Step 1 of 8
Download your deck from Google Slides
The deck in Google Slides. The speaker notes under each slide become the voiceover.
- In Google Slides, open File ▸ Download ▸ PDF Document (.pdf). This is your slides.
- Wrote speaker notes under your slides? Also download File ▸ Download ▸ Microsoft PowerPoint (.pptx). Knola reads the notes from it in step 4.
- No speaker notes? The PDF is all you need.
Google Slides can play audio, but you have to record a clip for each slide and insert it yourself. Here, the voice reads your words over every slide for you.
Step 2 of 8
Upload your slides PDF
Slides ▸ Upload your own slides (PDF). Knola reads the PDF in a few seconds.
- In Knola, open the course and the lesson the video is for.
- In the Slides section, choose Upload your own slides (PDF) and pick the PDF from Google Slides.
- Each page becomes a slide, up to 80 pages. Uploading slides uses no credits.
Step 3 of 8
No notes? Write what you’ll say
Edit slides: under each slide, What you’ll say holds the words the voice reads.
- Click Edit slides.
- Under each slide, type the words for that slide in What you’ll say. Write it the way you talk.
- Have speaker notes in Google Slides already? Skip this and go to the next step.
Faster than typing: open the dictation on your phone or computer and say what you would say over each slide.
Step 4 of 8
Add your speaker notes
The ⋯ menu under your slides ▸ Add speaker notes from PowerPoint.
- Under your slides, open the ⋯ menu and choose Add speaker notes from PowerPoint.
- Pick the .pptx you downloaded from Google Slides.
- Check each slide next to the note it will get, then click Use these notes.
- Click Edit slides to see each note in What you’ll say. Change any words you like.
The .pptx stays on your computer. Your browser reads the notes from it and only the words go to Knola.
Step 5 of 8
Make a video from your slides
Watch ▸ Make one from your slides.
- Back on the lesson, in the Watch section, click Make one from your slides.
- The whole script shows every slide beside its words. You can still change any of them here.
Step 6 of 8
Choose a voice
Change voice: listen to any of Knola’s six voices for free.
- Click Change voice. Press Listen on any voice to hear it, then Use this voice.
- Have an ElevenLabs account? Connect it and click Show my voices to use a voice you cloned there, even your own.
Knola doesn’t clone voices. You clone your voice in your own ElevenLabs account, then connect it. Videos in your own voice use no Knola credits.
Step 7 of 8
Listen, then make the video
Listen plays one slide in your chosen voice.
- Press Listen under a slide to hear it. Preview plays the whole video. Both are free.
- Click Make the video. You see the cost before you confirm.
- It takes a few minutes. You can leave the page: Knola emails you when it’s ready.
Step 8 of 8
Publish it to your students
The video arrives as a draft: Publish to students when you’re happy.
- Watch it through. Students can’t see it yet.
- Click Publish to students. Or download the video and use it anywhere.

Can you add a voiceover to Google Slides?
Google Slides can play an audio clip on a slide, but you record and insert each clip yourself. To get a voiceover on every slide without recording, download the deck as a PDF and let an AI voice read your words over each slide in Knola. You get more than a voiceover: Knola puts the slides and the voice together into one finished video.
Do my Google Slides speaker notes come with the PDF?
No. A PDF can’t carry speaker notes. Also download the deck as Microsoft PowerPoint (.pptx), then use ⋯ ▸ Add speaker notes from PowerPoint in Knola. The notes go under each slide, word for word.
I have no speaker notes. Can I still do it?
Yes. Upload the PDF, click Edit slides and type what you’ll say under each slide. You can also dictate it.
Can I turn Google Slides into a video and use it outside Knola?
Yes. Download the finished video and use it anywhere, or publish it to a lesson in your course.
Can I use my own voice?
Yes, through ElevenLabs. Knola doesn’t clone voices: you clone yours in your own ElevenLabs account, connect it to Knola, and choose it under Show my voices.
Is the video public as soon as it’s made?
No. It arrives as a draft that only you can see. Publish it to the lesson when you’re happy, or download it and use it anywhere.
What does Knola cost?
Knola is a one-time payment, with no monthly fee. You choose a licence, pay once and keep it. Every licence comes with AI credits for things like narrated videos. See the licences.
