Show your video to people who make videos
BolCaps is a free toolbox for captions, voiceovers and short videos. Book a box, upload your own video ad, pick how many days, and your ad plays in front of creators while they work.
Where your ad plays
Three ad boxes, one clear price per day
Video-making screen
A rectangular box beside the progress bar while a creator's video is being made. People wait here for a minute or more, so your ad is seen all the way through.
$8 / day
Free to book
Export screen
Under the Export button, right when a creator's finished video is ready to download or post. High attention, high intent.
$10 / day
Free to book
When a box has no advertiser it shows a Place your ad here invitation, and the homepage keeps its creator video. Longer bookings cost less per day: 7 days or more save 10%, 30 days or more 25%, 90 days or more 35%. Booking two or three boxes together saves another 10%.

Questions
What video should I upload?
An MP4 or WebM up to 20 MB. For the homepage reel use a vertical 9:16 video of about 10 to 30 seconds. For the other two boxes a wide 16:9 video of 10 to 30 seconds looks best. It plays muted on a loop; viewers can turn the sound on.
What are live captions on the homepage reel?
On the homepage box your video is shown inside the BolCaps caption player. Words appear in time with your video and visitors can switch the caption style. You can let BolCaps listen to your video and write the captions for you in your browser, type your own lines, or switch captions off.
How do I pay?
Create your advertiser account, send your request, then press Pay now next to it under My ads. After you pay, press "I have paid" and add your payment reference. We confirm the payment and approve your ad; it starts on the date you chose.
Can I see how my ad did?
Ask us by email and we will send you how many times your ad was shown and how many people clicked your link.
Who else sees my ad?
One advertiser at a time owns each box for the days they booked. Your video is not mixed with other ads in your box.
