Instagram auto free: 
Most people see IG comments as just likes or quick reactions. But what if those comments could start real conversations and attract leads automatically? That’s exactly what Instagram auto-free comment automation helps you do.
Instead of replying or sending DMs on your own, you can build a simple system that does the work for you. On this page, we’ll show you how to turn everyday comments into meaningful interactions, grow engagement in a natural way, and capture leads with no ads, boosting posts, or complicated tools.
What is Comment to DM Automation?
Comment to DM automation sends automatic direct messages when users comment specific keywords on your IG posts. The system works in three simple steps: First, you create a post offering something helpful, be that a guide, a checklist, or a discount. Second, you ask followers to comment with a specific word like “CHECKLIST” or “GUIDE”. And third, when they comment on that word, they get an instant DM starting a conversation.
The Instagram post automation goes far beyond single messages. You can build whole conversation sequences that collect contact info and deliver your content, everything within the app’s messaging system.
Why Auto-Reply to Instagram Comments?
Old-style Instagram lead funnels follow a specific pattern:-
Post content with a call-to-action, direct users to “link in bio”, send them to a landing page, and wait for form submissions.
The numbers reveal the problem with this approach. When you send 1,000 people to a link in bio, approx 800 never click. They scroll ahead, get distracted, and find the extra step too difficult.
Out of the 200 people who tap on your landing page, only 10 people complete the signup form. That’s a conversion rate of 1 percent.
This approach has another cost: algorithm penalties. Instagram prefers content that keeps users on the platform, because that’s where it shows ads and generates revenue. When your posts actively drive people away from Instagram, the algorithm reduces the reach of your content.
The Chat Funnel Alternative
An auto poster for Instagram chat funnels keeps the whole procedure within the app. You ask for a comment with a specific keyword. The time someone comments, your automation replies to their comment publicly and sends them a DM privately.
Within the DM, you’re working with natural conversation flow rather than form fields. You ask for their name, they reply. You request their email, and they offer it. You deliver the promised resource right away.
The conversion data reveals a notable difference. With the same 1k engaged followers, a chat funnel usually converts 500 people, not just 10. That’s because you eliminate the friction points – no external URLs to tap, no pages to load, no forms to fill in.
The engagement metrics improve as well. Each comment registers as an engagement signal. Your automated reply adds another signal. Each message in the DM conversation creates more engagement data. The platform interprets this activity as content quality, which expands your organic reach.
Claire Bartholic, who coaches plant-based runners, used this Instagram automated posting approach by asking followers to comment “GUIDE” on her posts. Her auto-post or automation approach collected over 2,000 email addresses with an 80 percent conversion rate.

Boost Leads with Comment Automation
An Instagram auto-posting chat funnel needs three essential components, which include the following:
- A common trigger
- A message sequence
- A content delivery system.
The comment trigger activates when users type specific keywords. If you offer a fitness checklist, you might use “CHECKLIST” as your trigger. Include common misspellings such as “CHECKLIST” to catch all variations.
The message sequence guides users from comment to conversion. A basic sequence includes:-
- Confirmation of what they’ll receive
- A request for their first name
- A request for their email address
- Immediate delivery of your offer
The delivery happens through a direct URL or file sent through Instagram DM. No external websites, no loading delays, or no technical complications.

How to Set Up Comment to DM | Step-by-Step Guide
Creating auto upload Instagram automation hardly takes 30-45 minutes using Manychat, which is a Meta-approved automation platform.
1: Set up and Connect Your Manychat Account
Go to Manychat and create a free account. The platform offers a free plan, containing basic features, and paid plans starting at $15/month for advanced capabilities.
Connect your IG account by clicking “Get Started Free” and selecting Instagram from the options. Follow the prompts to authorize the connection. Be sure you grant all requested permissions, because missing permissions cause automation failures.
2: Set Up Your Comment Trigger
Head to Automation in Manychat and tap on “New Automation.” Add a new trigger once you select “User comments on your Post or Reel.”
Select your trigger scope. Choose “All posts or reels” to make the automation work across all your content, or pick “Specific post or reel” if you want to test on specific posts first.
Decide on your trigger keywords. For instance, if you’re giving away a muscle-building guide, add “GUIDE” as your primary keyword. Add variations like “Guide,” “guide,” and common misspellings like “GUIDE.”
Create your public reply comments, which appear under user comments in your post. Write 3-4 variations to avoid looking spammy.
- “Check your DMs for instant access!”
- “Just sent you the guide—check your messages!”
- “It’s waiting in your DMs (might be in message requests).”
Manychat randomly rotates through these variations.
3: Build Your Initial DM Message
Click on “Instagram” to add your first message in the automation, which will automatically send a message immediately as someone comments on the post.
Write a confirmation message stating what they’re receiving. For instance:-
Ready to build more muscle?
My free guide gives you 8 exercises anyone can do gain muscle effectively.
Tap on the button below or reply ‘YES’ to get your guide now.
Add a Quick Reply Button labelled “YES, send it!” This button triggers the next step in Instagram automated posting.
Important Note: Add a text-based alternative, i.e., “reply YES,” because Instagram desktop users can’t see quick reply buttons.
Make sure “Send as Private Reply” is turned on at the top of this message. If you don’t do so, the automation won’t work properly.
4: Create Your Follow-Up Automation
Create a second auto poster on Instagram to handle the actual lead collection. Click on “New Automation” again and add a trigger for “User sends a message.”
Set the trigger to “message begins with” and add your keyword “YES” plus variations like “Yes,” “Yeah,” and “Yea”.
Add your first message in this automation. Keep it brief:
“Perfect! This will only take a minute to get your access set up.”
Add a 3-second delay after this message to make the conversation look natural, not robotic.

5: Gather User Information
Add a Data Collection element to ask for the user’s first name. Set the Reply Type to “First Name,” so Manychat recognizes name formats—Set Data Collection to expire in 23 hours to give users time to respond.
Scroll down and delete the Skip button text. This forces users to provide their name. They can’t bypass this step.
Connect this to a new message block. Once they provide their name, send a greeting adding:-
“Nice to meet you, {{first_name}}! One more quick step.”
Add another Data Collection element for email. Set Reply Type to “Email” so Manychat validates the format. If someone enters an invalid email, Manychat automatically asks them to try again.
Again, delete the Skip button text to make email collection mandatory.
6: Deliver Your Content
After collecting their email, send your final message with the promised content:-
“You’re all set, {{first_name}}!
Your guide to building more muscle is ready. Click below to access it now.”
Add a button labelled “Get My Guide” that links to where your guide is hosted (Google Drive, Dropbox, or your own website)
Tap on “Set live” on the top side to activate your automatic upload to Instagram.
7: Connect Your Automations
Return to your first automation (the one triggered by comments). Connect the Quick Reply button to your second automation, adding a “Start Automation” block and selecting your follow-up automation from the dropdown.
Click “Set live” on this automation as well. Your complete automatic post system is now active.

Auto-Reply Not Working?
If your auto-publish Instagram automation fails to trigger, two issues cause 95% of problems:-
Connection Problems – Perhaps your IG account is not properly linked to Manychat. In this case, return to settings in Manychat, select Instagram, and verify all permissions are granted.
Expired Permissions: Periodically, Instagram revokes automaton permissions without notification. To re-establish the connection and solve most issues right away, go to Settings → Instagram → “Refresh permissions” and click the button.
Tips for Writing Auto Replies
Tip 1: Align Your Post Content With Your DM
Your post and first DM message must match exactly. If your post offers a free productivity guide, your first DM should reference that productivity guide specifically.
Avoid writing posts about “getting started” and then sending DMs asking, “Do you want my checklist?” Users won’t make the connection.
Tip 2: Write Strong Public Reply Comments
The comment that showcases publicly after someone triggers your automation determines whether they check their DMs. This single comment is important. If users don’t open their messages, your entire funnel fails.
Make your public reply comment spark excitement and urgency. For instance:-
- “This is exactly what you need—check your DMs now!”
- “Just sent you something valuable, check your messages!”
- “Can’t wait for you to see this! It’s in your DMs 📩”
Tip 3: Minimize Steps to Conversion
Every additional step in your Instagram auto poster reduces completion rates. If someone wants your discount code, send them that. If they want a guide, deliver the guide once you collect their email.
Tip 4: Use Conversational Language
Write messages in active voice with simple, direct language. Keep every message below 300 characters when possible. If your automation sounds like a robot, rewrite it again.
Final Words!
Comment-to-DM automation transforms how accounts on Instagram convert engagement into leads. Old link-in-bio funnels convert nearly 1% of engaged followers, while Instagram auto chat funnels convert 50% or above of the same audience.
Start with a single post. Ask your audience to comment on one specific word. See how many people enter your DM funnel. Measure your conversion rate. Then scale the system around all your content.
Although the technical setup is quite simple. The templates are readily available. The platform is proven. The results are measurable. So, what are you waiting for? Try it now.
