A program to automatically generate commit messages locally without an LLM?

Ello Ello. Can you recommend a program with which I can generate commit messages locally? I DO NOT want an LLM local or cloud API. What I want is a tiny or small language model. If I could easily swap or customize the model for each project, it would be better, too. So I could have smaller models for specific projects. I can do the training meself. Thanks in advance!
