Licensing & Compatibility

• License: AGPL-3.0.
• Compatibility: The AGPL-3.0 license is a strong copyleft license. Its use may impose obligations on derivative works and software linked with it, potentially requiring source code disclosure for modifications or linked components, which could affect compatibility with closed-source commercial applications.

Limitations & Caveats

The AGPL-3.0 license may present adoption challenges for closed-source commercial products due to its copyleft provisions. While data processing is local, access to many advanced AI models relies on external API providers like OpenRouter, requiring an internet connection and potential costs. Official installers are provided for Windows and macOS; Linux support is not explicitly detailed.
