Chronicle is a self-hosted life-logging and speech memory ecosystem.

Chronicle Desktop Agent Overview

Chronicle Desktop Agent Session Details

1. Ambient Speech Capture: The Desktop Agent captures audio and transcribes locally via native GPU Whisper, while lightweight Mobile Clients record ambient speech using low-power VAD and stream audio chunks to the server.
2. Central Memory Brain & Daily Topic Indexing: The Sync Server aggregates and processes transcripts across all devices, automatically extracting concise daily topic tags and structured summaries.
3. Hierarchical LLM Retrieval: The LLM navigates structured daily topic hierarchies to instantly recall past discussions, answer questions about previous events, and pinpoint exact moments in time.

• Desktop Agent: Real-time voice activity detection (VAD), GPU-accelerated Whisper transcription, and interactive React timeline interface.
• Sync Server: Central memory repository with automated daily topic extraction, semantic indexing, fast LLM retrieval, and multi-device synchronization.
• Mobile Client: Low-power background audio capture with on-device VAD and automated server synchronization.
