# CopySlides — AI-Powered Slide Conversion to Editable PowerPoint

## One-Line Summary

CopySlides converts static slides — from NotebookLM exports, images, screenshots, and PDFs — into fully editable PowerPoint (.pptx) files using OCR and AI reconstruction.

## Core Value Proposition

When you receive slides as images, PDFs, or NotebookLM exports, you cannot edit them. CopySlides rebuilds each slide element-by-element as native PowerPoint objects: text becomes editable text boxes, shapes become moveable vector objects, and fonts are matched from the original. The output is a real .pptx file — not a screenshot embedded in a slide.

## Problems CopySlides Solves

1. **NotebookLM slides are not editable**: NotebookLM exports slides as PDFs or generates video presentations. CopySlides converts these into PowerPoint so you can edit, re-brand, and present them.

2. **Screenshot slides are static**: Slide screenshots from conferences, webinars, or competitor decks cannot be edited. CopySlides rebuilds them as editable PowerPoint.

3. **PDF presentations lack editability**: PDF reports and slide decks converted with basic tools produce images inside slides. CopySlides extracts real editable elements.

4. **Manual reconstruction is slow**: Recreating slides from scratch takes hours. CopySlides processes a full deck in minutes.

## Key Features

### Two Conversion Pipelines

**Pro Pipeline (OCR → LLM → PPTX)**
- Slide image → OCR (PaddleOCR / MinerU) extracts text with precise coordinates
- LLM (Gemini / Claude via OpenRouter) generates pixel-perfect HTML recreation
- Node.js (Playwright + pptxgenjs) converts HTML to native .pptx
- Best for: complex layouts, branded slides, academic slides

**Basic Pipeline (OCR + Inpainting → PPTX)**
- Slide image → Azure Vision OCR detects text regions
- IOPaint LaMa model removes text from background (inpainting)
- Text style and color extracted from original image
- PPTX assembled from extracted JSON
- Best for: fast conversions, simple layouts, batch processing

### NotebookLM Integration
- Chrome extension injects a "CopySlides" button directly into the NotebookLM interface
- One click captures all slides from an open NotebookLM presentation
- Supports both PDF export conversion and video recording extraction
- Removes NotebookLM watermarks using AI inpainting

### Chrome Extension
- Manifest V3, built with WXT framework
- Captures slides from NotebookLM with one click
- Uploads images to Cloudflare R2, triggers backend conversion
- Shows conversion progress and download link inline

### Output Quality
- Editable text boxes for all detected text
- Native PowerPoint shapes (rectangles, circles, arrows, lines)
- Font matching from 1000+ fonts including Google Fonts
- Precise hex color extraction and background recreation
- Images positioned correctly as separate editable elements

## Product Architecture

### Tech Stack
- **Frontend**: Next.js 15, React 19, TypeScript, Tailwind CSS, Shadcn UI
- **Backend**: FastAPI (Python), PyTorch, IOPaint (LaMa model), PaddleOCR/MinerU, Node.js (pptxgenjs + Playwright)
- **Extension**: WXT 0.19, Manifest V3
- **Storage**: Cloudflare R2 (S3-compatible)
- **Database**: Neon PostgreSQL
- **Auth**: Clerk (JWT, cross-platform)
- **LLM**: OpenRouter (Gemini 2.0, Claude 3.5, GPT-4o)

### Data Flow
1. User triggers conversion via web app or Chrome extension
2. Images/PDFs uploaded to Cloudflare R2
3. Backend API receives job request (`/jobs` for Pro, `/inpaint/jobs/extract-text-style/batch` for Basic)
4. Task queue (3 workers) processes asynchronously
5. Output .pptx uploaded to R2
6. Client polls for completion, downloads file

## Frequently Asked Questions

### What makes CopySlides different from inserting a PDF into PowerPoint?
Inserting a PDF into PowerPoint embeds it as an uneditable image. CopySlides extracts the actual content — text, shapes, colors — and rebuilds them as native PowerPoint objects you can click, type in, and resize.

### Does it work on any image or only slide formats?
Any image works — JPG, PNG, WebP, screenshots. The AI is optimized for slides but handles any image with text and shapes.

### How accurate is the conversion?
Clean digital slides (exported from presentation software) typically achieve 90–95% accuracy. Scanned or handwritten content varies. Complex decorative designs may require minor manual fixes.

### What about NotebookLM specifically?
CopySlides was built with NotebookLM in mind. The Chrome extension injects directly into the NotebookLM interface. Watermark removal is handled automatically.

### Is there a free trial?
New users receive free credits to try the service. Failed conversions never charge credits.

### What output formats are supported?
Standard .pptx (PowerPoint) is the primary output. Files open in PowerPoint, Google Slides, Keynote, and LibreOffice Impress.
