Electrum Airgap for Etherium

Hi all,

I am referring to cold storage wallets like with Electrum for Bitcoin. You can have a permanently offline and airgapped computer that signs transactions. You then bring the transaction back to your online computer.

Does anything like this exist for ethereum? I know that airgap wallet does this, but I'm looking for something that can store my private keys on a laptop/PC.

Thank you so much.
