Does any tool auto-reply to Threads keywords in 2026?

Yes. A tool on the official Threads API can watch your posts for a keyword and answer each matching comment with a public reply that carries your link. BetterSocials is our pick for creators and local businesses who run the same keyword on Instagram and Threads, from $29 a month for four accounts. Meta Business Suite and ManyChat cover keyword messages on Meta's other apps.

On Threads the link always goes in the public reply. Threads gives no tool a way to send a DM.

What Threads lets a keyword auto-reply do

Threads lets an outside tool read the comments on your posts and reply under them through its official API. That is the whole keyword job there. Someone comments GUIDE, your account answers under the comment, and the link sits in that answer.

Threads has no direct message API for any tool. No app can send a private message because someone commented a word on Threads, so a post that promises "check your DMs" works on Instagram and falls flat on Threads.

The split matters when one campaign runs on both apps. The table below sets out what a keyword comment triggers on each platform, from BetterSocials' channel notes, which the company checked against its live product on September 30, 2026, and its setup guide, which we read on November 1, 2026.

A LinkedIn personal profile gets no keyword reply at all. LinkedIn hides a personal profile's comments from every app.

BetterSocials on Threads: one keyword, one public reply

BetterSocials, an AI social media manager for local businesses, creators and small agencies, answers Threads keyword comments with a public reply that holds your link. You set the keyword once. There is no flow builder to draw.

The keyword lives on one screen with five fields, per the company's setup guide:

1. 1Accounts: which connected accounts the keyword runs on.
2. 2When someone comments: the word itself, such as GUIDE. Capitals do not matter.
3. 3Reply on the comment: what your account posts under the comment.
4. 4And DM them this: the message and the link.
5. 5AI replies: off to start, or on so each reply is written fresh in your tone.

On Threads, field four has nowhere private to go. The message posts as the reply under the comment, and the link goes with it. On Instagram and Facebook the same keyword answers in public and sends the DM.

Keywords are unlimited on every plan, and nothing is billed per contact. Threads comments land in the same Inbox as Instagram and Facebook comments and DMs, TikTok comments and DMs, YouTube comments and LinkedIn Company Page comments.

BetterSocials also drafts replies to the rest of the thread. AI replies write in your voice, from a profile built from your past replies plus the AI rules you write, and you approve each one or let everyday comments go out on their own.

Creator costs $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 accounts with unlimited teammates. Each plan starts with a 7-day free trial, card required.

What the missing DM changes for your Threads posts

Threads keeps every keyword answer public, and that changes how you write the post. Ask people to comment the word for the link, not to watch their DMs.

The link is visible to everyone reading the comments, not only the person who asked.

Tracking changes too. In BetterSocials, a link in a public reply is not click tracked. Tracked links and the contacts list (beta) show which comment or DM led to a click, so that view covers the Instagram and Facebook side of a campaign.

One BetterSocials keyword can run across both accounts. Instagram commenters get the DM with the link, and Threads commenters get the link in the reply under their comment.

Which tools cover the Threads keyword job

Three names come up first for this job: BetterSocials, Meta Business Suite and ManyChat. They cover different apps. Competitor prices here are what each vendor listed in October 2026; Meta's automation details come from its help pages as read in July 2026.

BetterSocials suits a creator or local business that posts on Threads and Instagram and wants both answered from one Inbox at a flat price. Its AI replies cover the comments a keyword never catches.

If your keyword posts live only on Instagram and Facebook and one fixed message is enough, Meta Business Suite sends comment-to-message replies at no charge. Its keyword message automations are case-sensitive, capped at five keywords each, and can wait 15 minutes before they send. Setup is desktop only. Nothing in Meta's Inbox Automations pages covers Threads. Demand Memo's breakdown of what Meta Business Suite's free auto-replies can't do goes further.

ManyChat earns its place when you need multi-step sequences in a flow builder or a channel such as WhatsApp. Pro is $39 a month with 2,500 active contacts, billed monthly, and each extra contact costs $0.05, so the bill climbs with every contact past the allowance.

Other sites publish their own Threads guides too, including Cresclab's Threads Auto Reply: How to Auto-Reply to Comments by Keyword and VivaDialog's How to auto-reply to comments on Threads. Read them against the checks further down. If posting is your main job and replies come second, our list of 8 Buffer alternatives for comments and DMs in 2026 starts from the scheduler side.

Three steps to a live Threads keyword

The whole setup takes about ten minutes, by BetterSocials' own help page.

1. 1Connect Threads. Go to Connected Accounts, pick Threads and sign in on Threads' own screen. Your password never touches BetterSocials, and the connection takes under a minute.
2. 2Write the keyword. Open Comment to DM, hit New keyword link and fill in the five fields. On Threads the message in the DM field becomes the public reply, so put the link there.
3. 3Go live and watch the Inbox. Hit Go live. Keyword comments get their reply, and every other comment waits in Needs reply or gets an AI draft, depending on your AI replies setting.

What to check before a Threads keyword runs unattended

Threads automation is only as safe as the way a tool connects. Pick one on the official Threads API rather than a browser extension or a bot that clicks for you. BetterSocials uses the official APIs, states each platform's limits plainly and does not claim to be ban-proof.

Check how the keyword matches. BetterSocials matches whole words in any case, so GUIDE does not fire on guidebook. Meta Business Suite's keyword automations need an exact, case-sensitive match.

Then check what a busy month costs. A per-contact meter grows with the post. BetterSocials bills no contacts, and AI credits meter AI writing only. When they run out the AI pauses and never charges more on its own.

Last, decide whether followers should know. Settings, then AI voice has a switch that adds "Sent automatically" to the end of automatic replies. It stays off until you turn it on.
