- Zeoob makes realistic social media mockups for teaching, training and design.
- Every generator free, in your browser, with no sign-up to make or download one.
- It is a simulator, not a social network: nothing made here is posted anywhere.
What Zeoob is
Zeoob is a set of social media simulators. You pick a platform, edit a post, a story or a chat directly on a live preview, and download the result as a PNG or a PDF. Nothing is published, nothing is sent to Instagram or X or WhatsApp, and no account on any of those platforms is involved at any point.
People use it to show how a post will look before it exists, to build examples for a lesson, and to make the point that a screenshot is one of the easiest things in the world to fake.
Why it exists
Zeoob is built as a media-literacy, online-safety and copywriting sandbox — made for classrooms and marketing training, to simulate the high-stakes, consumer-facing feeds where public blunders, scams and viral posts actually happen.
Teaching anything about social media used to mean one of two things: describing a post in words, or using a real account in front of a class. The first is abstract and the second is a risk. A simulator removes both problems — a realistic example, made in a minute, that belongs to nobody and reaches nobody.
The same is true in training. A marketing team can draft a launch thread, see it at the size it will really appear, and change it, without anything touching a live account.
How it is built
Every mockup is assembled in your browser while you work on it. The preview you edit is the same thing that gets rendered into the file you download, so there is nothing to be surprised by after you click Generate — at which point the image is sent to us once, to be watermarked and signed. Pages are kept deliberately light: a tool page is under 100 KB of our own code, fonts included, and loads no framework.
The tools work on a phone as a split studio rather than a desktop form squeezed onto a small screen — preview above, controls below, and you edit by tapping the preview.
What we ask
Label a mockup as a mockup. Every chat download carries a faint “Not an original screenshot” watermark for that reason, every download asks you to confirm responsible use, and the verification tool will read that mark back from an original file, though resizing or re-encoding an image destroys it.
What we ask beyond that is in Responsible use, and it is short.
How the watermark works
On the chat tools, that “Not an original screenshot” line is built to survive a crop. It is not stamped once at the bottom — it runs as three faint diagonal passes across the top, the middle and the bottom of the image, so cropping out a single message still leaves at least one mark in frame. It sits at a very low opacity: visible if you look for it, never defacing the mockup.
And it is there, on purpose, only for the chat tools — WhatsApp, iMessage, Messenger, Instagram, X, Snapchat and Discord conversations. A faked private dialogue is the format most often passed off as “evidence” — to mislead, to blackmail, or to put words in someone’s mouth — so that is where the mark belongs. Public posts, stories and memes do not carry it: they are rarely used as proof, and forcing a warning across every mockup would only push people toward a tool that adds nothing. The watermark is a safety badge for the place harm actually happens — which is also why a classroom can hand these tools to students and teach, in the same breath, that a screenshot is never proof on its own.
