byhand

Everything online today reads like AI slop. So the simplest way to be believed is to prove a human actually wrote the words. That's all this is. A verification link that says these letters came from fingers, not a model.

When you sign, we quietly run 18 checks on how the text was typed. We don't care who you are, only how the words arrived. If it reads as a real human at a keyboard, you pass.

Anywhere written text travels. Social posts, emails, blog posts, essays, student work, comments, captions. byhand doesn't care where the verified text ends up. It just gives you a link that proves you wrote it.

Typing on your keyboard. Editing, deleting, rewriting. Copying and pasting parts of your own message inside this field if you want to repeat something. Mobile autocomplete and IME are fine too.

Pasting in text from somewhere else (ChatGPT, your notes, anywhere outside this field). Drag-and-drop into the box. Bots, automation scripts, dictation, browser extensions that type for you. The signature only stands if you wrote it, character by character.

For now byhand only handles plain text. The workflow: type everything here, sign it, then copy the text along with your verification link and paste both wherever you actually publish (blog, email, social, doc). Add images, formatting, attachments on that final destination. Anyone who reads it can click the link and compare what you wrote with what got signed.

It technically works. But it goes against the spirit of byhand, and the risk lands on whoever does it. Writing with AI is one thing; signing it as if it were personally written is another, and the author's credibility is theirs to lose.
