Zeal

Zeal is an offline documentation browser: your personal reference library, searchable in an instant and available without a connection. Originally inspired by Dash, it supports the same docset format.

Download

Binary builds for Windows and other installation options are available on the download page. Windows builds require Windows 10 version 1809 or later.

How to use

After installing Zeal, go to File → Docset Library, select the docsets you want, and click the Download button.

Query and filter docsets

Limit the search scope by prefixing your query with a docset name and a colon:

cpp:vector

To search multiple docsets, separate them with a comma:

python,django:string

Command line

You can also start Zeal with a query from the command line:

zeal python:pprint
