Details

See what the tool accepts, what it checks, how to read the result, and where human review still matters.

Topic	Details	What to know
Input	One bounded PowerPoint package	The public endpoint rejects input outside its documented bound.
Processing	Deterministic rules; no AI model call	The same input and rules produce the same analysis.
Output	Complete analysis or attributed portable output	The free result is returned on the page rather than hidden behind an account.
Storage	Nothing stored	The submitted material is processed for the request only.

What does the paid product add?

Lumen rebuilds the narrative from the current source, chooses the layout for each slide, and generates the visuals for the revised deck.
