Zwischen
The in-between move for AI outputs

Intercept claims
before they ship.

Zwischen attaches a second AI to your agent to watch what it does in real time – and stop bad code, risky file changes, and made-up facts before they go out.

Coming soon. Early access is limited.

Built for enterprise teams running AI in production.
A red knight stands alone among dark chess pieces – the zwischenzug
The problem with "looks right"

AI systems don't fail loudly – they fail plausibly. And when multiple models agree, it often means they learned the same shortcuts.

Agreement is a red flag, not proof.

Zwischen introduces a deliberate interruption: a cross-model adversarial challenge that pressures a claim, exposes weak reasoning, and forces a harder standard before anything leaves your system.

Agents turn language into execution.
Consensus is cheap.
Verification is infrastructure.
Name

Zwischen comes from zwischenzug – the chess "in-between move" that disrupts the expected line. Insert the unexpected challenge at the moment it matters.

Be first to run it inline.

We're opening early access to a small number of teams building agentic systems where mistakes are expensive.

No demos. No deck. Just the list.
