Bonfire Terminal vs ProWritingAid
ProWritingAid is a cloud-hosted writing editor, freemium up to about $120/yr, and it states it does not train on your text. Bonfire Terminal takes privacy further: a sovereign on-device agent where nothing leaves the device at all, with a bring-your-own-key model at cost and a single perpetual license.

Bonfire Terminal vs ProWritingAid: FAQ
Is ProWritingAid private?
ProWritingAid says it does not train on user data, which is reassuring, but it is cloud-hosted so your text is uploaded for analysis. Bonfire Terminal processes everything on-device, so your writing never leaves the machine and no server sees it.
Is Bonfire Terminal cheaper than ProWritingAid?
ProWritingAid runs on a subscription up to roughly $120/yr, recurring indefinitely. Bonfire Terminal is a one-time perpetual license with bring-your-own LLM keys billed by providers at cost with no markup, so lifetime spend is typically lower.
Can Bonfire Terminal replace ProWritingAid?
Partly. Bonfire's on-device LLM can draft, rewrite, and critique text privately, but it lacks ProWritingAid's specialized grammar reports and style scoring. For general writing help kept fully local, Bonfire fits; for dedicated editing analytics, ProWritingAid is purpose-built.
What can Bonfire Terminal do that ProWritingAid can't?
Bonfire runs entirely on-device, adds Telegram and WhatsApp bridges, local Whisper speech recognition, and local media processing, and is a full agent and terminal, not just a writing checker. ProWritingAid is cloud-based and limited to editing text.
How do I switch from ProWritingAid to Bonfire Terminal?
There is no document lock-in with ProWritingAid, so just install Bonfire Terminal, add your own LLM key, and paste or point it at your writing to get private, on-device drafting and revision.
Does Bonfire Terminal work offline vs ProWritingAid?
ProWritingAid offers only partial offline use and leans on the cloud. Bonfire Terminal is on-device, so Whisper transcription and local media tasks run offline; LLM requests need internet but go straight to your own provider.
