Automatic public replies to Instagram comments

Answer comments where they happen. Repli posts a public reply under the comment that matches your rule — a fixed message, one of up to five rotating variations, or an AI-written reply — through Instagram’s official comment permissions.

Why teams choose Repli

What you get

Public reply, posted by Instagram’s API

The reply is published as a real comment reply through the Graph API, visible under the original comment like any manual reply.

Rotating variations

Add up to five reply texts per rule. Repli picks one at random for each comment, so a busy post does not show the same sentence fifty times.

Optional AI replies

Let AI write the reply from your prompt instead of a fixed text. AI comment replies are capped at 300 characters and do not use your DM conversation context.

Pairs with comment-to-DM

A public reply rule and a DM rule can both match the same comment — the commenter gets a public acknowledgment and the link or question in their inbox.

Use cases

Giveaway and launch posts

Acknowledge every entry comment publicly while the DM rule delivers the prize details.

FAQ-heavy posts

Answer “price?” and “link?” comments publicly so other readers see the answer too.

Engagement pods and reels

Keep reply velocity high on a viral reel without typing the same thanks under every comment.

Frequently asked questions

Is the reply public or a DM?

Public. It appears as a reply under the comment, posted through Instagram’s official comment reply endpoint. If you also want a DM, add a comment-to-DM rule — both can fire on the same comment.

Can I reply to every comment, not just keywords?

Yes. A reply-to-all rule matches every new comment; keyword rules match only comments containing your words.

How do the reply variations work?

You can save up to five reply texts on one rule. Each matching comment gets one of them at random, which keeps a busy comment section from looking automated.

What does the AI reply option do?

Instead of a fixed text, AI writes the reply from your instructions. AI comment replies are limited to 300 characters and do not read your DM history with that person.

Does this work with Comment Guard moderation?

Yes. Comments that pass your moderation rules can still trigger reply rules; hidden spam never gets a reply.

Which Instagram accounts can use it?

Any professional (business or creator) account connected to Repli with the official comment management permission.
