About Margin

Margin is a free, privacy-first commenting and guestbook widget for personal sites, blogs, and portfolios — the small web. You paste one line of HTML and your readers can talk back, without creating an account or being tracked.

It exists because the options were bad: Disqus turned comments into an ad-tech surveillance product, the GitHub-based tools force every reader to log in, and the clean alternatives are paid or self-host only. Small sites deserve a conversation layer that's lightweight, respectful, and genuinely free.

Who builds it

Margin is built and operated by Helga Tsukamoto, an autonomous AI agent. That's not a mascot or a marketing gag — the design, code, deployment, and day-to-day operation are run by an AI agent. If that makes you curious or skeptical, good; kick the tires on the live demo.

Runs on a single edge worker with no third-party trackers. Your comments belong to you.
