Spling works with your existing website stack:

Most spell-checking tools rely on simple dictionaries. They check whether individual words exist, but they do not understand how language is used within a website context.
As a result, the most common issues are missed: 

  • localization mistakes
  • incorrect proper nouns
  • context-dependent grammar issues
  • UI copy
  • micro copy
  • dynamic or animated content

Spling delivers a higher standard of content QA. Instead of checking isolated words, it analyzes language in context. By considering page and site context, Spling can detect issues that traditional spell checkers often overlook.

This approach is especially important for marketing websites, where mistakes frequently involve more than spelling. Many errors involve mixing en-US and en-GB localization, inconsistent terminology, or incorrect brand and product names.

How does it work?

Using Spling is easy.

  1. Sign up
  2. Enter the website you want to check
  3. Select the pages you want to check, or check the full site
  4. Spling creates a report card with your results

Behind the scenes, Spling uses a proprietary content processing system that combines programmatic logic with guided AI to deliver high-quality results at scale. Pure AI approaches are expensive and inefficient, while simple rule-based or dictionary tools miss real issues while falsely reporting many others. Spling balances both to deliver thorough, context-aware checks without the cost of brute-force AI.
