Is there one tool for AI captions and scheduling?

Yes, several tools write captions with AI and schedule posts from the same dashboard, and as of October 2026 their plans run from a free tier to $199 a seat a month. BetterSocials is best for a business whose posts bring back comments and DMs, from $29 a month for four accounts. Buffer is best for the lowest price per account, and SocialBee for five profiles with unlimited AI writing.

Captions and scheduling in one place: the cost view

BetterSocials, Later, SocialBee, Metricool and Sendible all put AI writing next to a posting calendar. So the yes is easy. We took the cost question instead: what each plan charges for the same number of accounts, with prices as of October 2026.

The prices only tell half of it. What splits these tools is what happens after the post goes live, when the comments and DMs come back. A caption writer saves you an evening, and the inbox decides whether the people who comment ever hear from you.

Which AI tools write captions and schedule posts in 2026?

BetterSocials sits first in the table below because it covers the most after the post goes live. The table lists each tool's AI caption feature, the price we saw and what its inbox covers, as of October 2026, sorted by how much of the reply side each one handles.

Hootsuite's $99 is per user a month, billed annually, and it's the tier where the inbox starts. Later's inbox needs Growth, which is $37.50 a month billed yearly. Metricool's free plan includes 5 AI credits per brand each month, and its paid tiers raise that to 20 and then 35.

Two more tools pair AI captions with an inbox. Sendible Core includes unlimited users, unlimited scheduling and unlimited AI credits for captions, in one workspace with six social profiles. Agorapulse lists an AI Writing Assistant in its composer and AI reply suggestions in its all-in-one inbox.

SocialBee says it plainly on its site: every plan includes unlimited AI content generation. That makes it a good pick if you write a lot of posts and rarely answer replies inside the tool.

Does Buffer's AI Assistant write captions?

Buffer bills per channel, at $5 a channel a month on annual billing, as of October 2026. Four channels come to 4 x $5 = $20 a month, and each account after that adds another $5.

That's cheaper than BetterSocials at the same count. BetterSocials Creator is $29 a month, or $24 billed yearly, for four accounts. The extra buys the DM side of the inbox, AI replies in your voice and keyword comment-to-DM.

Buffer's inbox covers comments on your posts only. Instagram and Facebook DMs stay in the phone app. Pick Buffer if you mostly schedule posts and answer a few comments by hand.

Does Later have an AI caption writer?

Later has AI tools for captions and post ideas next to its scheduler, laid out on its AI social media tools page. Later Starter is $18.75 a month billed yearly, as of October 2026.

The catch is the reply side. Later's Conversations inbox starts on the Growth plan at $37.50 a month billed yearly. It has no YouTube or LinkedIn conversations, so comments on those platforms get answered somewhere else.

Pick Later if you want its scheduler and AI captions and don't need YouTube or LinkedIn replies in the same place.

What does each tool cost for four to six accounts?

BetterSocials Creator is $29 a month, or $24 a month billed yearly, for four accounts and one login. Buffer is cheaper at four, at 4 x $5 = $20 a month on annual billing.

At five accounts, Buffer comes to 5 x $5 = $25 a month on annual billing. SocialBee Bootstrap is $29 a month, or about $24 billed yearly, for five profiles and one user. Accelerate is $49 a month for ten profiles.

At six accounts, Buffer is 6 x $5 = $30 a month on annual billing. BetterSocials Pro is $49 a month, or $39 billed yearly, for six accounts, one login and analytics. Sendible Core also comes with six social profiles in its one workspace.

Per-seat tools cost more once a second person logs in. Hootsuite puts its inbox on Standard at $99 per user a month, and Sprout Social puts its inbox on Standard at $199 per seat a month, both billed annually. So two people on Hootsuite Standard pay that $99 twice, close to two hundred dollars a month.

BetterSocials Team is $99 a month, or $79 billed yearly, for twelve accounts and unlimited teammates. Creator and Pro are one login each.

What happens to the comments after the post goes live?

Agorapulse and Metricool both pair scheduling with an inbox, and Buffer includes one that covers comments only. Hootsuite and Sprout Social keep theirs on higher tiers at per-seat prices. Later keeps Conversations on Growth.

BetterSocials puts every comment and DM from the connected accounts in one Inbox. That covers Instagram and Facebook comments and DMs, TikTok comments and DMs, and comments from YouTube, Threads and LinkedIn Company Pages. YouTube has no DM API for any tool, so YouTube is comments only.

Keyword comment-to-DM sends your link to the people who ask for it. A keyword in an Instagram or Facebook comment sends the person a DM with your link. On TikTok, YouTube, Threads and LinkedIn Company Pages, the keyword posts a public reply with the link instead.

Speed matters on Instagram. A business can only reply to a DM within 24 hours of the person's last message. If your comments bring in customers, the inbox should decide your pick more than the caption writer does.

How BetterSocials does this

BetterSocials starts with one post. You write it once and pick the platforms, then the AI drafts a caption for each one in your voice, plus a YouTube Shorts title. It can transcribe a video you upload and write the captions from what you said.

You edit or approve each caption, then schedule or publish to Instagram, Facebook, YouTube, Threads, LinkedIn and TikTok. Posting is unlimited on every plan, so batching a month ahead costs nothing extra.

The replies come back to the same Inbox. AI replies has two sections, Comments and DMs, and each has three settings: Off, Draft for me and Reply in my voice. Questions wait in Needs reply unless you turn on Answer questions too, which needs at least one AI rule with your prices, hours or booking link.

Caption writing and AI replies use AI credits. Creator includes 1,000 a month, Pro 2,000 and Team 4,000 shared. When the credits run out, the AI pauses and never charges more on its own.

Every plan starts with a 7-day free trial, card required, and the first paid charge carries a 30-day money-back guarantee. The BetterSocials pricing page lists all three plans.
