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). License: AGPL-3.0-or-later.
