How verification works
Most proofreading agents show you every suggestion and make you sort the good from the bad. Verant is precision-first — tuned to flag only indisputable errors and benchmarked against a labeled evaluation corpus. What's worth fixing is what we show you. Verbatim is sacred: every flag quotes your exact text; we never auto-apply fixes.

When to choose Spling
Choose Spling if you want metered, pay-per-page checks or an API to drop into your own pipeline — its credit model, 50+ language support, and programmatic access are real strengths, and for occasional one-off checks or for proofreading emails and PDFs, it's the better fit. Choose Verant when you want a verified proofread of the whole live site on a predictable flat plan: only indisputable errors flagged, clarity and style and leftover placeholder text caught alongside spelling, a corrected-copy export, and weekly monitoring that re-scans only the pages that changed.
When Spling is the better choice
- You want pure pay-as-you-go — buy a handful of page credits, spend nothing more — instead of a monthly subscription.
- You're API-first and want to wire programmatic checks into your own build or CMS pipeline.
- You need to check beyond websites — emails and PDFs, or in a non-English language — which Verant does not cover.
Frequently asked questions
How does Verant's pricing differ from Spling's?
Spling is metered — you buy page credits at a few cents each, or an unlimited plan for one site. Verant is a flat self-serve subscription from $19/mo with a fixed page ceiling per tier (up to 500 pages on the top plan), so a full-site scan plus weekly monitoring is one predictable price rather than a per-page meter.
Does Verant have an API like Spling?
Not a public proofreading API. Spling offers a programmatic checking API on its business plans. Verant exposes MCP tools (proofread a URL or a site, fetch a scan) to signed-in Pro and Ultra users, but its core surface is paste-a-URL with a verified report, corrected-copy export, and watch-my-site monitoring.
What does Verant catch that a spelling-and-grammar pass misses?
Beyond spelling and grammar, Verant flags style, clarity, and leftover placeholder or merge-field text like `{{first_name}}` or stray lorem-ipsum — and holds each suggestion to an indisputable-error bar, so the site-wide result is a short list of real errors rather than raw, unfiltered hits.
