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.

Megalith turns a handful of words into a striking, block-justified text graphic — and now sets it in motion. Every line is stretched to fill the same width, with each line's font size set by how much text it holds, so your words form a solid block with clean edges on both sides. It's the look of vintage justified posters ("ON THE BEACH," the old "FALL IN" recruitment prints), rebuilt as a fast, tactile app. Type. Shuffle. Share. Enter a phrase and Megalith lays it out instantly. Don't love the arrangement? Tap Shuffle to re-roll the line breaks and font mix — every tap is a fresh composition. Step back through previous shuffles with Undo. NOW IN MOTION Tap Animate to bring your poster to life. Each line stretches and snaps into place, turning your finished graphic into a short, looping animation. Export it as a GIF or video, built for social posts, stories, and feeds where motion catches the eye. The static poster works exactly as before — Animate just gives it a second life in motion. MADE FOR - Quotes, lyrics, and one-liners - Album-cover and merch-style lettering - Social posts, stories, and covers — still or animated - Anyone who loves bold typography FEATURES - Block-justified layout that fills clean left and right edges automatically - Animate your poster into a looping GIF or video — made for stories and posts - Shuffle to re-roll fonts and line breaks — with Undo - Three typeface families: sans serif, serif, and slab serif - Multiple fonts mixed across lines for real poster character - Force your own line breaks by pressing return - Adjustable minimum line length to control how short a line can get - Pick any text and background color - Use a photo as your background, with optional blur - Four canvas formats: Square, Portrait (4:5), Story (9:16), and Poster (2:3) - Live preview that matches your export exactly — what you see is what you share - High-resolution export to Photos, Messages, social apps, and Files DESIGNED TO FEEL EFFORTLESS Behind the simple interface is a careful layout engine that measures the actual ink of each letter to align edges precisely, then balances fonts and breaks for a result that looks composed, not computed. That same care carries into motion — the animation follows the layout, so it looks designed, not just animated. You just type — Megalith makes it look intentional. No account. No subscription. Just type a few words and make something worth sharing — still or in motion. Screenshots include quotes from Bob Dylan's "From a Buick 6," Carbon Leaf's "Paloma," Saul Williams' "Amethyst Rocks," and Temples' "Keep in the Dark," along with a photo by Gabriele Motter.

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.

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.
