Everyone says their voice is "friendly and professional." This reads a site's actual copy and measures it: rhythm, formality, who it talks to, energy, the words it leans on. You get a profile you can hand to a writer or an AI, instead of a vibe.
The Brand Voice Extractor is a free tool that reads a website's existing copy and turns it into a usable brand-voice profile, measuring tone, rhythm, perspective, and signature words, then giving you a paste-ready prompt. It sends the URL to my server, which reads the live page once and forgets it, with no AI call and nothing stored.
Founders, in-house marketers, and agencies who need to document or reproduce a brand's voice, whether to brief a writer, keep a team consistent, or make an AI model write in the brand's actual tone instead of generic filler.
Rather than asking you to describe your voice, it measures the voice already present in real copy: formality, sentence length and cadence, point of view, energy, and the specific words and phrases the brand leans on. The output is a profile concrete enough that a writer or an AI can actually reproduce it, not a vague label like "friendly and professional."
A brand voice generator invents a voice from a brief. A tone checker only flags whether text matches a preset tone. An analyzer, which is what this tool is, measures the voice that already exists in your copy. It is the most useful when you want to capture and document a voice you already have rather than invent a new one.
Analyze your highest-signal copy first, homepage, key product pages, founder posts, ads, and emails, and skip legal text and boilerplate. Take the resulting profile and the paste-ready prompt, and use them to brief writers or to make ChatGPT or Claude write in your voice consistently.
A tool that reads a site's existing copy and measures its actual voice, tone, rhythm, perspective, and signature words, then outputs a profile you can hand to a writer or an AI.
It runs a deterministic analysis on the copy you give it, measuring formality, cadence, point of view, energy, and the words the brand leans on. No external AI call, no API key, nothing stored.
Yes. The tool produces a paste-ready prompt so ChatGPT or Claude can write in the measured voice consistently.
No. It is deterministic, the same copy produces the same profile every time.
Tone, formality, sentence rhythm, point of view, energy, and the specific signature words and phrases a brand uses.
Yes. Anyone who needs to document or reproduce a brand's voice can use the profile and prompt directly.
Send me your site and I'll help you build a usable voice profile your whole team can write from, part of the marketing work I do for founders and service businesses.
Measured from real linguistic signals in the page copy, not an AI guess. Nothing is stored; each read fetches the live page once.
