## Context

**Beautiful.ai** — Presentation builder with smart templates and auto-formatting. It currently costs $45/mo.

You can build a template deck generator, but auto-layout slide behavior, template polish, brand controls, PowerPoint import/export, and collaboration are real work.

This brief describes a focused, single-operator replacement for the part of Beautiful.ai that is genuinely reproducible. It is deliberately narrower than the product it replaces, and it says so in writing. Build the useful core; do not pretend to have rebuilt the rest.

## What you are building

Generate slides from structured content, apply smart templates, auto-fit text/images, export to PDF/PPTX.

- Build a focused single-user workflow with real persistence, search, and export.
- A responsive interface with real empty, loading, success, and error states.

## Requirements

### Functional

- Slide layout engine.
- PPTX/PDF export library.
- Template library.
- Hosted app.

### Data and integrations

- LLM API.

Each of these needs a real account, credential, or quota. Set them up before writing feature code.

### Non-functional

- Accessibility: semantic markup, labelled controls, visible focus, and reduced-motion support.
- Security: server-side secrets, validated input, and no credentials in the client bundle.
- Reliability: retries with backoff on external calls, and a clear failure state when a provider is down.
- Portability: the operator can export their data and leave without losing it.

## Implementation brief

Build me a Markdown slide deck tool to replace Beautiful.ai. Requirements:

- A CLI plus local preview: Node, decks are Markdown files rendered with
  reveal.js. deck serve talk.md gives a live-reload preview on localhost;
  deck export talk.md prints a PDF with Playwright.
- Slide syntax: --- starts a new slide, Note: lines become speaker notes.
- 4 layouts picked by a comment on the slide's first line: title, bullets,
  big-number, and image+text two-column. Layouts are plain CSS files I can
  edit.
- Auto-fit instead of clipping: when a slide overflows, step the text size
  down once and print a terminal warning naming the tight slides.
- theme.json for brand: two fonts, 4 colors, and a logo in the corner of
  every slide.
- Optional: deck draft "topic" < notes.txt sends my rough notes to an LLM
  (Anthropic or OpenAI key in .env) and writes a starter deck for me to
  edit; the LLM is never involved in rendering.
- Decks are plain files in a folder, fully local, no accounts, no telemetry.
- Out of scope: PPTX export and collaboration; the HTML deck plus PDF is
  enough. Do not chase Beautiful.ai's self-designing layouts, that engine is
  the product.
- README: setup and the whole slide syntax in ten lines.

## Delivery standard

- Inspect the repository first, then write a short implementation plan before writing code.
- Deliver the smallest complete end-to-end workflow first; every primary control must work against persisted data.
- Use real validation and storage; never substitute fake dashboards, decorative controls, hard-coded success states, or mock integrations.
- Include responsive layouts plus genuine empty, loading, success, validation, and failure states.
- Keep secrets server-side in environment variables, provide .env.example, and never commit credentials or user data.
- Add structured logs around every external call and return actionable errors without leaking sensitive details.
- Write unit tests for the core logic and one automated test of the main user journey.
- Finish with a README covering setup, architecture, data location, backups, tests, deployment, and known limitations.

## Acceptance criteria

- [ ] A clean install starts the app using only the README and .env.example.
- [ ] The primary journey works from first visit through saved result, reload, edit, export, and deletion where applicable.
- [ ] Invalid input, missing configuration, provider failure, and an empty database each have a usable state.
- [ ] The interface works at 390px and 1440px, is keyboard navigable, and shows visible focus on every control.
- [ ] Tests, type checking, linting, and a production build all pass with no ignored failures.
- [ ] No part of the interface implies a live integration, security guarantee, or scale capability that was not actually built and verified.

## Non-goals

Do not build these, and do not claim to have replaced them:

- Smart templates.
- Brand controls.
- Shared libraries.
- PowerPoint compatibility.
- The last 20 percent is sync, migration fidelity, speed, and edge cases.
- Licensed content and distribution rights are not reproducible with an LLM.

## What you still own after launch

- Secure credentials, rotate secrets, and handle provider rate limits.
- Run migrations, backups, restores, and dependency updates.
- Test the critical journey after every model, API, or hosting change.
- Monitor failures and fix the edge cases a first prompt will miss.

## Risk

**Manageable.** A personal version is realistic if you test the critical journey and keep reliable backups.

Editorial confidence in this assessment: medium. No independent one-shot implementation is linked yet.

## Prior art

Working open-source software you can read, fork, or borrow from before starting:

- [reveal.js](https://github.com/hakimel/reveal.js) — Open-source HTML presentation framework; useful rendering layer but not the smart-template
