Do all surfaces share the same account?
Yes. Sign in with your Lisan account anywhere; your style guides, dictionaries, and statistics follow you.
How do institutions deploy at scale?
Office add-ins and browser extensions deploy centrally via your management tooling, and the engine itself can run on-premises. Your IT team gets a deployment guide during onboarding.
Every word your institution writes, checked.
