Like TikTok Comment

TL;DR

Automatically like TikTok Comment on tiktok.com. Pass the text of one top-level comment and find out whether its heart was already on or is on now.

About

On your own videos, your heart puts a "Liked by creator" label under the viewer's comment, a public sign you read it. A bakery that posts a croissant video at 8am can have an agent sort the comments at lunch: pull them with get_comments, skip the ones already marked likedByCreator, heart the twelve friendly ones with this script (one run per comment) and answer the two questions about opening hours with reply_to_comment. Each run opens the comment panel in your signed-in Chrome and hearts the single top-level row that matches. If liked comes back false, the heart did not stay on after the click, so check the video before trying again. The weak spot is matching. With no comment id in the panel, the script looks for a comment containing your text, ignoring case, so a bare "so good" also hits "omg so good". Paste the whole comment. Only the comments the panel loads first are searched, too.

Input

videoUrl required

The video's canonical URL, e.g. https://www.tiktok.com/@someuser/video/1234567890123456789.

commentText required

The exact, full text of the top-level comment to like, as it appears on the video. Comments have no visible ID in the UI, so text is the only handle a caller can read off the page — it must match exactly (including emoji), and must be unique among top-level comments on the video.

Output

liked required
video_url required
comment_text required
already_liked required

Example output

Shape only: placeholder values generated from the output schema, not a real run.

{ "liked": true, "video_url": "https://example.com/item/123", "comment_text": "…", "already_liked": true }

FAQ

Likes a top-level comment on a public TikTok video, matched by its exact text. Idempotent — already-liked comments are reported, not re-liked.
Ask an AI agent connected to Reduck to run reduck/tiktok.com/like_comment, or run it from a terminal with the Reduck CLI: npx @reduck-ai/cli@latest run --script reduck/tiktok.com/like_comment
You do not need one. "Like TikTok Comment" drives the real tiktok.com pages in a browser, so it works whether or not tiktok.com offers an API for this.
Required: videoUrl, commentText.
It returns liked, video_url, comment_text, already_liked.
Yes. It acts as you on tiktok.com: on your own Chrome it reuses your session, and on a Reduck-hosted browser it loads the tiktok.com cookies saved by the Reduck extension.
It makes changes on tiktok.com, like sending, posting, booking or buying something.

Matching looks for top-level comments that contain your text, ignoring case, so "fire" also hits "this is fire" and "FIRE omg". Pass a longer, distinctive stretch of the comment, ideally the whole text as get_comments returns it. A comment that is only a sticker has no text to match, so this script cannot target it.
The script reads only the comments the panel loads when it first opens and never scrolls, so a comment far down a busy video can be out of reach. Capitalisation does not matter and a leading or trailing emoji can be left off, but a typo inside the text gives no match. The same limit cuts the other way: if the comment you meant is out of reach and only one loaded comment contains your text, that one gets the heart instead.
Liking happens in the comment panel on the video page, and that panel shows no comment id, so the script finds the row by its text. Keep the id from get_comments for reply_to_comment or delete_comment, which take it directly.
Only top-level comments, the ones listed directly under the video, can be liked with this script, because it never opens reply threads. The get_comment_replies script can read replies, but Reduck has no script that likes them.

Get TikTok following

List who a TikTok user follows, by @username. Accounts that keep their following list hidden, and private accounts, are reported with a clear reason instead of an empty or partial list; a handle nobody owns is reported as such. For third-party accounts, TikTok caps the list and pads short ones with suggested accounts, so check `total` and `truncated`; results are only fully reliable for accounts you can see in full, such as your own.
