Aura is a manifesto for the open-source hardware movement. Firmware, schematics, and the entire AI pipeline are completely public. MIT licensed.
import AuraCore let device = Aura(hardware: "ESP32-S3") await device.configure { config in config.wakeWord = "Hey Aura" config.visionEnabled = true } await device.startListening()
Ask anything. Aura surfaces what you've heard, seen, and said — with full context, instantly.
Advanced digital MEMS microphones focus on the voice in front of you, filtering out background noise for crystal clear semantic extraction.
Everything you hear is processed by LLMs to create a searchable index of facts, tasks, and memories you mentioned throughout the day.
Optimized for high-contrast indoor and outdoor visual recognition.
Direct integration with advanced vision models for near-instant analysis.

Fork the repo, order the components, and build your own aware wearable. Full guides included.
Aura's 2MP wide-angle camera and dual MEMS microphones capture your conversations, environment, and visual context continuously — processing everything on-device with no raw data ever leaving your pocket.
Everything is processed locally on the XIAO ESP32-S3. Audio is transcribed on-device via Whisper. Only anonymised semantic embeddings sync to the cloud. Your raw conversations are never uploaded or stored.
Aura achieves sub-200ms response latency for context retrieval. Queries are processed via a RAG pipeline combining Pinecone vector search and Redis caching — designed to feel instant.
Yes. Aura is fully open-source. The hardware BOM costs ~$50, firmware runs on FreeRTOS, and the full build guide is in the Docs. No soldering experience required for the base build.
Aura pairs with the companion Flutter app on both iOS and Android. The app handles voice queries, memory browsing, and settings sync via BLE. No proprietary ecosystem required.
Aura runs all day on a single charge — designed for 8+ hours of active use. It charges via USB-C in under 45 minutes and enters a low-power standby mode when not actively capturing.
