"Friendly, confident, expert, human." Hand those four words to a freelancer and the draft that comes back could run on any B2B blog under any logo. Every voice guide we have read used those same adjectives, and we think writers skip them for that reason and go straight to the sample post at the bottom.. Nobody objected when they went into the brand book. They were pleasant, true and impossible to disagree with. In a guide made of adjectives, the writer found what the company hoped it sounded like. The writer found nothing in it about how long the company's sentences ran, where its jokes landed or which words it would never use.
Adobe made a version of this argument in an essay on why brand guidelines fail. Adobe argued that a directive like "Conversational, with clear authority" lands one way with a copywriter in Singapore and another way with an AI model writing product descriptions for a campaign in Brazil, because the guideline restated what the brand intended and left everyone downstream to guess at the rest. Adobe's answer was a full brand intelligence architecture, which is a lot of machinery for a small company about to hire its first freelancer. For that company, the cheaper fix already sits in the posts it has published.
A pasted paragraph carries its own rules
A real paragraph from a published post hands a writer three habits at once. Sentence length shows up as rhythm. The company's jokes stay where it first put them, and the words it avoids are missing without anyone writing a list. We think a written description of those habits takes several times the words a quoted passage needs to show them, and a writer handed the description still has room to argue.
On our own site we wrote "Docs rot." Two words and a full stop. No guide asking for "punchy, direct copy" would ever have produced it. Anyone who saw it learned in a second that fragments were allowed, that the verb did the work and that nobody here wrote "documentation can become outdated over time." A writer working from the adjective version would have produced that last sentence almost word for word.
Pick four passages from posts you would still sign
Start with the posts you would put your name to today. Anything written before a rename, a pivot or a change of mind about the market goes in a separate pile, since a writer copies whatever is in front of them, opinions included. Then pick one passage for each of four habits. Three to six sentences each is enough to carry a rhythm and short enough to read in passing.
The first passage shows how a post opens, so look for the opening that got to the point fastest, where the claim arrived before any warm-up about the state of the industry. After that comes a passage that shows how a number enters. Founders tend to drop figures too early, as bait, or too late, as decoration, and our own house rule is to bring a number in where the argument needs it, which means the passage to pick is one where that happened once and cleanly. Third comes the joke.
The fourth shows how the company disagrees with someone, and it is the one most guides leave out. For ours we would hand over the comparison page we wrote against AirOps. It called AirOps good, said which teams should go and buy it, and then explained who we were for. A writer who read it learned that we disagree by saying who fits where, and that sneering at the other side was off the table.
Write one rule under each passage
Under each passage goes a single line saying what it shows. One line per passage, one rule per line, written as plainly as a note to a colleague. We put the line "Revolutionary, apparently." on our site. Under it we would write that the joke goes at the industry's habit of overselling and leaves the reader alone.
The rule matters as much as the passage. Left alone with "Revolutionary, apparently," a reasonable writer could conclude that the house style ends sentences with "apparently," and the next draft would carry nine of them. The passage showed the sound. With the line underneath, the writer knew which part of the sound to copy, and that saved a round of edits nobody wanted to make.
Add one line you would cut today
For the fifth passage, go back to an old post you would no longer write. Quote the sentence as it went out, then write it again underneath the way the company would say it now. Suppose an early post opened with “We want to help teams do their best work.” In that case the rewrite might read "We built this for founders who answer the same question on six calls a week," and the gap between them teaches more than either line alone, because writers learn as much from the cut line as from the kept one. Side by side, the two lines show which way the voice moved, and no list of adjectives can show that, since an adjective names a quality and points nowhere.
This passage also caught a problem the other four missed. When we went looking for lines to cut on our own pages, the worst ones were the sentences that had sounded most professional when we wrote them. They had the right adjectives and nothing else.
Keep the guide to one page and swap passages quarterly
A brand book is right on the day someone writes it and rarely opened after that. Adobe's essay made the same case for large companies, warning that a static standard ends up enforcing rules that were correct two years earlier. One page is what a freelancer opens before a draft. Five passages, five rules, and a line at the top saying who the readers are fit on that page with room to spare.
Then swap the passages every quarter. Take out the two oldest and put in two from the latest posts you were happy with. That way the guide matches how the company sounded in its latest posts, and the freelancer you hired gets new openings to copy each quarter. Here the method has a limit. A rulebook can suck the life out of anything, and even a page of good passages goes stiff once a writer treats them as templates. From the passages, a freelancer picks up a voice. The next post still has to say something nobody at the company has said before, and no guide can supply that part.
Quote a recorded call while the blog is thin
If you have fewer than three published posts, you run out of material to quote. We hit this ourselves. When our blog started it had nothing in it, and the voice we had lived on the site's pages and in how we talked about the product.
The fix is to quote yourself from a recorded call where you explained the product well. We think a transcript catches a founder before anyone polished the words, and that is often closer to the voice than the homepage ever got. Trim the filler and the false starts, keep the order of the argument, and write the rule underneath the same way. Then strip out every customer name, company, budget and vendor that came up on the call. A voice guide travels to freelancers and tools, and none of that belongs in it.
Spoken passages have a limit too. People talking run long, repeat themselves and lean on "you know" in ways that look strange in a post. So treat the call quotes as placeholders. As each new post goes out, replace one transcript passage with a written one, and by the fourth or fifth post the guide should be built entirely from published work.
Propaganda builds the voice guide from published posts
We build the voice guide this way. We built Propaganda to read the posts a company has already published and write a one-page guide from them, with suggestions drawn from the edits its people keep making to drafts. The voice guide is in beta. Scheduled reorganizing of the rules, to merge them and loosen the ones that went stiff, is planned and not built yet. Until it ships, the quarterly swap stays a human job, and it takes about as long as reading your last few posts.
