Noren — Demo video

Noren is a Japanese and English map of Nagasaki's local places, with the stories people have already written about them. I went to Nagasaki last month on a nomad program. Every map gave me stars and closing times, so I walked. In an old coffee shop I got talking with a couple from Sydney, and the owner told us her husband made all the art on the walls. Stories like that sit in Japanese reviews and blogs I couldn't find or read. One three-star Google review explains the old stone pillar outside Suwa Shrine: in 1879 the police paid for it so parents could find lost children. Noren collects public posts about a place (Google reviews, blogs, social posts, Reddit) through Apify's free tier and open-source tools, with a script I still run by hand. Many platforms' terms forbid scraping. I did it to find out whether the stories exist, and a real launch would need permission or official routes. Muse Spark reads each post, decides whether the writer said something a rating can't, and copies out their exact words. Code checks those words are in the post. Spark translates each quote, and Muse Glimmer, on my own Modal endpoint, holds back a translation that changes what the writer said. Every night the story agent runs with nobody pressing anything. Spark writes a place's story in English and Japanese from its checked posts, citing the exact words behind every sentence. Code sends back any words it can't find. Glimmer reads each sentence against only the words it cites and lists what they don't support. Spark gets one try to fix it, and whatever still fails is dropped. So far 108 places carry a story. Each story says a model wrote it, and each sentence links to its post. Reviews only catch some of it, so members can write their own story, or paste a link to something they already posted on Instagram, TikTok, Facebook, YouTube, X or a blog. Nobody needs one more app to post on. People already post where their friends, family or readers are, so Noren credits them and sends the readers to them. Most of the map has never been checked by a person, so I borrowed an idea from Waze. A place's page asks whether it's still there. One tap confirms it, puts the place's stamp in your private stamp book, like the ones at Japanese temples, and moves its neighbourhood one place closer to done. The stamp is only the start: what happened to you there can be nothing like what happened to me, and those moments become the story of a place. Anyone can ask for a page to be removed, and a privacy request hides it at once. It's live at noren.yooi.me with 3,612 places from OpenStreetMap and Overture, and about 1,100 checked posts on 359 of them, drawn from about 6,200. It has no real visitors yet: search engines are blocked and sign-up is invite-only. All the product code was written during the hackathon, and the first commit is 30 October 2026. The repository also holds about 110 third-party agent skills and templates.
