## What is Subliminal?

Magicians already have a bunch of ways to peek or force a word:
From analogue methods like a Center Tear, to something more modern, such as WikiTest or DFB X.

But what magicians *don't* have are many interesting ways to reveal that word. 

This is why I created Subliminal:

Subliminal uses AI generated imagery to reveal a spectator's thought, hidden in a photo that they were looking at *the entire time*!

** Here's an example of one effect possible with Subliminal:
- To begin, you show your spectator a photo on your phone.
- You zoom in on the photo, before leaving your phone on the table and you never touch it again.
- The spectator is asked to name a word. 
- You then ask the spectator to zoom out of the image, where they now realise that the word they named has been seemingly hidden within the photo the entire time.

** Subliminal also works perfectly with your existing effects!
Let's say you've performed an effect (perhaps you’ve peeked a word) and have learned the spectator's thought-of word.
Rather than just telling your spectator their thought, Subliminal lets you reveal this thought creatively! It's perfect in conjunction with existing analogue and digital effects, from a Center Tear peek to DFB.

Features:
* Photo Grid
You show the spectator some photos in the Photos app on your phone. As you slowly zoom out, the photos turn into letters, which reveal the spectator's thought!

* Single Image Modes
Reveal the spectator's thought of word within a photo of dogs, windows on a street, the tops of mountains, and more!

* Stretched Images
Stretched image modes further disguise the reveal until the spectator looks at the screen at an angle, for a fun reveal.

* Upside down stretched images
Flip the phone upside down to see the hidden word.


** Multiple input methods are included, enabling multiple effects:
- Gyro input - for precision typing.
- Voice input - with voice peek.
- Earworm Notes - a realistic notes app input.
- Earworm Web Search - use covert web search input with Subliminal.
- WikiTest integration - have the spectator’s Wikipedia search automatically update the image.
- Bridge integration - for use with many other apps and AI text inputs.
- Open API - for third party integrations.
- URL triggers - use Shortcuts to change your iPhone's wallpaper, and more!

As well as native WikiTest, Earworm and Bridge integration, Subliminal also supports your favourite magic app’s API.
Plus, Subliminal can even be triggered via a URL, meaning Shortcuts can tie in with the app to change your iPhone’s wallpaper, and more!

Subliminal currently supports any words or phrases that use the characters A-Z, spaces, and numbers 0-9.

At the conclusion of the effect performed with Subliminal, you can even share the photo with the word to your spectator, leaving them with the memory of the effect on their phone!

No extra hidden costs, purchases or subscriptions - Subliminal is all you need to generate your own hidden text AI images!

I highly recommend this to any magician who is serious about impressing friends.

### 5/5 — Subliminal is Sublime

*2024-05-18*

As always, Marc has created an intuitive interface for this app making it easy to navigate and utilize. This app can be used stand-alone or combined with other magical principles and/or integrated with other apps for increased versatility and expanded routining. I urge folks to think outside the box to realize the full potential this app has to offer. Highly recommended!

### 5/5 — impressive

*2023-10-11*

Visual revelations are very impressivePlease incluse mutal vowels for the german language, otherwise voice input dies not work with Löwe (lion) for example...

### 3/5 — Outstanding

*2023-10-09*

I got this at its most basic but every time I go to use it there are new features added and it is now a fantastic magic trick/utility well worth the money.  Yet again Mr Kerstein goes above and beyond expectations.

### 1/5 — Déçu

*2023-10-03*

Cette application ne sert pas à grand chose.
Mentaliste professionnel, je voyais dans l’utilisation de cette appli l’opportunité de faire des révélations de prédiction, de manière originale.
Mais l’application n’est juste qu’un album photo de quelques photos représentant une seule lettre.
Grosse déception!

### 5/5 — Amazing

*2023-09-25*

I love this app. It will only get better when Marc adds new features to it later on. Great buy
