A: This software is completely free and open-source. There are no fees, logins, or subscriptions required. You can use it right out of the box—either by building it from source or by downloading the pre-built Windows release.
A: The software itself imposes no limitations whatsoever. It supports multiple backends, including local models, free APIs, and paid cloud APIs. The first two options (local models and free APIs) are 100% free to use. If you opt for paid APIs (like DeepSeek or Gemini), you will need to top up your balance on their respective platforms, generate an API key, and enter it into the software. Any associated costs are billed directly by the respective providers; this software simply acts as a technical integration tool.
A: Absolutely—where you publish your content is entirely up to you. However, whether the original video content is copyrighted or permits redistribution/repurposing is strictly a matter between you and the copyright holder; the software is not involved in and cannot verify this. Regarding commercial use of local models or third-party APIs, please refer to their respective open-source licenses and Terms of Service.
A: This is a personal open-source passion project—there is no business model or monetization plan. As you can see, we only run a few Google Ads and include sponsorship links on the documentation site to help offset server hosting costs and API token expenses used for testing. Donations are always welcome; your support goes a long way in helping maintain the project over time. Donate
