How it works

One messy sentence in. A whole campaign out.

Real people type "need bf content for ig, 30 percent off". Quarter4 understands it, says what it assumed, asks at most three questions and keeps working while you answer.

01 · Understand

Your words, your places

Platforms like "ig, tik tok, status", places like "Lagos", "the Gulf" or "West Africa", offers like "N5k off" and deadlines like "ends nov 30".

02 · Find the moments

Dates that matter to you

60+ curated events and official holidays for 100+ countries, ranked for your audience and niche. A Lagos sneaker shop gets Black Friday and Boxing Day, not Diwali.

03 · Plan

Every post has a job

Tease, warm up, early access, launch, last chance, thank you. Launch days always post. Email and WhatsApp stay capped so people do not unsubscribe.

04 · Create

Fits what you sell

15 niche profiles drive the angles, hooks and shot lists: outsole close-ups for sneakers, fabric in motion for dresses, headlight sweeps for cars.

05 · Stay current

What is happening today

Today's top searches per country, upcoming public holidays and what the world is reading, with sensitive topics flagged so your brand never newsjacks a tragedy.

06 · Sell

A page built around your product

Drop in photos, a phone turntable video or a 3D model. The page is art-directed from what you sell, with motion that follows the scroll.

The calendar

Every month has a reason to sell.

Computed by rule (Easter, Thanksgiving, Mother's Day) or verified tables (Ramadan, Eid, Lunar New Year, Diwali, Hanukkah), with a note where moon sighting can move a date. Plus live official holidays for 100+ countries.

Highlighted: high-impact shopping moments. This strip is generated from the same data the tools use.

The pages

Pages that do not look generated.

An art director picks the structure from the product: cinematic scenes for cars and gadgets, a split showcase for fashion and food, a product stage for shoes and beauty, editorial for courses and software. Fonts, navigation, buttons, countdown and FAQ style change per brand. Each page below is one tool call.

Live data

Timely, never tone-deaf.

whats_on checks today's searches per country, the public holidays coming up and what the world is reading. Topics about deaths, disasters, crime or politics are moved to "avoid".

Example: Nigeria, sneaker shop

Newcastle vs Evertonfits niche
ASUU strike talkssafe, low fit
Al-Nassr FCfits niche

Shape of a real response; topics change daily.

Holidays it caught

UK Boxing Day 2026moved to Mon 28 Dec
Nigeria Boxing DayMon 28 Dec
Eid al-Fitr 20279 Mar, ±1 day
Mothering Sunday 20277 Mar (UK, Nigeria)

Substitute days come from official holiday data, not guesses.

Honest by default

Built to sell without lying.

What Quarter4 never does

  • Invent reviews, results or stock counts
  • Show a "was" price you never charged
  • Run a countdown that resets
  • Use another brand's logo photos (filtered out)
  • Sell on remembrance days or around tragedies

What every brief includes

  • Ad and affiliate disclosure
  • AI-image labels where platforms require them
  • Licensed music reminders
  • Niche rules: APR for car finance, no cure claims for beauty, allergens for food
  • Photo credits on every page
