11 tools

DeepSeek-R1

An autonomous agent designed for deep local and web research, capable of generating detailed reports with citations for various topics.

Perplexica

Open-source AI-powered search engine that performs deep web research to generate and cite answers.

GPT Researcher

An LLM-based autonomous agent that conducts deep local and web research on any topic and generates long reports with citations, with support for connecting to specialized data sources.

DeepSeek-R1

Reasoning-focused open-weight LLM series (and distilled variants) with guidance for local inference; MIT licensed.

RLAMA

RLAMA is a powerful AI-driven document question-answering tool that connects to local Ollama models. It allows users to create, manage, and interact with Retrieval-Augmented Generation (RAG) systems for processing and querying documents via a CLI and API server.

Auto-Deep-Research

An open-source, fully-automated personal AI assistant that serves as a cost-effective alternative to OpenAI's Deep Research. Built on the AutoAgent framework, it supports integration with various LLMs, function-calling interactions, file uploads, and a one-click launch for effortless research automation.

Open Deep Research Agent

An open–source deep research AI agent that utilizes reasoning models to conduct in–depth factual research. It separates planning and research execution for detailed report generation.

GPT-RAG

GPT-RAG is an enterprise-grade Retrieval-Augmented Generation (RAG) solution accelerator designed for integrating Azure Cognitive Search and Azure OpenAI services to power ChatGPT-style and Q&A experiences. It provides a modular architecture featuring data ingestion, an orchestrator (with options for Semantic Kernel functions or AutoGen-driven agentic workflows), and customizable front-end interfaces for efficient deployment in secure, enterprise environments.

DeepSearcher

DeepSearcher is an open-source tool that leverages multiple large language models and vector databases to perform private data search, evaluation, and reasoning, providing accurate answers and comprehensive reports for enterprise knowledge management and intelligent Q&A systems.

Haystack

Haystack is an open-source LLM orchestration framework by deepset-ai that enables developers to build production-ready applications such as retrieval-augmented generation (RAG), question answering systems, semantic search, and conversational agents by connecting various components (models, vector databases, file converters, etc.) into customizable pipelines.

Haystack

Open-source framework for building search, RAG, and LLM pipelines, now with PipelineTool for tool exposure.
