ʻO Artha kahi thesaurus maʻalahi e kālele ana i ka hoʻohana kiʻekiʻe, me ke kālepa ʻole ʻana i ka maʻalahi a me ka maʻalahi o ka hoʻohana. Loaʻa iā ia nā hiʻohiʻona ʻokoʻa e hoʻonui ai i kona hoʻohana:

• WordNet – Artha harnesses the extensive & in-depth database provided by WordNet. Unlike other dictionaries which goes on-line for every single lookup, Artha works completely off-line; thanks to WordNet for its excellent and cognitive database.
• Huli kiʻi wela - Ke paʻi ʻoe i kahi kī wela i hoʻonohonoho mua ʻia, ma hope o ke koho ʻana i kekahi mau kikokikona ma kekahi pukaaniani, e puka mai ʻo Artha me nā wehewehe o ke koho i nānā ʻia.
• Huli ʻŌlelo maʻamau - Ke ʻike maopopo ʻia kahi huaʻōlelo I.e. ʻAʻole maopopo i ka mea hoʻohana i kāna ʻōlelo ʻana a i ʻole ʻike ʻia ka hoʻomaka/hope wale ʻana a i ʻole ke ʻike ʻia ka helu o nā huaʻōlelo; hiki i kekahi ke hoʻopale a hōʻemi i ka huli ʻana me ka hoʻohana ʻana i ka ʻōlelo maʻamau e ʻimi ai i ka huaʻōlelo i manaʻo ʻia.
• Nā leka hoʻomaopopo - hiki iā Artha ke hōʻike i nā leka passive (balloon tips) ma kahi o ka puka aniani o ka noi e puka mai ana, i hiki iā ʻoe ke hoʻomau i kāu hana, me ka pau ʻole. (e like me ka heluhelu, kākau, etc.)
• Manaʻo Manaʻo - Ke nīnau ʻia kahi huaʻōlelo kuhi hewa, hāʻawi ʻo Artha iā ʻoe i kāna mau manaʻo hoʻokūkū kokoke.
• Pili i ka Sense Mapping - ʻO nā huaʻōlelo pili e like me nā huaʻōlelo like, antonyms, etc. i hōʻike ʻia he nui. ʻAʻole paha ʻoe i ʻike i ke ʻano o kahi huaʻōlelo e pili ana i ka palapala ʻāina pili. Ma Artha, ke koho ʻoe i kahi pili, ua ʻōwili ʻia kona wehewehe ʻana a kuhikuhi ʻia no ka maʻalahi o ka hoʻomaopopo ʻana.

No kekahi huaʻōlelo, ʻo nā ʻohana pili i hōʻike ʻia e Artha e pili ana i nā Synonyms, Antonyms, Derivatives, Pertainyms (Related Noun/Verb), Attributes, Similar Terms, Domain Terms, Entails (he aha ka huaʻōlelo e hana ai), Causes (he aha ke kumu o ka huaʻōlelo), Hypernyms (he ʻano o), Hyponyms (ʻano) a me nā ʻano). No ka ʻike hou aku e pili ana i kēlā me kēia ʻano o nā ʻohana, kaomi ma luna no ka wehewehe a me ka laʻana. I ka wā i hoʻokuʻu ʻia ai, noho ʻo Artha ma luna o ka pā ʻōnaehana a nānā i ka paʻi hoʻohui kī wela i hoʻonohonoho mua ʻia. Hiki iā ʻoe ke koho i kekahi kikokikona ma kekahi puka aniani, a kāhea iā Artha ma ke kaomi ʻana i ke kī combo. Ma muli o ke koho koho, ʻo Artha me ka pop-up me ka huaʻōlelo nānā-up a i ʻole e hōʻike i kahi hoʻolaha passive o ka wehewehe nui loa o ka huaʻōlelo i ʻimi ʻia, mai ka pā ʻōnaehana.
