What is a shelf talker?

A shelf talker is a small sign — typically a clip-on card, a mini case-card, or similar shelf-edge signage — that sits directly on the shelf lip or fixture next to a product, read in under a second as a shopper's eye scans past. This skill writes the actual short, punchy copy for that narrow format: a headline, at most one supporting line, sized and legibility-checked for real shelf-edge viewing distance.

How is this different from the In-Store Display & POS Brief and Endcap & Secondary Display Sell-In Brief skills?

The In-Store Display & POS Brief covers larger-format point-of-sale materials — free-standing displays, shelf-ends, coolers — with more room for a message hierarchy and an offer. The Endcap & Secondary Display Sell-In Brief is the pitch used to win a secondary placement in the first place. This skill is narrower than both: it assumes you already have shelf presence and writes only the small-format, shelf-edge messaging content itself — the actual words on a talker or case-card, sized for a few square inches, not the sell-in pitch or a larger display's full brief.

Which AI models does this prompt work with?

Any capable chat model — ChatGPT, Claude, or Google Gemini. The prompt is model-agnostic, so paste it into a chat, save it as a Custom GPT, or store it as a reusable skill so every shelf talker or case-card your team requests follows the same tight, legibility-checked copy discipline.

How do I know if my copy is actually short enough?

The skill character-counts the final headline and supporting line and runs a legibility check against realistic shelf-edge viewing distance and type size — but always test the actual print file at true size and mounting height before a full print run, since font weight, sign material, and store lighting all affect real-world readability in ways a character count alone can't fully predict.

Shelf Talker & At-Shelf Messaging Brief

Write the short, punchy copy for shelf talkers and small case-cards.

What is the Shelf Talker & At-Shelf Messaging Brief?

The Shelf Talker & At-Shelf Messaging Brief is a free AI skill that writes the actual messaging content for small shelf-edge signage — shelf talkers, mini case-cards, and similar narrow-format at-shelf signs. You give it the product, the retailer, the message goal, and the physical sign size; it returns 3-5 short copy directions sized to the format, a recommended headline and supporting line for the strongest direction, a legibility check against real shelf-edge viewing distance, and the mandatories a retailer typically requires on this format. It is built for shopper and trade marketing teams who need copy for a few square inches of signage, where a single wordy line goes unread from three feet away. Because it treats word count as a hard design constraint rather than an afterthought, the copy actually works at the size it will be printed and mounted. Live food and beverage shopper language data helps confirm the words shoppers actually respond to fit the space this format allows.

Who it's for

Brand managers briefing a printer on small at-shelf signage
Category teams adding call-outs for a new or repositioned item

What you get

3-5 short copy directions sized to the actual sign format
A recommended headline and supporting line for the strongest direction
A legibility check against real shelf-edge viewing distance
The mandatories a retailer typically requires on this format
Guidance on which claims fit and which need more space elsewhere
A print-ready copy block, character-counted

How to use it

1Paste the prompt into ChatGPT, Claude or Gemini.
2Fill the bracketed inputs (product, retailer, message goal, sign size).

Example input

Product: fictional 'Kettlewood' small-batch popcorn, new 'Smoked Maple' flavor. Retailer: a regional grocery chain. Message goal: flag the new flavor and give shoppers a reason to try it over the core Sea Salt SKU. Sign format: a 2x3.5 inch shelf-edge talker, standard clip-on style.

Example output

Shelf talker brief — Kettlewood Smoked Maple popcorn, 2x3.5 inch shelf-edge talker

Format read
A 2x3.5 inch clip-on talker is read from roughly 2-4 feet away in under a second, usually while a shopper's hand is already reaching toward the shelf. This size holds a headline, a short supporting line, and a small visual cue — not a paragraph, and not a full flavor description. Every word has to earn its place.

Copy directions

1. "NEW: Smoked Maple" / "Sweet meets smoky. Try it."
Direction: leads with newness (the biggest driver of a first look), then a 4-word flavor promise a shopper can taste-imagine instantly.

2. "Your Sea Salt favorite, leveled up." / "Introducing Smoked Maple."
Direction: bridges from the core SKU shoppers already trust, positioning the new flavor as a safe next step rather than a totally new risk.

3. "Smoked Maple is here." / "Small batch. Big flavor."
Direction: leans on the brand's small-batch identity as the reason to trust a new flavor, for shoppers who already know Kettlewood's positioning.

Recommended direction
Direction 1 — "NEW: Smoked Maple" / "Sweet meets smoky. Try it." This is the strongest pull for a shopper who has never noticed Kettlewood before: it leads with the newness cue that stops a scanning eye, states the flavor pairing in four words a shopper can mentally taste, and ends with a direct, low-effort action ("Try it") rather than a passive description.

Legibility check
At a typical 2-4 foot viewing distance, test the headline at minimum 24-28pt equivalent bold type and the supporting line at 14-16pt — anything smaller risks becoming unreadable at a normal walking pace past the shelf. If Kettlewood's brand font is a thin or script style, request a bold weight specifically for this format; brand fonts optimized for packaging often fail at shelf-talker size.

Mandatories
- "NEW" flag, if this is within the retailer's defined new-item window (confirm the exact window with the retailer, as most have one).
- Kettlewood logo, small, bottom corner — this format should be dominated by the message, not the logo.
- No price callout unless this talker is tied to a specific promotional price; if it's a pure awareness talker, leave pricing off entirely to avoid conflicting with the shelf tag.

What needs more space elsewhere
The smoked-maple flavor story (sourcing, process, why it tastes the way it does) does not fit here — that content belongs on secondary display copy, social, or the pack itself. This format's only job is to stop the eye and prompt the reach; resist the temptation to add a second supporting line beyond the one recommended above.

Print-ready copy block
Headline: NEW: SMOKED MAPLE
Supporting line: Sweet meets smoky. Try it.
Logo: Kettlewood (small, bottom right)
Character count: headline 17 characters, supporting line 27 characters — both comfortably within a standard 2x3.5 inch talker's legible copy budget.

Assumption to validate
This brief assumes the retailer's new-item flag window is still open for Smoked Maple — confirm the exact eligibility window with your category manager, since an expired "NEW" claim on a shelf talker is a common compliance flag at reset audits.

# Role
You are a shopper marketing copywriter who specializes in small-format, at-shelf signage. You treat word count as a hard design constraint, not a suggestion — you know a shelf talker is read in under a second from a few feet away, and every extra word is a word that goes unread.

# Context I'll provide
- Product: [PRODUCT — including if it's a new item or flavor]
- Retailer: [RETAILER]
- Message goal: [GOAL e.g. flag a new item, drive trade-up, explain a claim]
- Sign format and size: [FORMAT e.g. 2x3.5 inch clip-on talker, mini case-card]
- Existing brand voice or fonts (optional): [BRAND VOICE]

# Your task
1. If the product, message goal, or sign format is missing or vague, ask up to 3 clarifying questions BEFORE writing anything.
