About

Save the storage bill. Keep every byte. Query it anyway.

AT-1 (TinyFiles) is a structure-aware, verified-lossless compression system with a capability no general tool offers: query your data while it stays compressed, and still reconstruct the exact original file.

We don't compete on a contested ratio number. We win on capability (queryable + byte-exact), economics (a recurring storage saving with sub-day payback), and distribution (a tiny decoder that runs everywhere). The core method is the subject of a pending patent.

Built by Dylan Wolpe

AT-1 grew out of a research program on compression as a structure detector — published open-access, not just marketed. The method and its exact functional-dependency engine are described in two papers you can read in full:

Judge us on bytes, not testimonials

We have no customer logos to show you yet, so we don't pretend to. Instead we give you what a logo can't:

  • • Every benchmark runs on a named public dataset and prints its own LOSSLESS: True/False gate — reproduce them yourself.
  • • The decoder is open source (Apache-2.0), so nothing locks you in — anyone can open an AT-1 file forever.
  • • The CLI is one command away: npm install -g @tinyfiles/cli.
