What is the best free AI tool for small business social media?
A workable free stack is a free post and caption generator for writing, Canva for design, CapCut for video, and Buffer or Metricool's free tier for scheduling up to three channels. That covers a small business's whole workflow at no cost.

The free stack, in order
Start with writing, because that is the usual bottleneck, then add design, then scheduling. Adding all four at once is how small teams end up with tools they never open.
- Write: free post, caption, and hook generators
- Design: Canva free tier
- Video: CapCut free editor
- Schedule: Buffer or Metricool free tier
- Measure: platform analytics plus a free engagement calculator
When to spend the first money
Pay when a second person needs to approve content, when you pass three channels, or when reporting takes more than half an hour a month. Before then, the free stack is not a compromise.

More questions
Do AI social media tools actually work?
Yes, for a specific set of jobs: first drafts, format conversion, scheduling, clipping video, and summarising analytics. They do not work as a replacement for judgement about what to say, and output that goes out unedited usually underperforms.
Can AI run my social media for me?
Not completely. AI can draft, schedule, publish, clip, and report — roughly the mechanical two-thirds of the work. Deciding what to say, replying to real people, and judging when not to post still require a person.
Is AI-generated content penalised?
No. Google rewards helpful content regardless of how it was produced and penalises unhelpful content produced at scale. Social platforms require disclosure of realistic synthetic media but do not penalise AI-assisted writing or editing.
How much do AI social media tools cost?
Most paid plans land between $15 and $50 per month for one person or a small brand, $80 to $250 for a team, and $300 upward for agency or enterprise platforms. Usable free tiers exist for scheduling, design, and generation.
