What Is ReplyAuto AI, and How to Automatically Reply to Facebook and Instagram Comments
Meet ReplyAuto AI — how it drafts and safely auto-sends replies to Facebook and Instagram comments, grounded in your Shopify catalog, with risky comments held for a human.
Every brand that posts consistently hits the same wall. A product post does well, and within an hour, sixty comments ask the same four questions. Does this ship to the UK? Is this size available? How much is it? Is this still available? When comments come in bulk, a customer support team tries to answer them; otherwise, potential buyers may wait too long for the information they need.
ReplyAuto AI has been designed to solve these problems. It is an AI response generator for social media comments. Instead of rewriting the same answers, teams can use AI to respond automatically when the AI knowledge score meets or exceeds 88% accuracy. Responses scoring below 88% are saved as drafts for human review before they are sent.
For Shopify businesses, ReplyAuto AI can also use product information, prices, variants, policies, and FAQs to help create responses based on actual store information. This makes the platform more than a basic AI response generator.
This blog explains what ReplyAuto AI does, how Facebook and Instagram comment automation works, and how businesses can use an AI auto reply system without giving up control of customer conversations.
What Is ReplyAuto AI?
ReplyAuto AI is an AI customer reply tool that automatically drafts and sends replies to comments on your Facebook Page and Instagram Business posts. It is a Facebook and Instagram comment tool built around one idea: the AI is never allowed to guess.
The purpose of ReplyAuto AI is to generate answers to any comment based on knowledge — your live Shopify catalog, your store policies, your uploaded FAQs, and your brand voice notes. When a shopper asks about shipping to Ontario, the reply quotes your real shipping window. When they ask about a size, it checks your real inventory.
Four things make up the product:
- Auto-reply: The engine that drafts and, when you allow it, posts. This is the AI auto reply layer.
- Moderation inbox: One table where comments from every connected post land, filterable by date, post, account, or status.
- Knowledge base: The documents and catalog data that ground every reply.
- Analytics: What got answered, what got escalated, what your team actually touched.
Two numbers from the product pages give you the shape of it: drafts arrive in about 2.3 seconds, and 94% of them are sent without edits.
How Does ReplyAuto AI Work?
ReplyAuto AI follows a basic three-part process: connect, index, and reply.
1. Connect
Sign in with Facebook and pick the Pages you manage. One OAuth covers every Page on your account, and any Instagram Business accounts linked to those Pages come along automatically. You do not connect them one by one. Instagram-only brands can connect Instagram directly. Long-lived Page tokens (60 days) mean the connection keeps working instead of dropping every week.
2. Index
Connect your Shopify store, and ReplyAuto AI indexes your products, prices, policies, and FAQs. This step separates a real AI comment responder for Shopify stores from a chatbot. Without it, the AI has nothing to answer from. With it, replies quote real prices and real shipping details.
3. Reply
New comments appear in the inbox with a draft already written. Edit inline and send, or flip the workspace to Auto mode and let the safe ones post as soon as they're ready. That is it. A new account can have its first AI draft ready in under two minutes.
How to Automatically Reply to Instagram Comments
To use ReplyAuto AI as an Instagram auto reply tool, businesses first need to connect an eligible professional Instagram account. ReplyAuto AI supports Instagram Business accounts. Its Instagram page states that comments from connected posts can enter one inbox with an AI-generated draft already prepared.
Step 1: Connect Your Instagram Account
Connect an Instagram Business account directly or through the Facebook Page linked to that account. Once connected, ReplyAuto AI can receive comments made on the business's Instagram posts.
Step 2: Add Business Information
The quality of an Instagram auto reply depends heavily on the information available to the system. For example, an ecommerce company may provide:
- Product information
- Prices
- Available sizes
- Shipping information
- Return policies
- Frequently asked questions
- Brand response guidelines
If Shopify is connected, ReplyAuto AI can use store information as part of its knowledge base.
Step 3: Receive AI Reply Drafts
When customers leave comments, ReplyAuto AI prepares responses using the information it has indexed. For example, a shopper might comment, "Does this shirt come in medium?" Rather than requiring someone to search the catalog and type a response manually, the system can prepare an answer using relevant product information.
This makes ReplyAuto AI function like an AI reply generator, but with an important difference: its answers can be grounded in information supplied by the business.
Step 4: Review or Enable Automatic Replies
Businesses can review replies before sending them. Teams that want more automation can use Auto mode so qualifying responses are posted automatically. ReplyAuto AI says complaints, refund requests, requests for human assistance, and other risky comments can be held for review rather than automatically published. This provides a practical way to manage automated comments on Instagram without treating every customer message the same way.
How to Automatically Reply to Facebook Comments
The Facebook side is nearly identical, with one advantage: coverage is broader from a single connection.
- Sign in with Facebook and select the Pages you manage. One sign-in covers all of them.
- Connect Shopify so drafts are grounded in your catalog and policies.
- Add your moderators. They do not need Facebook admin credentials. Workspace owners connect the Page once, and moderators inherit the ability to draft and send. Nobody shares a password.
- Review drafts in the inbox, then switch to Auto mode when you are confident.
This approach gives businesses a way to manage automatic comments on Facebook while keeping higher-risk conversations with human staff.
How ReplyAuto AI Works With Shopify
Shopify integration is especially important for ecommerce brands using Facebook and Instagram as sales channels. ReplyAuto AI can index Shopify products, variants, prices, availability, policies, and FAQs. That information can then support responses across Facebook and Instagram. This allows an AI comment responder for Shopify stores to answer questions based on actual store details rather than relying only on general AI knowledge.
For example, customers may ask:
- "Is the blue version available?"
- "Do you have this in XL?"
- "What is your return policy?"
- "How long will shipping take?"
If the required information exists in the connected knowledge source, ReplyAuto AI can use it while preparing the response.
Who Uses It
- Shopify brands: store owners selling through Meta who need catalog-accurate answers at post speed.
- Agencies: separate workspaces, roles, and per-client reporting across many client accounts.
- High-volume teams: thousands of repetitive comments cleared on safe autopilot, so humans only handle what needs a human.

A "reply" is any message your workspace sends to a Facebook or Instagram comment, whether a human approved it or Auto mode sent it. Internal notes and dismissals do not count. Allowances reset on the 1st. If you hit your limit, sending pauses but comments keep arriving and the AI keeps drafting.
Which Comments Should Be Automated?
Not every comment needs the same workflow. Automation works particularly well for repetitive, factual questions such as:
- Product availability
- Product options
- Basic shipping questions
- Store information
- Common policy questions
- Frequently asked product questions
Human review is usually more suitable when a customer is:
- Making a complaint
- Asking for a refund
- Reporting a complicated problem
- Requesting a person
- Discussing a sensitive issue
- Asking something the system cannot answer reliably
ReplyAuto AI specifically states that complaints, refund requests, and comments requiring a human can be routed for review rather than automatically posted. This helps make AI auto reply useful without turning customer service into fully unattended automation.
Benefits of Automatically Replying to Social Media Comments
Faster Response Times
Customers asking purchase-related questions often want information immediately. An auto response system can reduce the delay between a customer's comment and the business's answer.
Less Repetitive Work
Teams often answer the same questions every day. Automating routine responses means employees do not need to repeatedly write basic answers about prices, sizes, availability, or policies.
More Consistent Answers
A useful reply generator can reference the same business information across many responses. That helps reduce situations where different employees provide different answers to the same question.
Better Coverage During Busy Periods
Posts can receive comments outside business hours or during campaigns when comment volume suddenly increases. Automated drafting allows more comments to enter an organized response workflow.
Human Attention Goes Where It Matters
Instead of spending most of the day answering basic questions, team members can focus on complaints, unusual requests, complex purchasing questions, and conversations that need judgment.
Turn Facebook and Instagram Comments into Faster Conversations
Facebook and Instagram comments are no longer only reactions to social posts. For many businesses, they are product questions, support requests, purchase signals, and opportunities to speak with customers. ReplyAuto AI gives businesses a way to manage those conversations without manually typing every response.
By connecting Facebook and Instagram, adding reliable business information, and choosing which responses require approval, companies can use auto reply technology without removing people from situations where they are still needed. Businesses interested in testing the system can get ReplyAuto AI and connect their accounts to see how automated Facebook and Instagram comment replies fit their current support workflow.
