What are the benefits of using Dr.Explain?
A key factor in documentation effectiveness is how easily users find information. If users spend too much time searching for answers, they can lose interest and abandon the product. But when information is quick to locate, it creates a positive experience and increases the product's value.
A keyword index transforms your guide into a truly useful tool by letting users instantly find topics using familiar terms.
Quick access to information. Users can jump directly to relevant topics by selecting known words or phrases — no need to browse the table of contents or use search.
Multiple entry points assign several keywords to the same topic, increasing the chances users will find it through different terms.
Better accessibility. The index is especially helpful for less technical users, who can navigate more easily using simple keywords they already know.
What type of users is Dr.Explain suited for?
Dr.Explain simplifies the most challenging parts of documentation — planning your project structure, creating annotated screenshots, and exporting to the right formats. Try this help authoring tool if you need:
- a user-friendly text editor with spell checking for multiple languages;
- a free trial before making a purchase decision;
- cloud-based collaboration for author teams;
- a desktop application rather than a SaaS platform;
- single-source export to multiple output formats.
Users about working with the keyword index in Dr.Explain
"The features I liked were the Menu, Index and Search. It is very clean and easy for my customers to find just the section they need. I also like that they can download a PDF of the guide but not a lot of customers do that because the main User Guide is over 400 pages! It is very easy to update when I add new features".
Margaret Messick,Owner/Database Designer
