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:
