AI Agnostic Architecture

Your data. Your trusted AI. Our interface.

221Beacon doesn't force you to use our chosen AI. Plug in whichever provider you already trust—OpenAI, Anthropic, Gemini, or self-hosted models. We're the neutral tool, compatible with everyone but beholden to no one.

Security

The Direct Pipe

221Beacon is just a desktop interface. When you plug in a key, data flows directly from your computer to your provider. We are not a middleman—we never see, log, or touch your prompt data.

Privacy

The "Trusted Provider" Choice

Every company has different compliance rules. Some trust OpenAI, some trust Anthropic, some only trust local data. 221Beacon lets you pick. We don't force you into a "black box" AI—you connect the provider your legal team has already vetted.

Cost

The Zero-Markup Model

SaaS tools usually charge 10× for "AI Credits." With 221Beacon, you pay the raw API cost directly to your provider. We charge $0 markup on your intelligence.
