From Upload to RehearsalIn Four Simple Steps
Transform your presentation for multiple audiences in minutes, not hours
Upload Your Presentation
Start by uploading your PowerPoint file. Our system extracts your slides, text, and existing notes. It takes about 30 seconds to process a typical presentation. You can upload files up to 50MB - usually over 100 slides.
What happens during upload:
- • Slide content extraction and parsing
- • Thumbnail generation for preview
- • Text and image detection
- • Existing notes imported if present
Choose Your Audiences
Select who you're presenting to. We include ready-made personas - Executive, Technical, and Student - or create your own custom personas. Each persona defines the tone, complexity, and focus of your speaker notes.
Default personas included:
- • Executive: High-level, business-focused, concise
- • Technical: Detailed, implementation-focused
- • Student: Educational, accessible, comprehensive
- • Create custom personas with your own parameters
Generate Notes and Audio
We analyze your slides and create speaker notes tailored to each audience using GPT-4. Then, we convert those notes into natural-sounding audio narration. This usually takes 2-3 minutes for a 20-slide presentation. You can regenerate any section you're not happy with.
Generation details:
- • Powered by OpenAI GPT-4 for note generation
- • Choose from ElevenLabs, Play.ht, or Azure voices
- • Average processing: 2-3 minutes for 20 slides
- • Edit notes manually before audio generation
Practice and Present
Use our rehearsal mode to practice with the audio and slides. The slides advance automatically in sync with the narration. You can adjust playback speed, jump to any slide, and track your timing. When you're ready, export everything to use in your actual presentation.
Rehearsal features:
- • Synchronized audio and slide playback
- • Adjustable playback speed (0.5x to 2x)
- • Slide timing analytics
- • Practice on desktop or mobile devices
