AI Tools
AI tools. Sorted by what actually ships.
SmolAgents
smolagents is a barebones library for building agents that think in code. It enables running powerful AI agents in a few lines of code, with first-class support for CodeAgents that write actions as Python code snippets. The library is model-agnostic (supports any LLM via Hugging Face, LiteLLM, OpenAI, Anthropic, etc.), tool-agnostic (supports MCP, LangChain, Hub Spaces), and modality-agnostic (text, vision, video, audio). It includes a CLI, sandboxed execution (E2B, Docker, Pyodide), and Hub integration for sharing agents.
ScrapeGraphAI
ScrapeGraphAI is a web scraping API that uses AI to extract structured data from any website without proxies, selectors, or maintenance. It offers endpoints for scraping, extracting, searching, crawling, and monitoring webpages, and integrates with popular AI frameworks like LangChain and LlamaIndex.
AirWeave AI
Airweave is an open-source context retrieval layer that sits between AI systems and data sources, enabling AI agents and RAG pipelines to retrieve relevant context from multiple apps and databases in a single request. It syncs data in real time and exposes it through a unified search interface, supporting semantic, keyword, hybrid, time-aware, and agentic search. With prebuilt connectors for over 50 data sources, it integrates seamlessly with frameworks like LangChain, Composio, and Pipedream.
LangSearch
LangSearch provides a free Web Search API and Semantic Rerank API designed for LLM applications. It supports natural language search, hybrid keyword and vector searches, and uses a transformer-based reranker model for high accuracy. The API delivers clean, high-quality context from billions of web documents including news, images, and videos. It offers easy integration via official API, LLM tools like LangChain, and AI agent plugins.
DeerFlow
DeerFlow is an open-source SuperAgent harness built on LangChain that enables deep research, coding, and content creation. It features an AIO sandbox with browser, shell, file, MCP, and VSCode server, long/short-term memory, planning and sub-tasking, extensible skills and tools, persistent file system, and multi-model support (Doubao, DeepSeek, OpenAI, Gemini). Users can run complex tasks like generating reports, videos, or data analysis autonomously.
Traincore
Trainkore is a unified platform for prompt engineering, model routing, and observability. It enables auto prompt generation, dynamic model switching to optimize cost and performance, and provides an observability suite for debugging and performance analysis. Integrates with OpenAI, Langchain, LlamaIndex, and more.
CatGPT
CatGPT is a GPT-powered search engine that provides reliable answers to cat-related questions along with relevant sources. Created by Arpit Agarwal based on a LangChain example by Lance Martin, it leverages AI to answer queries about cats.
