Your lecture recording + your slides = one polished teaching video
Record yourself teaching. Add your slide deck. LectureFuse builds a broadcast-quality presenter-and-slides video — with slides that advance automatically, in sync with what you say.

Avatar generators replace you with a synthetic presenter. LectureFuse polishes the real you — your voice, your delivery, your slides.
AI-synced slides
The AI reads your transcript and your slides, then places each slide change at the exact moment you start talking about it. Drag any change point to fine-tune.
Private by design
The video is processed entirely on your own PC. Only the transcript text and small slide thumbnails are sent for AI sync — never the recording itself.
Branded automatically
The video chrome — colors, frames, labels — is sampled from your deck's own palette, so every video matches your course branding without design work.
How it works
Pick two files. Your talking-head recording (any webcam or phone video) and your slide deck (PDF — export from PowerPoint, Keynote or Google Slides).
LectureFuse does the rest. It transcribes your speech word-by-word, renders your slides, matches each slide to the moment you discuss it, and composes the video: full-screen title, presenter opener, side-by-side teaching section, and outro.
Review and render. Adjust any slide timing on the visual timeline, hit render, and upload the finished MP4 to your LMS, YouTube, or MOOC platform.
