Tavily is an AI-native search engine and API built specifically for large language model applications and autonomous AI agents. While traditional search APIs return raw web results designed for human browsing, Tavily returns clean, structured, and fact-verified data that LLMs can directly consume and reason over. This makes it the essential infrastructure layer for any AI application that needs real-time information from the web.

The platform was created to solve a critical problem in AI agent development: LLMs are powerful reasoners but have no real-time access to current information. Tavily bridges this gap by providing a search experience that’s optimized for AI — filtering out spam, extracting key facts, and presenting results in a format that language models can process without hallucination-inducing noise. Whether you’re building a research agent, a customer support bot, or a competitive intelligence system, Tavily gives your AI the information it needs to be accurate and current.

Product Features

• AI-Optimized Search Results: Tavily’s search algorithm is specifically designed to return results that LLMs can consume — clean, factual, and structured rather than raw HTML or SEO-optimized content
• Real-Time Web Access: Query the live web and get current information, not stale training data — essential for any application that needs up-to-date facts, prices, news, or research
• Structured Extraction: Tavily doesn’t just return links — it extracts key facts, summaries, and relevant data from search results, saving your LLM from having to parse raw web pages
• Multi-Query Research: Send a complex research question and Tavily automatically decomposes it into multiple searches, synthesizes the results, and returns a comprehensive answer
• Domain Filtering: Restrict searches to specific domains (e.g., .edu, .gov, arxiv.org) for academic research, or exclude domains for cleaner results
• Python SDK and REST API: Simple integration with both a Python SDK and REST API — get started with just a few lines of code in LangChain, LlamaIndex, or any custom framework

Product Highlights

• Purpose-Built for AI Agents: Unlike general search APIs that were designed for human consumption and retrofitted for AI, Tavily is built from the ground up for LLM and agent workflows
• Anti-Hallucination Architecture: By returning verified, structured facts rather than raw web content, Tavily reduces the risk of LLM hallucination that comes from processing noisy or contradictory search results
• Seamless LangChain Integration: Tavily is an official LangChain tool, making it drop-in compatible with the most popular agent framework — no custom wrappers needed
• Generous Free Tier for Development: The free plan includes 1,000 API calls per month, plenty for prototyping and small-scale applications before scaling up

SciSpace is an AI research companion designed to make scientific literature accessible, understandable, and navigable for researchers at every level. The platform addresses the core challenge of modern research: there are too many papers to read, they’re too complex to quickly understand, and finding the ones that matter for your specific question is increasingly difficult. SciSpace solves this by combining AI-powered paper explanation, intelligent search, citation mapping, and collaborative reading spaces into one integrated platform.

When you open a paper in SciSpace, the AI generates a plain-language explanation of the methodology, key findings, limitations, and implications — translating dense academic prose into understandable summaries. You can ask follow-up questions about specific sections, request clarification of technical terms, or explore how the paper relates to other work in the field. SciSpace’s citation graph shows you which papers this work builds on and which later papers cite it, creating a navigable knowledge map that reveals research lineages and emerging directions.

Product Features

• AI Paper Explanation Engine: Upload or search any paper and SciSpace generates a structured explanation covering research question, methodology, key results, limitations, and significance — in plain language with technical term definitions
