Why this matters right now

Fable 5 is Anthropic's most intelligent model — a tier above Opus. During the promo it's included in Claude Pro and Max subscriptions (up to 50% of your weekly usage limit, nothing to activate).

When the promo ends, Fable 5 moves to prepaid usage credits: $10 per million input tokens and $50 per million output tokens. A serious build session — a full app, lots of iterations — easily burns 2–5M tokens. That's $100–250 of usage you get for $0 right now.

So the strategy is simple: spend the free window on builds that keep paying you after it closes. Here are the five.

1. Clone the SaaS subscription you resent most

What: Rebuild one simple paid tool you use — a CRM-lite for your leads, an invoice tracker, a booking board, a link-in-bio page — as your own app.

Why now: Most $30–50/mo tools you actually use maybe 10% of. Fable 5 can one-shot a working internal tool in a session that would cost real money at API prices. Cancel one $40/mo subscription and you've "earned" $480/year from one evening.

How:

  1. Pick ONE tool. The rule: the subscription that annoys you most every time the charge hits.
  2. List the 3–5 features you actually use. Ignore the rest — that's why yours will be better.
  3. Prompt to start:

I pay for [tool] but only use these features: [list]. Build me a single-file web app that replaces them. My data: [describe]. Keep it simple — no login, no database, local storage is fine for v1.

  1. Iterate 3–4 rounds, then use it for a week before adding anything.

Time: one evening.

2. A content engine that writes in YOUR voice

What: A reusable Claude skill/workflow: drop in one long video transcript → get 10 short-form scripts, captions, and hooks that sound like you, not like AI.

Why now: Teaching a model your voice takes heavy lifting — analyzing your best content, extracting patterns, testing outputs. That's exactly the deep-reasoning work worth doing on the strongest model while it's free. Once the skill is written, it runs fine on cheaper models forever.
