Yafa

somewhere between an idea and something real.

[Yafa @YafaHodis]

Built this yesterday for #parisdevdayhack. Burned 90% of my Codex quota 😅

3 compiled languages, 3 connected pieces:
Go backend on my VPS, Strata for versioned agent memory, Zenoh for real-time events
Native iOS app in Swift
C++ firmware on an ESP32 at home

@borvibe @joinhexa @OpenAIDevs @OpenAI Thanks again so much for the opportunity @borvibe 🙌
Loved the hardware + build-in-public tracks, catching up, chatting and meeting so many great people like @0xSorcier and @Andy_AJT. I've got plenty ideas to make it even better. keep building and sharing here

A bientôt 🧚

[Yafa @YafaHodis]

Leaving home for @joinhexa, Paris DevDay finale in 30 minutes 🤞
Looking forward to meeting everyone and seeing the other project
A little more about Yafa 🧚 https://t.co/PpxJH9HBZw

@borvibe @OpenAIDevs @OpenAI Thanks @borvibe 🔥 ! Fitting the story AND the demo into two minutes was a big challenge 😅
Hope even with the short demo, it comes across how the home device and the apps complement each other.. there's a lot more working stuff I didn't get to show 🧚

GPT-6.1 Sol High is pretty amazing. And a little terrifying when you realize how much you can build in a single weekend 🧚

23/ Submitted 🧚
Had a blast building Yafa at home. Video focuses on the why. But have a lot of more demos and funny interactions. Maybe a hackathon project I ll actually keep using

Thanks @borvibe @oleksandrtsp ❤️

3/ Six hours of sleep later,
Time to catch up. We've got something to build ☕️ 👀

22/ Kitchen update 🧚
the Yafa app sent a notification to my iPhone reminding me to make a tomato & feta tart.. while I was already making it

Already on it, Yafa 🧑‍🍳

21/ Connecting Tools for better balance:
Spotify, Codex, calendar, iPhone Screen Time and health data: steps, sleep, etc.
One context, one orchestrator

19/ Back to the essentials: where will Yafa s agent live?

A 24/7 brain on my private VPS, coordinating tasks, chats and shared memory so desktop, mobile and home can keep the same thread

20/ The backend for my personal VPS, booting up 🙌

The pieces are coming together. Next up: the demo 👀
But first, one important time: dinner 🍽️
Everyday balance means making room for it

17/ Bonus: a quick 3D how-to

One image => @tripoai => @Blender => @threejs, and a couple of homemade skills, driven by a conversation with Codex. Prompts, homemade expressive eyes and @higgsfield APIs to make a cool ANSI-style video

17/ A Yafa widget on the iPhone Home Screen: what’s done + just one next task. Your ADHD brain will says thanks

iPhone notifications triggered from cloud. A little presence, without the weight of the whole backlog

[Yafa @YafaHodis]

15/ No time to waste. Building the app
Mobile first, desktop next. The idea:
A to-do showing what’s done and what’s next, updated by the assistant. No Create button.

Chat + voice to talk to Yafa away from home.

#parisdevdayhack @OpenAIDevs @OpenAI @borvibe @oleksandrtsp

[Yafa @YafaHodis]

14/ Same thread. Different places.
The goal: one personal assistant, shared memory across desktop, mobile and home. My own VPS for context, OpenAI Live for voice

12/ What could that look like?

Eat at 15:00. Shower. Finish work. Post on X. Publish the video before midnight.

Help keeping the thread, even while cooking or reading. That’s what we’re exploring.

10/ So, what is Yafa actually for?
A chat with Boris helped sharpen the question: could AI support everyday life as much as work ? With ADHD, I feel that gap even more: I can build for hours and still forget the basics

[Yafa @YafaHodis]

@OpenAIDevs @OpenAI @borvibe @oleksandrtsp 11/ The idea: add a voice device at home, with a conversation and shared memory across desktop, mobile and home. Less time behind a screen, more support throughout the day

@YafaHodis @OpenAIDevs @OpenAI @oleksandrtsp Very cool!!
Now who is it for? How is it going to help them?

[Yafa @YafaHodis]

@borvibe @OpenAIDevs @OpenAI @oleksandrtsp The rest is coming fast, and we’re only getting started 🚀

[Yafa @YafaHodis]

8/ Work in progress, Say hello to Yafa 👋
First steps, built with the OpenAI Live API. A small voice interaction, away from the keyboard.
I will tell you more about what this little companion could be useful for soon.
