I paid the $12 for a month of pro (the free trial only lets you make three projects, which is useless when you have four midterms) and this is what I get? I went to refill my coffee, came back, and realized it was intentional. The whole point is that you only put the core prompt on the slide, right? You’re supposed to fill in the rest from your own memory.
That actually worked really well for quizzing, I’ll give it that. When I went through the deck, I had to stop at each slide and pull out every detail I could remember before I checked my notes. But it wasn’t all good. Half the time, the prompts were so vague I had no clue what I was supposed to be remembering. One slide just said “Capacity”, and I sat there for five minutes trying to remember if that was the capacity of working memory or the capacity of sensory storage, because Nano Banana had decided that was enough context. Also, when I brought the deck to my study group, everyone got mad at me. One girl leaned over, looked at my screen, and said “Did you even finish making these? There’s nothing here!” I tried to explain the whole minimal active recall thing, and she just rolled her eyes and said I was being pretentious. Awkward.
After that, I decided to run the same exact set of notes through Gamma, just to compare. Gamma spit out 14 slides, way fewer, packed full of stuff. Color-coded callouts for key terms, little boxes that said “common exam question”, a full animated diagram of Baddeley’s model that popped each part out when you clicked it. It even sorted all my messy notes into logical sections that I never would’ve thought of myself, because I’d written them down over three chaotic lectures when I was half asleep. The first thing I noticed, though, was that I spent 22 minutes messing with the formatting. The default teal it picked for the callouts clashed with the diagram, so I moved that, then I resized the text because it felt too big, then I changed the background from the default off-white to a softer cream, and by the time I was done, I’d wasted almost half an hour and hadn’t actually looked at any of the content. That’s the problem with pretty tools, right? You end up caring more about how it looks than what it’s for.
Gamma was way better when I was starting out, though. I missed the first two lectures on working memory because I had COVID back in February, and my notes were just a jumble of things I copied from friends and scraps I got from rewatching 2x speed recordings. Gamma organized all that garbage into something that actually made sense, without me having to do any work. I could read through the whole deck in 10 minutes and get the big picture, which I never would’ve managed with my messy scraps. But when it came time to review for the exam? It was too easy. I just read all the answers off the slide, nodded, and moved on, thinking I knew it. Then last night when I quizzed myself without the slides, I totally blanked on the difference between the phonological loop and the visuo-spatial sketchpad. All the information was right there in front of me, so I never had to pull it out of my own head.
I have ADHD, so that’s a big thing for both. Gamma’s little interactive bits, the animations, the clickable quizzes— I ended up clicking through all of them just for fun, then followed an embedded link Gamma added to a classic memory study paper, then clicked a link in that to a related YouTube video, and 45 minutes later I realized I was watching a TED talk about false memories that wasn’t even on our exam outline. Total waste of time. But Nano Banana is so empty that my mind wanders the other way. I’ll stare at a slide that says “Interference Theory” and 30 seconds later I’m thinking about what I’m getting for dinner, completely forgetting I’m supposed to be studying.
Right now, I’ve been mixing them. I use Gamma first to sort my garbage notes into something that makes sense when I’m starting a new unit, then I export the text and run it through Nano Banana to make a review deck for the week before the exam. It works okay, but it’s extra work, and both of them messed up the spelling of Piaget for my developmental psych deck yesterday and I had to fix every slide manually. I still don’t know which one I like better. I don’t think there’s a one-size-fits-all answer, honestly. If you’re the kind of person who just needs to drill content before a test, and you don’t mind explaining your weird minimal slides to your annoyed study group, Nano Banana’s great. If you’re starting from scratch with messy notes and just need to get a grasp on the material first, Gamma works way better. I’m still gonna keep both subscriptions for this semester, I think, but next semester I’ll probably just go back to making my own messy Google Slides. Old habits die hard, I guess. If you’ve tried both and have a hot take, hit me up— I’m still figuring this out as I go. (Word count approx 1120)
