Ways to show your writing is human, compared
Last updated 24 October 2026
A line saying you wrote it is free and proves nothing; a detector score is a guess about the finished text; a record of how the text was written is evidence a reader can weigh. Which one is worth using depends on what your readers need to be able to check.
| Method | What it shows | Can a reader check it? |
|---|---|---|
| A statement or “How I make this” | What the writer says | No |
| A badge such as Not By AI | That the writer chose to display it | No |
| An AI detector score | An estimate from the finished text | Can run it again, and it can be wrong |
| Google Docs version history | Dated versions of the document | Only with edit access, or screenshots |
| Grammarly Authorship | Typed, pasted and AI-assisted text, sentence by sentence | From the report the writer shares |
| Certified Human | A typed, paste-free session, with keystroke timing | From the link the writer shares |
| iwrote | How the text arrived: typed, pasted, deleted, and the pauses | Yes, in their own browser |
A statement, or Substack’s “How I make this”
A line at the end of a piece, an about page, or the statement Substack lets writers add to explain their process (Substack). It costs nothing and tells readers where you stand. It is also a claim anybody can make, including somebody who did not write their piece, so it reassures the readers who already trust you and does little for the ones who do not.
A badge such as Not By AI
Not By AI offers badges for work its maker estimates is at least 90% human, free for non-commercial use and with a subscription for commercial use. It says plainly what it is not: “Not By AI is not an AI detection tool,” and it is for people who want to advocate for human work “rather than for those seeking evidence of human-produced content” (notbyai.fyi). A badge is a statement with a design.
An AI detector score
Pangram, GPTZero, Turnitin and others estimate how much a finished text resembles a model’s. Anybody can run one, which makes it feel like evidence, but it is a guess about the words, and it flags human writing, especially clear, edited prose and writing in a second language. Using one on your own drafts invites you to change your style until it stops objecting. Why detectors flag human writing.
Google Docs version history
Free, already there if you write in Google Docs, and good evidence: a dated trail of a document growing over days. But only somebody with edit access can see it, so showing it means sharing the document or taking screenshots; unnamed versions merge over time; and its owner can delete it. Using version history as evidence.
Grammarly Authorship
Works inside Google Docs, Microsoft Word and Grammarly’s own editor, and records whether text was typed, pasted or AI-assisted. It produces a report, colour-coded sentence by sentence, which you decide when to share. It needs a Grammarly account and the extension or app, and its page speaks mostly to students handing work to a teacher (Grammarly).
Certified Human
A web editor built by the journalist Harry Cheadle (his post). You type a calibration passage, then write with pasting blocked while every keystroke is recorded, and it gives you a signed attestation and a link to put on your post (certifiedhuman.tech). Blocking paste is strict: a quotation has to be typed out, and a draft written elsewhere cannot be brought in.
iwrote
A place to write in the browser that records how the words arrive: what was typed, pasted in, deleted and rewritten, and where the pauses fell. Pasting is allowed and recorded as pasting, so a quotation is fine. When the piece is done you certify it and put a short link under it. Whoever opens the link sees how the piece was written, and can check the record without taking iwrote’s word: it is signed with a published key, dated by a timestamping service iwrote does not run, and, if the writer shares the log, recomputed in the reader’s own browser.
- The cost: you write in iwrote, not in the Substack editor, Google Docs or wherever you write now.
- It covers writing done on iwrote, from the first word. It cannot vouch for a piece already published.
- It is evidence about a writing session, not proof of authorship, and what it cannot establish is written down.

Which should I use?
- If your readers already trust you, a statement may be all you need.
- If you write essays in Google Docs for a teacher, keep the version history, or use Grammarly Authorship where your school accepts it.
- If readers you have never met need to be able to check, you need a record they can open from the piece itself, like Certified Human’s or iwrote’s. Choose between those on whether you can give up pasting, and on whether a reader can check the record without trusting whoever issued it.
