Níyì: Look at your data without sending it anywhereNíyì

A free tool that turns spreadsheets into charts and plain-language reports, built to work offline on old computers. Made for peacebuilders, NGOs and journalists working with sensitive data.

ABOUT THE TOOL

Your data stays on your device

Níyì helps you look at your data without sending it anywhere. You download one small file, turn your internet off, and it works the same.

It is not AI and makes no network calls. It is deliberately small so it runs on older machines. Built by the PeaceTech Alliance, and free to use.

Níyì: a 90-second walkthrough

With captions. Everything shown uses made-up data.

WHY WE BUILT IT

Built to fit a need, with no funding and no masters

Many of the open answers in the PeaceTech in Practice dataset expressed the need for offline tools. Níyì is a response to that, and it was the original idea behind it.

Níyì was launched at The PeaceTech We Want Summit on 19 October 2026, hosted by the Open Knowledge Foundation and the PeaceTech Alliance.

Níyì was built by the PeaceTech Alliance, and it is completely free to use. No funding has gone into it, and there are no masters behind it. It was made to create something that can help, and you will never be asked for money to use it.

Why It Exists

Field practitioners often need to check or visualise data, such as incident logs, survey exports or monitoring data. The usual routes both carry a cost: sending data to a major AI model means uploading it somewhere you may not trust, and traditional data science needs expertise most teams don't have on hand.

Where the internet is monitored. Some people work in places where online activity is watched, but still need to look at their data. Níyì lets you check and visualise it without anything leaving your device.

Where there is no internet. Some people work in areas with no connection, yet still do their analysis and admin on their machines. Níyì works there too, including on older computers.

If you handle data from vulnerable groups, uploading it to a big AI tool can put you and the people you work with at risk. Níyì is here so you do not have to.

In Practitioners' Words

Many open answers in the PeaceTech in Practice dataset expressed the need for offline tools. Níyì is a response to that.

"Internet access is a huge barrier in remote areas. We need tools that work offline or with very low bandwidth."

Project Manager, East Africa

"Many of our beneficiaries have no internet or very limited data. Offline functionality is critical for inclusion."

Program Coordinator, West Africa

From PeaceTech in Practice, a survey of 211 practitioners (Holzinger & Coyle, 2026, 10.7910/DVN/7VAN5E).
