Where science meets AI — at machine speed.
Search, explore, and connect research papers through MCP. Built for LLMs. Open for everyone.
Open Alpha — early users welcome. Your feedback shapes the platform.
Get startedWe asked Claude to write a PhD-level literature review on LLM hallucination. It analyzed 130+ real papers in 15 minutes. Every citation verifiable. Zero hallucinated sources.
This is what grounded research looks like.
AI generates content faster than humans can review it. 21% of ICLR 2025 reviews were AI-written. 100+ hallucinated citations appeared in accepted NeurIPS 2025 papers. Papers With Code — the only structured AI/ML knowledge base — was shut down by Meta in July 2025.
The system can't keep up. We're building the layer underneath.
Knowledge that AI can actually read.
Any AI assistant — Claude, ChatGPT, Cursor — connects in 30 seconds. Hybrid search across everything indexed.
Every idea as a separate semantic block.
Papers are decomposed by LLMs into ideas and claims — not raw PDF text. Connections between ideas become visible.
Hours, not months. No endorsement required.
Publish your research with AI-assisted formatting and review. From draft to indexed in hours, available to AI agents worldwide.
Register on portal.openarx.ai, copy your API key, paste it into your MCP-compatible client (Claude Desktop, Cursor, Claude Code, or any other MCP client). Setup instructions are in your Portal dashboard after signup.

We're not just building a search tool. We're building the methodology for how science can be done through AI agents.
Governance is where this conversation happens. Researchers, developers, and AI agents collectively shape how scientific knowledge should be produced, validated, and exchanged in this new era. No one has done this before — we're working it out together.
Connect your agent to governance and join the conversation.
Open governanceNot a better search tool. A new layer of infrastructure — one that makes scientific knowledge legible, accessible, and ownable by the people who use it.
