LEPTONIC SYSTEMS INC. RELEASES SURFJET AGENT 1.0
FINDS INTERNET ARTICLES; LEARNS VIA NEURAL NET TECHNIQUES

Leptonic Systems Inc. has announced that SurfJet Agent 1.0 has been
released and is available for purchase.

SurfJet Agent is an intelligent assistant that automatically searches the
Internet for you. It locates candidate articles (usually Web pages) using
Internet search engines, then pre-reads the article text, evaluating it
according to an "interest profile" you create, predicting your interest
level. Then it prioritizing the results to show you only the most
interesting articles it found. As you browse through the results, you can
correct its predicted interest level by moving a slider. Using neural
network techniques, SurfJet Agent can learn from this feedback to improve
its future performance.

SurfJet Agent requires a Macintosh computer with Internet access, Mac OS
7.1.5 or above and any popular Internet browser.

SurfJet Agent 1.0 has a suggested retail price of $79.95, but is available
for a limited time at the introductory price of $49.95 for electronic
delivery. Purchases are made via the Internet, and the package is delivered
by downloading it directly to your computer so it can be used immediately.
