Ads that think. Brands that grow.

Brain Smart is building a team of AI agents that plans, writes and designs your ads — so small businesses can market like the big ones.

Animated preview: five AI agents turn a fictional bakery’s one-line brief into a strategy, ad copy, banners, a short-form video script and a final review.

The problem

Great small businesses deserve great ads.

Small brands compete in the same feeds as global giants — without a marketing team behind them.

  • No one to make the ads

    Owners already run the shop, the books and the team. Writing, designing and testing ads every week is one job too many.

  • Agencies cost too much

    Professional help is priced for big budgets and moves at agency speed — weeks, not hours.

  • Feeds burn through creative

    Social and short-form channels reward fresh creative. The ad that worked last month quietly stops working.

How it works

Your brief in. A campaign out.

Tell us about your business in a sentence or two. A team of specialized AI agents will do the rest — and you stay in control.

  1. Share a brief

    What you sell, who it’s for and where you want to show up. Links and photos welcome.

  2. The agent team gets to work

    Specialized agents plan, write, design and script — checking each other’s work along the way.

  3. Review and launch

    You approve every piece before it goes live, and can change anything with a sentence.

    Finds your audience and the angle that will move them.

  • Copywriter

What it creates

Everything a campaign needs.

Headlines, captions and calls to action

  • “Fall, freshly baked at 7 a.m.”
  • “Your commute just got a pumpkin-spiced upgrade.”
  • “Warm from the oven. Gone by noon. Come early.”

#pumpkinbread #morningcrumb #freshbaked

Image ads for every placement

Sized for feed and story placements on Instagram, Facebook and Naver.

15-second script with shot list

  1. 0–3s Oven door opens. On-screen text: “7:00 a.m.”
  2. 3–9s A knife slides through the first warm slice. Voice-over: “Fall is back.”
  3. 9–15s Map pin and a line at the door. On-screen text: “Morning Crumb · Gone by noon.”

Ready for Reels, Shorts and TikTok.

Who to reach, where, and what to test

Audience
Commuters aged 25–40 within 2 km of the shop
Channels
Instagram Reels and Naver local search
Test
“Freshness” vs. “limited batch” — two variants each

Every campaign is designed to include an A/B testing plan.

Sample output for a fictional brand, Morning Crumb Bakery.

Why now

The tools finally caught up with the problem.

  • Agents can do the work

    AI has moved beyond answering questions to carrying out multi-step creative work: planning, drafting, checking and revising.

  • Creative is cheap to make

    A new headline, image or script now takes seconds, not studio days. Volume is no longer the bottleneck.

  • Spend moved to feeds

    Advertising keeps shifting to social, search and short-form video — channels that reward a constant flow of fresh creative.

Team

Why we started Brain Smart.

Some of the best businesses we know are small: the bakery that sells out by noon, the studio with loyal regulars, the online shop run from a spare room. They make great things, but their ads rarely show it.

Big brands have whole teams for strategy, copy, design and video. Small businesses have an owner with no time left. We believe AI agents can finally close that gap.

We are building Brain Smart so that every small business can have a world-class marketing team on its side. If that sounds like a future worth building, we would love to hear from you.
