Turn PowerPoint into a lecture video — no mic, no re-takes
Stop re-recording lectures at midnight. Drop in your slides and AI writes the narration script, voices it in a natural voice, and syncs subtitles and animations — a finished lecture video in the time it takes to make coffee.
We've all pulled those recording all-nighters
One flub, start over
Recording yourself means every slip costs a whole take. A 10-minute lecture can eat an entire evening.
Post-production is the real course
Cutting filler words, timing subtitles, tweaking the timeline — the edit takes longer than the class.
Slides change, video dies
Update the deck and the old recording is obsolete, so you re-record everything. Again.
From deck to lesson in three steps
- 1
Drop in your slides
.pptx / .pdf supported — layouts and images stay exactly as you designed them.
- 2
AI scripts and voices it
A per-page narration script, natural AI voices, subtitles and scene animations synced automatically.
- 3
Export the lesson
Rendered on your own machine, up to 4K — ready for your LMS, course platform or class group.
Built for people who teach
Editable per-page script
Tweak any page's wording, regenerate just that page's voiceover — never the whole take.
Natural AI voices
No flubs, no filler words. Voices that sound like a teacher, not a terminal.
Subtitles & animations in sync
Highlights, zooms and spotlights follow the narration, so students watch the right spot.
Two-host interview mode
Turn key points into a Q&A conversation that holds attention better than a monologue.
Updates stay local
Change one slide, redo one page — not the whole evening.
Field guides for this workflow
Screen-recording a PPT? Decide what you're recording first
Screen recorders capture pixels, not explanations. Four ways to narrate a deck — live voice-over while recording, voice-over after, on-camera presenter, or AI script and voice — compared on flubs, rework, gear and data safety.
6 min readHow to add subtitles to a lecture video automatically
Timing subtitles by hand is the slowest part of a microlecture. Editor auto-captions, screen recording plus post, and subtitles generated straight from the narration script — compared on accuracy, rework and fit.
6 min readWhat gear do you actually need to record a lecture?
Real budgets and priorities for audio, camera, lighting and editing, the three things sales pages won't tell you, the classes that genuinely need filming — and the zero-gear route that doesn't.
6 min readHow to turn a PPT into a lecture video — no script, no mic, no re-takes
Work out where the hours actually go before choosing a route. A full path from an existing deck to a narrated lecture video, with a time table, script advice, export settings and three hard limits.

What educators ask most
I keep stumbling when recording lectures. What now?
Don't record. SlideTalk writes a per-page narration script you can edit line by line, then an AI voice delivers it — no flubs, no re-takes. Change one sentence, regenerate one page.
Can I use the videos in competitions or on my course platform?
Yes. Videos render locally on your machine, up to 4K, and the content is entirely yours — use it anywhere. Any first top-up permanently removes the export watermark.
My slides changed. Do I have to redo the whole video?
No. Re-import the updated deck and only regenerate the pages that changed — scripts and voiceovers are produced page by page.
I'm on a Mac. What about Windows?
SlideTalk is Apple-native: one universal app for Mac (macOS 15.1+), iPhone and iPad (iOS/iPadOS 17+), on the App Store. There is no Windows version.
Is it free?
Download, import, editing, voice previews, rendering and export (including 4K) are free forever. Only AI generation is metered: 1 credit/page for scripts, 1 credit/10 characters for voiceover. You get 600 welcome credits — about 1.7 ten-page videos — to try it first.
