Feature spec
Goal: Send a clear invoice after finishing a job.
- Add a client, line items, a due date, and payment instructions.
- Preview the total before exporting a PDF.
- Keep an editable draft if export fails.
TopSecret blacks out anything sensitive in an image or PDF — then exports a flattened copy where the hidden data is genuinely gone, not just hidden behind a rectangle.

A product spec, screen plans, and build steps for your coding agent.

Your first Build Kit is free with a verified email.
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.

TopSecret blacks out anything sensitive in an image or PDF — then exports a flattened copy where the hidden data is genuinely gone, not just hidden behind a rectangle. Most "redaction" just draws a box on top. The text underneath is still there, still selectable, still recoverable. TopSecret rebuilds the pixels: the content under every bar is destroyed, so a redacted name, number, or face can't be selected, copied, or pulled back out of the exported file. REDACT BY HAND OR AUTOMATICALLY • Drag to draw a bar over anything. Move it, resize it, delete it, or undo it. • Auto-Detect finds emails, Social Security numbers, phone numbers, card numbers, IP addresses, and faces. Switch a kind on and every match in the document is blacked out; switch it off to bring them back. • Find & Redact keeps a list of words, numbers, or whole blocks of text — like an address — and blacks out every match, with an optional fuzzy match for close spellings and OCR slips. Remove a term and its matches come back. IMAGES AND MULTI-PAGE PDFS • Import a screenshot, a photo, or a long PDF from Photos or Files. • Step through every page — iPad adds a thumbnail rail alongside it. • Pinch to zoom in, and select text right on the page to copy it, redact it, or redact every copy of it. • Exported PDFs are rasterized, so nothing lingers underneath the bars. PICK UP WHERE YOU LEFT OFF • Save an editable session and come back to it later — your bars, exactly where you left them. • Export a flattened copy any time and share it straight from the app — Files, Mail, Messages, AirDrop, wherever it needs to go. PRIVATE BY DESIGN • Everything happens on your device. All text and face detection uses Apple's on-device Vision framework. • No network, no accounts, no telemetry. TopSecret only ever touches the file you hand it. • One universal app for iPhone and iPad. Redact anything, for good.

Hypothesis 1
Assumption to check: No offline mode
Validate with people who use this workflow before building.

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.
Not assessed in a Build Kit yet.
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.
