Pricing follows a credit model: a free Basic tier capped around 10 minutes of watermarked video a month, a Starter plan at $29 per month that removes the watermark and enables MP4 downloads, and custom Enterprise contracts. Its stated use cases center on corporate training, compliance, and internal communications.
