Bonfire Terminal vs AssemblyAI
AssemblyAI is a cloud-hosted speech API backed by a $50M Series C, priced per audio hour around $0.12-$0.37, using its proprietary Universal models and Anthropic, with a no-training-on-audio policy. Bonfire Terminal is a sovereign on-device agent instead: local Whisper transcription at no per-hour cost, your own LLM key at cost, one perpetual license.

Bonfire Terminal vs AssemblyAI: FAQ
Is AssemblyAI private?
AssemblyAI is cloud-hosted and states it does not train on user audio, but recordings are sent to its API for processing. Bonfire Terminal transcribes locally with Whisper on your device, so your audio never leaves your machine at all.
Is Bonfire Terminal cheaper than AssemblyAI?
AssemblyAI charges roughly $0.12-$0.37 per audio hour, which grows with volume. Bonfire Terminal is a one-time perpetual license with local Whisper transcription at no per-hour fee, so for regular transcription it is cheaper over time.
Can Bonfire Terminal replace AssemblyAI?
For local transcription and agent tasks, largely yes, using Whisper on-device. AssemblyAI is a developer speech API tuned for scale and accuracy with Universal models; Bonfire trades that API throughput for private, on-device transcription at no per-hour cost.
What can Bonfire Terminal do that AssemblyAI can't?
Bonfire Terminal transcribes offline with local Whisper, processes media on-device, runs a full agent and terminal, bridges to Telegram and WhatsApp, and uses any LLM key at cost. AssemblyAI is a cloud speech API without an agent interface or messaging bridges.
How do I switch from AssemblyAI to Bonfire Terminal?
If you used AssemblyAI's API for transcription, install Bonfire Terminal and transcribe with local Whisper instead. Add your own LLM key for downstream tasks, and your audio processing moves onto your device at no per-hour cost.
Does Bonfire Terminal work offline vs AssemblyAI?
Yes. Bonfire Terminal's local Whisper transcription and media processing run fully offline; only optional LLM tasks need connectivity. AssemblyAI is cloud-hosted with no offline capability, so it cannot transcribe without a connection.
