# Every reply written the way you write, not a script.

Paste a few replies you have written so SetLuca can learn your phrasing, openers, and emoji. New drafts use that editable profile.

## From your replies to your next reply.

There's no training step you have to sit through. The setup is connecting a channel; everything after that happens while you get on with your day.

1. **Connect a channel** (you). On Instagram and Messenger, SetLuca reads your recent replies once to learn your writing style. On Telegram, paste a few replies. No questionnaire to fill in.
2. **It builds your profile** (SetLuca). Openers, sentence length, emoji, how you handle price, how formal you get per language. All of it visible in your settings.
3. **Every reply goes out the way you write** (SetLuca). Written as you, checked against your real offers and prices. It sends the moment it's drafted, or waits in your queue if that channel is set to review.
4. **Your edits sharpen it** (you). Change a word, before it sends on a review channel or after on an auto-send one, and SetLuca notices the difference. The same correction seldom comes back twice.

## How SetLuca learns the way you write.

Leads followed you for the way you talk. A reply that books the call but reads like a template spends that down, one message at a time. They feel the difference in a single line, which is why the way you write carries the rest of what SetLuca does.

### Learned from your own replies

On Instagram and Messenger, SetLuca reads your recent replies once, at connection, to learn your writing style. Only your replies are kept; leads' messages are discarded and old conversations are not brought in. On Telegram, paste a few replies you have written. The writing-style profile is editable.

- Learns your openers, phrasing, and emoji habits
- Keeps your prices, offers, and program names straight
- No writing prompts, no setup questionnaires

### Every edit you make retrains it

Each time you tweak a draft, SetLuca notices what you changed. The gap between what it writes and what you'd write shrinks week after week, until most drafts go out untouched.

- Every edit teaches it something specific
- Weekly refresh from your newest DMs on Pro and Scale
- The way you write today, not last year

### Read your writing-style profile, and correct it

Your writing-style profile is a page in your settings, open for you to read. See what SetLuca learned about how you write and correct anything that feels off. Nudge the tone warmer or more direct when the situation calls for it. The change applies to the next draft. You can also

- Open your writing-style profile any time
- Fix a phrase once and it sticks
- Tone controls for when you want them

### Full register in three languages, mirrored in the rest

SetLuca answers in the language the lead used. English, Spanish, and Brazilian Portuguese get full register rules learned from your replies in each one. For any of the other 13 languages it detects, it mirrors the lead's language on a best-effort basis and never mislabels it as English.

- Full register in English, Spanish, and Brazilian Portuguese
- Best-effort mirroring across 13 more detected languages
- Never mislabels a message as English

## Three replies where the way you write decides the outcome.

In each one, a generic reply and a SetLuca reply part ways. The gap is wide enough to decide whether the thread keeps going.

### The price question

"how much is your program?" The message every seller answers ten times a week.

SetLuca gives your real number the way you give it, then asks the question you always ask next instead of leaving the price sitting there alone.

### The 2am lead

Someone messages at 2am, mid-scroll, half-committed, three words long.

The reply is three words long too. Matching the energy of the message is most of reading as human.

### The second language

A lead opens in Spanish and you sell in Spanish, but not the way you write English.

SetLuca answers in Spanish using your Spanish register, learned from your own Spanish replies rather than translated across from your English ones.

## Why most AI replies read as AI, and SetLuca's don't.

You've seen the tell. Perfect grammar, no pulse, and not a line any real person would type between sets.

### A generic assistant

- Opens with "Hello! Thank you for reaching out". A lead texts "yo how much" and gets back "Hello! Thank you for reaching out to us." The register mismatch is visible before the second sentence.
- Writes in full paragraphs nobody types on a phone. Four correctly punctuated sentences in one block, where a real reply would land as two short texts a beat apart.
- Hedges on price because it doesn't know yours. "Pricing varies depending on your goals, feel free to book a call to discuss!" No number, because nobody gave it one.
- One flat register for every lead and every language. The same polished tone for a one-word 2am message and for a lead who opened in Spanish, because it has no version of any one person to fall back on.
- Reads the same as everyone else using the same tool. Swap the business name in the template and the message reads the same, because none of it came from anyone's real DMs.

### SetLuca, writing as you

- Opens the way you open, lowercase and all. "hey!!" instead of "Hello!" because that's the greeting you use.
- Matches your length, your rhythm, your emoji. A three-word lead gets a three-word reply back, in your emoji, not a paragraph padded out to sound thorough.
- States your real price, checked against your own profile. "how much is your program?" gets your real number in the first line, then the question you always ask next, instead of a redirect to a call.
- Shifts register per channel and per language, like you do. SetLuca adapts each channel's tone to the way you write there, and mirrors the language the lead used.
- Learned from your replies, so it can't read like anyone else's. Two businesses using SetLuca get two different replies for the same lead message, because each profile came from a different set of replies.

## The details, for people who want them.

What goes in, what comes out, and what never leaves your account.

- **What it reads.** On Instagram and Messenger, your recent replies, read once at connection. On any channel, replies you paste in during setup.
- **What it never reads for your style.** It learns how you write, not what your clients told you. Leads' messages inform the reply, never the writing-style profile itself. Old conversations are not brought into your inbox.
- **How much it needs.** A few dozen real replies is enough to pick up your register. It sharpens from there with every edit you make.
- **Refresh.** Your edits teach it on every plan. The weekly refresh that keeps the profile current without you doing anything is included on pro and scale.
- **Visibility.** Your writing-style profile is a page in settings you can read and correct. Changes apply to the next draft.
- **Facts and prices.** Offers, prices, and program names come from your profile, and SetLuca checks every draft against them before it reaches your queue.
- **Languages.** SetLuca detects 16 languages and drafts and critiques with full register rules in English, Spanish, and Brazilian Portuguese. For any other detected language, it mirrors the lead's language on a best-effort basis and never mislabels it as English.
- **Sales framework.** You pick the framework SetLuca sells with: Sandler, SPIN, Challenger, NEPQ, GAP, Straight Line, or a custom one you describe in your own words. The drafter and critic both follow that framework's stages.
- **Multi-part drafts.** SetLuca can split a reply into up to 4 short messages, the way you'd text it yourself. Turn it on in your app settings.
- **Isolation.** Your writing-style profile is scoped to your account, never pooled with other customers, and never used to train a shared model.

## Questions

### Won't my leads notice it's AI?

They'd have to notice something that isn't there. SetLuca drafts from your own replies, not a generic model's idea of helpful, so a draft carries your sentence length, your emoji, and your real price. Switch a channel to review to read every draft before it sends, and judge it on your own queue, not this page.

### What if a draft doesn't read like me?

Switch that channel to review and edit it before it sends. On an auto-send channel, correct it in the thread after. Either way, SetLuca learns from every edit you make, so the same miss rarely repeats. You can also open your writing-style profile in settings and correct anything that feels off.

### What happens if a lead writes in a language you don't have full register for?

SetLuca still answers in that language rather than defaulting to English; it mirrors what the lead wrote on a best-effort basis. Full register, the kind that matches your actual tone, is there for English, Spanish, and Brazilian Portuguese. Every other detected language gets a solid best-effort reply instead of nothing.

### What happens if the way I write changes over time?

It follows you. Every edit you make teaches it, on every plan, and on Pro and Scale it also refreshes weekly from your newest DMs without you doing anything. Rebrand or change how you sell and it catches up within a couple of weeks, sooner if you edit a few drafts to show it.

### Is my message history used to train anyone else's SetLuca?

No. Your writing-style profile is yours: scoped to your account, never pooled with other customers, and never used to train a shared model. Delete your account and it goes with it. On Instagram and Messenger, SetLuca keeps only your own replies from the one-time read at connection; leads' messages are discarded.

### Does it copy my typos and bad habits too?

It keeps the habits that make you read as human: lowercase openers, the way you trail off, your particular emoji. It drops the ones that read as careless rather than casual. The goal is you on a good day, not a transcript.
