How to Use User Sessions to Validate Product Hypotheses

Validating highlight viewer can be one of the most exciting parts of building something new. You have an idea, a hunch that you're on the right track—but how do you know if real people actually feel the same? That’s where user sessions come in.

User sessions let you watch how real people use your product. Think of them like silent movies of people clicking, scrolling, or tapping their way through your app or website. Watching these sessions can show you what users love, what confuses them, and what they completely miss. It’s like being a fly on the wall while someone tries to use what you've built.

For example, say you think adding a search bar at the top of your homepage will make things easier for people. By watching user sessions, you can see if they actually use it, how often, or if they skip right past it. This real-life behavior can either support your idea—or tell you that you need to rethink it.

Tools like https://highlightviewer.io/ help record and replay these sessions, so you get a clear look at what’s happening without needing to stand over someone’s shoulder.

To get started, pick a specific question you want to answer. Don’t try to watch everything at once—it helps to focus. Are people clicking that new button you added? Are they filling out the sign-up form or getting stuck somewhere? Once you know what you're looking for, it’s easier to spot patterns.

Next, watch a few sessions and take notes. You don’t need to look at hundreds—just enough to see if people are reacting the way you expected. You might be surprised at where people slow down or where they breeze through.

Finally, use what you learn to tweak your product. Maybe the button should be bigger. Maybe the instructions need to be clearer. Testing your changes in new sessions helps you see if things are improving.

At the end of the day, there’s no better way to know if you're on the right track than watching real people try to use your product. User sessions are simple, honest, and super helpful for checking if your ideas actually work—and making them better if they don’t.
