Case 01

Brand voice assistant

A creator or agency turns tone of voice into an AI app that drafts posts, replies, newsletters, and client copy without losing the brand style.

01

Before Prostir, the voice lives in approvals

The creator has a voice guide, strong examples, banned phrases, and approved client drafts, but every new post still waits for manual review.

  • The risky moment is not writing text; it is keeping the copy specific, sourced, and on-brand when a customer or team member asks for a new angle.
  • Prostir turns the guide, examples, and rules into app-owned knowledge plus a system prompt that knows when to draft, ask for context, or refuse unsupported statements.
02

What changes in the workflow

A client or teammate asks for a post, reply, newsletter, or landing block that must sound like the brand.

  • After-state
01 Scene

A client or teammate asks for a post, reply, newsletter, or landing block that must sound like the brand.

02 Intervention

The app collects channel, audience, offer, and length, then searches approved examples before writing.

03 After-state

The creator gets draft copy, a short critique, the voice rules used, and warnings for claims that need more source context.

03

After Prostir, the voice becomes a product

The app is easy to explain: upload examples, define rules, publish one assistant for the team or clients.

  • The customer no longer buys a prompt; they get a repeatable brand-voice workflow with access, knowledge, and review behavior.
  • For creators and agencies, the same assistant can become a paid add-on to strategy, content retainers, or client advisory.
04

Case roadmap

Now: upload the voice guide, approved examples, and unsupported-statement rules.

  • Next: add channel-specific review checklists for posts, replies, newsletters, and landing copy.
  • Later: package the assistant for clients or teams with access and pricing rules.
