Generating… usually about a minute.
What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

Assemble professional documents in minutes — from reusable clause libraries. SIMBLE is a document assembly tool that lets you build documents from reusable, customizable clauses. Whether you're drafting contracts, leases, solicitations, or any structured document, SIMBLE helps you work faster and stay consistent. How It Works Organize your clauses into libraries — for example, Contracts, Leases, or Solicitations. When you need a new document, simply pick the clauses you need, fill in the details, and export. Key Features • Clause Libraries — Create multiple libraries to organize clauses by type, project, or client. Switch between libraries with a tap. • Smart Variables — Add placeholder fields to your clauses using five input types: Text, Date, Time, Select, and Multi-select. Variables are filled in through intuitive pickers and automatically inserted into your document text. • Drag & Drop Document Builder — Long-press a clause to drag it into your document, or tap to add it instantly. Reorder clauses with a swipe. Add an entire library of clauses at once. • Live Preview — See your document come together in real time as you fill in variables. Oxford comma formatting is applied automatically for multi-select fields. • One-Off Edits — Make document-specific changes to any clause without affecting the original in your library. Easily revert edits when needed. • Export & Share — Copy your finished document to the clipboard or share it directly using the system share sheet. • Custom Categories & Colors — Assign categories and colors to your clauses for quick visual organization. Customize or add your own categories in Settings. • Auto-Save — Libraries, clauses, documents, and all your edits are saved automatically between sessions. Built For • Legal professionals drafting contracts and agreements • Procurement teams assembling solicitations • Property managers creating leases • Anyone who repeatedly assembles documents from standard language No account required. No cloud storage. Your data stays on your device.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
