Show HN: Diffwithgpt – Local LLM Summarizer for Git diffs

1 sp1982 0 5/10/2025, 4:44:53 PM diffwithgpt.com ↗

Hi HN,

diffwithgpt.com is a proof-of-concept tool that auto-summarizes GitHub diffs using a locally hosted Qwen/Qwen-8B model. It currently indexes a small set of Go/devops repositories and enriches commits with AST-derived context to improve semantic accuracy.(only past 3y of commits for now) The goal is to evaluate whether lightweight, local LLMs can provide meaningful changelog summaries—or if it's just more AI-generated noise. Any feedback welcome.
