Enterprises and developers in need of a solution to connect custom data sources to large language models

About LlamaIndex

LlamaIndex is a “data framework” to help you build LLM apps. Connect semi-structured data from API's like Slack, Salesforce, Notion, etc. LlamaIndex is a simple, flexible data framework for connecting custom data sources to large language models. LlamaIndex provides the key tools to augment your LLM applications with data. Connect your existing data sources and data formats (API's, PDF's, documents, SQL, etc.) to use with a large language model application. Store and index your data for different use cases. Integrate with downstream vector store and database providers. LlamaIndex provides a query interface that accepts any input prompt over your data and returns a knowledge-augmented response. Connect unstructured sources such as documents, raw text files, PDF's, videos, images, etc. Easily integrate structured data sources from Excel, SQL, etc. Provides ways to structure your data (indices, graphs) so that this data can be easily used with LLMs.

Dedoctive

Dedoctive provides auditable AI for defensible decisions. It grounds outputs in trusted evidence, provides full source-level provenance, and governs workflows with human-in-the-loop guardrails. Dedoctive turns complex documents, data, tables and images into verified, source-linked knowledge. It then lets teams build governed AI workflows with human-in-the-loop guardrails where every answer is grounded in validated sources, every step can be inspected, and every statement links back to its evidence. This makes AI outputs usable, checkable, and defensible in settings where generic AI tools are not enough. Dedoctive a neuro-symbolic AI platform combining curated knowledge models, controlled BPMN workflows, full provenance links, Response Maps, multi-format ingestion, custom reports, and formal diagrams. It works with large language models without requiring model training, while giving organisations greater control over what the AI uses, how it reasons, and how outputs are verified.
