Why it exists

Edit product copy and identify vague claims, unclear calls to action, and unsupported language before publication.

Generic terminals, provider APIs, and custom prompts can cover parts of the work, but the caller must supply permission limits, output requirements, failure handling, and usage accounting.

Connection and contract

Connect from an MCP-aware client with an account-scoped Monarchic key. The hosted route checks access, runs the named product contract, and records the operation on the account receipt.

The product-specific schema defines the inputs and outputs used by clients and downstream automation.

Current limits

The review identifies language problems; it does not verify product claims or publish changes.

Requires an authenticated, entitled account. The call reads only the copy in the request.

Flag vague claims and unclear calls to action
Return review findings separately from rewritten text
