Lyzr Blocks
Lyzr Blocks are standalone AI capabilities — available as independent API endpoints you can add to any application or agent framework. You don’t need Agent Studio or a full Lyzr agent to use them.Available blocks
Knowledge Base
RAG-as-a-service. Create a knowledge base, upload documents, and query it from any application — LangChain agents, Semantic Kernel, custom code. The same Knowledge Base you build in Agent Studio is accessible as a standalone service. One KB, used by any agent from any framework.Cognis (Memory)
Memory-as-a-service. Lyzr’s production-grade memory module available via API and MCP. Plug Cognis into any agent for cross-session, temporal-aware memory without building a memory system yourself. Available integrations: Cursor, Claude Desktop, Zed, Opencode, and any custom agent via the Cognis MCP server or REST API.Responsible AI
Guardrails-as-a-service. Apply toxicity detection, PII redaction, prompt injection protection, and content filtering to any pipeline — not just Lyzr agents.Voice Agents
Voice infrastructure for building conversational phone experiences. Includes telephony integrations (Twilio, Telnyx, Plivo), real-time transcription, and analytics — usable independently of Agent Studio.When to use Blocks vs. Agent Studio
Use Blocks when:- You have existing infrastructure (LangChain, custom) and want to add one specific capability
- You want your KB or memory layer to be independent of the agent framework
- You’re integrating into a non-Lyzr stack (e.g., a CrewAI or LangGraph pipeline)
- You want the full agent experience: visual building, monitoring, eval, and governance
- You’re building new agents from scratch rather than adding to an existing system
