Bonfire Terminal vs Synthflow AI: FAQ
Is Synthflow AI private?

Can Bonfire Terminal replace Synthflow AI?
Not for automated outbound voice calls. Synthflow AI specializes in cloud phone agents with SMS. Bonfire Terminal is a personal on-device terminal, so it replaces private AI tasks rather than a voice-automation platform.
What can Bonfire Terminal do that Synthflow AI can't?
Bonfire Terminal runs offline, keeps data on-device, transcribes with local Whisper, processes media locally, and bridges Telegram and WhatsApp without key markup. Synthflow AI is a cloud voice builder with proprietary speech and marked-up keys.
How do I switch from Synthflow AI to Bonfire Terminal?
Migrate only if your goal is private AI rather than voice campaigns. Install Bonfire Terminal, bring your own key with no markup, and connect WhatsApp; you gain on-device privacy but not automated phone calling.
Does Bonfire Terminal work offline vs Synthflow AI?
Bonfire Terminal works offline with local Whisper and models. Synthflow AI has no offline capability because it is cloud-hosted, so its voice agents require a connection while Bonfire runs on your device.
