AI writing platform for businesses, trained by psychologists

Be read. Be loved.

Control what your company says. And how your customers feel. With psychology.

Every message sends two things: words and a feeling. Lexi puts both under your control, before you hit send.

The problem

Your company is mostly text to your customers

Every brand is using AI to write now. Which is exactly why most of it sounds the same.

See what we do differently
/ 01

Same tools, same training data

Everyone prompts the same models on the same scraped internet, so every brand arrives at the same flattened, careful tone.

/ 02

Readers can feel it, and stop reading

The words are grammatically perfect and emotionally empty. Open rates hold, engagement quietly drops.

/ 03

Fifty people write in your name

Marketing, support, legal, sales — each with their own voice. Your customer reads one company.

Companies manage what they spend.
Lexi manages what they say.

Most AI tools learned to write from the whole internet. Lexi learned from twelve years of psychologists and writers deciding, sentence by sentence, what actually works.

That's true for all three tools. Each one is trained to ask the same question before it writes anything: what does this specific person need to feel right now to act, to calm down, or to trust you? 11,500+ hand-written texts and twelve years of research go into answering that, every single time.

Three tools.
One psychology platform.

Copywriter

Persuasion. Turns cold copy into text that gets read.

Your marketing team needs an email out in ten minutes, and the last three drafts all sound the same. Copywriter learned from real copywriters and psychologists, not from the internet.

  • Learned from real copywriter texts, not scraped pages
  • Sounds like a person wrote it
  • Says what makes people act

Supporter

Empathy. Calms an angry customer before you even reply.

Someone just sent you the same complaint for the third time, and you've got five minutes before it turns into a refund request. Supporter reads the anger and drafts a reply that actually calms things down.

  • Reads the anger before you do
  • Calms things down in one reply
  • Built on 10 years of positive psychology

Analyzer

Precision. Catches what's off-brand before 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, and tells you exactly what to fix.

  • Catches it before you hit send
  • Flags stiff, off-brand or robotic lines
  • Says exactly what to fix

See these three on your own brief.

Bring one email or reply you actually sent. We'll show you what Copywriter, Supporter and Analyzer do with it.

More than writing
a complete communication engine.

Image generation

One request produces the text and the visual together: royalty-free images generated to match your brand's tone, no design tool required. Social posts, email headers, ad creatives.

Lexi Inbox

Lexi doesn't ask you to check one more inbox. It plugs into the tools you already use — email, WhatsApp, Instagram, your CRM or ticketing system — and Supporter drafts the reply before you open the message.

A guided brief.
Not a blank page.
