About 毎日ミステリー
[One Mystery Story Every Day: From Full-Scale Mysteries to Everyday Mysteries]
Daily Mystery is a short story delivery app where AI writes a new mystery novel every day, and you can enjoy a quiz to guess the culprit after reading. From full-scale crimes to "everyday mysteries" lurking in schools and shopping districts, we deliver stories with different settings and different styles every day.
On your commute. During breaks at work. In the moments before you go to sleep.
Each story is a short story that can be read in about 5 minutes, and a new mystery awaits you every day.
■ Guaranteed "Logical Inconsistencies" in Both Full-Scale and Everyday Mysteries
At the core of Daily Mystery is a unique three-stage generation engine.
First, the framework of the case is assembled as structural data, and another AI rigorously verifies whether "the truth can be reached using only the clues presented to the reader," and only stories that pass this test are written into prose.
We deliver stories that adhere to the conventions of mystery novels, thoroughly eliminating "fair play violations" such as pointing out the culprit with evidence revealed after the fact. ■ Test your deductive skills with a post-reading culprit quiz
At the end of the story, there's a multiple-choice quiz where you select the culprit from a list of suspects.
Successfully solving the mystery brings a sense of accomplishment, while incorrect answers allow you to review the "decisive clue" in the explanation.
You can review your consecutive correct answer days, total number of stories read, and correct answer rate in the "Records" tab.
■ More than just solving, a story that lingers after reading
Beyond the enjoyment of solving the mystery.
The detective is Rina, a high school girl with keen observational skills. Every day, she encounters a different case, and together they solve the mystery.
This isn't a dry whodunit; it's a mystery as a "story" that leaves a lasting impression after you finish reading.
■ Diverse settings and styles
From full-fledged mysteries to everyday puzzles and cozy mysteries, the AI weaves stories in a variety of situations.
A locked room in a Western-style mansion, a lighthouse on a remote island, a school classroom, a bakery in a shopping district... a different setting, a different case every day.
