Java specifications
Dictionaries available for RapidSpell Web ASP.NET

Global reach

4 English language variations (US, UK, CA, AU) included free of charge with 17 extra dictionaries also available, including medical and legal. All of which are modifiable.

Online Demos

These demonstration pages are included in the download ZIP as a demo project.


With full API access, customizations can be made to behavior such as working with user dictionaries in a database format instead of the default text file format, altering the parser to check for offensive language or changing the way words are identified and their corresponding suggestions.

In addition, developers can use the core spell checker functionality through the RapidSpellChecker class, allowing usage without the GUI in console and server applications for example.

Customization feature

Minimal application footprint

By adding 2 <script src...> tags you automatically configure the spell checkers (as you type + dialog) to work with all text boxes in the form. Specific text boxes can also be ignored using nospell attributes or the Javascript API.

Html editor support

Custom dictionaries

The user interface can easily be restyled by extending its class and overriding the design method (an example of this is included). The spell checker engine can be completely separated from the GUI allowing you to customize behavior.


RapidSpell has built-in multi-lingual support, offering the GUI in several languages. Multiple non English language dictionaries are available including Medical and Legal dictionaries.

Easy Setup

RapidSpell Web Java can be used by either importing 2 Javascripts onto your page (it will automatically set itself up) or through JSP tags. RapidSpell Desktop Java can be used with 2 lines of code.

No post-back interface

All dictionaries (main and user's) are stored on the server, yet the user's spell checking experience is not hampered by any post-backs to the server, because there are none. User dictionaries can be stored on a database (examples provided).

Dictionary Manager

The Dict Manager tool (included free of charge) provides Java Swing & JavaFX and JEE developers with a user friendly method of maintaining the dictionaries. Add, lookup and remove words. Create new dictionaries or merge existing word-lists.

'Sounds-like' or hashing suggestions

As each user and each application is different, sometimes you need to offer spelling suggestions tailored to your target audience. RapidSpell offers two different suggestion mechanisms to find the best suggestions for words.

HTML text box support

RapidSpell Web Java can add spell checking to any HTML text box component as well as 3rd Party text components such as HtmlArea and FCKEditor.

Full browser coverage

RapidSpell Web Java supports all major browsers and requires only HTML and JS to enable spell checking for your J2EE applications.
