How to Auto-Reply to Instagram Comments

Set up automatic replies to Instagram comments — both public replies and DMs — so every commenter hears back instantly. A step-by-step guide.

By The Tendrify Team · · 5 min read

When a reel takes off, the comments pile up faster than you can answer. Auto-replies fix that: every comment gets a response — a public reply, a DM, or both — the moment it lands.

Two kinds of comment auto-reply

  • Public reply — a comment back under theirs, so everyone sees you engage (great for reach)
  • DM reply — a direct message with the link or next step, private and personal

Set up automatic comment replies

  1. 1Create a flow with a Comment trigger and pick the post (or all posts).
  2. 2Add keywords, or turn on 'any keyword' to reply to every comment.
  3. 3Write the public comment reply, the DM, or both.
  4. 4Turn the status on.

Keep your comments clean, too

While you're automating replies, turn on IG Shield to auto-hide spam, scam drop-links, and words you don't want under your posts — so your best content isn't buried in junk.

Vary your public replies so they don't look copy-pasted. A short, warm reply plus the real answer in the DM feels human and still scales.

Frequently asked questions

Can Instagram automatically reply to comments?

Not natively — you need a tool on the official API. Tendrify auto-replies to comments publicly, by DM, or both, based on keywords you set.

Should I reply publicly or by DM?

Both works best: a public reply boosts reach and shows you're active, while the DM delivers the link privately and opens a conversation.

Can I auto-reply to every comment?

Yes — enable 'any keyword' so every comment triggers a reply, with a cooldown so repeat commenters aren't spammed.
