How it works
Upload your deck
Drop in a .pptx, .ppt, or Google Slides export. We preserve slides, animations, and transitions.
Pick a voice for narration
If your slides have speaker notes, AI reads them in your chosen voice. No notes? AI writes narration from the slide content.
Export the video
Render to MP4 with narration, transitions, and captions. Tweak any slide's narration in the editor first if needed.
What it can do
Speaker notes become voiceover
AI reads your existing speaker notes in a natural voice - 30+ voices, 100+ languages. No notes? AI generates narration from the slide content.
Transitions, builds, and motion
Slide transitions, animation effects, and progressive reveals carry over to the video. Your deck looks like itself, only watchable.
Word-level subtitles, styled
Captions sync to the narration word-by-word. Style with your brand or burn them in for muted-autoplay LinkedIn posts.
When the deck needs to play, not be presented
Sales
Async deck walkthroughs
Send a narrated deck instead of scheduling a 30-min meeting. Prospects watch on their time, you free up your calendar.
e.g. Send a narrated proposal deck instead of a call
L&D and trainers
Course videos from existing decks
Turn your training decks into watchable courses without re-shooting. Update slides, regenerate the video - same workflow.
e.g. Convert a 50-slide compliance deck into a video course
Marketing
Webinar replays as videos
Convert your post-webinar deck into an evergreen video for the resource library. Auto-narrated, captioned, ready to embed.
