Reel scheduling and keyword DMs in one app from $29 (2026)

One app can post your Reel and send the DM when someone comments the keyword in its caption, and on the prices we logged it costs less than pairing a scheduler with a DM tool. Our pick is BetterSocials, an AI social media manager for local businesses, creators and small agencies, at $29 a month for four accounts. Hootsuite pairs publishing with an inbox at a per-user price built for teams. ManyChat sends the DM well and leaves the posting to another tool.

What two tools cost against one subscription

In a two-tool setup ManyChat is the DM half, and ManyChat leaves posting to a separate tool, so you still pay for a scheduler. We logged the competitor prices here in October 2026; Buffer's comes from a November 2026 listing.

ManyChat Pro is $39 a month with 2,500 active contacts, billed monthly. Add Buffer at $5 per channel, billed yearly, for four channels. The pair runs $39 + 4 x $5 = $59 a month.

BetterSocials Creator covers the same four accounts for $29 a month, with both halves under one login. That is $30 a month less than the pair ($59 - $29 = $30). It is also one place to check instead of two.

Hootsuite puts publishing and an inbox in one app, at a price set per user. Its inbox starts on Standard at $99 per user a month, billed annually.

How BetterSocials posts the Reel and sends the DM

BetterSocials keeps the two halves on two screens of the same app. You build the Reel in Create Post, pick the Instagram account and set the time. In Comment to DM you write the keyword once, with the public reply and the DM that carries your link.

When someone comments the word, your account answers under the comment and the link lands in their DMs. Capitals don't matter, so "guide" and "GUIDE" both count. The keyword runs on every post for the accounts you pick, so the next Reel with the same call to action needs no new setup.

Instagram and Facebook get both the public reply and the DM. On TikTok, YouTube, Threads and LinkedIn Company Pages, the keyword posts a public reply with the link instead.

Then there are the comments the keyword misses: the questions, the objections, the brand inquiries. BetterSocials answers those with AI replies in your voice, for comments and DMs alike. Each has three settings: Off, Draft for me and Reply in my voice.

On Reply in my voice, a DM gets an answer about a minute after it arrives. Questions wait for you in Needs reply unless you switch on Answer questions too, and that switch only works once you have written at least one AI rule, such as your prices or your booking link. Each AI reply uses 1 AI credit, and Creator includes 1,000 a month.

Monthly bill by setup

Both setups here post and send the keyword DM: BetterSocials, and Buffer paired with ManyChat. Price is where they split. The table uses four accounts where a vendor prices by account or channel.

BetterSocials is best for one person or a small business that wants both halves under one login, with unlimited contacts and no per-contact bill.

Hootsuite is priced for teams. Its $99 is where the inbox starts, on Standard, per user and billed annually.

The Buffer and ManyChat pair earns its extra cost when you need multi-step sequences in ManyChat's flow builder, or channels such as WhatsApp. It also means two bills on two billing periods.

What a viral Reel adds to a ManyChat bill

ManyChat bills by active contacts. Pro includes 2,500, and each extra contact costs $0.05 on Pro, billed monthly. Essential charges $0.10 per extra contact and Business $0.025.

Picture the good night. A Reel takes off and 3,000 new people comment the keyword while you sleep. If your list already sat at 2,500, that month's Pro bill is $39 + 3,000 x $0.05 = $189.

BetterSocials prices that night the same as a quiet one. Every plan has unlimited contacts, unlimited DMs and unlimited keyword automations, and nothing is billed per contact. AI credits meter AI writing only. When they run out, the AI pauses; it never charges more on its own.

A spike still has limits on every tool. Instagram routes DMs to non-followers into message requests, which is why a public reply under the comment matters. We covered that in Comment-to-DM with a public reply: 5 Instagram rules in 2026.

Meta Business Suite covers the DM half for free

Meta Business Suite includes a free comment-to-message automation that sends a message reply to comments on your posts that contain specific keywords or phrases. It costs $0 and covers Facebook and Instagram.

The limits are real, though:

• Setup is desktop only.
• It sends one fixed template you write, with no AI drafting.
• Each automation holds at most 5 keywords, and they are case-sensitive, so they must match exactly.
• A keyword reply can wait 15 minutes before it sends.

Meta's tool fits you if one keyword on Instagram or Facebook is the whole job and the same message suits every commenter. It stops at Meta's own apps, so YouTube comments stay outside it. For the wider set of Instagram's rules on this, see "Comment LINK and I'll DM you": Instagram's 2026 rules.

Setting up one Reel with a keyword DM, step by step

Instagram is the account to connect first, and in BetterSocials a keyword Reel takes three steps from there.

1. 1Connect the account. Open Connected Accounts in the sidebar, pick Instagram and sign in on Instagram's own screen. It takes under a minute, and your password never touches BetterSocials.
2. 2Write the keyword and its DM. Go to Comment to DM and hit New keyword link. Fill in the accounts, the word, the public reply and the DM with your link, leave AI replies off to start, and hit Go live.
3. 3Schedule the Reel. In Create Post, pick Reel, put "Comment GUIDE" in the caption and set the time.

Every plan starts with a 7-day free trial, card required. The first paid charge carries a 30-day money-back guarantee.
