Real output for the Ledgerly example — nothing retouched.
### Business-specific entities
Create tables for the following entities (with appropriate relationships):
Client, Invoice, LineItem, Expense, Receipt, PaymentReminder, Report
For each entity:
- Add `id`, `created_at`, `updated_at`
- Add appropriate foreign keys
- Add indexes on frequently queried columns
The template knows your entities by name. The columns, types and relations are left to your agent.

Pricing questions
What does the Pass add to the spec?
The deep spec. The free spec is written by a template: it names the entities ("create tables for Client, Invoice… with appropriate relationships") and lists generic rules. The deep spec is written by Claude for your project: 15 to 30 tables with their columns, types and relations, 40+ routes, acceptance criteria and edge cases per feature, and a build plan in milestones sized for one agent session each. It is appended to the spec and to every file of the pack.
Is the free spec still useful?
Yes: 2 specs and 3 AI drafts without an account, all project types, the full 8-file pack. It gives your agent the stack, the pages, the security and legal checklist. What it leaves to the agent is the design itself — which is where agents improvise.
7-day Pass or Pro?
The Pass is a single $5 payment: 5 deep specs and unlimited specs for 7 days, for the week you are scoping a project. It does not renew; buy another one later and the days add up. Pro at $9/month (10 deep specs a month) is for agencies and people who start projects every week.
Can I cancel?
Pro: cancel from your account at any time and keep access until the paid period ends. The Pass is a one-time payment with nothing to cancel.
Do I need an account to pay?
No. Pay with your email; the account is created for you and you get a link to set a password. Everything you generated in this browser moves to it.
Do I keep my specs if I stop paying?
The spec text and export files are yours the second you download them - they sit in your repo, not on our server. Your saved history in the dashboard stays readable.
Which builders does the output work with?
The spec pastes into Claude Code, Cursor, Bolt, v0, Windsurf, Replit and Lovable. The export pack drops native rules files for Claude (CLAUDE.md), Cursor (.cursorrules), Windsurf (.windsurfrules) and Copilot (copilot-instructions), plus a shared AGENTS.md.
Is my payment secure?
Checkout runs on Stripe. Card details go straight to Stripe - we never see or store a card number.
