LanguageTool checks drafts. Verant checks every page you publish.
An open-source checker in your editor is a fine way to write. Verant picks up where it stops: crawling your live site, reading every page the way the CMS actually rendered it, and handing you every fix that survived its precision bar.
One page, yoursite.com, read two ways: LanguageTool sees the text box, as you type; Verant reads the published page as a visitor does and catches 3 issues in place, each quoted verbatim with its fix beside it.

When to choose which
Choose LanguageTool when
The right pick while the text is still yours to edit.
- You want checking inside the tools you draft in — or an API wired into your own writing flow.
- You work in languages beyond English.
- You want open source you can self-host, at zero cost, on your own terms.
Choose Verant when
The right pick once the text belongs to your readers.
- You need the whole live site read in one pass — including copy your CMS assembled that no draft ever contained.
- You want a short list you can act on, not a feed of suggestions to triage.
- You want weak suggestions dropped before you see the list, with your exact text quoted in every flag.
What ‘verified’ means
Weak suggestions are dropped before they reach you. What remains quotes the exact text on your page, with the fix beside it.

Frequently asked questions
Is Verant a replacement for LanguageTool?
They solve different problems. LanguageTool checks text as you write it — in your editor, browser, or via its API — and supports many languages. Verant proofreads your live published website, crawling every rendered page and flagging only errors it can defend. Many teams write with one and audit the shipped site with the other.
Can LanguageTool proofread my whole published website?
Not the way Verant does. LanguageTool runs where you type — an editor, a browser field, or an API call on text you send it. Verant crawls your published site page by page, reading each page the way a visitor sees it after the CMS renders it, in a single run.
Does Verant support other languages or self-hosting like LanguageTool?
No. LanguageTool is open-source, self-hostable, and checks dozens of languages — real strengths if you need those. Verant proofreads English copy on your published pages for grammar, spelling, punctuation, style, and clarity, plus leftover placeholder text, and runs as a hosted service.
How do I start using Verant if I already write with LanguageTool?
Keep LanguageTool where you write — the two do not overlap. To add Verant, paste your site’s URL and run the first scan: nothing installs, and the free trial needs no card. One checks your drafts; the other audits what actually shipped.
