Small Biz Copy Crafter

Context

Small Biz Copy Crafter is a micro-SaaS for copywriters who need to show more than polished output. It helps users create interactive, shareable portfolio experiences that explain the strategic thinking behind their work.

The product is built around the belief that good creative work is easier to trust when the judgment behind it is visible.

Problem

Most copywriting portfolios show final copy without the reasoning that made it work. That makes it hard for clients or hiring managers to evaluate taste, audience understanding, positioning, and strategic tradeoffs.

AI-generated copy can make the problem worse if it produces words without explaining the decisions.

What Shipped

• AI-powered copy generation with tone controls for clarity, warmth, confidence, and directness.
• Rationale panel explaining the strategic thinking behind generated copy.
• Audience check for clarity scoring and jargon detection.
• Brand voice profiles trained from writing samples.
• Portfolio sharing and hiring-manager view.
• Supabase auth, Postgres, RLS, Stripe payments, provider-agnostic AI layer, and tests for core AI/prompt behavior.

Architecture

The app uses Next.js 16, TypeScript, Tailwind, shadcn/ui, Supabase, Stripe, and a provider-agnostic AI layer that can route to OpenAI or Anthropic.

The product surface splits between dashboard workflows, public portfolio pages, documentation, admin views, and API routes for AI, drafts, payments, and sharing.

Key Decisions

• Center judgment, not generation. The product does not stop at copy output. It exposes rationale, audience fit, and strategic decisions.
• Build public sharing into the core loop. Portfolio and hiring-manager views make the artifact useful outside the dashboard.
• Keep the AI layer provider-agnostic. OpenAI and Anthropic can be swapped behind a consistent product workflow.
• Use docs as product surface. In-app guides explain brand voice, projects, portfolio sharing, and getting started so users can self-serve.

AI / Workflow Layer

The AI does not just produce copy. It produces and evaluates copy inside a workflow: draft, rationale, audience fit, brand voice, version history, and public presentation.

That distinction matters. The useful artifact is not only the paragraph; it is the proof that the writer understands why the paragraph works.

Sample Artifact

A strong portfolio item combines:

• Final copy.
• Strategic rationale.
• Audience fit notes.
• Brand voice context.
• Shareable public view for a hiring manager or client.

The product makes the invisible parts of copywriting visible.

Constraints

• User writing samples and generated work need privacy boundaries.
• Paid features require Stripe lifecycle handling.
• Public portfolio pages need to be shareable without exposing private dashboard data.
• AI output needs to support the user's judgment, not replace it.

Tradeoffs

• Rationale adds friction compared with a plain generator, but that friction is the differentiated value.
• Public sharing creates marketing leverage, but it requires careful access boundaries around private drafts and samples.
• Provider abstraction adds engineering work, but it protects the product from being tied to one model vendor.

What I Would Improve Next

• Add richer examples of public portfolio pages.
• Add a stronger onboarding path from first draft to first shared portfolio artifact.
• Add analytics for which portfolio sections hiring managers actually inspect.
