## What it is
PyLingual is a CPython bytecode decompiler that recovers Python source code from .pyc files for all Python versions since 3.6. It can be run as a local CLI tool or through a hosted web service, and uses machine-learning-based segmentation for control flow reconstruction.

## Use cases
- decompile pyc files back to python source
- recover lost python source code from bytecode
- analyze python malware without source
- decompile python 3.12 bytecode
- reverse engineer compiled python packages
- convert pyc to py

## When to choose
- you need to decompile bytecode from modern Python versions 3.6-3.14
- other decompilers like uncompyle6 fail on recent Python versions
- you want a research-grade decompiler with ML-based control flow recovery

## When to avoid
- you only need to inspect bytecode disassembly rather than recover source
- you need guaranteed perfect source recovery - decompilation can be imperfect
- you need a decompiler for Python versions older than 3.6
