When we were house hunting recently, we had a very specific brief.

We weren’t just looking for a home, we were looking for a home with an annexe. But not just any annexe.

It needed to have:

One bedroom
Space for an office
A separate living area
Two toilets
And crucially, it had to sit to the side of the property, so it felt like “next door” rather than tucked away at the bottom of the garden

If you’ve ever used Rightmove, you’ll know there is a filter for “annexe”. But that’s where the simplicity ends. Because what we actually needed wasn’t a filter, it was understanding.

From filters to behaviour-led search

Rightmove’s move to integrate with ChatGPT is a really interesting step forward.

Instead of forcing users to translate their needs into rigid filters, it opens the door to something far more natural: A conversation.

One where you can say:

“I need an annexe that works for independent living, but still feels connected to the main house.”

And the system can interpret that, refine it, and search on your behalf. This is the shift to behaviour-led search.

Because most people don’t think in filters, they think in outcomes, context, and lived experiences.

Behaviour is already changing

This isn’t hypothetical; we’re already seeing it in the data.

In our latest SearchPulse research:

26.9% of people now use ChatGPT regularly
Among higher-income households, that rises to 49–58%
And 61% of AI users say they switch because it’s faster and easier

That last point matters most. This isn’t about new technology. It’s about removing effort.

When people realise they can describe what they want, rather than build it through filters, behaviour shifts quickly.

The rise of delegated discovery

What we’re seeing is a move from searching to delegating.

Instead of: “Let me browse, filter, refine, repeat…”, it becomes: “Here’s what I need: go and find it for me.”

That’s behaviour-led search in its purest form. And it’s not how traditional search experiences were designed to work.

This is bigger than property

What’s happening here isn’t just a feature update from Rightmove.

It’s a reflection of a much bigger shift in how people discover things.

Search is no longer a single destination. It’s an ecosystem shaped by behaviour.

Our SearchPulse data shows that:

54.8% of 18–24s now use TikTok as a search tool
51% prefer information in visual formats
40% value content from real people

AI now sits alongside this, not replacing search, but raising expectations of speed, clarity, and usefulness.

The real opportunity for brands

The most interesting part of this isn’t that Rightmove has added AI. It’s how they’ve done it.

Instead of building a standalone tool that users have to learn, they’re leaning into a platform people are already using, already trusting, and already building habits with.

That’s behaviour-led thinking.

Because familiarity drives adoption. Every interaction with AI builds context, preferences, intent, and expectations.

Compare that to most on-site AI tools, where every visit starts from zero.

Behaviour-led search in action

This is what behaviour-led search looks like in practice.

Not more features. Not better filters. Just a better understanding of how people actually behave.

Because people don’t think in filters. They think in terms of needs, context, and outcomes.

Filters were built for systems. Conversations are built for humans.

And increasingly, humans don’t want to search. They want to delegate.

Search is no longer about finding; it’s about being understood.

Final thought

The brands that win won’t be the ones that build the most AI. They’ll be the ones who remove the most friction.

Rightmove’s move is a step in that direction. And if SearchPulse tells us anything, it’s this: The shift to behaviour-led search isn’t coming. It’s already here.
