Everything you can do
with OnAir
Turn one deck into a video, send it, see how it lands, and sharpen the next version.
Your own voice
Read a short script for about 2 minutes, the way you'd present, and every video sounds like you. Before recording, try it with an AI voice.
An AI script, with sources
AI reads your deck and supporting docs and cites a source for every number. Nothing is made until you approve it.
AI feedback report
Reads your deck the way its audience would — an investor, a judge, a client — and tells you what's missing, which numbers are weak and the questions you'll get. Free, even before you make the video.
Motion graphics
Key numbers count up and comparisons slide in, timed to your voice.
Present in 29 languages
Your recorded voice presents in English, Japanese, Chinese and more — 29 languages. Pick a language on a finished video to make a new version.
Slide animations & captions
PowerPoint and HTML decks keep their own animations; PDF content appears as you talk about it. Captions break at natural phrases, and viewers can turn them on or off.
Send it, see how far they watched
Paste your contacts and send it by email. Recipients watch without logging in, and you see who got to which slide.

Frequently asked questions
Find more answers in the guide.
Do I need to film or edit anything?+
No. All you need is your deck (PDF, PowerPoint or HTML). OnAir handles the script, layout, captions and motion graphics; you just check the script. To use your own voice, record about 2 minutes once.
Is it only for pitch decks?+
No. Pitches are what OnAir does best, but it also works for sales proposals, lectures, reports and company intros. The AI works out what kind of deck it is and writes the script to match.
What if I don't record my voice?+
You can start with an AI voice. Record yours later and re-make the same video in your own voice.
Is my voice safe?+
Your voice is used only to make your own videos. We ask for your consent before cloning it, never share it with other users, and delete it when you ask.
What if a number in the script is wrong?+
The AI only uses numbers found in your materials and cites a source for each one. Nothing is rendered until you've checked, edited and approved the script.
Can I present in other languages?+
Yes. Pick the language when you create a video, and the script, voice, captions and on-screen text follow it. There are 29 to choose from, including English, Korean, Japanese, Chinese and Spanish. Record your voice once and it speaks any of them.
What do people see when I share a link?+
They watch the whole video without logging in or installing anything. You see who watched and how far, and investors who sign up (free) can request a meeting right from the share page.
What does it cost?+
Making videos, sharing links, viewing analytics and AI feedback are free. You pay only when you need the MP4 file or another language version: $19 for one video, or $69 for a Season Pass that covers everything for 90 days. One-time payments, no subscription.
How long does it take?+
A quick preview gives you a 1-minute video about 3 minutes after you upload. With your own settings, the script usually takes 1–2 minutes; a 1-minute video renders in 2–3 minutes, a 10-minute one in about 10. It keeps going even if you close the page.
