Summarize with AI
Voice of customer copywriting means writing your website in the exact words your buyers use for their problem, not the words your team uses for the product. For an early-stage startup the best source is the sales calls you already recorded: pull the phrases buyers said before you pitched, count how many calls each one shows up in, and put the most common one in your hero.
This matters because you cannot hear your own homepage the way a stranger does. You know what every line means, so every vague line still makes sense to you. Your buyers have been telling you what to write on every call. The headline is usually already in the recordings, said by a buyer. Your job is to find it, not to invent it.
Project intelligence for the built world, and 40 calls that never say it
Picture a startup, used here as an example and not a client, that sells a punch list tool to general contractors with 20 to 200 people. A superintendent walks a finished floor and talks into his phone. He says things like drywall crack above the door in 4B, photo attached. The tool turns his voice notes and photos into a punch list, splits it by trade and sends each subcontractor only their items before he leaves the site.
The homepage headline reads Project intelligence for the built world. The subhead reads AI agents that keep every job on schedule. Under it sit two buttons of equal weight, Book a demo and See the platform.
Now open the folder of recorded discovery calls. There are 40 of them, with project managers and superintendents. Search the transcripts for the buyer side only. Punch list shows up on 37 of the 40 calls. Some version of typing it up at night shows up on 19, as in typing up the list after dinner or doing it on Sunday. Which sub owns this shows up on 15. The word intelligence, said by a buyer before the founder used it, shows up on none. Agent shows up twice, and both times it is a question, roughly whether this is one of those AI agent things.
So the page leads with two words no buyer ever chose, and leaves out the two phrases half of them used without being asked.
Why the founder can hear every call and still miss the line
The founder has been on every one of those calls. He says punch list himself on every demo. He has rewritten the hero twice, each time after someone said it should sound bigger. The calls still open the same way. The prospect asks what it actually does, and he spends the first ten minutes explaining the page.
He missed the line because on a call he is listening to answer, not to write down. When a superintendent says he types the list up after dinner, the founder hears a cue to show the voice notes feature. He does not hear a headline, because he already knows the product solves it. The buyer is describing the problem in the only words a stranger on the homepage would recognise, and those words go into a recording nobody replays.
This is the one idea behind the whole method. You know your product and nobody else does. The buyer knows the problem, and he has already named it for you.
Pain words, category words, and the words that are only yours
When you read buyer phrases, sort them into three piles. Pain words describe what goes wrong in the buyer's week: typing it up at night, chasing the electrician, which sub owns this. Category words are the nouns a buyer files you under: punch list app, punch list software. Your words are the ones only your team says: intelligence, built world, agents, platform.
Each pile has one place on the page. Pain words go in the headline, because they make the right reader stop and think that is me. Category words go in the subhead or a small line above the headline, because they tell the reader which drawer you belong in. Your words go below the fold or nowhere. A buyer who has never said intelligence will not search for it, and will not recognise himself in it.
The Sawdust case study shows the same move on a music licensing site. Its buyers are brands, and the trade has plenty of insider terms: master recording, sync license, performer rights. The challenge on the page is written from the brand's side instead, where one signature quietly turns into seven before a brand can use a single note. The line a buyer reads first describes what the buyer lives through.
Most advice gets two things wrong
First, most voice of customer advice tells you to run a survey or book interviews. Those work, and a Copyhackers guide to copywriting research rates customer interviews as one of the best sources of unfiltered language that can go into copy verbatim. But a seed-stage founder already has something better and cheaper. A discovery call is the one place a buyer describes the problem before he has learned your vocabulary. A survey asks him to answer in yours.
Second, do not ask an AI tool to summarise your calls. A summary is a paraphrase, and a paraphrase turns typing it up at night into reduces administrative burden. That is the exact translation you are trying to undo. The model is useful for finding phrases across 40 transcripts in minutes. It is a poor judge of which words to keep, because it smooths language toward the average, and the average is the category jargon you started with.
One more claim worth arguing: pick the phrase buyers said most, not the one that sounds best. A line that showed up on 19 calls is a fact about your market. A clever line you wrote is a guess. Buyer phrases are often a little rough, and that is fine. The people who pay have said them out loud.
Mining 20 calls for your headline this week
You need 15 to 20 recorded first calls, a spreadsheet and an afternoon. Use first calls only. By the second call the buyer has seen your demo and starts repeating your words back to you.
- Strip names first. Remove the buyer's name, company and anything about their own customers before a transcript goes into any tool. See the privacy section below.
- Run one extraction prompt per call. Something like: list every phrase the prospect used to describe the problem, copied exactly, with the timestamp. Do not paraphrase. Do not summarise. Skip anything said after our side started describing the product.
- Check every phrase by hand. Search the transcript for the exact string. If it is not there, delete it. Models quietly tidy up phrasing, and a tidied phrase is no longer the buyer's.
- Tally in one sheet. Columns: phrase, number of calls it appears in, said before or after your pitch, buyer's role, and pile (pain, category, outcome, objection, yours). Group close variants, like typing it up and writing it up, under one row.
- Sort by number of calls. Ignore anything that showed up once, however vivid. Look hard at the top five pain rows and the top two category rows.
- Search your homepage for each top phrase. Count how many appear in the first screen. Zero is common. That number is your before score.
Mapping the phrases onto the hero, subhead and FAQ
Each pile from the sheet has a slot. For the punch list example, the rewrite reads like this.
- Headline. Before: Project intelligence for the built world. After: Stop typing up punch lists at night. This is the top pain phrase, almost unchanged.
- Subhead. Before: AI agents that keep every job on schedule. After: Punch list software for general contractors. Walk the floor, talk, and every item goes to the right sub with its photo before you leave the site. The category word comes first, then the second pain phrase.
- Main button. Before: Book a demo and See the platform, equal weight. After: one button, Try it on your next walkthrough, with the demo as a text link.
- FAQ. The objections pile becomes the questions, in the buyer's order of frequency: Do my subs need to download an app? Does it work in a basement with no signal? Can I still export the list to PDF for the owner?
Our guide to SaaS hero section design covers what the visual and buttons need to do once the words are right. If your buyer is not technical and your product is, the jargon audit for technical products is a good second pass over everything below the hero.
Testing the rewrite before you trust it
At seed stage you rarely have the traffic for a clean A/B test, so test with the people who matter instead.
Show the new first screen to five people who match your buyer and have never seen the product, for a few seconds each. Ask what it does and who it is for. If they answer in the buyer's phrase, it works. Our five second test for a homepage has the full script. Then watch your next ten first calls. If they stop opening with what does it actually do and start with rollout or pricing, the page is doing the explaining.
The cost of skipping this is easy to see for a sales-led company. The site's only job is booking the right calls, and every call that opens with ten minutes of translation is founder time spent on the homepage's job. Across all sectors the median gap from seed to Series A is around 616 days, and roughly 70 percent of seed companies never raise a Series A. Weeks of explaining your own headline come out of that window. If you would rather have a studio run this, our website design service starts from the page a stranger sees.
Keeping the call data private while you mine it
Call recordings hold more than buyer language. They hold names, prices, internal politics and sometimes details about the buyer's own customers. Treat the transcripts as confidential, even when you only want five words from each.
- Remove names, company names and numbers before pasting a transcript into any AI tool, and use a tool your company already has a data agreement with.
- Check that the calls were recorded with consent. Recording laws differ by state and country, so if you are unsure, ask whoever set up your call recorder.
- Never put an identifiable quote on the site without written permission. A phrase that 19 buyers used belongs to the market, not to one person. A full sentence from one named buyer is a testimonial, and it needs their yes.
Studio Maydit works with AI founders whose buyers describe the product better on a call than the homepage does. We design and build websites in Framer, Webflow and custom code, and a website project runs as a fixed scope in three to four weeks. If your hero says something none of your buyers have ever said out loud, book a call and bring three of your call recordings.
