Primarily, the project is aimed at helping people who:
- have difficulty/concerns with securely caching physical seed backups (evil maid attack)
- want to memorise their seed words but struggle to do so
- want to carry their seed words with them at all times
- have limited access to trusted 3rd parties
- live in areas of conflict, warzones, etc.
- regularly travel or move around
- have no permanent fixed abode.
In practice, though, it can be used by anybody who wants to more easily and more reliably commit their Bitcoin seed words to memory.
