深言达意 is a writing assistance tool centered on "finding words and sentences": users first enter the meaning they want to express, then use search by meaning for words and sentences to find more fitting words, poetry, quotes, or sentences. It is aimed at people who need to quickly organize wording, supplement expressive material, and improve writing efficiency.
From the public page, the product supports Chinese-English bilingual use and provides vocabulary search capabilities such as definitions, synonyms, antonyms, and associative word queries. The page also shows that it is produced by 深言科技, and that the full web version can be used after logging in, while guest mode only shows part of the content.
