Cómo funciona la recuperación.

Cuando generas una lección o una hoja de trabajo, Lessaro incrusta tu objetivo y el contexto de la clase, y luego recupera los pasajes más relevantes de este corpus por similitud semántica. Esos pasajes entran al prompt de generación como conocimiento de dominio, nunca como texto literal. Lo que sale es síntesis propia de Lessaro, calibrada al grado y lista para el aula.

El corpus crece con el tiempo. Cada fuente nueva se evalúa por autoridad, licencia y relevancia pedagógica antes de incorporarla. Si representas a una editorial o a un centro de investigación que quisiera estar incluido, conversemos.
