A different approach: Bonfire Terminal

Smartlead.ai runs in the vendor's cloud — your data is processed on their servers, and you pay every month for as long as you use it. Bonfire Terminal is a different kind of tool: an AI agent that runs as a desktop app on your own machine. No cloud, no API credits, and nothing you type leaves your computer.

To be straight with you: it is not a drop-in replacement for Smartlead.ai, and we are not going to pretend it is — they do different jobs. It is worth a look if the cloud-subscription model itself is what you want out of, or if you want an AI agent that works privately and offline. If Smartlead.ai is doing its job for you, keep it.
