AI Writing Coach for Freelancers

AI Prompts to Build This

Copy these build prompts into Claude, Cursor, or your AI coding tool. Create a free account to unlock the full research behind them.

1. 1. Project Setup

   Build the weekend MVP of "WordSmith AI": a membership for freelance writers whose core tool is a prompt gym that grades a prompt and rewrites it without losing the writer's voice.
   
   Stack: Next.js (App Router), TypeScript, Tailwind, Supabase (Postgres, Row Level Security, Auth with email magic link), Claude (Anthropic API) for the scoring. Deploy on Vercel.
   
   Tables (Row Level Security on: lessons are readable by signed-in members, progress and attempts by their owner):
   - lessons(id, module, title, video_url, prompt_examples_md, checklist jsonb, position)
   - lesson_progress(id, user_id, lesson_id, completed_at)
   - prompt_attempts(id, user_id, niche, assignment_type, user_prompt, voice_sample, result jsonb, created_at)
   Seed 3 modules: Research with Claude, Outline without losing voice, and Client disclosure scripts.
   
   Screens: /login, /lessons (the curriculum and progress), /gym (the prompt gym).
   Env vars (names only): NEXT_PUBLIC_SUPABASE_URL, NEXT_PUBLIC_SUPABASE_ANON_KEY, SUPABASE_SERVICE_ROLE_KEY (server only), ANTHROPIC_API_KEY.
   
   Do not build: billing, memberships or plans, daily limits, workshops, RSVPs or reminder emails, the community, 1:1 scheduling.
   Done when: npm run dev starts, you can sign in, and the three tables exist with Row Level Security on and three modules seeded.

2. 2. Core Feature

   Build the one feature that proves WordSmith AI: a prompt gym that makes a writer's prompts better and keeps their voice.
   1. POST /api/prompt-gym takes { niche, assignment_type, user_prompt, sample_paragraph_of_user_voice }.
   2. Ask Claude for strict JSON { score_0_to_100, issues: string[], improved_prompt, why_it_preserves_voice }. The rewrite must keep the writer's voice from the sample paragraph, not flatten it.
   3. Save every attempt to prompt_attempts.
   4. The page shows a score ring and a before and after of the prompt, with the issues listed.
   5. /lessons lists the seeded modules with their prompt examples and a checklist, and marks lessons complete.
   Rules: never rewrite the writer's sample paragraph. Explain every issue in one plain sentence.
   Empty state: with no attempts, show an example prompt that the writer can load and grade.
   Done when: a weak prompt scores low with specific issues and returns an improved prompt, a second grade of the improved prompt scores higher, and each attempt is saved.

3. 3. Landing Page

   Build a one-page landing site for WordSmith AI, a membership for freelance writers learning AI workflows.
   Headline: "AI won't replace writers who learn the workflows." One button: Join the waitlist.
   Sections: the problem (anxious freelancers and generic output), how it works in five steps (placement quiz, workflow modules, live workshops, the prompt gym, community and job wins), a sample prompt-gym result with a score ring, and an FAQ on voice, client disclosure and what the membership is not.
   Waitlist: store the email in a waitlist table in Supabase. No other service.
   Voice: encouraging, concrete and respectful of the craft.
   Done when: the page renders on a phone and a submitted email appears in the waitlist table.

4. 4. Branding Package

   Use a design or image tool for this one. A coding agent cannot draw a logo.
   Brand for WordSmith AI: a wordmark and an icon that suggest a pen nib and a spark.
   Colors: warm off-white, deep ink and one confident accent. Type: a refined serif for headings and a clean sans for the interface.
   Deliverables: wordmark, icon, a score-ring style, and one launch graphic.
   Done when: each deliverable is saved in one folder and the icon reads at 32 px.
