Yes. A tool on the official Threads API can watch your posts for a keyword such as GUIDE and post a public reply under each matching comment, with your link in it. BetterSocials is our pick for creators, local businesses and small teams who run that play on Threads and Instagram together: it answers Threads keywords in public and sends a real DM for the same word on Instagram and Facebook, from $29 a month for four accounts. Meta Business Suite and ManyChat cover the Instagram half for free or by the contact.
A Threads keyword gets a public answer, never a DM
Threads lets an app on its official API read comments on your posts and reply to them. That is the whole automation: someone types your word, and your account answers under their comment.
What Threads does not give any app is a direct message. So on Threads the link travels in the reply, where everyone scrolling the thread can see it.
For a B2B team, that changes the offer you put in the post. A gated guide or a demo link works fine in public. A discount code meant for one person does not.
How BetterSocials handles a keyword comment on Threads
BetterSocials sets up a keyword on one screen with five fields, and there is no flow builder to draw. You pick the accounts it runs on, type the word, write the public reply, write the DM message, and choose whether the AI writes each reply fresh in your tone.
On Threads, the DM field has nowhere to go. BetterSocials posts your message as the reply under the comment instead, and the link goes there.
Capitals do not matter. Keywords are unlimited on every plan, and nothing is billed per contact.
The Threads comments land in the same inbox as your Instagram and Facebook comments and DMs, plus TikTok, YouTube and LinkedIn Company Page comments. Every new comment gets a tag when it arrives, such as Lead, Spam, Support or Comment to DM. A Lead is a comment asking about price, booking or availability, and a new one sends a push notification to your phone.
The comments that are not keyword hits can get an answer too. With AI replies set to Reply in my voice, BetterSocials answers everyday comments under the comment 1 to 5 minutes after they arrive, in a voice built from your past replies and the AI rules you write. Questions wait in Needs reply until you approve them, unless you switch on Answer questions too.
Threads has no DM API, so the link stays public
Meta gives no tool a Threads messaging API.
Instagram and Facebook work differently. A keyword comment there can trigger a private DM, and on Instagram, Meta allows one private reply per comment within 7 days of the comment.
BetterSocials runs one keyword across both. Instagram and Facebook commenters get a public reply plus a DM with the link, and Threads commenters get the link in the public reply.
TikTok, YouTube and LinkedIn Company Pages follow the Threads pattern. We covered the TikTok version in Auto-reply to TikTok comments with a link: 5 steps for 2026.
Threads keyword tools compared for 2026
Keyword comments get an answer from BetterSocials, Meta Business Suite and ManyChat, each on its own set of channels. ManyChat's price is the one on record in October 2026, billed monthly. Meta's figures come from its business help pages, read in July 2026.
| Tool | Channels | Keyword action | Price |
|---|---|---|---|
| BetterSocials | Threads, Instagram, Facebook, TikTok, YouTube, LinkedIn Pages | Public reply on Threads, DM on Instagram | $29 a month, 4 accounts |
| Meta Business Suite | Facebook, Instagram, Messenger, WhatsApp | Fixed template message | Free |
| ManyChat | Instagram, Messenger, WhatsApp, TikTok | Keyword or flow-builder trigger | $39 a month, 2,500 contacts |
BetterSocials fits a team that posts the same keyword call to action on Threads and Instagram and wants both answered from one inbox. The Threads reply and the Instagram DM come from one keyword.
If your audience lives only on Facebook and Instagram, Meta Business Suite costs nothing. Its keyword automations take up to 5 keywords each, match them case-sensitively, and can wait 15 minutes before sending, per Meta's help page. Meta's Inbox Automations pages do not cover Threads. We went through the rest in What Meta Business Suite's free auto-replies can't do.
ManyChat earns its price when you need multi-step sequences in its flow builder, or WhatsApp next to Instagram. ManyChat bills by active contacts: Pro covers 2,500, and each extra one costs $0.05.
Four steps to run a Threads keyword post
In BetterSocials, the setup runs in this order.
- Connect Threads. Go to Connected Accounts, pick Threads and sign in on Threads' own screen. Connecting takes under a minute, and your password never touches BetterSocials.
- Write the keyword. Open Comment to DM, choose New keyword link, type the word you will use in the post, and write the reply with your link in it. Pin it to Threads alone or run it across Instagram as well.
- Go live and post. Press Go live, then publish the post with the keyword in the call to action. Matching comments get the reply while you work on the next post.
- Count the comments, not the clicks. A link in a public reply is not click tracked in BetterSocials. Your measure on Threads is the number of keyword comments in the inbox, and on Instagram the DMs sent.
Our assumption is that a B2B offer, such as a guide or a webinar seat, reads fine as a public link. If yours needs privacy, run the call to action on Instagram, where the DM carries it.
Setup takes about ten minutes in total.
What to check before a Threads auto-reply runs unattended
BetterSocials uses the official APIs and states each platform's limits plainly, and that is the first thing to check in any tool. A browser extension or a bot that clicks for you works outside that API.
Second, check how the keyword matches. BetterSocials matches whole words in any case, so GUIDE does not fire on guidebook.
Third, check what a busy week costs. BetterSocials stays at one flat plan price however many people comment, because nothing is billed per contact. On ManyChat Pro, each active contact past 2,500 adds $0.05 to that month's bill.
Last, check what you can clean up. In BetterSocials you can hide a Threads comment from the inbox, one comment at a time, and the person who wrote it still sees it. Threads does not let you delete other people's comments through BetterSocials.
FAQ
Is there a tool that auto-replies when someone comments a keyword on Threads?
Yes. BetterSocials posts a public reply under any Threads comment that contains your keyword, with your link in it. You write the keyword and the reply once, with no flow builder. Plans start at $29 a month for four accounts, with unlimited keywords.
Can a Threads keyword comment trigger a DM?
No. Threads gives no tool a DM API, so no app can send a private message when someone comments a keyword there. The link goes in the public reply under the comment instead. On Instagram and Facebook, the same keyword in BetterSocials sends a real DM with the link and posts a public reply.
Does Instagram comment automation work on Threads too?
No, they are separate. A keyword automation on Instagram sends a DM, while Threads only allows a public reply. In BetterSocials you can run one keyword across both accounts: Instagram commenters get the DM and Threads commenters get the link in a reply.
Can I reply to Threads comments with AI in my own voice?
Yes. BetterSocials drafts replies to Threads comments in your voice, from a profile built from your past replies and the AI rules you write. You can approve each draft, or set Reply in my voice so everyday comments get answered 1 to 5 minutes after they arrive.
How much does a Threads auto-reply tool cost?
BetterSocials Creator is $29 a month for four social accounts and 1,000 AI credits. Pro is $49 a month for six accounts, and Team is $99 a month for twelve. Every plan has unlimited keywords and contacts, and nothing is billed per contact.
Is it safe to automate Threads replies?
Use a tool on the official Threads API rather than a browser extension or a bot that clicks for you. BetterSocials uses the official APIs and states each platform's limits plainly. Its keywords match whole words in any case, so GUIDE does not fire on guidebook.
