Why my own key?
No middleman. You pay your provider for what you use.
How much?
The app is free. Your only cost is the AI model you plug in, billed by your provider. Example with Claude Haiku 5.5: filing a note costs well under €0.01, and a question €0.0005 to €0.0035 depending on how many notes you have. So 100 questions cost roughly €0.05 to €0.35.
Are my notes read?
Only by your AI provider, to file or find them.
Windows?
Not for now.
