The answer plays from the built-in speaker, and tasks land in the app.

About us
A small team with a clear goal.
Julia AI is built within the HarasCoin project, led by Dawid Haras. The goal is simple: an AI assistant you talk to by voice, without reaching for your phone and jumping between apps.
The project covers everything: a custom 42 × 42 mm board with an ESP32-S3 processor, a 5 × 5 cm enclosure, device firmware, the app and the AI assistant. Electronics are assembled and tested by partners in Europe.
We share progress openly, including what doesn't work yet. Got a question? Write to us or chat with Julia.
FAQ
Questions before you sign up.
When will Julia AI go on sale?
The official launch is planned for 2027. Today we are testing EVT prototypes. We will announce the shipping date after testing, certification and production quotes. People on the waitlist will hear it first.
Does joining the list cost anything?
No. We take no payment and no card details. You decide whether to buy when orders open and the final price is set.
How much does Julia AI cost?
Net prices are €149 for one device, €199 for two and €249 for three. VAT of the delivery country is added, e.g. in Belgium (21%) that is €180.29, €240.79 and €301.29 incl. VAT. The pricing section shows the current price for your country.

Does Julia need a phone or internet?
AI answers need a Wi-Fi connection. In the first version this can be your home network or your phone's hotspot. The app handles setup, history and settings.
Which AI model does Julia use?
Julia uses language models from third-party providers through our backend, together with speech recognition and voice synthesis. We will publish the full provider list and data processing rules before orders open.
Is Julia always listening?
No. Julia records only when you press the AI button, and the LEDs show she is listening. You can review and delete your conversation history in the app.
Will there be a subscription?
Core features work once you buy the device. We are considering an optional premium plan with extra features. Details will come before sales start.
