Turn any snippet into a walkthrough
highlit is a publishing tool for understanding code. Paste a focused snippet and highlit builds an interactive explainer page — a guided, step-by-step walkthrough that highlights the exact lines as a short narration explains the logic one idea at a time. Share it as a live page, embed it, or publish it to the library.
The walkthrough difference
Most code explanations are a wall of comments or a video you can't skim. highlit breaks your snippet into ordered steps. Each step highlights the lines it's about and narrates the idea behind them, finishing with three takeaways. It's a live page, not a recording — readers step through at their own pace, click any line, or copy the code.
Who it's for
Developers documenting a tricky function, teachers and course authors, people writing tutorials or READMEs, and anyone onboarding a teammate to unfamiliar code. It works across languages — Python, JavaScript, Ruby, Go, and dozens more — and tunes the explanation to the snippet in front of it.
How it works
No subscription. You start with three free explainers, then buy credits only when you need more — they stack and never expire. One credit makes one explainer; sharing, embedding, and PNG export are always free. Make an explainer public and it joins the library — and you earn a credit back for every few you publish.
