I tried a Tier 1 purchase of Taja last November because I hoped it might help save some time with something I've always had trouble with--crafting good, SEO-optimized descriptions and thumbnails for my videos. I discovered Taja does this admirably (including chapters)! That, in addition to the ability to review/optimize my old videos, suggest new videos, and generate shorts showed me how powerful Taja could be. It's not perfect, some features need some "percolation time" to evolve, but I was pleased enough with the product to go back and purchase additional tiers for unlimited videos--the only AppSumo product I have done this for.
