# Text expanders
Text expanders are applications that increase writing productivity, by replacing specific character sequences with others. For instance, using tools such as [espanso](https://espanso.org/), it's possible to replace ":site" by "https://dsebastien.net". Such replacements can go as far as replacing a few characters by an entire book.
This boosts productivity and also help to replace complex URLs and other data. For instance, I have text replacements configured for:
- My e-mail signature
- My presentation
- The URLs I mention most often (e.g., Website, newsletter, products, etc)
- ...
