Pascal Kienast 0739d3da6a Initial open-source release of Talk AI
Talk AI is a multi-bot AI assistant manager for Nextcloud Talk:
per-bot prompts and models, agentic tool calling (MCP + built-in
tools), RAG over Nextcloud files, room-document search, vision and
speech-to-text attachments, persistent bot wikis, approval workflows,
rate limiting, and multi-provider LLM support (any OpenAI-compatible
endpoint).

Developed within EDUC - the European Digital UniverCity
(https://educalliance.eu), where it runs as the 'EDUC AI' assistant on
the alliance-wide Nextcloud portal. This public repository is the
upstream point of truth; deployment-specific tools plug in via the
tool-provider extension point (docs/TOOL_PROVIDERS.md).
