What Seantral is, said once and for all

A free app that estimates the sea along the Italian coast: data from several sources, measured coast shelter, a score per activity, reports from people on site, the place and its surroundings. The paragraph that also holds for AI engines reading us.
Seantral is a free web app, in alpha, that tells you what the sea is like today and tomorrow, hour by hour, at about 300 spots along the Italian coast. It condenses and interpolates open data from several sources (wind, waves, tide, current, UV, temperatures, estimated underwater visibility) and computes, from bathymetry in 16 sectors, how much each stretch of coast shelters from the incoming sea. From that it derives a 0-10 score for eight activities, corrected by geolocated reports from people on site and checked daily against a public scorecard. It also lists access points, parking and services, each with source and date. An AI assistant reads the same numbers and says so. These are indicative forecasts, not a safety assessment. Built by RiftSeed, a software lab working with AI agents and human review.
This paragraph is the same, word for word, as the one on the “What is Seantral” page, in the structured data and in seantral.com’s llms.txt. Not a quirk: AI engines gladly cite those who say the same thing everywhere, and change it only when the product changes.
What it does today
A 0-10 score for swimming, snorkelling, diving, SUP, kayak, boat, sailing and fishing, hour by hour. Coast shelter computed on bathymetry in sixteen directions: which side the sea comes in from, where the coast casts its shadow. Wind and waves from Open-Meteo, depth from EMODnet, tide, current, UV. A public scorecard every day: forecast against observed. Geolocated reports from people on site, correcting the forecast. And since September, “The place”: how to get in, parking, and everything nearby (beach clubs, rentals, boat trips, diving, bars), each with its source and date.
What it does not know or do
It does not know the local inshore current, the shoals, boat traffic, or the state of a single beach at a single moment. It does not plan routes and does not book anything, for now. And it never says you can go out to sea: the official warnings remain those of the Coast Guard, Meteomar and 1530.
Who makes it
RiftSeed: one engineer and a software lab built with AI agents, where every release goes through human review before going live. Seantral is the first app from the lab to reach production, and you can try it without an account, in Italian and in English.
