How Undertone works
Undertone reads along in your own browser and puts what you want to know next to every article, before you read it.
What you see
How an article is likely to make you feel, on one scale from Calm to Frustration. Computed in your browser, from the words of the headline and the text, in Dutch, French, English and German. The author card and the expert sources follow.
Why you can trust it
Because nobody can buy us: no publisher, newsroom or advertiser influences what you see. Because everything happens on your own device: what you read does not leave your browser. And because every fact has a source you can check yourself.
What it does not do
Undertone filters nothing and hides nothing. It is a label, not a gatekeeper.
What is fixed
Your article texts stay with you. What you read never goes to our servers: no full text, no excerpts, nothing from which the text could be reconstructed. We keep only an address or a hash, some numbers, and counts.
The estimate is made in your own browser. That is why Undertone also works behind a paywall, and why we need no newspaper subscription of our own.
Without a source we show nothing. No author background, no estimate and no source without a record of where it came from.
Computed and sourced are never the same thing. An estimate from our model and a cited fact look different everywhere. Other people's numbers are shown as their numbers, with their method; they never enter ours.
Questions about the method? Mail hello@undertone.news.
