The Social Hub plans and publishes posts, builds paid ads and lead forms on Meta and LinkedIn, and boosts published posts from your own ad account.

How to choose

Start with the job, not the label. B2B marketing work splits into a few jobs: writing long content and campaign copy, getting leads and following them up, making visuals and video for LinkedIn and ads, and running social and paid channels. Most AI tools are strong at one of these, so name the job that takes most of your week and shortlist for that.

If your team is large and brand control is the problem, look at Jasper or Anyword: both keep brand voices and audiences in one place, and Anyword scores copy before it goes live. If sales and marketing share lead work, Copy.ai is built around account research and outreach. If your buyers ask AI assistants which vendor to pick, Writesonic is the only tool here that tracks those answers.

If you mostly need assets, look at what each tool makes. HeyGen is the pick for presenter videos and translated demos. Infinall AI makes images, motion videos, copy and voiceovers from your saved brand, then runs LinkedIn, Meta and Google ads from the same place.

Check seat pricing early. Jasper, Sprout Social and HeyGen Business charge per seat, which adds up fast for a team of five. Try the free plan or trial with a real campaign brief, and judge the output you would actually publish.

What B2B teams need from an AI marketing tool

B2B marketing has long sales cycles, several people in each buying decision and a heavy reliance on LinkedIn, search and email. That shapes what a useful AI tool must do:

  • Keep a consistent brand voice across many writers and channels, so a whitepaper, a LinkedIn ad and a sales email sound like the same company.
  • Produce assets for professional channels: LinkedIn single image ads, short demo videos, slide decks and landing page copy.
  • Capture and follow up leads. In Infinall AI, lead forms run on Meta and LinkedIn, with up to 3 questions on LinkedIn and up to 15 on Meta.
  • Show what competitors are saying. Infinall's Ad Spy searches the ads a brand is running on Meta, Google and LinkedIn, with no daily limit on Free or Pro.
  • Pass security review. Anyword and Writesonic list SOC 2 and GDPR compliance, which larger B2B buyers often ask about.

Budget: what a small B2B team actually pays

Prices vary more than features. For a team of 3 people, per-seat tools multiply quickly: Jasper Pro is $59 per seat per month billed yearly, and Sprout Social Essentials is $79 per seat per month on annual billing. Copy.ai Chat is a flat $29 per month for 5 seats, and Anyword Data-Driven includes 3 seats at $99 per month billed monthly.

Infinall AI uses credits instead of seats. One credit is one US cent. Free gives 1,000 credits a month, and Pro gives 3,000 credits a month for $30 a month or $299 a year, after a $10 first month. Planning and publishing posts uses no credits; a live ad uses 2 credits a month, and Pro includes 2 free account connections, then 300 credits a month per extra account. Your ad budget is always charged by the ad platform to your own ad account.

Free plans and trials compared

Only two tools here clearly have a lasting free plan. Infinall AI gives 1,000 credits every month with no card, and Ad Spy searches cost no credits. HeyGen Free gives 3 watermarked videos per month. Copy.ai shows a Try for free button, but its pricing page does not show the limits.

The rest offer trials: Jasper and Writesonic give 7 days, Anyword gives 7 days limited to 2,500 words, and Sprout Social gives 30 days with no credit card. Plan your test before you start a short trial, so you judge real work rather than a demo prompt.

Where Infinall AI fits for B2B, and where it does not

Infinall AI suits founders, small B2B teams and agencies that want one place to make campaign assets and run them. You paste your website, Infinall AI reads up to 20 pages to build your Brand Brain, and every image, video and line of copy can use it. Infinall Chat can write documents and slide decks, and Quick research writes a cited report on a topic.

It is not a sales outreach tool like Copy.ai, it does not track AI search answers like Writesonic, and it does not make avatar presenter videos like HeyGen. Large enterprise teams that need admin governance across many brands may be better served by Jasper's Business plan.
