Description
Hi everyone I just created Deja, a tool that instead of only surfacing commands that start with what you've typed, suggest what you actually want to run. I built it because I was using zsh autosuggestions but got tired of typing the same commands again and again. So Deja predicts your next command from your history.Let me know what you think

Could you build this?
Yes This is a terminal autosuggestion plugin for Zsh that tracks command frequency and bigram/Markov transitions, easily written in standard shell scripting or Python/Rust.
