TubeOnAI has great potential for content summarization and repurposing, but if you rely heavily on API integrations to build out your automated workflows, you need to be aware of its current limitations before buying.

Based on my testing, the API currently only supports a very restricted set of inputs:

* YouTube videos
* Articles / Web pages
* PDF / DOCX files
* Rumble videos

Any other media formats—such as podcast audio, local video/audio files, or videos from other social media platforms—are **currently unsupported** via API. If you are planning to build comprehensive, multi-channel automation pipelines, this limitation creates a significant bottleneck. I hope the development team expands the API endpoints soon to unlock this tool's true value for automation builders.
