Technology

Multi-model orchestration

Rather than handing every task to a single model, we connect AI engines suited to each role: chat, images, speech recognition and speech synthesis. In the chatbot, users pick the model themselves; in each tool, a designated engine runs with prompts designed for that purpose.

Response streaming, authentication and per-feature AI usage logging are managed together on CoreSynaptics servers.

The school record tools for topic suggestions and remark writing run on Claude Sonnet 5. AI Note Q&A and automatic comic storyboards currently use Google Gemini.

Each AI engine is accessed through its provider’s API; this does not imply an official partnership or certification. Model lineup as of October 2026 and subject to change as the service evolves.
