  1. 1

    We collect

    The new acts of every planning office, as they are published on Diavgeia, around the clock.

  2. 2

    We verify

    From the text of each permit we extract floor area, storeys, uses, pool, engineer and a point on the map. Whatever is not certain stays out.

  3. 3

    We deliver

    On the map, as an alert, in Excel or through the API, the same day. Like this one.

Who we are. The team behind diafaneia.ai, the #1 A.I. platform for public money in Greece. There we read more than 75 million decisions published on Diavgeia, the Greek government transparency portal. With the same technology we read every building permit here, every day.
