Pass Substack's AI scan and keep your reach

It works: EndSchool.today passes Pangram and Turnitin, and in our tests it also passes GPTZero, Originality.ai, Copyleaks and ZeroGPT. That matters now because Substack's "Scan for AI text" runs on Pangram, the strictest detector on the market, and LinkedIn cuts reach on AI-looking text. EndSchool.today checks every result with the same Pangram before you see it. If it passes here, it passes there.

Most newsletter writers use AI somewhere in the process now. A first draft, a tighter intro, a cleanup pass on a 2,000 word issue. Readers do not mind. Platforms do. Substack's scan flags it, LinkedIn's feed buries it, and Medium's curation skips it. One flagged post can cost you a week of growth.

EndSchool.today rewrites the text so it reads as human, keeps your voice and your points, and attaches a viewable Pangram proof to every run. Meaning notes show you every change against your draft, so your jokes, examples and calls to action land the way you wrote them.

How to humanize with EndSchool

  1. **Paste your post.** Drop in the issue before you schedule it. Keep the original tab open so you can compare.
  2. **Run it.** EndSchool.today rewrites the text and checks it with Pangram, the same detector behind Substack's scan. You only see results that pass.
  3. **Open the Pangram proof.** Every run attaches a viewable report. Keep it, or share it if anyone asks.
  4. **Read the meaning notes.** They list each change against your draft. Put back any line you want word for word, then publish.

FAQ

Does it pass Substack's AI scan?

Yes. Substack's scan is built on Pangram. EndSchool.today checks every result against Pangram before you see it, and only passing results come through. The proof is attached to each run.

Will it keep my voice?

Yes. The rewrite keeps your tone, structure and points. The meaning notes show every change so you can restore any line you want exactly as written.

Does it help on LinkedIn and Medium?

Yes. LinkedIn reduces reach on posts that read as AI, and Medium's curation does the same. EndSchool.today makes the text read as human on every platform, not just Substack.

My post is 2,000 words. How do I run it?

Split it by section. Paid runs are up to 1,200 words each. Most issues take two runs, and each one gets its own Pangram proof.

I write everything myself. Why would I need this?

Pangram flags human writing too, especially tight, well-edited prose. If your scan comes back red on a post you wrote, one run clears it and keeps your words.

Is my text stored?

Yes. We keep a research copy of what you submit and of our result, without your name or email, to improve the service and train our own models, with no set end date. Anyone with a result link can open that result until it's deleted. Don't submit anything you don't want kept. See the privacy policy.
