Pick a move
TypeSafe’s decision model, “jev”, reads the conversation and chooses from a fixed bank of moves, such as “ask how the visit went”, “suggest places”, or “end”. It only decides; it never writes to you.
Izmir, Turkey · Your mood. Your way.
EfsoYol
Tell us your vibe. Find your kind of Izmir.
A place guide for teens and young people. Chat with your AI guide to find cafes, parks, food spots, sights, and curated walks called journeys.
Start on the web or try the early Android beta.
A little chat. A little adventure.
Go from “what now?” to “let’s go.”
-
Share your vibe
Tell your AI guide what you’re in the mood for on this outing. Your taste profile helps it find your kind of thing, too.
-
Have a little chat
Your guide asks friendly questions written for you and the specific place. Tap an answer button or type what’s on your mind.
-
Find your next stop
Your guide suggests places or a curated walk called a journey, with opening hours and reviews from public map data. Pick what feels right and head out.
-
Recap & get a reward
After your visit, have a quick recap. Your guide asks real questions about the place, like what made it good and whether you’d go again, before wrapping up. You earn a reward, too.
Technology
How your guide thinks and talks.
One model picks the next move. A small writer puts it into words. The server keeps track.
Find the words
A small writer model turns that move into friendly wording in English or Turkish. It writes each question and its answer buttons for the specific place.
Keep track of answers
The server applies the move itself and records what each answer establishes, such as that your visit was good. That lets the guide know what it still needs to ask.
Your taste and today’s mood
Your taste is represented by a four-axis profile: four dimensions of preference. Your mood is set separately for each outing.
Place facts and your data
Place facts, such as opening hours and reviews, come from public map data collected by our own crawler. Your account details (your name, email and sign-in) are never sent to the AI providers; what you type in a chat, and the conversation so far, is sent to them so they can answer.
What comes next
Food and scene tastes, such as sushi, kebab, calm spots, and clubs; more cities; and the Android app on every release.
About · Mock team intro
Hi, we’re EfsoYol.
We’re a small team with a soft spot for exploring.
We want finding a place to go to feel friendly and easy. A good afternoon can start with a simple “I feel like…”
This is a mock introduction. More about the team is coming soon.
Our mission
Make room for a little discovery.
Help young people explore Izmir in a way that fits how they feel.
A park for a breather. A cafe for a catch-up. A journey when you feel like wandering. We want the first step to feel easy.
Progress · Mock roadmap
Here’s where we are.
A simple snapshot, with more to come.
Web app
Your Izmir guide is ready to open in your browser.
Android
Try the Android app while it’s still taking shape.
More cities
Izmir is the starting point. More cities are coming soon.
For future investors
Personal guidance, focused AI tasks.
Draft - figures coming soonThe problem: knowing your mood doesn’t always tell you where to go. EfsoYol connects that decision to a conversation, your taste, and place facts.
Built today
The guide combines a four-axis taste profile with mood set per outing. The server applies each chosen move and records what answers establish. Our crawler collects public map facts, including hours and reviews. Account details are never sent to AI providers; chat messages and the conversation so far are, so they can answer.
Designed to keep AI costs small
Instead of one large model handling everything, TypeSafe’s “jev” chooses from fixed moves, and a small writer creates place-specific questions and answer buttons in English or Turkish. The server handles the move itself. Running costs have not been measured yet.
Planned
Add food and scene tastes, such as sushi, kebab, calm spots, and clubs; expand to more cities; and include the Android app on every release.
Take your guide along
