METIS
Upload a repo, an app, or a single file. Tell Metis what you want to learn from it. You get an annotated walkthrough — what it does, why it was likely built that way, and what carries over to your next project. Your source is read in this browser; only selected excerpts are sent for analysis.

Zips cloned locally can include git history (read from the reflog). GitHub's “Download ZIP” contains no history — Metis will say so rather than guess.
