HYPO.RAIL

Have your agents learn

AI can write. HYPO.RAIL lets it learn.

Posts, emails, landing pages, ads, or any other piece. HYPO.RAIL keeps what people did, and only sends a finding back when the test says it’s real.

How it works

Agents that ship content still start from zero.

An agent can produce the next piece in seconds. Then it forgets. The audience already answered, and that answer never reaches the next version.

HYPO.RAIL sits between your agents and the places the work goes live. It feeds back what happened, but only when the result holds up. Agents reach it through MCP, so they can use it themselves.

Before

Without HYPO.RAIL

  1. Agent creates
  2. It goes live
  3. People respond
  4. The agent forgets
After

With HYPO.RAIL

  1. Agent creates
  2. It goes live
  3. People respond

  5. The next run learns
The test

Only keep what’s real.

One good version can be luck. HYPO.RAIL runs a statistical check so the agent only learns from findings that hold up.

The setup

Talk to it through MCP.

Built for agents first. Add the MCP and they can run tests themselves. No extra dashboard for the team.

For teams whose agents already ship content. After this, six questions so we can tell if it’s a fit.
