Proof that a human typed it - not AI

The concept, and why it matters.

The problem

Since the moment we first played with generative AI, it was clear the internet would be flooded with machine-written text. A large and growing share of what you read online was never typed by a person - and, with visuals aside, you usually can’t tell the difference.

The idea

A Proof of Type is a verifiable link that shows a post was typed, in real time, by a human - not pasted from an LLM and not pushed by a bot. It doesn’t judge what you write; it attests how it was written: by human hands, key by key.

How it works

You type your post on proofoftype.com - a place where only humans can type: no pasting, no AI, no bots. Posting requires a hardware-level human check on your own device. When you’re done, you get a Proof of Type link to share alongside your words, wherever you post them.

The promise

If you see a Proof of Type link, you know you can relax and enjoy reading genuine human thoughts.

Where it matters

The same promise, wherever words carry weight.

Thought leadership

When you share what you actually believe, your voice is your credibility. A Proof of Type says these ideas came from a mind that has skin in the game - so people follow you, not your autocomplete.

School work

A student’s own words are how they learn to think. Proof of Type lets honest effort stand tall in a world where a quiet suspicion - “did a machine write this?” - now shadows every assignment.

News

In a flood of synthetic articles, trust is the whole product. A reporter’s Proof of Type is a small, human promise: a person went, saw, weighed it, and wrote it - and stands behind every line.

Speeches

The words meant to move a room should come from a beating heart, not a prompt box. Proof of Type keeps the human in the room, so when you’re stirred, you know someone truly meant it.

Essays

An essay is a person wrestling an idea to the ground in real time. That struggle is the entire point - and it deserves to be provably, unmistakably theirs.

Literature

Stories carry a soul because a human lived long enough and felt deeply enough to write them. Proof of Type protects that lineage, so the ache in a sentence is one that was really felt.

Scripts & plays

Great dialogue is overheard humanity. When a writer proves they typed it, the characters stay ours - flawed, funny, alive - instead of generated.

Songs

A lyric is a confession set to rhythm. Proof of Type keeps songwriting an act of the heart, so the line that makes you cry was written by someone who could.

Proof of Type

It was clear from the moment we first played with GPT, that we're going to be flooded with AI written posts. Already—content online is 50—50. (em—dash—are—safe—again)

How important is to you—to know if what you're reading is typed by a human? putting visuals aside for now.

To be sure it was typed by a human, we need a Proof of Type, to know it wasn't pasted from an LLM or pushed by a bot.

You can get that Proof of Type as a link when you type first on ProofOfType.com, where only humans type and paste your post with the link.

P.O.T is built to prevent bots or AI to post and requires human hardware level ID.

TL;DR

If you see a post with a ProofOfType link, you'll know you can enjoy reading human thoughts.
