ChainMemory features
- Cross-model portability. Save memories in one model (e.g., ChatGPT) and recall them in others like Claude or Gemini.
- Cryptographic verification. Each memory gets a hash and project states are anchored with Merkle proofs for immutable integrity.
- Project Brain. Aggregates memories into a structured, queryable project state with decisions, milestones and risks.
- Multi-agent native support. Multiple agents share a single consolidated state with full attribution.
- Chrome extension & MCP server. One-click saving from chat windows or direct integration via MCP for any client.
- REST API & SDKs. Full API and Node.js/Python/Go SDKs to save, search, inject context and verify states programmatically.
LlamaIndex features
- Agentic OCR. Layout-aware parsing of tables, charts, images and handwriting with high accuracy.
- Schema-based Extraction. Turn unstructured content into structured JSON using LLM-powered agents without training.
- Document Splitting & Classification. Automatically segment and categorize documents using natural-language rules.
- Enterprise Indexing. Chunking and embedding pipeline for precise retrieval in RAG applications.
- LiteParse Local Engine. Open-source, fast, on-device parsing of PDFs, Office files and images with no cloud limits.
- Security & Compliance. SOC 2, GDPR, HIPAA compliance with encryption, VPC deployment and granular access controls.
