Turn your scattered
knowledge into a
verifiable, connected graph.

Aggregate notes, documents, and data from Notion, Obsidian, and more — store them permanently on Filecoin, and explore an auditable, queryable knowledge graph accessible via MCP API or web UI.

Key Features

Everything you need to build a verifiable knowledge infrastructure

Multi-source ingestion

Notion, Obsidian, Git, Drive, RSS

Embedded knowledge graph

Auto-link entities and concepts

Filecoin storage

Verifiable, censorship-resistant, auditable

Cryptographic proofs

Each retrieved passage is verifiable

MCP-compatible API

For AI agents and retrieval pipelines

Visual explorer

Browse your graph, documents, and provenance

Built-in payments

Optional micropayments for premium retrievals

Use Cases

Built for teams and individuals who value data integrity

AI Builders

Plug into your RAG stack for verifiable source retrieval

Researchers

Maintain permanent, linked archives of academic data

Teams

Unify knowledge across silos with provenance

Web3 Projects

Expose project documentation and research verifiably

API, Powered by x402 Protocol

Integrate in minutes. Use our SDK or REST API to query your graph, fetch verified documents, or connect directly to your agent framework.

curl -X POST https://groundline.vercel.app/api/mcp/query \
  -d '{"query": "show research notes about decentralized AI"}'

This query is sent to https://groundline.vercel.app/ and is payment gated using HTTP 402 responses.

Result → JSON with text, metadata, and proofBundle.
