The moment right after you hit send

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: too long, off-brand, or written like a machine, and tells you exactly what to fix.

How Analyzer scores your texts

Four dimensions.
One score.

Grammar and style aren't what it checks. Analyzer looks at the behavioral response a text is likely to produce in the reader, and gives that a score from 0 to 100. We call that the BE score (behavioral economics score).

Conversational clarity

Does the text speak like a person, or a policy document?

Persuasion architecture

Is the message structured to motivate action, or just inform?

Emotional resonance

Does it connect to something the reader actually cares about?

Action & Urgency (CTA)

Is there a compelling reason to act now?

Together, the four scores produce one BE Score. Below 50 signals a rewrite. Above 80 means the text is working with the reader's psychology, not against it.

Under the hood

Built on four
proprietary layers.

01

BE Theory

Academic behavioral science: cognitive biases, psychological triggers, and how the brain processes persuasion.

02

BE Tactical

Channel-specific rules. What works in email is different from SMS or a push notification.

03

Context Layer

Industry-specific calibration, trained on your sector's communication patterns and customer expectations.

04

Analysis Engine

The proprietary system that generates the score, flags specific issues, and produces actionable feedback.

Questions people ask

Before you
request a demo.

Do we need to write a prompt to use it?

No. Paste in the text, select the channel, and Analyzer scores it automatically across four behavioral dimensions. No prompt engineering involved.

Is this just a grammar checker?

No. Analyzer doesn't check grammar or style. It scores the behavioral response a text is likely to produce in the reader, whether it's likely to be read, trusted, and acted on.

What's a BE Score?

A 0–100 score built from four dimensions: conversational clarity, persuasion architecture, emotional resonance, and action & urgency. Below 50 signals a rewrite. Above 80 means the text is working with the reader's psychology, not against it.

Which channels does it work with?

Email, push notifications, SMS, and banners today.

Does it rewrite the text for us, or just flag problems?

Both. Every analysis comes with specific notes on what to fix, plus a rewritten version you can use directly or edit further.

What languages does it work in?

Any language you need. The psychology behind persuasive writing 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.

Who's behind Lexi?

A team of behavioral psychologists and engineers in Zagreb. Twelve years of writing psychology, now built into software.
