How it works

Three steps from “where do I start?” to a plan of action

01

Discover your strengths

Interactive tests for five paths: entrepreneur, specialist, freelancer, creator — or someone still searching.

02

Get a step-by-step plan

A personal strategy for growth and income: matching professions, priority skills and the first concrete steps.

03

AI consultant 24/7

Chat with AI about business and freelance — it answers with your test results in mind.

Who it is for

For anyone stuck on “what next?”

🧭
People who do not know where to start

You want change but every direction looks equally plausible. The test narrows an overwhelming field down to two or three real options.

🔄
People changing profession

You are moving into a new field and afraid of starting from zero. Get a plan that uses the experience you already have instead of discarding it.

💻
Freelancers and remote specialists

Designers, developers, marketers, copywriters deciding what to specialise in, what to charge, and which skills raise income fastest.

🚀
Beginner entrepreneurs

You have an idea or a small project and need a structure: what to do first, what can wait, and how to test demand before investing.

Worth knowing: AI answers are recommendations, not professional advice. Verify financial, legal and career decisions with qualified professionals.

Teleprompter app · Coming soon on iOS

Slay:
teleprompter for girls

The teleprompter app for filming Reels, TikTok and YouTube Shorts on your phone. Write the script with AI, read it while the text follows your voice, and speak to camera without memorising a word.

Voice-follow scrolling AI scripts 5 languages

Hey girl! 💕 Today I want to remind you: you're capable of more than you think.

Believe in yourself, don't be afraid…

0.5×1.5×

Why Slay

Not a grey broadcast tool. A phone-in-hand tool.

01

AI script writer

Type a topic and get a 30-second script ready to read. Ideas by category, your own idea box, and a library of hooks for Reels and TikTok.

02

Voice-follow scrolling

The text advances at the pace you actually speak — no chasing a fixed speed, no awkward pauses. Speed, size, line height and reading line are all yours to tune.

03

Two-window mode

Script and camera side by side with a draggable divider, plus mirror, loop and countdown. Presets for YouTube, TikTok, Reels and Podcast.

Everything in one place

From the idea to the finished take

Ideas & notes

Save an idea, turn it into a note, send the note to the prompter. Swipe an idea to move it, script it or delete it.

Shoot calendar

Plan filming days, keep tasks in one place and get reminders before a shoot, so content stops being a last-minute panic.

Made to look like you

Nine fonts, your own text and background colours saved as swatches, highlight colours and pause markers in the editor, and a dark theme.

Who it is for

Made for people who film themselves

🎬
Reels, TikTok and Shorts creators

You post regularly and film alone, holding the phone. You know your subject but lose the thread the moment recording starts.

🤝
UGC creators working with brands

The brief has required phrases and a strict timing. You need the script exactly as approved, take after take, without twenty retakes.

💼
Experts, coaches and small business owners

You sell through video but you are not a presenter. The prompter removes the memorising so you can concentrate on speaking clearly.

😮‍💨
Anyone who freezes on camera

The red dot appears and the words go. You are not bad on camera — you are spending all your attention on remembering.

Probably not for you if: you film scripted content with a full crew and a hardware teleprompter rig, or you only ever post spontaneous unscripted stories.

Launching soon on the App Store

Leave your email — I'll write to you the day it goes live. No spam, promise.

Grocery list app · One-time purchase · Coming soon

Fridge Stickers:
the grocery list that remembers

The best shopping list app for stocking up your fridge. Other grocery apps remember what you wrote — this one remembers how often you buy it. Set milk to repeat every 7 days and it comes back to your list on its own.

How it works

A shopping list with reminders that fit real life

01

Repeat reminders

Every 3 days, weekly, monthly or any interval you type in — or a single date for a one-off errand. Snooze anything without breaking the cycle.

02

Buy soon card

Everything due in the next couple of days, gathered from all your lists into one card. A glance before you leave the house tells you what the trip is for.

03

Your data stays on your phone

Nothing is uploaded: no analytics, no advertising identifiers, no location. You buy the app once — there is no subscription and no ads, so nothing needs funding by your data. Six languages, sticky notes in your own colours.

Who it is for

For the people who actually do the shopping

🛒
Whoever does the weekly shop

You plan a big trip and still come home without the one thing you needed. Repeat reminders put staples back on the list before they run out.

👨‍👩‍👧
Families running a household

Separate lists by destination — groceries, pharmacy, household chemicals — so a trip has one clear purpose. Send any list as text to whoever is going.

🔁
People who keep running out of the same things

Coffee, washing powder, vitamins, bin bags. Long buying cycles are impossible to hold in your head — set the interval once and stop tracking it.

🔒
Anyone who does not want another account

A grocery list reveals your diet, medication and budget. Everything stays on the device: no sign-up, no analytics, no ads. You pay once for the app instead of paying with your data or a monthly fee.

Probably not for you if: you need two people editing one list live at the same time — shared real-time editing is not supported yet, though you can send a list as text.

Stop forgetting the coffee

Make your grocery list, tick it off, and let the reminders do the remembering.

From the book

Prompts you'll copy on day one

Chapter 10 · Claude + Cursor “You are my senior mobile developer. We're building [app] screen by screen. Before writing code, list the files you'll create and wait for my OK.”
Chapter 15 · The paywall “Write 3 paywall headlines for [app]: one about the outcome, one about time saved, one about FOMO. 6 words max each.”

Who this book is for

For solo makers shipping their first app

🎨
Designers who want to ship, not hand off

You can design the screens but stop at the code. This is the exact route from a Figma-style idea to a build in the store, using AI as the developer.

🌱
Complete beginners with no CS degree

No computer science background required. The book assumes you are starting from zero and explains the vocabulary as it goes.

📱
Indie makers stuck before launch

You have a half-built project and no idea how store review, subscriptions or paywalls work. Parts 5 and 6 are entirely about that.

People who want the prompts, not theory

Every chapter ends with the actual prompts used, so you can copy them into Claude or Cursor and keep moving the same day.

Probably not for you if: you are an experienced mobile engineer looking for advanced architecture patterns — this is a start-to-launch guide, not a deep technical reference.
