A generic answer frustrates.
So does ignoring how they feel.
That happens to agents too, not just clients. Every single answer either builds trust or breaks it, there's no neutral reply.
Three steps,
same flow every time.
Enter the key information
Write down what matters, or start from a template. Paste in the client's message underneath.
Supporter recognizes the emotion
It reads the tone behind the client's message and adapts the answer accordingly, calmer where it needs to calm, direct where it needs to be direct.
Supporter writes out the answer
Text that sounds natural, not templated, and addresses exactly what the client needs.
Why does Supporter sound like it was written by experienced psychologists and writers?
Because it was. Psychologists who study attention and persuasion have been writing these replies for twelve years, 11,500+ texts and counting. Our AI engineers deconstructed that work and put it into Lexi. That's why Lexi uses AI, but doesn't sound like AI.
Same complaint. Same information.
Different answer.

Supporter is for customer replies.
For other jobs, it's a different tool.
See Copywriter
Your marketing team needs an email out in ten minutes, and the last three drafts all sound the same. Copywriter learned from 11,500+ texts written by real copywriters and psychologists, so what it writes sounds like a person, and says exactly what gets someone to act.

You hit send, and only after does it hit you that the email sounded stiff, off-brand, or a little robotic. Analyzer catches that before you send anything, and tells you exactly what to fix.

Do I need to know how to write prompts?
No. You enter the key information and paste in the client's message, in plain language, no prompt engineering skill required.
Will it actually sound like our brand, not generic AI?
Yes. During setup, we train Supporter on your existing brand materials and writing rules. If you don't have a documented tone of voice yet, we also offer Voicebook, a separate, optional service where our team defines it for you and builds it into Supporter.
How long until we're live?
About a month from kickoff, once we agree to start working together, 4–6 weeks for heavily regulated clients like banks. Timing depends mostly on how fast your feedback comes back. Every user gets a one-hour onboarding session.
What languages does it write in?
Any language you need. The psychology behind a calming, empathetic reply doesn't change with the language, and we already write for clients in Croatian, English, and Serbian today.
Is our data used to train other companies' Lexi?
No. Your data stays in the EU and is never used to train anyone else's model. Lexi runs as a multi-tenant platform with each client's data kept isolated.
Can we edit what Supporter writes?
Yes. Every draft opens in a full editor, format it, rewrite parts, or adjust anything before you send it.
Who's behind Lexi?
A team of behavioral psychologists and engineers in Zagreb. Twelve years of writing psychology, now built into software.
With Supporter, every customer knows they matter.
