TidlyLelWiki - bu shaxsiy ma'lumotni tashkil qilish va baham ko'rish va almashish uchun shaxsiy Wiki va chiziqli bo'lmagan daftar. Bu CSS, JavaScript va tarkibni o'z ichiga olgan yagona HTML fayli shaklida bitta sahifadagi bitta sahifadagi dasturiy dasturdir. Ilovaga qarab sozlash va qayta shakllantirish oson bo'lishi uchun mo'ljallangan. Bu tarkibni qayta ishlangan kichik qismlarga ajratish orqali qayta foydalanishni osonlashtiradi.

TiddlyWiki is designed for customization and to be shaped according to users’ specific needs, perhaps comparable to a high-end programming language. As such, it can be shaped into a wide and arbitrary range of special applications. Examples include niche note taking applications, to-do lists, presentations, collections, authoring tools, personal databases, recipe collections, etc.

Although there are many TiddlyWiki documents on the Web, the majority of TiddlyWikis reside on personal computers or in the cloud, or are exchanged over email, in a manner similar to word processing documents and spreadsheets. As a single HTML file, or saved as an HTA file in Microsoft Windows (allowing corporate IE lockdown to be bypassed), TiddlyWiki can be useful in corporate environments where red tape or IT resources might prevent the use of a wiki that requires a more complicated installation.
