Build idea

Build an AI writing agent around your own examples and editorial rules. Ask Builder for the voice you want, test a draft and explain what to change. This is an worked examples; you review the text before publishing.

Before you read

What gets published

Best for

Solo founders, consultants, creators, copywriting agencies, and content companies that repeatedly rewrite generic AI drafts to restore a distinctive voice.

A truthful build path

Use your own authorized material and validate the behavior before anyone else relies on it.

  1. 01
    Collect representative writing samples.

    Remove confidential material and keep only content you own or may use.

  2. 02
    Define the voice.

    Record tone, sentence rhythm, preferred hooks, banned phrases, audience, and topics.

  3. 03
    Build and test the agent.

    Try normal requests, edge cases, and counterexamples; revise the instructions when the voice drifts.

  4. 04
    Choose access and publish only when ready.

    A published slug receives https://{slug}.ai.prostir.build. Stripe Connect can support one-time or subscription sales; Rozetka Pay supports one-time sales only.

03

Voice rules as knowledge

Use your own authorized material and validate the behavior before anyone else relies on it.

  • docvoice-guide.mdVoice rules as knowledge
  • docbanned-phrases.mdThe author remains responsible for facts, claims, permissions, tone, and final approval.
  • docwriting-samples.mdRemove confidential material and keep only content you own or may use.
  • docreview-checklist.mdThe agent can make first drafts more consistent; it cannot guarantee a perfect imitation on the first attempt.

What this example does—and does not—promise

  • The agent can make first drafts more consistent; it cannot guarantee a perfect imitation on the first attempt.
  • The author remains responsible for facts, claims, permissions, tone, and final approval.
  • A published agent uses its actual saved slug; this page does not claim that a particular voice agent is already live.
  • ChatGPT, Claude, Claude Code, or another client can use the MCP endpoint only where that product and account support the required connector and authentication.
