Social schedulers, ad generators, content creators, AI assistant suites and publishing agents do very different jobs. We compare Buffer, AdCreative.ai, Holo, Sintra and Krealo Publisher on what they do, who they suit and what they cost to start.
The best AI marketing tool for a small business depends on the job you need done. If you want cheap, simple social scheduling, Buffer is hard to beat. If you want ad creatives at volume, AdCreative.ai is built for exactly that. If you want a low-cost all-round content generator, Holo starts at about $20 a month. If you want a general "AI team" for a founder, Sintra bundles 12 assistants. And if you want posts, SEO blogs and replies that are published for you after a human approves them, that is what Krealo Publisher does. Krealo Publisher is our own product, so we will be clear about where the others are the better choice.

The five types of AI marketing tools
"AI marketing tool" covers very different products. Before comparing prices, decide which of these jobs you are actually hiring software for:
- Social schedulers put your posts on a calendar and publish them to your channels. AI usually helps write captions.
- Ad creative generators produce banners, product photos, ad copy and short videos for paid campaigns.
- All-in-one content generators create posts, ads, blog drafts and emails from a description of your brand.
- AI assistant suites give you several chat-style "helpers" for marketing, support, sales and admin.
- Publishing agents write and publish content across social networks, your website blog and your Google presence, with a person approving each piece.

What each tool is better at
Buffer: the simple, affordable scheduler
Buffer charges per channel, which keeps costs low if you only run a few accounts. It connects to a long list of channels, including Instagram, Facebook, TikTok, LinkedIn, X, YouTube, Threads, Pinterest, Google Business Profile, Bluesky, Mastodon and Substack. There is a free plan and an AI assistant for writing. Its pricing page does not indicate that it writes SEO articles or publishes blogs to your website. If you already know what to post and just need it on a calendar, Buffer is a strong choice. More options: Buffer alternatives.
AdCreative.ai: built for paid ads
AdCreative.ai focuses on ad creatives, product photos, ad copy, UGC-style and AI videos, competitor insights and creative scoring. It works on credits, so check how many creatives you need each month before choosing a tier. It is a creative generator: its page does not indicate organic social publishing, blogs or Google Business Profile. If paid ads are your main channel, it is the specialist here. See AdCreative.ai alternatives.
Holo: lowest entry price for content creation
Holo builds your brand profile from your website URL, then generates ads, social posts, SEO/blog content and emails, including carousels, reels, UGC videos with avatars, variations and translations in 99+ languages. Integrations shown include Instagram, Facebook/Meta, LinkedIn, TikTok, Pinterest, Shopify, Slack, Gmail and WordPress. The Starter plan excludes Autopilot and Analytics; Scale ($48.33/month, or $19.33/month paying 6 months) adds them with 325 creations and 3 brands. For creative volume on a small budget, Holo is very competitive.
Sintra: an AI team for one price
Sintra gives you 12 helpers, from Soshie for social media and Seomi for SEO to Penn for copy, Emmie for email and Cassie for support, with 250 credits a month and 100+ languages. Seomi writes SEO articles and runs audits. Its pricing page does not mention scheduling or automatically publishing to social networks. It suits a founder who wants a broad assistant across many business tasks rather than a dedicated publishing system.
Krealo Publisher: content that actually goes live, with approval
Krealo Publisher is our own product. AI agents write captions and media, publish to 11+ platforms (Facebook, Instagram, LinkedIn, TikTok, Pinterest, X, YouTube and Google Business Profile), answer DMs and comments from one inbox, and use a company "Brain" so content stays on brand. Every post waits for a person to approve it. The Business plan ($299/month per company + $15/user) adds blog publishing to WordPress, Wix and Shopify, Google Analytics, Search Console, auto-blog and Google Merchant Center. Where it is weaker: it is more expensive than Buffer or Holo at entry, and it is not an ad creative studio like AdCreative.ai. Full details on the Krealo Publisher page.
How to choose in five minutes
- You already write your own posts: start with Buffer's free plan.
- You spend most of your budget on paid ads: test AdCreative.ai's 7-day trial.
- You need lots of creative content cheaply: look at Holo Starter or Scale.
- You want a general AI assistant for many tasks: Sintra's 12-month plan is the lowest monthly rate.
- You want social, blog and Google Business content written and published, with your approval: try Krealo Publisher's Free plan, then move to Pro or Business.
Also count the hidden costs: per-channel pricing grows with every account you add, credit-based plans can run out mid-month, and per-user fees add up as your team grows. For side-by-side breakdowns, visit our comparison hub.
FAQ
What is the cheapest AI marketing tool for a small business?
Among these five, Buffer and Krealo Publisher both have free plans. For paid plans, Buffer Essentials starts at $5/month per channel and Holo Starter at $8.13/month when you pay for 6 months.
Which AI marketing tools offer a free trial?
Buffer offers a 14-day trial on Essentials and Team, and AdCreative.ai offers a 7-day trial with 20 credits. Holo lists no free trial. Sintra mentions a 14-day money-back guarantee rather than a trial. Krealo Publisher has a Free plan instead of a trial.
Can one AI tool handle social media, ads and blogs?
Holo generates ads, social posts, blog content and emails. Krealo Publisher publishes social posts and, on Business, blogs to WordPress, Wix and Shopify, but it does not generate paid ad creatives. Most small businesses end up combining two tools.
Do AI marketing tools post without me checking?
It depends on the tool and settings. In Krealo Publisher, every post waits for a person's approval before it goes out. Buffer's Team plan includes approval workflows. Always review AI content before it represents your brand.
