## History

The developer of the Multitran software is Andrey Pominov, Moscow. Currently, Multitran is one of the largest and most popular web dictionaries in Russia. Every day, over 90 thousand people visit Multitran.ru, and over 1.5 million search requests are processed.
The Multitran base was created by scanning a wealth of paper dictionaries and combining all the translations in one database.
The website historically had a very low budget: according to Multitran's history page, a CPU paid only one dollar served over 4 million hits, and the site had issues with networking and electricity works around the webmaster's house in 2001 and 2002, as well as with growing traffic in 2002–03.
Multitran users arrange offline meetings from time to time, the so called pow-wows. Such pow-wows were held in Moscow, St. Petersburg and Kyiv.
In May 2019 the Multitran's website was redesigned, with a gradual transfer of all user-generated data to the new website.
In early June 2023 the website announced that its server has been transferred to Finland.

## Advantages and disadvantages of Multitran

The huge volume of the base is both an advantage and a disadvantage because:
* Multitran may offer well over 100 translations for a word, which complicates the task of choosing the right equivalent for beginning language learners, though it comes very handy for language professionals.
* Search results often give duplicate translations of a term for various disciplines.
* Multitran may give very narrow meanings of a term, suitable only for very limited contexts.
* Multitran has a feature enabling users to check the equivalent translations, but checking each and every term may require dozens of man-years of work. Every registered user can issue a warning about identified mistakes, so until a mistake is corrected, it remains marked accordingly. Multitran users have reported about 8000 mistakes using this functionality, and most of them have been corrected. Thus, users not only add their own terms (added by users are more than 180 thousand words and phrases), but also help to clean the database from mistakes.
* The feature allowing every registered user to contribute is an advantage, but it also carries the risk that mistranslations are added to the database, because they are added arbitrarily by Multitran users and depend on the level of the contributing individual user's knowledge, which may not be up to the mark.
