-Recreate NotebookLM's AI PPT feature and extend it into a controllable, editable, model-configurable PPT workbench that converts papers, documents, and other materials into beautiful PPT images.
+Build a controllable, editable, model-configurable AI PPT workbench inspired by NotebookLM. AIPPT converts papers, documents, and other materials into presentation decks, then exports them as PDF, raster PPTX, or editable PPTX with editable text, native lines/table borders, and separated image assets.

 [Watch the HD demo video](docs/assets/aippt-demo.webm)
 
 The demo covers uploading `doc/L9.md`, entering custom requirements, generating and editing the design outline, confirming page designs, generating a 6-slide deck, editing one slide, confirming the replacement, and exporting PDF/PPTX. Model waiting time is fast-forwarded.
 
+## Latest Update: Editable PPTX Export
+
+Editable PPTX export is now supported. Generated slide images can be reconstructed into PowerPoint-editable pages: OCR text becomes editable text boxes, simple lines and table borders are rebuilt as native shapes, and backgrounds, icons, illustrations, and visual components are separated into movable image assets instead of remaining one full-page bitmap.

 ## More Than A Clone
 
 NotebookLM's PPT feature is closer to a one-click result generator, with limited visibility into the design process and limited per-slide control. This project turns the workflow into an understandable, editable workbench:
 
-- **Visible process**: Review the deck outline and page-by-page design notes before image generation
+- **Visible process**: Review the deck outline and page-by-page design notes before slide generation
 - **Per-slide control**: Edit any slide independently, generate new versions, revert history, and confirm replacements
-- **Model control**: Configure separate OpenAI-compatible models for text planning, image generation, and image editing
+- **Model control**: Configure separate OpenAI-compatible models for text planning, visual understanding, OCR, image generation, and image editing
 - **Local-first config**: Manage model connections through local `config.yaml` or WebUI local API configuration; saved projects and exported files do not include API keys
-- **Export-ready output**: Export generated decks to PDF/PPTX for presentation or further editing
-- **Experimental high-fidelity editable PPTX export**: Rebuild slide images into editable PowerPoint text boxes, conservative native shapes, and positioned bitmap assets through a provider-gated generative editable export path
+- **Export-ready output**: Export generated decks to PDF, raster PPTX, or editable PPTX for presentation and downstream editing
+- **Editable PPTX reconstruction**: Rebuild slide images into editable PowerPoint text boxes, native line/table-border shapes, and positioned bitmap assets through a provider-gated reconstruction path
 
 ## ✨ Features
 
-- 🎨 **Per-slide image generation**: Create an editable outline and page designs before converting them into PPT page images
-- 🌐 **PPT Workbench**: Upload sources, configure model roles, preview slides, edit pages, track history, and export
+- 🎨 **Per-slide generation**: Create an editable outline and page designs before generating polished PPT pages
+- 🌐 **PPT Workbench**: Upload sources, configure model roles, preview slides, edit pages, track history, and export PDF/PPTX
 - 📝 **Multi-format parsing**: Supports `.md/.txt/.pdf/.docx/.pptx` input and converts content to Markdown
 - ✏️ **Full-page image editing**: Edit each generated slide independently, revert history, and confirm replacements
-- 🔀 **Three model roles**: Configure `prompt_model`, `image_model`, and `edit_model` separately
+- 🔀 **Multi-model roles**: Configure `text_model`/`prompt_model`, `vlm_model`, `ocr_model`, `image_model`, and `edit_model` separately as needed
 - 🖼️ **Image result compatibility**: Accepts URLs, Markdown image links, data URLs, `b64_json`, and raw base64
-- 💾 **Local multi-project persistence**: Save multiple PPT projects in the browser, including source content, outline, page designs, generated images, and per-slide edit history
-- 📤 **Editable PPTX reconstruction**: Export a separate experimental high-fidelity editable PPTX mode after provider verification; see [Generative Editable PPTX Export](docs/generative-editable-pptx.md)

-The export menu keeps the existing raster PPTX option and adds a separate experimental high-fidelity editable PPTX option. The editable mode uses OCR plus image editing/image generation providers and is quality-gated by default; it fails rather than silently returning a low-fidelity deck unless an explicit fallback policy is requested. Strict live provider verification is still pending for the currently tested provider set. See [Generative Editable PPTX Export](docs/generative-editable-pptx.md).
