From a short brief to an on-brand draft, in minutes.

So, you're curious how it works. Good. Here's the tour: the mechanism (just the fun part, not the secrets behind it), two real examples of it running, and exactly how we get you live in about a month.

Every message says two things: the words, and the feeling behind them.

The feeling decides if it gets read. Lexi shows you both, the words and the feeling, before you hit send. Our psychologists and copywriters have been getting this right for 12 years. Now you can too, in seconds.

Psychology of persuasion

Copywriter

Turns a short brief into a draft that already sounds persuasive, not a blank page you have to fix five times.

Positive psychology

Supporter

Reads the emotion behind a customer's message first, then drafts a reply built to calm it down, not just answer it.

Linguistic diagnostics

Analyzer

Scores a draft across four behavioral dimensions before it's sent, and flags exactly what to rewrite.

0real replies our psychologists and copywriters wrote by hand, over 12 years.
0specific psychological rules behind every draft, not just style preferences.
0real drafts, tested and corrected by human experts, to prove they actually work.

Most AI tools generate text. Lexi is built to generate behavior: what the reader believes, feels, and does next.

Not a model with a prompt.
A team behind every setup.

Real psychologists, copywriters, and prompt engineers set up every module for your brand. Nothing here is generic.

Psychologists decide which psychological principles fit your industry, audience, and brand.

Copywriters write and correct the texts that teach Lexi your Voicebook and Brandbook.

Prompt engineers turn all of it into a system that drafts in your voice, automatically.

So your Lexi ends up sounding like your brand, not like every other client's.

Watch real input become a finished text.

A brief, a customer message, or an email you already sent goes in, and a finished, on-brand text comes out. This is Lexi's actual interface, not a mockup.

    Send one you actually sent, and we'll show you the analysis and the rewrite.

    Book a demo

    You don't write anything new. We build it from what you already have.

    Send us what already exists: your brand materials, information about your department, and what you want Lexi to write. That's it, no new documents to draft.

    01

    About your brand

    You send us

    Brand guidelines, mission and vision, a bit of strategy.

    We build: your Brandbook
    02

    About your department

    You send us

    A quick description of your department, a few good and bad examples, any rules to follow.

    We build: your Department book
    03

    About the task

    You send us

    A couple of examples, and any format or language rules.

    We build: your Playbook

    Our writers, AI engineers, and programmers do the actual writing and building. No generic first draft to fix. No back and forth to get the tone right.

    Five steps, from your texts to a working draft.

    Once we have your three books, here's what happens on our side.

    01Collecting textsAs many of your real texts as possible, ideally around 20,000 words.
    02Extracting rulesQuantitative and qualitative analysis of how you actually write.
    03Adapting formatAny channel or format is possible: email, SMS, chat, and more.
    04Generating textDrafts follow the formats you've agreed on.
    05Your feedbackTypically two rounds, until drafts sound right.

    Three phases. About a month to production.

    Same process for every client, whichever modules you use. No custom one-offs, no surprises.

    Phase 1 · weeks 1–2

    Implementation

    You send around 30 real texts (roughly 20,000 words total), your brand guidelines, and any legal writing rules. Then we run the 5-step process above, typically with two rounds of your feedback.
