The strongest case for Logos AI is not that it uses AI. It is that the product remains useful when the network is bad, the workflow is private, or the user simply wants a calmer study surface.

That is why the product split matters:

• the browser is the on-ramp
• the desktop app is the deeper desk
• offline-friendly workflows create trust instead of dependency

If the free experience is useful before any payment screen appears, people will recommend it. If the desktop app keeps working in the real conditions people actually study in, they come back.

That is a stronger foundation than shipping a flashy demo and then hiding the whole point of the product behind a paywall.
