What is WebSpellChecker?
WebSpellChecker is a content writing tool. Embeddable multilingual spelling, grammar and AI paraphrasing suite. Ships as SDK plugins for rich text editors, a web API, a browser extension, and WordPress or Drupal integrations, with cloud hosting on AWS or on-premise deployment for security-conscious teams.
WebSpellChecker is an engine first and a product family second. The company builds WProofreader, a proofreading and paraphrasing suite that development teams embed inside their own software rather than use as a standalone editor. The core covers spelling and grammar correction in more than 20 languages, with autocorrect and autocomplete suggestions, plus an AI writing assistant that can rewrite text, adjust length and style, and summarize key ideas. The same engine is exposed through a grammar check API, so custom systems can call it directly. The delivery options split into three tracks. Teams building web applications and rich text editors drop in pre-built components or plugins for CKEditor, TinyMCE, Froala, Quill, Kendo UI, ProseMirror, Trix and plain HTML controls such as textarea and iframe. Individuals install a browser extension for Chrome, Firefox and Microsoft Edge to check emails, documents and messages as they type online. Site owners can also run it inside WordPress and Drupal, and a SCAYT plugin handles CKEditor 4 with as-you-type underlining. Infrastructure matters here more than in a typical writing tool. Cloud hosting runs on AWS in the US East region, with automatic upgrades and backward compatibility built into the engine. On-premise deployment keeps all text on company servers, and licensing and pricing are shaped around the custom infrastructure the buyer runs. Data in transit is encrypted with TLS and the service is described as GDPR-compliant, which positions it for regulated and security-conscious organizations. That orientation makes WebSpellChecker a different purchase from consumer grammar assistants. It competes with embedded checking services on integration breadth, language count and deployment control. The training and documentation live partly on the separate wproofreader.com site, and licensing is quoted rather than listed, so evaluation usually starts with the free trial and the API documentation.
How do you use WebSpellChecker?
1Start with the free trial
Open the trial page and register to get access to the proofreading engine. The trial is the main self-serve path since licensing is quoted rather than published.2Decide between cloud and on-premise

Choose the product that matches the workflow: SDK components for web apps, a SCAYT plugin for CKEditor 4, WordPress for site content, or the browser extension for personal writing.4Wire up the grammar check API
For custom systems, use the web API to send text and receive correction and paraphrasing results. The API page documents the endpoints the engine exposes.5Test inside your own editor
Drop the component into your HTML controls or rich text editor and check spelling, grammar and style suggestions in as-you-type mode before wider rollout.6Ask about licensing and support
Once the pilot is validated, contact the team to agree terms for cloud or on-premise use. Sales and technical requests are answered within a business day.
