KolaVid vs StrokeVideo

KolaVid is a web application that turns prompts and uploaded documents into narrated whiteboard explainer videos. A prompt can describe an idea, lesson, pitch, or training topic; uploaded source material can become a structured visual explanation with scenes and narration. AI scene generation is available, and finished videos can be downloaded. Its presentation style uses white backgrounds, bold labels, visual reveals, simple diagrams, and short labels. Credits are based on finished-video duration, at one credit per second. The free plan provides 120 credits, two video minutes in total, and videos up to two minutes long. Starter costs $14.99 a month and includes 20 video minutes total; Creator costs $39.99 a month with 50 minutes; Studio costs $99.99 a month with 120 minutes. Each paid plan permits videos up to five minutes. KolaVid names teachers, creators, businesses, training teams, founders, NGOs, marketers, and organizations as potential users.

StrokeVideo turns a topic, script, recording, web page or PDF into a narrated whiteboard explainer video downloadable as an MP4. It draws each storyboard board as a complete image, then traces the strokes in time with narration. The service lists 23 drawing styles and narration in 14 languages. Videos can run from 30 seconds to about 15 minutes, while the free daily video is limited to two minutes. Editing means changing the script, storyboard or board timing and rendering again; frame-level edits require another editor and the downloaded MP4. The free plan costs nothing, gives one video daily, no watermark and all styles, with credits expiring that day. Monthly membership costs $19.90 a month; yearly costs $99.90 a year. Free-account videos remain seven days; membership keeps them three months. Commercial use is supported, and the maker names teachers, faceless YouTube channels, marketers and workplace trainers.
