Honest by design

Is your data a fit for AT-1?

Drop in a sample and get an instant, honest report — the entropy floor nobody can beat, what general compression already achieves, and whether AT-1 has a real edge on your data. Two of the things we test, we tell you to skip. For free.

STRONG FIT

There's a domain edge beyond general compression — genomics, sensor/time-series, and other rule-governed data where AT-1 models the domain, not just the bytes. A pilot quantifies the exact win.

CAPABILITY FIT

About the same size as a good general compressor — but queryable in place without decompressing, with every byte SHA-256-verified. The edge is capability, not a smaller number.

PASS

Already at the entropy floor — random, encrypted, or already-compressed. We'll tell you there's nothing to gain, for free, rather than sell you a pilot that can't win.

Why we lead with the floor

Most vendors quote you a compression ratio. We start with the Shannon floor — the bits-per-byte that nobody, including us, can beat — and show that a standard general compressor is usually already sitting on it. AT-1 does not beat general compression on raw bytes, and we say so. Our edge is a model of your domain(the structure general compression can't see in variant data or a sensor stream) or a capability (query the archive in place, verified integrity) — never byte-cruft. The audit runs entirely in your browser; only a handful of summary numbers are ever sent.

Got a STRONG FIT? The next step is a pilot on your real data.
