Alpheios Reading Tools Version, February 2019

This is a minor release. The Alpheios extensions now issue events (Alpheios_Active and Alpheios_Inactive) that a site or page can use to detect when the user has enabled or disabled it. We have also added inflection tables for a few more Latin irregular verbs.

Alpheios Reading Tools Version, December 2018

This is the first release of the Alpheios Reading Tools for Safari. The Chrome and Firefox extensions have been updated as well.

In addition to the support for Safari, the following features are included in this release:

  • The Inflection Table Browser has been moved to its own tab, separate from inflection tables for query results.
  • Issues with the Alpheios popup and panel styles being affected by the underlying page styles have been fixed.
  • Improved handling of panel state upon page navigation.
  • Additiional Latin irregular verb inflection tables.

Alpheios Reading Tools Version Beta Patch Release, November 2018

This patch to the 2.0.3 Beta release includes a variety of fixes and improvements to the Greek Inflection Tables.

Alpheios Reading Tools Version 2.0.3 Beta Release, October 2018

This is the first Beta release of the Alpheios Reading Tools for Chrome and Firefox.

In addition to greater overall stability across a wide variety of sites, the biggest focus of this release is the completion of the Latin and Greek Inflection tables. This release now has near parity with the functionality provided in Alpheios Version 1 and we have improved upon that with greater accuracy, both in the content and when matching into the tables on the forms identified by the morphologic analyses.

If you are still using the old Version 1 Alpheios Firefox Extensions, we encourage you to upgrade now to this newer version.

Various new features and bug fixes are included in the release, the most important being the following:

  • Lookup of user-supplied words
  • Inflection table browser
  • Greek inflection tables
  • Latin inflection table additions and corrections
  • Enhanced inflection table matching
  • UI Design improvements
  • Improvements to Latin morphological information
  • Improvements to Arabic morphological information
  • Ability to adjust display font-size
  • Support for Google Drive documents
  • Works with the Scaife Viewer version of the Perseus Digital Library

Alpheios Reading Tools Version 2.0.2 Alpha 2 Release, March 2018

This release adds the ability to use the escape key to close the Alpheios popup and panel as well as some architectural code improvements.

Alpheios Reading Tools Version 2.0.1 Alpha Release, February 2018

This release of the Alpheios Reading Tools for Chrome and Firefox is an alpha version, released with these goals in mind:

  • To provide a replacement for the original Firefox extensions.
  • To request user feedback on the design and functionality of the new version while we are still in early stages of development.

We encourage you to install and test the tools and offer feedback on what works, what doesn't and what you would like to see added or improved. Below are lists of the basic functionality which should be working now, known issues, and our dreams for future releases

See our instructions for Getting Started. Please send all feedback to

Known Issues and Requests for Feedback

  • Dynamic positioning of the popup near the word selection may not be optimal on all screen resolutions, particularly on words which are near the edge of the display. You can choose to set the position to fixed in the Options panel as a fallback.
  • We are actively seeking input on the best new user interface design for Alpheios. The current design is provisional and we expect we may change it significantly in coming releases. We need feedback from users to know what would work best.
  • The Latin inflection tables are missing irregular verbs and the ability to browse the tables independent from word lookups.
  • The Greek and Latin grammar displays need better navigation support and an updated design.
  • Automatic identification of the language of a page only works if the language has been explicitly identified in the markup. This should be improved upon.
  • The Persian functionality is only experimental. We need a new morphological analyzer in order to provide more complete results.

Features targeted for the Beta Release

  • Addressing known issues
  • Updated user interface design
  • Greek inflection tables
  • Inflection table browse functionality
  • Support for treebanks and aligned translations
  • User accounts and individual word lists
  • Release of the Alpheios component libraries for reuse

Longer term Roadmap

We have big ambitions for Alpheios. We list just some of those here. Eventually we hope to support many additional features (such as commentary and annotation). We hope to provide full multilingual support for the interface and supporting resources, and also to add reading support for additional languages such as Hebrew, Syriac and Coptic. We want to offer more resources (lexicons, grammars, treebanks, translations, wordnets, etc.) for the existing languages, and to allow users to supply and share their own resources for specific languages and texts. We want to link to the ever increasing array of already existing-community provided tools and services for these languages, and to allow users the ability to customize the interface and resources for language learning according to their own needs and preferences. We will provide mobile applications and learning games to accompany the browser extensions. We will also explore the addition of audio and visual aids to the texts.
