I bought Castmagic mainly because I have several educational YouTube videos and wanted to repurpose them into written content such as blog articles, LinkedIn posts, or X threads. I chose this tool after confirming it supports multiple languages, since my videos are not in English.

This review reflects my real, early experience after a few days of use.

Documentation (Major Issue)
The first big issue is the lack of proper documentation. There are no clear, detailed guides explaining each feature. I understand that creating full documentation takes time and resources, but for a product aiming to be global, this is extremely important.
They do have a Notion page, but it’s very basic and honestly feels far below what you’d expect from a serious tool.

Transcript Generation (Very Serious Problem)
Unfortunately, I faced a major issue with transcript generation, likely because my videos are not in English.
My videos feature a single speaker, yet the transcript appears as one long block with no proper timestamps or segmentation. Because of this:
- Automatic clip generation does not work
- I’m forced to create clips manually by selecting text
- This completely breaks the workflow
On top of that, I expected the clip feature to automatically generate videos in short-form formats (Shorts/Reels) with proper scaling and framing. Instead, the video is simply placed in the center with captions.
In 2026, with how advanced AI tools have become, this approach feels outdated compared to competing tools.

Performance & Stability
The platform feels somewhat slow, and on multiple occasions when importing a video from YouTube, I encountered errors and had to retry several times until it worked.

Text & Article Generation
For converting videos into written articles, I’d rate it around 70%. The output is decent, but there’s room for improvement.
Since my language is RTL (right-to-left), the editor does not handle it well, which makes reading and editing more difficult than it should be.

Final Thoughts
I’ll continue testing the tool for one more week. If I don’t see noticeable improvements, I’ll most likely request a refund, especially since there are strong competing tools in this space.
