Aura2026 · Local AI assistant

Aura is a personal assistant that runs on my own computer. It understands voice and text in Portuguese, answers out loud and handles the shopping list, the weather and the state of the machine, without sending the conversation to the cloud.

What it does

Talks and listens in Portuguese, with an animated face
Manages a shopping list and a product catalog with barcodes
Shows the weather and the state of the computer
Runs actions by fixed rules, each one with a receipt

What it makes possible

Assistants that keep your data on your own hardware
Voice and text control over your own systems, with confirmation before changes
Receipt import with RAG (in progress)
Long-term memory through a semantic memory (planned)

React, FastAPI, PostgreSQL, Ollama

Aura in use, listening, speaking, showing and editing the shopping list with voice commands. The video starts muted; use the controls to turn the sound on.

Your problems come first, then the code.

Poorly defined projects lose time and quality. I spend the first days inside your business so the build starts from the right question.
