+.. _vector.aivector:
+
+Artificial intelligence powered vector driver
+=============================================
+
+.. versionadded:: 3.11
+
+.. shortname:: AIVector
+
+.. built_in_by_default::
+
+This driver builds on many years of self-funded investments from the GDAL team on AI
+technologies to bring you the ultimate driver that can read any vector format.
+After that one, no need for any new vector driver!
+
+The open syntax is ``AIVector:{filename}``, or directly specify the filename and
+force the use of the AIVector driver with the ``-if`` flag of ogrinfo or ogr2ogr.
+No options at all. Just enjoy the true power of AI.
+
+.. note:: We are open to external investors to develop the write side of the driver.
+
+Examples
+--------
+
+::
+
+  ogrinfo -if AIVector undocumented_proprietary_format.bin -al
+
+.. note::
+
+    The above works even if you make a typo in the filename. The driver will
+    automatically figure out the filename you meant.
