The project began three years ago, and the code was released last month under the AGPL-3.0 license. The organization explained that while the content is currently under copyright, it is planned to transition to a CC-BY 4.0 license within the next 6 to 12 months.
Regarding privacy, the system is configured to allow self-hosting on Hetzner GPU servers. It employs Qwen3-TTS and Kokoro TTS for voice generation, and Faster-Whisper for transcription. The organization stated that the service is hosted within the EU, is GDPR compliant, requires no registration, and does not use tracking cookies.
Users can utilize 30 free messages daily. BYOK (Bring Your Own Key) and full local self-hosting modes are also provided. The development team stated that their mission is for this application to serve as an "entry point" leading users toward primary sources and human teachers.
