The fascinate advantage

We win on two things —
innovation and trust.

Anyone can write a cron job that scrapes a URL. The interesting questions are how well does it learn and how honestly does it bill you. We took both seriously from day one.

{/* INNOVATION */}
01 — Innovation

An agent that learns from how you read.

Type /btw less rust drama, more allocator deep-dives right in the CLI. The patch lands in your preference profile as a strict JSON diff — never as freeform text the ranker could be tricked by. Smart routing picks Haiku for skims, Sonnet for the hard re-rank, Opus only when it pays for itself.

    {[ 'inline /btw learning', 'haiku · sonnet · opus routing', 'per-niche cached rerank', 'deterministic numeric scores', ].map(t => (
  • {t}
  • ))}
{/* TRUST */}
02 — Trust

Every job signed,
every dollar pre-quoted.

Before a single token leaves our dispatcher, we reserve credits inside a serializable Postgres transaction. Every job produces an Ed25519 receipt binding (prompt, content, output, criteria, timestamp) — the same hash on your machine and ours, forever replayable.

    {[ 'ed25519 signed receipts', 'hard-capped budgets', 'prompt-injection corpus', 'replay any past job', ].map(t => (
  • {t}
  • ))}
); } Object.assign(window, { Pillars });
