Design and diagrams decision

A single developer can build a useful PDF/DOCX→PPTX generator with LLM summarization and templated PPTX export in about a week, but reproducing the full product (avatars, many bundled image models, enterprise SSO/SCIM, audited security posture, and a team knowledge base) requires more engineering and compliance work.

No open-source build does this yet
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
- Upload a document or paste text → extract and summarize content with an LLM → lay out content into slides → export as PPTX/PDF
What it still won’t have
- Built-in avatar video rendering and voice cloning
- Large catalogue of image models bundled (25+ models)
- Enterprise features: SSO/SCIM, audit logs, SOC2-adjacent hosting, contractual no-model-training guarantees, custom data-residency
- Polished multi-model model-selection UI and team knowledge base with Qdrant search
- 200+ server-side one-off PowerPoint/PDF tools
What remains hard

Runnable build prompt
Build a minimal AI slide-generator web app using: React frontend, FastAPI backend (Python), python-pptx for PPTX export, Tika/pytesseract for PDF text extraction/OCR, OpenAI or similar LLM for summarization (calls metered), and S3-compatible storage. Core features in scope: (1) upload PDF/DOCX and OCR/scaffold text; (2) generate an outline and per-slide text using LLM prompts; (3) render a templated PPTX with titles, bullets, and embedded images; (4) simple review UI to edit slide text before export; (5) authentication via email link (no SSO). Explicitly out of scope: avatar videos, multi-model image-selection UI, SSO/SCIM, enterprise audit logs, HIPAA/BYO encryption. Include error handling for failed OCR/LLM calls, unit tests for extraction and PPTX generation, CI job to run tests, and basic rate-limiting and logging.

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.
