Versions:
ChatLab 0.15.0, the eleventh public build released by digua, is an open-source, local-first chat-analysis utility that imports message archives from LINE, WeChat, QQ, WhatsApp, Instagram and Discord into a high-performance SQLite engine, letting users run arbitrary SQL queries or invoke an integrated AI agent to surface patterns, statistics and reconstructed narratives without ever uploading raw conversational data to external servers. Designed for journalists reconstructing timelines, researchers studying group dynamics, or individuals who simply want a quantified look at their own social history, the program ingests exported chat packages, normalises their disparate formats through an abstraction layer, and immediately renders multi-dimensional visualisations of activity trends, time-of-day distributions, member rankings and keyword bursts. A stream-computing, multi-threaded backend keeps the interface responsive even when million-row logs are sieved, while more than ten function-calling tools can be chained by the AI agent to perform sentiment shifts, topic clustering or relationship-strength scoring. Privacy remains absolute: indexes, derived tables and configuration files reside only on the host computer, and optional cloud-based language-model requests can be disabled outright. Because the project is still in early iteration, the publisher warns that unfinished features and occasional bugs should be expected, and feedback is welcomed to steer upcoming support for Messenger and iMessage archives. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
