Design and diagrams decision
Beautiful.ai
A small team can build a usable AI-driven slide generator (outline→slides→export) but reproducing Beautiful.ai’s polished Smart Slides, enterprise security/compliance, collaboration, and analytics at production scale is expensive—keep paying for full-featured team/enterprise needs or build a narrow internal tool.

Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Accept a topic or outline, call an LLM to generate slide-by-slide content, synthesize/generate images, layout each slide into templates, store presentation and assets, and export/share (PDF/PPTX) with basic view tracking.
What it still won’t have
- Polished Smart Slides auto-alignment and animation finesse
- Enterprise security, compliance, and SSO features
- Integrated team workspace, real-time collaboration, and locked brand themes
- Built-in viewer analytics and engagement alerts
- Extensive stock media library and one-click multi-language translation
What remains hard
- Compliance and regulation
Top-tier security: CCPA, PCI, SOC 2 Type II, and GDPR certified

Paying is—cheaper in year one.

Runnable build prompt
Build a minimal AI-driven presentation service: use React for the frontend, Node.js + Express for the API, Postgres for metadata, and S3-compatible object storage for assets. Implement: (1) prompt input and outline editor, (2) server-side LLM calls (OpenAI or similar) to produce slide text, (3) a template-based layout renderer that places text and images into a set of 10 editable Smart Slide templates, (4) optional image generation via an image API, (5) persistence of presentations and assets, (6) export to PDF and PPTX (e.g., Puppeteer + pptxgenjs), and (7) simple share links with basic view-count analytics. Out of scope: real-time multi-user collaboration, enterprise SSO/SCIM, SOC2 compliance, large stock media library, and advanced animations. Include error handling for API failures, input validation, and automated tests covering the generation pipeline and exports.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
