How it works
How it Works (3 Easy Steps)
1st – Start free in minutes
Sign up and connect a Creator or Business account through Meta's login. No complicated setup — CommentLink never asks for your Instagram password.
2nd – Set your keywords
Choose simple words people already type — LINK, PRICE, GUIDE — or reply to every comment on a post or Reel. Then decide what the DM should send.
3rd – Let CommentLink run it
When someone comments or replies to a Story, the workflow starts automatically. You can still jump in from the shared inbox whenever you want.
For creators
Grow Faster, Engage Smarter, Convert Better
Maximize Every Instagram Post
Put a keyword in the caption. When someone comments PRICE, LINK, or GUIDE, CommentLink can reply on the thread and send the details in a private DM.
Expand Your Reach
Ask them to follow and tap I'm following before the product card or link goes out. CommentLink checks follow status on that tap — it does not silently detect follows.
Build Your Audience
Capture an email in the conversation before the next message or file is sent. You keep a list you actually own, not a thread you have to screenshot later.
Save Time with Smart Automation
See comment replies, DMs sent, and emails collected in one place. The repetitive replies run without you; you still handle the conversations that need a person.
Meta Business Verified
Get Started Built on the Instagram & WhatsApp Business APIs
CommentLink is a Meta-verified business and runs entirely on Meta's official Instagram Graph and WhatsApp Business APIs. Accounts connect through Meta's own login, sending stays inside their rate limits, and messages only go out in response to something a user did. No passwords, no scraping, no shortcuts that get you restricted.
Features
Everything you need to turn engagement into revenue
Keyword triggers, story automation, flows, broadcasts, a shared inbox and the analytics to tell you what is actually working.
Instagram Post Auto Reply
Send an Instagram DM automatically the moment someone comments on your post. Choose the keywords that should trigger it — price, link, info — and CommentLink delivers the product link, offer or lead magnet within seconds. Every comment turns into a conversation instead of a notification you never opened.
Reels Auto-Reply
Reels bring you the new audience, so reply to all of it. Comment-to-DM automation works exactly the same on Reels: set your trigger keyword, write the message once, and every commenter gets an instant auto reply with your link, offer or discount code.
Story Auto-Reply
Answer Instagram Story replies automatically, while the Story is still live. Share a promo code, a booking page or a price list the second someone replies, so you never lose the person who was ready to buy 12 hours ago.
Story Mention Auto-Reply
When someone tags your account in their Story, CommentLink sends a thank-you DM straight away. Turn @mentions into conversations, look after the people resharing you, and send back the link that gets shared again.
Keyword Triggers
One keyword, one automation. Pick the exact words your audience already types — price, link, guide, book, info — and decide what each one sends. You can also reply to every comment, whatever it says, when you would rather not filter at all.
Welcome Openers
Show up to four tappable buttons when someone opens your Instagram inbox — book a call, browse the catalogue, track an order, talk to support. People choose what they need instead of waiting on you, so every DM starts in the right place.
Upcoming Post Automation
Set your keywords and your DM before the post goes live. The automation is armed from the very first comment, so a launch, a drop or a giveaway never loses its first hour of leads.
Engagement Starters
Suggested openers built around what your audience actually replies to. Start more conversations on purpose instead of hoping the comments section does it for you.
Suggest More
Recommend the next product inside the same DM. Once the first link goes out, CommentLink can follow with a matching item, a bundle or an add-on — a simple upsell that runs on its own and lifts the value of every conversation.
Lead Capture
Collect an email address or phone number before the link goes out. Build a contact list you actually own from Instagram comments, DMs and Story replies, and hand real leads to sales with the whole conversation attached.
Flow Builder
Build multi-step DM automation on a drag-and-drop canvas. Ask a question, branch on the answer, wait, follow up, and hand the chat to a human when it matters. No code and no developer needed.
Template Library
Ready-made message templates for sales, lead magnets, giveaways, bookings and support. Pick one, change the wording to sound like you, and go live in minutes rather than starting from a blank box.
Triggers & actions
Every moment worth replying to, handled
A comment, a story reply, a mention, a first message. Pick the moment, pick what should happen, and CommentLink takes it from there.

What it does
Convert your Instagram audience into loyal customers
Four things happen on repeat in every chat-led business. CommentLink automates all four, and keeps a human in the loop wherever it counts.
Comment Automation
Turn Instagram comments into real conversations. CommentLink sends a personalised DM the moment someone comments on your post or reel, so every keyword becomes a lead instead of a notification you never got to.
Story Automation
Make daily stories a growth channel. Reply automatically when someone reacts to or mentions your story, then guide them toward a link, an offer or a booking page while their attention is still there.
Inbox Automation
One shared inbox for Instagram and WhatsApp. Auto-answer the repetitive questions, route the rest to the right department, and keep full conversation history on every contact.
Lead Generation
Capture emails, phone numbers and intent straight from comments, DMs and story replies. Build a contact list you actually own and hand qualified leads to sales with the context attached.

FAQ
Frequently asked questions
Quick answers on setup, compliance and what CommentLink can automate.
CommentLink is an automation platform for Instagram and WhatsApp. It turns comments, story replies and messages into automated DMs, and gives your team a shared inbox, broadcasts, flows and analytics in one dashboard.
Sign up, connect your Instagram Business account or WhatsApp Business number, pick a post and a keyword, write your message, and switch the automation on. Most teams are live in under 30 minutes.
No. Authentication runs through Meta's official login, so CommentLink never sees or stores your password. You can disconnect the account at any time.
Creator and Business accounts connected to a Facebook Page. Personal Instagram accounts cannot use automation — that's a Meta restriction, not a CommentLink one.
Yes. Everything runs on Meta's official Instagram and WhatsApp Business APIs, respects their rate limits, and only sends messages triggered by a user action such as a comment or reply.
No. Flows are built visually on a drag-and-drop canvas and message templates are plain text with variables. Nothing here requires a developer.
Yes. CommentLink supports team members, department-based routing and role-based permissions, so the right people see the right conversations and everything is logged.
Nothing. CommentLink is free to use — every feature is open, there is no price to pay, no card to add and nothing expires. Sign up, connect your account and start.
Yes. The whole product is free — comment-to-DM, Story replies, the shared inbox, flows, broadcasts and analytics. There is no paid plan and no trial countdown. The only money that can show up is WhatsApp conversation fees from Meta, billed to your own WhatsApp Business account.
Not from us. Instagram messaging has no per-message fee from Meta at all. WhatsApp does — and because the WhatsApp Business account is yours, Meta bills you directly at their published rates. CommentLink never resells or marks that up.
