Introduction
Hi, and welcome back. In the previous episode we wrote work emails. Now we move to a more relaxed world: social media. We'll learn to create consistent captions and content: defining a brand voice, planning a week of content, and adapting one idea for several platforms.
Step 1: Why consistency matters
Have you ever seen an account that's very formal one day, full of slang the next, and then just photos with no caption the day after? It feels like it's run by different people. That's why a brand voice matters. It's your account's personality. The way it greets, tells stories, and invites people to buy should feel the same every day. The first benefit: the account is easy to recognize. Loyal customers can tell a post is from Sunset Coffee even before they see the account name. Second, the account feels trustworthy. A steady style gives the impression that the business is run seriously. Third, it saves time. Once the rules are clear, we don't have to decide on a style every time we write. The problem is that staying consistent is tiring, especially for Nadia, who manages accounts for several small businesses at once. Let's see how Claude helps her.
Step 2: Defining the brand voice from old captions
Nadia doesn't start with theory. She pastes Sunset Coffee's three most popular captions and asks Claude to analyze the writing style. Claude finds a pattern Nadia hadn't noticed before: a friendly you, short sentences, coffee and sunset emoji, signature words like after work, and the price and ordering method every time. To make it reusable, Nadia asks for the pattern to be condensed into a five-point guide she can paste into every prompt. Here's the guide. Point one: talk to the reader as you, friendly and warm, like a friend inviting you for afternoon coffee. Second, two or three short sentences, with the main point in the first one. People scroll fast. Third, two emoji at most, preferably coffee and sunset. Too many emoji actually make a caption look cluttered. Fourth, always mention the price and how to order. A great caption that doesn't tell people how to buy is wasted. Fifth, avoid exaggerated claims such as cheapest or best in Bandung. Besides being less believable, claims like that can be misleading. Save this guide. Every time she asks for a caption, Nadia pastes it at the start of the prompt, so the results feel like they're written by the same person.
Step 3: A one-week content calendar
Now let's put the guide to work. Nadia asks for an Instagram content calendar for next week's five working days, with a theme, visual idea, and short caption, as a table. Claude builds the calendar in the right panel as an Artifact. Monday is start-of-week energy, Tuesday meets the product, Thursday is behind the scenes, and Friday is the hamper promo. Nadia wants Wednesday to feature a customer testimonial, because real reviews are usually more convincing than promotion. Claude only changes the Wednesday row, and the other days stay the same. That's the beauty of an Artifact: work in table form that you can revise one part at a time. One note: testimonials must come from real customer reviews, with their permission. Never ask Claude to make up a testimonial. To picture it, here's Nadia's weekly workflow. On Monday morning, she asks Claude to build a five-day calendar for each client. On Monday midday, she asks for full captions for every day at once, still in the same conversation, so the brand voice guide carries over. Then all the drafts go to the business owner for approval. Never skip this step, because the owner knows the product best. Finally, the posts are scheduled for peak hours. Work that used to take days is now done in one morning, and Nadia can take on more clients.
Step 4: One idea, many platforms
The same content idea often goes to several platforms. On the Instagram feed, it's a two- or three-sentence caption with a photo, in a warm storytelling style. For TikTok or Reels, what you need is a fifteen-second video script with a hook that grabs attention in the first three seconds. For WhatsApp status, one sentence with the price is enough, because customers there already know Sunset Coffee. One prompt is all it takes: ask Claude for all three versions of one idea at once, with the brand voice guide at the start. Nadia saves time, and the style stays the same. Here's Nadia's prompt in Claude. The brand voice guide goes first, then the idea of a Friday afternoon cold brew promo, and a request for three versions for three platforms. Claude gives all three versions at once. The Instagram caption tells a story, the TikTok script has a hook and scene directions, and the WhatsApp status gets straight to the point. The style stays the same across all three: a friendly greeting, few emoji, and a call to order. But something's off. Where did fifty thousand come from? Nadia didn't put a price in the prompt, so Claude filled it in with a guess. Once the draft is ready, Nadia doesn't post it right away. She sends it to Laras on WhatsApp for approval. Laras likes the style, but spots a mistake immediately: cold brew is fifty-five thousand rupiah, not fifty thousand. Luckily, the draft hasn't been posted yet. Nadia fixes the price and schedules the post for Friday at four in the afternoon. Laras approves. The lesson: we must always provide prices and product facts, and the business owner keeps the final approval. Imagine if that caption had gone live. Customers order at fifty thousand, then feel let down when they're charged more. One approval message protects your customers' trust.
Step 5: Caption templates and checks before posting
Now let's sum it up as a template. The first block holds the five-point brand voice guide. This is what keeps every caption feeling uniform. The task block names the content idea and the platform, for example a hamper promo for WhatsApp status. The data block holds the product name, price, and how to order. After what just happened, we know this block must never be empty. The format block asks for two caption options and five hashtags relevant to your city. Local hashtags like Bandung coffee help nearby buyers find you. Nadia can use this template for all her clients. She just swaps in each brand voice guide and the product data. Finally, check before posting. First, prices, product names, and opening hours. A wrong price on social media can disappoint customers when they order. Second, make sure there's a clear call to action: send a DM, order on WhatsApp, or tap the link in bio. Third, hashtags that are relevant and just enough. Hashtags unrelated to the product make the account look careless. Fourth, no exaggerated claims and no made-up testimonials. Customer trust is worth far more than one popular post. Fifth, any photos and reviews you use must be your own or used with permission. The Claude screens in this video are simulations, so menu positions may differ slightly on your screen.
Done!
We've defined a brand voice from old captions, built a content calendar as an Artifact, adapted one idea for three platforms, and saved a caption template along with checks before posting. In the next episode we write product descriptions that sell, for online stores, catalogs, and marketplaces alike. See you there!
