FacebookBeautifulHehe you're sweet 😉

Replies stay short and playful, and fans who write in English or Thai get a reply in the same language. Each step below explains how she gets this result.

Before you start: prepare three things

  • A short intro: who you are, what you share, what fans call you
  • Ten comments you answered yourself: from recent posts, they show your voice best
  • Links to send fans to: a LINE account, course, product page or booking page

Step 1: Write your persona and voice in the notebook

Open the FRIDAI dashboard, choose the comment account, and click "AI Rules (Notebook)" on the left. On the Write tab, add two sections: a persona saying who you are and what you share, and a reply style covering length, catchphrases and emoji. Stuck? Click "AI Auto Setup" at the top for a draft to edit.

The more specific your voice, the more it sounds like you. The "AI女友李婷婷" voice took many versions to settle. Today it says:

  • Every reply is under 10 characters
  • Playful and self-⁠mocking, like chatting with a friend
  • No emoji in the reply when the fan used none
  • Pick a different heart colour each time instead of always ❤️

Tip: first drafts are usually too long and too eager. Read ten replies, then turn the length and warmth down to find your tone~

Step 2: Write reply rules for each kind of comment

Add a "Reply rules" section to the same notebook. Group common comments and say how to answer each:

Comment typeSuggested rule
PraiseAccept it happily, say thanks briefly
QuestionsAnswer simply, point long answers to a video or DM
CollaborationsAsk them to send an email
Personal questionsDeflect with humour, never share address, relationships or income
TrollsNo arguing, close calmly
Helping pick photosWhen a fan replies with a number, answer "Number 2 gets a vote~"

Then click Test in the top right and try a few fan comments to check each reply sounds like you.

Step 3: Set comment-⁠to-⁠DM to lead fans onward

To send fans to LINE, a course or a product page, use "Post Keyword DM". Click "Add Post", then pick one of your recent posts or paste a post link. This needs both a comment plan and a DM plan.

After clicking Add Post, choose a post from your recent posts

Then set up a rule for that post:

  • Trigger Keyword: a comment containing this word triggers the rule, such as "checklist"
  • DM Content: the message and link sent to the fan
  • Comment Reply: a public "Sent you a DM" line. Add a few variations and one is picked at random each time, so it reads naturally
  • Two-⁠step claim: the DM first sends a button and the link follows after the fan taps it, which brings more replies and keeps the link out of the first message

"AI女友李婷婷" often writes "comment 'add me on LINE'" in a post. When a fan does, the public reply says "Sent you a DM⁠~" and the DM carries her LINE link and a short intro. The public reply shows other fans how to join, and the DM puts the link in the fan's hands.

Step 4: Choose which comments need no reply

Open reply settings and go to "Reply exclusions". Turn on "AI Smart Skip", and the AI decides whether each comment needs a reply, skipping emoji-⁠only comments and friend tags. You can also turn on "Smart Hide" and describe comments to hide, such as spam or suspicious links.

Step 5: Set a human reply pace

Under "Timing & frequency", limit how many replies one person gets in a time window. "AI女友李婷婷" uses 3 replies per person per 60 minutes and 2 per person per post on her Facebook Page and Threads, so even an eager fan sees a natural rhythm.

Timing & frequency settings: 60-minute window, 3 across posts, 2 per post per person

This page also sets live-⁠comment limits, reply probability and reply delay. A few seconds of delay makes replies feel like you answered while scrolling.

Step 6: Set human handoff

Open "Human handoff" and decide what comes back to you:

  • Comment Review Mode: the AI drafts each reply and waits for your approval, good for week one
  • Human Takeover Detection: the AI pauses while you reply yourself
  • Skip comments you've already replied to: comments you answered in the app get no second reply
  • Comment Notify-⁠Human Sensitivity: slide right to be notified about more comments

Tip: run review mode for a few days after launch, then switch it off once every reply sounds like you~

Step 7: Check replies in the comment center

Leave a few test comments from a second account, then open "Comment Center" on the left. AI replies carry an AI label so you can check tone and content one by one. Click Reply to add your own answer, or "AI Reply" to have the AI answer again.

A quick note from FRIDAI

The heart of an AI twin is writing down how you would reply. The switches just control the pace. In short:

  • Capture your voice with a persona and specific length rules
  • Write rules for praise, questions, collaborations, personal questions and trolls
  • Use post keyword DMs to send fans to LINE, courses or products
  • Turn on AI Smart Skip and set reply limits for a human rhythm
  • Use review mode in week one and check the comment center daily

Put ten comments you recently answered into your notebook, and let me try replying in your voice ☺️

FAQ

What does a KOL need to set up an AI twin?

A short intro, ten comments you answered yourself and the links you want fans to reach. FRIDAI's AI Auto Setup can produce a first draft that you then edit into your own voice.

Can one AI twin reply on Instagram, Facebook and Threads?

Yes. Each platform account gets its own comment plan, and accounts can share one notebook, so a change to voice or rules applies to all of them.

Will fans notice the replies come from AI?

Mention in your bio or a pinned post that an AI twin helps you reply, and fans will feel more at ease. A specific voice, short replies and a slower pace keep replies close to your own.

Which plans does comment-⁠to-⁠DM need?

Post keyword DMs need both a comment plan and a DM plan, so a DM can go out after a fan comments.

I want to answer some comments myself. Will the AI jump in first?

Turn on human takeover detection and skip comments already replied to, and the AI will not reply where you already have. Add a reply delay to give yourself time to answer first.

How much does replying to thousands of comments cost?

FRIDAI comment plans start at US$70 a month with 500 replies, with US$160 and US$300 plans above that. You can also try it for 30 days for a one-⁠time US$1.

How FRIDAI can help

FRIDAI keeps your voice, rules and links in one notebook, replies to comments on Instagram, Facebook and Threads, and hands judgment calls back to you, so your time goes into creating.
