Alpheios builds evidence-based, open-source software to support worldwide study of classical languages and literatures. The Alpheios Reading Tools enhance any text you read in the browser by adding clickable access to dictionary entries, morphological analyses, inflection tables and grammars for any Latin or Ancient Greek word. A subset of these resources are available for Classical Arabic and Persian. Personal vocabulary lists and learning games will be added in coming releases.
The Alpheios tools can be installed as extensions to the Chrome and Firefox browsers (further instructions here). Support for the Safari browser and mobile devices is under development.
Other Alpheios modules include a treebank editor and a translation alignment editor.
