Comment Gate
A small tool that helps one YouTube creator reply to comments on their own channel, without ever posting anything without their say-so.
Comment Gate checks a single YouTube channel's comments every five minutes and uses an AI model to draft a suggested reply for each new one. Every draft is shown to the channel owner, who reads it, edits it if needed, and decides whether to approve it.
No reply is ever posted without an explicit human approval of that specific reply. There is no auto-post mode, no confidence threshold that skips review, and no bulk approval that posts replies without reading them one by one.
What it touches, and why
Comment Gate reads comment text, commenter names and channel IDs, and public video details from the owner's own channel, solely so the owner can reply to them. It doesn't collect anything from visitors to this website. The full details, including how long data is kept and what's sent to the AI model, are in the privacy policy.
How it's built
Comment Gate runs on Cloudflare Workers and stores its data in Cloudflare D1. It reads and replies to comments through the YouTube Data API v3, using a single OAuth scope authorised by the channel owner. Reply drafts are generated by Google Gemini.
It's a single-tenant tool: one owner, one channel. There are no user accounts, no sign-up, and no login for anyone visiting this site.
Status
Comment Gate is a personal project under active development. Some of what's described here is already running; some is still being built. This site will be kept accurate as that changes.
