The program can be downloaded as PolyEdit Lite, which is free for home use. A paid-for version is also available.
PolyEdit can compress and encrypt documents saved in its native Enhanced Text Format (*.etf), using the Blowfish and SHA-1 algorithms. It can embed OLE objects and images (the latter including PNG files, JPEGs, BMPs, GIFs, and icons). The program supports basic tables and multiple columns, as well as hyperlinks, and features syntax highlighting for C++ and other programming languages. Another feature is PolyEdit's email client, which has a simple address book with an import feature.
