Lizzandra is troubleshooting software that uses AI to diagnose and fix issues on your machine! A strict rules engine lets her run a carefully vetted set of commands to keep your system safe. Beyond that, she can detect silent crashes, research known solutions online, and download and install any software needed to resolve your issue.

Try the harness
Same starting rules as the app (Windows or macOS profiles), including which folders she can only read, and which she cannot touch. Edit the list, try a command, see allow, ask, or block. Nothing runs in your browser. If a dangerous line is allowed, or a safe one is blocked, use Report on that page.
Questions
Straight answers about what runs where, and what the harness does.
Is Lizzandra free?
The app is free. You pay OpenRouter for the AI, with a key you create. There is no Lizzandra account, and nothing in the app to subscribe to.
What do I need?
Windows, and an OpenRouter API key. You paste the key in the app. This website does not need a login.
Can Lizzandra run dangerous commands if there's no rule for it?
No. Every command not covered by its own rule falls back to a default rule, which you control. Set it to auto-block, AI-vetted, ask first, or auto-accept. The same applies to the parameters sent with a command: any parameter without its own specific rule also falls back to that default. Commands and parameters with their own specific rule use that instead. By default, user approval is required as the base rule.
Are some commands blocked no matter what I set?
Yes. She cannot run PowerShell, Python, Node, or similar scripting tools. Formatting a disk and a few other destructive commands are blocked the same way.
Can she read my passwords or keys?
No. SSH keys, cloud credentials, and saved browser logins are blocked on every profile, including just listing them. On Normal and Strict, common system folders are read-only: she can look, not write. Relaxed does not add that system-folder limit.
What leaves my computer?
Chats, files you attach, command output, and pages she reads go to OpenRouter, not to us. She is not copying your whole disk. Crash reports stay on your PC unless you ask her to investigate one. The app may check this site for updates.
Does she run in the background?
While the app is open, she reads crash reports Windows already saved and lists them under Events. She does not send those to us. Start with computer only means she launches at login and stays in the tray when you close the window. Quit from the tray to stop her.
Why does Windows block the installer?
It is not signed with a paid Microsoft certificate, so Windows warns. That is about the download, not about what she is allowed to run. Get it from this site, then More info, then Run anyway.
Can she download and install software?
Only if you approve the download. The file goes to a Lizzandra folder in Downloads. Running it is a separate command and still has to pass the rules.
Mac or Linux?
Public download is Windows only.
