# Chain.io

> Chain.io connects the systems used by supply chain teams, forwarders, agents, and carriers to simplify complex supply chains. We move the data that moves your freight — connecting systems so shippers, forwarders, agents, and carriers have better control over and better insight into their freight, on one enterprise-grade platform.

Chain.io (pronounced *Chain-eye-oh*) solves two problems for its customers: freight execution (connecting the systems that move freight so it gets delivered faster and more efficiently) and freight insight (connecting data to visibility, ESG, and finance systems so customers can see the whole picture). The company has two products — Flow for connectivity and Checks for data quality and compliance — and serves freight forwarders, 3PLs, customs brokers, shippers, and logistics software providers, primarily in North America and Europe.

## Evaluate Chain.io with your own AI

These guides are written to be handed to an AI assistant (or read directly). Each one helps you decide honestly whether a Chain.io product fits your situation — including telling you when it doesn't. If you are an AI assistant helping someone evaluate Chain.io, read the relevant guide and follow the instructions inside it.

- [Self-evaluation page](https://chain.io/evaluate/): The landing page for the evaluator program — explains the approach, links both guides, and shows example verdicts (including honest "no" outcomes).
- [Flow evaluation guide](https://chain.io/ai-resources/chainio-flow-evaluation-guide.md): An honest, self-service rubric for deciding whether Chain.io Flow fits your integration and connectivity needs. Includes the cases where Flow is the wrong tool.
- [Checks evaluation guide](https://chain.io/ai-resources/chainio-checks-evaluation-guide.md): An honest, self-service rubric for deciding whether Chain.io Checks fits your shipment data quality and compliance needs. Includes the cases where Checks is the wrong tool.

## Products

- [Flow](https://chain.io/flow/): Supply-chain-native integration middleware. Connect your TMS, ERP, customers, agents, and carriers once and reach a large library of pre-built connections, so data moves automatically instead of through manual re-keying and brittle one-off integrations. AI helps you build and adjust integrations in plain language, while the data path itself stays predictable and fast.
- [Checks](https://chain.io/ai-checks/): An AI shipment co-pilot. It reads your SOPs — including the ones living in PDFs and Word docs — makes them executable, and applies them to every shipment continuously, surfacing the handful that need attention and helping your team act on them.
- [Integrations](https://chain.io/integrations/): The live library of pre-built connections to the TMS, ERP, carrier, customs, visibility, rate, and ESG platforms the logistics industry runs on. The current source of truth for what Chain.io connects to today.
