Web Tech Survey reports that the total number of live sites using rich text editors is approaching 320K as of March 2022. It’s about 0,30% of all websites existing today.
Rich text editors (RTEs) or WYSIWYG editors are interfaces for managing and formatting written content in web apps and platforms within web browsers. Unlike standard HTML text areas, these UI controls offer tons of features.
RTEs deployment isn’t limited by web only, many companies use RTEs within custom infrastructures and intranet systems.
With the global mainstream to digitalization, online editors have gained even more popularity. By extending the list of native features, these tools cover almost all functionality required for editing texts online. Spell and grammar check is one of the top features highly demanded now.
And it’s obvious given the impact poor content proofreading may have on the brand image.
Spell check solutions for editors vary. Meanwhile some provide basic functionality, others go far beyond.
We’ve done research and analyzed the market of spell check plugins for RTEs.
TL;DR: commercial third-party spell check solutions seem to be more beneficial for complex projects than native tools as they bring more dev opportunities. Keep reading to learn more.
Spell check plugins for WYSIWYG editors: market overview
According to statistics, the top four RTEs are: CKEditor, Froala, TinyMCE, and Quill. CKEditor is leading the squad with 42,35% market share. Quill editor is considered to be the fastest-growing technology.
CKSource, the company behind CKEditor, describes some of the editor deployment use cases:
- content creation and communication platforms and tools;
- collaborative mediums;
- project management platforms;
- content creation platforms and CMS;
- note taking tools.
Froala editor is actively deployed for sales CRM, showcase platforms.
TinyMCE works with project management software vendors, mass media and information platforms.
Advanced automated proofreading is a must-have feature for any platform or application where users process, manage or interchange textual information.
Speaking about web-based projects, native browser spell checkers may be a go-to.
Basically, they offer free multilingual spell check with some bells and whistles like autocomplete and autocorrect (Google Chrome), dictionaries (Firefox spell checker), and writing refinements (Microsoft Editor browser extension). But when it comes to custom infrastructure and consistent behavior for all platforms regardless of browser or device, a built-in or third-party proofreading solution is much required.
CKEditor (formerly known as FCKeditor) is a WYSIWYG rich text editor which enables writing content directly inside of web pages or online applications.
CKEditor has two solutions – CKEditor 4 and CKEditor 5. The latter one is equipped with a more modern toolkit and actively promoted by CKSource as a more innovative solution. CKEditor probably has the largest number of third-party proofreading tools – WebSpellChecker, Sapling AI, and ProWritingAid.
WebSpellChecker has been a partner with CKSource for many years. In the scope of this partnership, our team developed the SCAYT plugin and WProofreader for CKEditor 5 and an integration for CKEditor 4. The SCAYT plugin comes in free and commercial versions. WProofreader is a commercial product with a free trial.
BeyondGrammar by ProWritingAid allows you to quickly integrate grammar checking, spellchecking and style improvements into CKEditor.
Froala has a native spell check plugin for users to see and correct misspellings while typing. Besides, Froala is compatible with proofreading tools by WebSpellChecker and ProWritingAid. Both offer capabilities similar to their integrations with CKEditor.
WProofreader component for Froala: spell and grammar check, autocorrect and autocomplete suggestions, language autodetect, user dictionaries. Plus, clients can customize the behavior and UI of WProofreader components for RTEs via API options.
ProWritingAid app for Froala enables grammar, spell, and terminology checking, style improvements inside the editor.
TinyMCE is an online rich-text editor released as open-source software under the LGPL.
The editor actively promotes its native solution – Spell Check Pro Plugin. The tool offers consistent spelling check as-you-type with custom dictionary support in multiple languages. Spelling suggestions are available in an in-dialog mode. The plugin doesn’t support grammar – an important limitation to take into account.
The core feature of the plugin is the multi-language environment: the user selects the part of the text and defines the language for checking from the UI.
WProofreader integration for TinyMCE is highly secure, customizable and accessible. The toolkit is the same as for the rest of integrations with other RTEs.
Quill is a free, open source customizable WYSIWYG editor with modular architecture and expressive API.
There’s no native proofreading solution for Quill, developers use a third-party SDK/API or may build a custom module. Both WebSpellChecker and ProWritingAid offer feature-rich components/applications for Quill deployed on cloud or on-premise. The toolkit is the same as for integration modules for other editors.
ProWritingAid app for Quill is an open-source project on Github, free for individuals. For multi-user instances, you will need a commercial license.
So, here’s a brief overview or introduction, if you’d like, into the market of spell check solutions for rich text editors.
To get deeper and choose the right option, you should carefully compare all the prerequisites (deployment type, customization options, limitations, pricing, and documentation). We’ve done some tough job to save your time on the comparison.

No matter what solution for people communication or interaction you build, you will probably need an RTE. And CKEditor, TinyMCE, Froala or Quill will get you covered. The point is that not all RTEs have built-in proofreading modules.
Certainly, you may use a native browser solution, but it won’t work for intranet projects or you may try to build a custom tool. But there’s no good reason: it’s expensive, time consuming and just irrational.
WProofreader SDK for developers

There are many off-the-shelf solutions like WProofreader SDK, Spell Check Pro Plugin by TinyMCE, ProWritingAid apps for RTEs or Sapling AI integrations with CKEditor.
By a rule of thumb, native spell checkers like Spell Check Pro Plugin by TinyMCE come with limited functionality, e.g. pure spell check. Commercial third-party tools are richer in terms of features, they offer more security options and API customization opportunities. And therefore, they’re pricier.
What to pay attention to when choosing a third-party proofreading solution for your editor?
- Technical capabilities and limitations: processing volumes, cloud usage quotes, the number of seats under a subscription available.
- Core and extra features like autocorrect, autocomplete and dictionaries.
- RTEs support. It’s better to opt for a universal solution like WProofreader SDK which covers the majority of editors – you may need to migrate once.
- SDK and API options. SDK comes with predefined UI and makes app development easier, APIs help build custom capabilities.
- Pricing model: monthly/annual fees, deployment (on-premise vs cloud), support and maintenance services.
- Public legal documentation. A vendor should provide you with license agreement or terms before making a deal – no alternative.
