Generate a Presentation from a Document with AI
Upload a document. CFAI reads it, structures it, and generates a lecture-ready presentation outline with TTS playback — running locally on your Windows PC.
From Document to Presentation in Minutes — Without Uploading Your Files
Converting a dense document — a research paper, a technical spec, a meeting report — into a structured presentation is time-consuming. Reading the entire document to understand its structure, deciding what to include, writing slide content, and finding the right level of detail for your audience all take significant effort.
CFAI's Lecture Mode uses Document RAG and AI to generate structured lecture content from any uploaded document. Load your PDF or Word file, prompt CFAI with your target audience and length, and receive a structured outline with section headings, key points, and transition summaries — ready to use as presentation notes or a slide structure.
Because document processing runs locally on your Windows PC, sensitive documents never leave your device. The output can be read back via Piper TTS for offline audio review, exported as structured text, or used directly as a meeting preparation brief. For educators, trainers, and consultants who regularly need to turn documents into presentations, this is a significant time-saving workflow.

How to Generate a Presentation from a Document with CFAI
Upload Your Document
Open CFAI and load your source document: a PDF research paper, Word report, meeting transcript, or any supported file type. CFAI indexes it locally using Document RAG.
Set Your Presentation Parameters
In Lecture Mode, specify: target audience (e.g., executive team, technical audience, students), presentation length (10 minutes, 30 minutes), and focus areas (key findings, methodology, action items).
Generate the Lecture Structure
CFAI uses AI to generate a structured outline: section headings, key points per section, transition summaries, and suggested speaking notes. All derived from your source document.
Review with TTS Playback
Use CFAI's Piper TTS to listen to the AI-generated lecture content. Edit, refine, and export the final structure to your preferred presentation tool.
Frequently Asked Questions
Can AI generate a presentation from a PDF?
Yes. CFAI's Lecture Mode uses Document RAG to read your PDF locally and generate a structured presentation outline with section headings and key points. The document is processed on your Windows PC — no file upload required.
What is Lecture Mode in CFAI?
Lecture Mode uses AI to transform a source document into a structured teaching or presentation format. It generates section outlines, key points, and transition summaries from your uploaded document, and can read the result back via Piper TTS.
Can I generate a presentation from a meeting transcript?
Yes. Upload a meeting transcript to CFAI and use Lecture Mode to extract a structured summary or presentation brief. Useful for turning a discovery call transcript into a client proposal outline, or a workshop transcript into training materials.
Does CFAI upload my documents to generate the presentation?
No. Document processing in CFAI is local — your files are indexed and queried on your Windows PC. If using a cloud LLM backend, only text excerpts (not the full file) are sent for AI generation. With a local LLM (Ollama, LM Studio), the entire process is offline.
