Verant · Verified, not guessed

Proofread your whole Substack the way readers actually see it

Substack rewards velocity — you draft, hit publish, and the post is live in front of every subscriber, often with no editor in between. Verant reads your published Substack the way a reader does: every post and page across your publication, in one crawl. Turn on monitoring and each new post gets proofread on the next weekly sweep — no manual re-scan.

Why Substack teams use Verant

How it works

  1. 1

    Paste your publication URL — your custom domain or `yourname.substack.com`.

  2. 2

    Verant renders each published page and follows your archive so it reaches every public post plus your About and section pages, not just the latest issue.

  3. 3

    Two models proofread the rendered post copy and the second refutes weak suggestions — you review only verified fixes, post by post.

On Substack

On Substack, Verant reads the published web version of each post — headline, subhead, and body as a reader sees it — and follows your public archive to reach older posts and your About and section pages. It proofreads the rendered article text; it does not read paywalled members-only content it can't access from the public URL.

How verification works

Most proofreading agents show you every suggestion and make you sort the good from the bad. Verant runs an adversarial second pass — Claude Sonnet proofreads, then GPT-5 tries to break each correction. What survives is what we show you. Verbatim is sacred: every flag quotes your exact text; we never auto-apply fixes.

Frequently asked questions

Does Verant work with Substack?

Yes. Paste your publication URL — a custom domain or `yourname.substack.com` — and Verant crawls your public posts and pages and proofreads the published web version each reader sees. It reads only what's public; it can't open paywalled content from the URL.

How do I proofread my whole Substack at once?

Run a full-site scan on your publication URL. Verant follows your archive to reach every public post plus your About and section pages, then verifies each fix with a second AI so you get one clean list instead of re-reading post by post.

What errors does Verant find on a Substack?

Grammar, spelling, punctuation, style, and clarity issues across your published posts and pages — including fast-publish typos and leftover draft stubs like "TK" or "[link here]" that survived to the live post.
