YouTube automation, in plain terms

The words that come up when you look at comment moderation, API limits, and approval-first automation. Each entry links to the page or guide that goes deeper.

Approval queue
The inbox where every drafted reply, hide, and status change waits for a person. Approval-first means nothing public happens until the creator acts on it. See how the queue works.
Auto-hide
Hiding a comment automatically when a rule matches. Hiding is invisible to everyone except the commenter and is reversible, which is why it is safer to automate than a public reply. Auto-hide vs auto-reply.
Keyword rule
A rule that hides a comment when it contains a phrase you listed. Matching runs locally before the YouTube API is touched, so a keyword hide costs no API quota. How to write rules that work.
Author blocklist
Hiding by channel ID rather than by message. It keeps working when a repeat offender changes their display name or rewords the pitch.
Canned reply
A written answer for a question you get on every upload. Each canned reply carries its own auto-post toggle, so it can wait for approval or send unattended. The four rule types.
AI triage
Using a model to classify each comment (spam, question, praise, and so on) before deciding whether a reply is worth writing. Classification runs first; drafting only happens when it adds value. The pipeline.
API quota
The daily allowance YouTube gives a project, roughly 10,000 units. Reading a channel's comments costs one unit per poll; posting a reply or changing a comment's status costs 50. How quota is tracked.
Spam velocity
The rate at which a channel posts replies. A burst of replies in a short window is one of the clearest signals of automation, so paced sending matters more than the total number. What gets a channel flagged.
YouTube Data API v3
Google's official interface for reading and writing to YouTube. Access runs through Google OAuth, so a tool never needs a channel password.
Held for review
A YouTube Studio state where comments are kept back by your moderation settings instead of publishing. The Held tab is easy to forget and often fills up. The settings most creators miss.
First comment
The comment the creator leaves first on their own video, usually to start a conversation. A first comment works as a prompt, not as a place to drop a link. Using the first comment.
Community post
A post on the YouTube Community tab. It supports text, image, and poll formats and needs no upload. YouTube exposes no API for it, so tools plan and remind rather than publish. Planning Community posts.
Scheduled publish
Uploading a video early and setting the moment it goes live. YouTube stores the upload and flips it public at the publish time you choose. How scheduling works.
