Hundreds of comments, auto-replied

Viewers comment one word under a video and get a private message with the link within seconds, on Instagram and Facebook. Built on Meta's own API with no ManyChat subscription, it has answered hundreds of comments automatically.

Hundreds of comments, auto-replied

In the first audit, every single Instagram comment had got its message. On Facebook we found a handful that had slipped through (unusual spellings and closed messages), fixed both causes the same day, and answered all of them. The bot went from idea to live in one day.

/ The challenge

Where the bottleneck actually was

Our videos were getting hundreds of comments asking for a free playbook. Replying to each one by hand was impossible, and every comment we missed was a lost email sign-up. Off-the-shelf tools charge a monthly fee per contact, and they still miss the awkward cases: people who type the keyword differently, and people whose messages are closed.

Hundreds of comments, far too many to answer by hand.
People type the same keyword in many different ways.
Some people have messages from Pages switched off, so a DM fails.
Third-party tools charge per contact and lock you into their platform.
/ What we built

A system built around the real workflow

We built our own comment-to-DM bot on Meta's official API. When someone comments the keyword (for example "433") under a post on Instagram or Facebook, the bot sends them a private message with the link to the playbook page. It understands the different ways people type it ("4-3-3", "4:3:3", "1-4-3-3"). If someone's messages are closed, it replies publicly with the link instead, so nobody is left without an answer. It runs as a small cloud function and costs nothing per contact.

/ For your business

How your business could use this

1

Creators and brands with busy comments

Turn "send me the link" comments into email sign-ups automatically, without paying a per-contact fee.

2

Shops running promotions

Comment a word, get a discount code in your DMs. People engage with the post, which also helps the algorithm show it to more people.

3

Coaches, agencies and course sellers

Give away a guide or a free lesson in exchange for a comment, and send every lead straight into your email list or CRM.

/ Questions

Common questions

Is this allowed by Instagram and Facebook? +

Yes. It uses Meta's official API and the private reply feature Meta provides for exactly this purpose, from the brand's own Page.

What happens if someone's DMs are closed? +

The bot detects it and replies to the comment publicly with the link instead, so the person still gets it.

Why not just use ManyChat? +

You can. A custom bot has no per-contact fee, handles spelling variations and edge cases you choose, and plugs straight into your own database and email list.
