About Zengist

Zengist turns a pile of documents into one calm brief. It is free, has no account, and runs on your own device whenever your browser can.

Why on-device first

Most free summarizers are a web form in front of someone else's server. Your lease, your lab results, your contract go up the wire, get processed, and sit in a log somewhere. In 2026 that is no longer necessary: desktop Chrome ships a capable model, and every major browser can run a small one over WebGPU. Zengist uses those first. The cloud is a fallback for browsers that cannot, and every result says which path it took.

How it stays free

On-device runs cost nothing to serve, which is most runs. The cloud fallback uses a small model and is capped per person and per day. If Zengist saves you time, you can leave a tip on Ko-fi; tips cover hosting and cloud runs.

What it is not

Zengist is not a lawyer, an accountant or a doctor. It reads what you give it and condenses it; it can miss things and it can misread a scan. Check anything that matters against the original before you act on it.
