Can I vibecode SlideFast?
// buildable in a weekend, but real gaps stay open
A personal prompt-to-carousel tool is a solid weekend build, but SlideFast's polished editor, reusable brand system, asset library, dependable multi-format exports, and publishing workflow take sustained product work.

Gioco editoriale: il verdetto dice se un agente può, l’indice se conviene.
What you build
Turn a topic, URL, or rough notes into a structured social carousel, edit the slides, apply a brand theme, and export a LinkedIn-ready PDF.
what you need
- LLM API key
- PDF rendering library
- local image storage
- optional URL content extractor
The core generator is approachable; repeatable visual quality and last-mile publishing are the durable product.
The prompt
A weekend with a coding agent. The gaps that stay are right below, under “what you lose”.
Build me a local AI social-carousel maker to replace SlideFast. Requirements:
- Use Node, Express, SQLite, and a single-page vanilla JS interface.
- A composer accepts a topic, pasted notes, or a URL; URL fetching extracts
readable article text on the server.
- Send the source to one LLM (API key in .env) and require structured JSON:
hook, 5-10 slides, CTA, LinkedIn caption, and hashtags.
- Show every slide in a 1080x1350 canvas preview with inline text editing,
drag-to-reorder, duplicate, delete, and regenerate-one-slide actions.
- Include 4 fixed layouts: cover, statement, bullets, and CTA. Auto-fit text
within strict bounds and warn when copy is too dense.
- Load brand settings from brand.json: logo, two fonts, 4 colors, and footer.
Provide a small settings panel that updates and saves this file.
- Let me upload local images and assign one to a slide; store them under
data/assets and never send them anywhere except the optional LLM call.
- Save projects to SQLite and autosave edits after a short debounce.
- Export every slide as PNG and the full carousel as a LinkedIn-ready PDF
using Playwright, with deterministic dimensions and embedded fonts.
- No accounts, payments, analytics, collaboration, or direct social posting.
- Ship one sample project and a README covering setup, .env, brand.json,
supported input types, and export commands.Curated prompt: written and reviewed by hand for this app. In English on purpose — it is the language coding agents work best in.
What you lose
- polished visual editor
- reusable brand and asset library
- reliable PDF and image exports
- multi-channel publishing workflow
- hosted storage and sharing
Why people still pay
They pay to skip the fragile parts between an AI draft and a consistently branded carousel that is actually ready to publish.
