I have a confession. I watch a lot of YouTube tutorials. Python stuff, woodworking odds and ends, random electronics projects. And for years, I'd finish a 40-minute deep dive, feel like I'd absorbed it all, and then two days later I'd be staring at my code editor or my workbench with absolutely nothing in my head. Just a vague sense that I'd seen someone do something similar once.

Honestly, it started to freak me out a bit. Was I just moving my eyes across the screen? Was my brain actually processing anything?

Turns out, probably not. Not in any useful way, at least.

The illusion of understanding

Here's the thing about video content. It's passive. You sit back, someone walks you through something step by step, and it feels like you're following along. But following along isn't the same as learning. It's the difference between watching someone bake a cake and actually making one yourself.

The research (and I'm being vague here because I don't remember exactly who published it) suggests that without some form of active engagement, most of what we consume goes in one ear and out the other within 48 hours. And YouTube, for all its virtues, is basically designed to keep you consuming. One video rolls into the next. There's no natural pause point to stop and think.

So I needed to force one.

What I started doing

I built a habit that sounds almost too simple to work. I keep a text file open (or sometimes a physical notebook if I'm feeling retro) whenever I watch a tutorial. Every time the presenter says something useful, or I have a thought about how I'd do it differently, I pause the video and write it down.

Just a sentence or two. A timestamp if it's a specific step I want to revisit. A note about why I disagree with their approach. Anything that forces me to engage with the material instead of just absorbing it.

And this is where I should mention that I also use a little tool I built called Timestamp Bookmarks for YouTube. It's a browser extension that lets you save multiple timestamps in a video and add labels to each one. So instead of scribbling "minute 12:34 - the bit about error handling" in a notebook, I can just hit Alt+S and type a quick note. It can sync across devices, which is handy because I switch between my desktop and laptop a lot.

Is it perfect? No. The free tier is fine for most of what I do, and the Pro version is £12 a year if you want export features. But honestly, even just using the keyboard shortcut to drop a timestamp forces me to pay attention in a way I wasn't before.

What changed (and what didn't)

After a few weeks of this, I noticed something. I could actually remember what I'd watched. Not every detail, but the core concepts. If someone asked me about a specific tutorial I watched three weeks ago, I could say more than just "yeah, it was good."

But here's the pessimistic bit. It's not a magic fix. I still forget plenty. I still watch some videos and realise halfway through that I've already seen them and retained precisely nothing. The habit only works if you actually do it, and there are days when I can't be bothered to hit pause and write a note.

And sometimes the act of writing distracts me from the flow of the video. I'll miss a crucial step because I was typing up a note about something that happened thirty seconds ago. It's a trade-off.

The real takeaway

I think the specific tool matters less than the act of pausing and writing. Whether it's a notebook, a text file, or Timestamp Bookmarks for YouTube, the point is to break the passive consumption loop. To force yourself to engage.

If you've been watching tutorials and feeling like nothing sticks, try it. Just pick one method and stick with it for a couple of weeks. You might be surprised at how much more you actually take in.

Or you might not. Everyone's brain works differently. But it's worth a shot.
