Building tours at the speed of a walk | Headout Hackin'
Creating a great tour usually means retracing every step. WalkieTalkie turns the walk itself into the production session, letting guides capture routes, photos and voice notes in real time and transform them into immersive Dex experiences.
Building a great walking tour begins long before anyone writes a script.
Someone has to visit the place, walk the route, understand how the streets connect, notice which details are easy to miss, photograph the landmarks, read the plaques and work out what is actually worth telling a guest as they move through the space.
In the early days of Dex production, that usually meant flying out for a recce, walking for hours, taking hundreds of photographs and recording a collection of hurried voice notes, only to return home and discover that the most useful part of the visit was still trapped inside the person’s head. Perhaps a section of the route had been missed, a checkpoint was on the opposite side of the street, or the path made perfect sense while standing there but became difficult to reconstruct from a camera roll several days later.
So the team would go back.
There is no elegant way to describe it: early Dex production depended on return trips, not because the team lacked attention or preparation, but because there was no reliable way to capture a place while experiencing it. You walked away with memories, photographs and fragments of information, then tried to manually turn all of them into a structured tour from somewhere else.
Dex WalkieTalkie began with a simple question: what if the walk itself could become the production session?
Just walk and talk
The premise is deliberately simple. Open the app, begin walking and describe the place as though you were showing it to a friend beside you. Take photographs when something catches your attention, scan a placard when it contains useful information and continue moving without worrying about checkpoints, scripts or how any of it will eventually fit inside Dex Studio.
WalkieTalkie captures the audio, GPS trail, photographs, timestamps and text scanned along the route, then transcribes the recording, identifies potential checkpoints, infers the paths connecting them and passes the material to a production agent.
The agent works out what matters, arranges it into a coherent sequence, writes the tour script and layers in narration, music and sound design, before returning a link to a playable Dex tour that can be opened directly in the Headout Dex app.
The target was ambitious: a 20-minute walk should produce a complete first draft of a tour in under ten minutes. During the demo, it did.
The difficult part was not the app
The iOS capture experience was not the hardest problem. Turning the walk into an itinerary was.
People do not naturally speak in structured checkpoints. They say things such as, “just past this corner, there is something most people completely miss,” while continuing to walk, changing direction and pointing their camera towards an object that may or may not be visible in the frame. That is not clean data. It is a person navigating through context, instinct and memory, which is also how people genuinely experience a place.
Most of the 42-hour build went into teaching the system to make sense of that raw stream: scattered audio, noisy GPS data, photographs taken at strange angles and observations that only became meaningful when placed in the correct order. The task was not simply to transcribe the speaker or plot coordinates on a map. The agent had to determine which moments deserved to become checkpoints, how the guest should move between them and what larger story the person had been trying to tell while walking.
It took time to get right, but once the finished tour opened inside Dex, with its checkpoints, narration and music intact, the potential became immediately visible.
Neil owned the product vision and built the iOS capture app end to end. Anurag developed the backend and deployed the AI agent, DAW integration and supporting infrastructure in time for the demonstration, while Ajith led the design, creative and branding so that the result felt like a product rather than a collection of connected prototypes.
The team called itself Lukewarm. The reaction when the tour opened in Dex was anything but.
From production tool to city-scale platform
WalkieTalkie has the potential to solve two problems at very different scales.
The immediate one is internal production. Every recce can become a structured capture session, which means the person returns with a GPS trail, photographs, audio and a functioning tour draft rather than a memory and a long list of work still to be done. A process that previously took days could begin taking minutes, while the manual setup required for early tours could fall by more than half.
The larger opportunity is density. Dex becomes much more powerful when it extends beyond a handful of tours around famous landmarks and begins to reflect the depth of an entire city: a food walk through a market, a hidden-history route through an old neighbourhood or an architecture trail shaped by someone who has lived there for decades. A central production team will never possess all of that knowledge, and a generic AI product trained on information from the internet will not possess it either. The best local stories often live inside guides, venue employees, historians, food obsessives and residents who know why one doorway matters, which lane visitors overlook and how a neighbourhood has changed over time. WalkieTalkie gives those people a way to contribute without learning Dex Studio or becoming trained producers. They only need to walk through a place and talk about what they know.
That is how Headout can build a layer of human, place-based knowledge that cannot be replicated by generating more content from the same information already available online.
Hackin’ at Headout is our internal hackathon, where small teams have less than two days to turn real business problems into working products. Interested in building with us? Explore open roles at Headout.
