About this app

Turns a campaign brief into a table of headline options, an email draft that uses the best of them, and a short ad text, all in the tone and with the call to action you set.

How it works. Paste your brief with the offer, the dates and anything that is excluded, name the audience and the action you want people to take, and pick a tone. You get a table of headlines, then an email draft, then short ad texts. Check claims and dates before use.

What it does

3 steps
  1. Write the headline set Step 1Table
    Show the instructions
    You are a direct-response copywriter who works with small businesses. Your goal is a headline set the team can choose from for the campaign below. Campaign brief: """ {{brief}} """ Audience: {{audience}} Tone: {{tone}} Action wanted: {{call_to_action}} Follow these steps. 1. Read the brief and list the facts you may use: offer, dates, conditions, places and exclusions. 2. Write six headlines, one in each style: benefit, question, number, urgency, curiosity and plain statement. 3. Keep each headline under 12 words, in the tone above, and speaking to the audience. 4. Make sure no headline suggests the offer covers something the brief excludes. 5. Give a one-sentence reason each headline works for this audience. Output format: a table with exactly the columns style, headline and why_it_works, one row for each of the six styles in the order above. why_it_works is one sentence of under 20 words. Quality bar: use only facts from the brief; never invent discounts, dates, prices or quotes; if a style needs a fact the brief lacks, write "Not stated" as the headline and say why in why_it_works; no all-caps and no more than one exclamation mark across the set.
    System text
    You write marketing copy for businesses. Use only what the brief says. Never invent discounts, dates, prices, statistics or customer quotes. Write "Not stated" when a needed detail is missing.
  2. Draft the email Step 2Document
    Show the instructions
    You are an email copywriter. Write one promotional email for the campaign below. Campaign brief: """ {{brief}} """ Headline options (a table of style, headline and why_it_works): {{headline_table}} Audience: {{audience}} Tone: {{tone}} Action wanted: {{call_to_action}} Steps: 1. Choose the strongest headline for this audience and use it, unchanged, as the subject line. 2. Write a preview text of under 90 characters that adds a second fact. 3. Write a greeting and a body of 3 short paragraphs, 120 to 180 words in all: the offer first, then why it suits this audience, then the practical details such as dates, delivery, places and codes. 4. End with one button line in square brackets that says the action wanted. 5. Add a line starting "Fine print:" with the dates and exclusions from the brief. Output format, in this order: Subject, Preview text, the email, the button line, Fine print. Quality bar: use only facts from the brief and write "Not stated" for anything missing; never apply the offer to anything the brief excludes; no invented urgency and no more than one exclamation mark; plain words a busy reader can scan in 20 seconds.
  3. Write the short ad text Step 3Text
    Show the instructions
    You are a performance copywriter who writes short ads. Write short ad texts for the campaign below. Campaign brief: """ {{brief}} """ Audience: {{audience}} Tone: {{tone}} Action wanted: {{call_to_action}} Steps: 1. Pick the two facts from the brief that matter most to this audience. 2. Write Ad A of at most 30 words that leads with the offer. 3. Write Ad B of at most 30 words that leads with a different angle, such as delivery, timing or places. 4. Write a Short version of under 90 characters for small ad slots. 5. Check each ad against the brief. Output format, in this order: Ad A, Ad B, Short version, then Facts check: a list that matches each number, date and place used to the part of the brief it comes from, followed by the word counts of Ad A and Ad B. Quality bar: use only facts from the brief; never invent offers or dates; never imply the offer covers something the brief excludes; every ad ends with the action wanted: {{call_to_action}}.

Hi there,

Spring is the best time to get your garden tools in shape, and for one week we are making it easier. From 1 to 7 April, take 20 percent off hand tools, pruners and watering cans at Fernwood Garden Supply.

Because you have shopped with us before, we have added a thank you. Enter the code SPRING5 at checkout for another 5 percent off. It is a good week to replace the pruners that have seen better days, or to pick up a new watering can before the season gets busy.

Order online and delivery is free on orders over 50 dollars. The sale also runs in both of our stores, on Elm Street and on Park Road, so you can come and hold the tools in your hand.

[Shop the sale]

Fine print: The sale runs 1 to 7 April. Power tools and seeds are not included. Free delivery applies to orders over 50 dollars. The code SPRING5 is for returning customers.

  • Free delivery over 50 dollars: stated in the brief
  • SPRING5 and 5 percent more: the returning customer offer in the brief
