I like using atuin[1] but the capture mechanism here's pretty convenient! Cool idea. May give it a try

If Happen you do, I'd love to read what you think, or if you have any suggestion.
Thanks a lot for your time.
ive certainly had this problem before, but id really like for such a tool to figure out how the local context is slightly different
eg. im reading logs across 3 regions, NA, EU, FE
i go figure out my command for NA, which then gets forgotten, but i want to run it against FE next, of which everything is exactly the same except one chunk of the path
/../NA/../somefile
vs
/../FE/../somefile
id be nice to keep the command for the future, but even nicer of it could figure out on its own that NA needs to swap to FE

The core mechanism wants to be a "zero-touch" capture that happens at the connection gateway level. Instead of installing logging agents or scripts on every target machine, the tool reconstructs your terminal sessions from raw recording files generated by the proxy you use to connect. This "in-flight" capture means you get a high-fidelity log of every keystroke and output without ever having to touch the configuration of the remote host. It’s a passive way to build a personal knowledge base while you work.
To handle the reality of context-switching, the tool is designed with a "multi-tenant" architecture. For an individual engineer, this isn't about managing different users, but about isolating project contexts. It automatically categorizes history based on the specific organization or project tags defined at the gateway. This keeps your work for different clients or personal side-projects in separate buckets, so you don't have to wade through unrelated noise when you're looking for a specific solution.
In true nerd fashion, the search interface stays exactly where you want it: in the command line. There is no bloated web UI to slow you down. The tool turns your entire professional history into a searchable, greppable database accessible directly from your terminal.
