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.

Filter by common or rare words. ## Keywords IWL displays the most semantically important words in your document. Great for SEO, summaries, or finding the hidden themes in your drafts. ## Sentence Rank Spotlight your strongest lines. Using vector analysis, IWL ranks your sentences by informational weight—so you can find the most important lines fast. Ideal for editing, summarizing, or structuring arguments. ## Outline IWL auto-generates outlines from your headings and structure, giving you instant navigation and a birds-eye view of your doc. ## Links Every link, one view. See all your hyperlinks extracted from the document in a single glance. Useful for checking sources, citations, or cleaning up drafts. ## Comments All your side notes in one place.

Look up word definitions, synonyms, and usage without breaking your writing flow. It’s fast, built-in, and never intrusive. It also shows pictures. ## Read Aloud - Let your writing speak. IWL’s text-to-speech helps you catch awkward phrases and polish your rhythm by hearing your text performed aloud. Choose from a variety of voices. ## Export Beautiful output in every format. Export to PDF, styled HTML, or Word documents with zero formatting headaches. ## Markdown Preview No more guessing what your Markdown will look like. IWL renders your document with elegant typography and layout—automatically. It’s fast, accurate, and great for checking blog posts, docs, and articles.

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.
