Upload a PDF and ask it anything. Every user gets their own Neon Postgres project with pgvector, answers stream with an optional view of the model's reasoning, and deleting a document or an account removes it from every system it touched.
How it knows: Deleting an account removes every PDF, the user's own Neon project and every row they own, each step safe to retry, checked end to end against a throwaway tenant until Neon reported the project gone.
