These are ecosystem siblings—aivmlib is the core utility library for handling Aivis voice model files, while aivmlib-web is a browser-compatible port of the same functionality for web environments.
About aivmlib
Aivis-Project/aivmlib
Aivis Voice Model File (.aivm/.aivmx) Utility Library
Provides Python API and CLI tools to read/write voice synthesis model metadata (speaker info, licenses, audio samples, style vectors) embedded in Safetensors (.aivm) or ONNX (.aivmx) container formats. Implements the reference specification for the AIVM open format standard, enabling seamless model distribution and integration with AivisSpeech and compatible synthesis engines.

Aivis-Project/aivmlib-web
Aivis Voice Model File (.aivm/.aivmx) Utility Library for Web
Provides TypeScript utilities for parsing and manipulating AIVM/AIVMX model files—which bundle trained voice synthesis models, hyperparameters, style vectors, and speaker metadata (name, license, icon, samples) into single containers. Parses both Safetensors-based (.aivm) and ONNX-based (.aivmx) formats with standardized metadata schemas. Browser-only library designed to integrate with AI voice synthesis applications like AivisSpeech and AivisSpeech-Engine.
