Show HN: Deja – zsh that predicts your next command from sequence patterns

https://github.com/Giammarco-Ferranti/deja
2•giammiferr•2h ago
Deja runs a local sqlite daemon over a unix socket, scores your history with frecency + directory affinity and uses Markov style sequence prediction to suggest what you’ll type next.

Pls let me know what you think. I'm still improving the tool and open for feedbacks. :)
