Knowlify's limits are the usual reason to shop around. Free videos are watermarked and stop at 30 seconds, Pro stops at 2 minutes and Max at 10, so longer courses must be split. Usage is metered in credits, Studio has no public price, and the privacy page returned a 404, leaving data handling unverified.
Synthesia makes presenter videos with AI avatars and voiceovers in 160+ languages; its Starter plan is $29 per month billed monthly, the same figure as Knowlify Pro, and it has a free plan. Runway is a broader creative tool for generating and editing video, images and audio with an API, and its Standard plan is $15 per month per user, also with a free option. Synthesia suits talking-head training; Runway suits freeform footage.
