Instagram keyword automation
Instagram keyword automation:
one word in, the right DM out.
A keyword trigger sends a specific DM when a comment or message contains a word you chose. Good keywords are short, easy to type and specific to one offer.

Choosing keywords
- One word per offer, so you know what each comment wants.
- Easy to type on a phone: no punctuation or long phrases.
- Say it and show it in the Reel so people know what to comment.
- Add common misspellings and local-language versions as extra keywords.
- Use different keywords on different posts to see which content brings leads.
What can trigger a DM
| Trigger | What happens | Good to know |
|---|---|---|
| Comment keyword on a post or Reel | The commenter gets a private reply (DM) with your link, file or question. | Instagram allows one private reply per comment, within 7 days. |
| Story reply | A DM answers the reply. | Story automation starts on the Starter plan. |
| Story mention | A thank-you or offer is sent to the person who tagged you. | Story automation starts on the Starter plan. |
| Incoming DM | A keyword or flow answers the message. | Instagram's 24-hour messaging window applies after their message. |
What ReplyKaro includes
Comment-to-DM
Set a keyword on a post or Reel and send a link, file or question when someone comments it.
Story automation
Reply when someone answers your Story or mentions you in theirs.
Follow-Gate
Ask people to follow you before the link is sent. Included on every plan, including free.
Fan Mode

Flow Builder

Link tracking

Account health
Watch delivery and sending limits so you stay inside Meta's rules.
Avoid these mistakes
- Running two tools on the same post: Instagram allows one private reply per comment.
- Keywords so common that unrelated comments trigger the DM.
- Sending the same long message to everyone: add a question to start a real conversation.
How sending limits work
Instagram caps how many private replies an app can send each hour. ReplyKaro sends below that cap by default: 180 DMs an hour on the Free plan, 200 on Starter and up to 300 on Pro. If a Reel goes viral and comments arrive faster than that, they are queued and sent as capacity allows, as long as they are inside Instagram's 7-day window.
How ReplyKaro keeps your account within Meta's rules
- It connects with Instagram's official login. It never asks for your password and does not use bots or browser extensions.
- It only messages people who commented a keyword, replied to your Story, mentioned you or messaged you.
- It sends below Meta's hourly cap and queues the rest.
- You can pause any automation, and take over any chat yourself.
- No tool can guarantee an account will never be restricted. Keep messages relevant and avoid repeating identical text to large audiences.
