What's New in Koine
1.1
October 10, 2026
One corpus became three. Koine measured you against conversation. Now it also measures you against fiction — 42 public-domain works — and against news. The words that carry a conversation are not the words that carry a news report, and the numbers say so: with 2,000 words known, coverage is 82% of conversation, 72% of fiction, 72% of news. Three corpora also do something a single one could not. The systematic part of your band — the part more questions never narrow — could not be estimated from one corpus at all. With three it can: ±14.7 points, and the step from two corpora to three narrowed it 4.4 times. Reading practice is new. Passages come from the corpora you are measured against, and your progress survives closing the app.
