CALO Express

CALO Express offers learning-enhanced desktop search across files, contacts, appointments, emails, and news articles. In addition to keyword search, natural language query helps you find exactly what you are looking for (e.g. "Find email from bob about networking"). CALO Express also lets you search meeting transcripts created using CALO Meeting Assistant.

CALO Express helps you find the slides you need and assists in discovering other versions of an existing slide.

CALO Express's PrepPak feature will gather files, emails and other information it thinks might be valuable for you as you prepare for an upcoming meeting, seminar or conference.

After you subscribe to news feeds, CALO will learn your preferences about which articles are most interesting to you and highlight those it believes you will find the most valuable. CALO will also apply this learning to suggest additional news sources you might want to subscribe to.
