Is this the same matching Chat33 uses?

Yes. The tester runs the same code that decides, for every real comment, whether a comment-to-DM flow starts. If it says a comment matches here, it matches in your flow.

Does a keyword match inside a longer word?

No. Matching is by whole words, so GUIDE does not match "guidebook" and LINK does not match "LinkedIn". This keeps short keywords from firing on ordinary comments.

Should the keyword be in capitals?

It does not matter for matching. Capitals in the caption ("Comment GUIDE") just make the word easier for people to spot.

What happens if two keywords match the same comment?

Only one flow starts. The longest keyword wins, so PRICE LIST beats PRICE. If they are the same length, the older flow wins.

How are emoji matched?

Each emoji counts as a word of its own, so "GUIDE🙏" still contains the word GUIDE. Skin tones are ignored, so 👍 and 👍🏽 are the same.

How comment keyword matching works

Whole words only

GUIDE matches "guide please" but not "guidebook". SALE does not match "sales". A keyword is found when its words appear in the comment as separate words.

Capitals, accents and punctuation are ignored

"GUIDE!!", "guide" and "Guíde" are the same word. Emoji count as words of their own.

Several words must appear in order

PRICE LIST matches "send the price list" but not "list the price". The words can sit anywhere in the comment, as long as they follow each other.

One comment starts one flow

When several keywords match, the longest one wins: PRICE LIST beats PRICE. With equal length, the older flow wins. Two live flows on one account cannot share the same keyword, so a newer one never silently loses.

If your keyword matches but no DM arrives

Matching is only the first step. The guides below cover what happens after it.
