#2Cool idea. Needs a demo to show how it actually works and not just for decoding messages. Like what's the use case.
Also, all those trademark symbols makes this look comically unprofessional.

Hey thanks for the feedback! Definitely will add a video shortly just putting it out there to get great feedback like yours.

#4Hi there, great idea. Sort of like text stenography.
Is the message really hidden in this message? Or are you just doing the lookup your database of hidden messages based on the hash of the public message?
Regarding the website UX - after I pasted the message to your text field I thought the hidden message is the youtube video. But that didn't make sense to me and only later I understood the message is above the video.
If you are interested in more UX feedback, feel free to visit https://usability.testing.exchange which is a free community platform built exactly for this purpose.
Also, looking at the payment options - I'm missing a pay-per-message approach. For your consideration.

#6I only changed a word from it and it wouldn't find the trademark anymore. Not that useful IMHO.

#7Interesting. Did some quick poking around.
Looks like the system adds a number of non-printing unicode characters into the string. In this thread title, for example, the textmark is stored in the phrase "message has a hidden message inside." (Thanks, textdiff!)
Specifically, it adds non-printing unicode characters repeatedly. I'd guess these form a unique series, which is mapped to a record in the textmark database.
If I wanted to automatically remove the textmark from a text, in order to steal your content, I would write a script to automatically remove any non-printing unicode characters that appear in it. This StackOverflow answer includes a script achieving precisely that task: https://stackoverflow.com/a/11598864/6226586

Also, this reminds me of a Clara Labs (YC S14) project to hide unique IDs in unicode text: https://blog.claralabs.com/invisible-ink-a-simple-but-faulty...

#9Hey textmark.io! Steganography is so cool, but ensure ownership without a robust crypto system is a little bit pretentious ... And in some cases, dangerous!

I was thinking the same things like you. Looks like they don't event hide the actual message. They basically hide some sort of ID that points a row in the database. After some research I've made a web-app which can hide any message into any text.
If you wanna look it's on GitHub. Here are the links.
