AI voiceover for slides
Add natural AI narration to any presentation. Write your script per slide and Northquill voices and syncs it to your slides — or use your own voice.
AI voiceover for your presentations
Write your narration for each slide, and Northquill voices it in a natural-sounding AI voice, timed automatically to your deck. Prefer your own voice? Upload a recording and Northquill handles the timing.
One natural voice, ready to go
No microphone or recording session needed — just write your script and preview the voiceover before you render.
Write once, render anywhere
Edit any line of the script, adjust the pace, and re-render whenever your deck changes.
How it works
From slides to video in three steps
Upload your deck
Drop in a .pptx, PDF, or Google Slides link. Northquill reads every slide's layout, images, and text.
Add your audio
Upload one recording — Northquill flags filler words and dead air for you to review, then places it across your slides automatically. Prefer typing a script instead? Northquill can generate and time the narration for you, slide by slide.
Render and share
Export a 1080p MP4, or publish a share link. Change a slide later and re-render in a click.
Features
What you get
Any deck goes in
Upload PowerPoint (.pptx), a PDF export, or link a Google Slides file. Your layout, images, and charts come through intact.
Upload once, we clean it up
Upload a single audio file — Northquill flags filler words ("um", "uh") and dead air for you to review, then places it across your slides. No per-slide scripting, no timeline to fight with.
Or generate narration from text
Don't have a recording? Type your script per slide instead and Northquill voices it in a natural AI voice, timed automatically. Entirely optional.
Timed to your slides
Each slide is auto-timed to its narration, with transitions handled for you. Nudge the pacing anywhere it matters.
On brand
Keep your fonts, colors, and logo. Add an intro, outro, and lower-thirds so the video looks like it came from your team.
Export or share
Render to 1080p MP4, or send a share link. Re-render any time the deck changes.
Questions
No. Type your narration for each slide and Northquill voices it in a natural AI voice — or upload your own recording instead if you'd rather use your own voice.
Write your narration in whatever language you want — the AI voice will speak it. There's no automatic translation between languages yet, so you'll need to provide the script in your target language.
