The deal, in plain English.

Splitstream generates landing-page variants using Anthropic's Claude model, opens them as pull requests on your repo, and reads conversion data from your PostHog project to pick a winner. You merge any code change yourself.

You are the legal owner of the repo, Vercel project, and PostHog project you connect. You will review every PR before merging — Splitstream never merges code without an explicit click from a workspace owner or admin. You will not use the service to deploy code that violates third-party rights or applicable law.

We will keep your integration tokens encrypted at rest, limit our writes to opening pull requests on the repo you connected (no force pushes, no protected-branch modifications), and not train any model on your private repository contents.

The service is in closed beta. Features may change without notice. We may pause or revoke access for any account that abuses the service or strains the infrastructure. Beta usage is offered as-is with no SLA.

During beta, Splitstream is free. We will give 30 days' notice before introducing paid plans, and existing accounts will keep current functionality at a grandfathered price for at least 90 days.

You can delete your account from the dashboard at any time. We can terminate accounts that violate these terms or appear to be automated abuse, with as much notice as is practical.

To the maximum extent permitted by law, Splitstream is not liable for indirect, incidental, or consequential damages, including lost revenue from a deployed variant. Total liability is capped at fees paid to us in the prior 12 months — which during the beta is zero.

England & Wales. Disputes go to the courts of London first.
