- Choose Limina for a large, multilingual, IT-run deployment; choose Hidden Tokens for teams that want a working workflow this week.

Frequently asked questions
Is Private AI the same company as Limina?
Yes. private-ai.com now redirects to getlimina.ai, and its PrivateGPT product continues under the Limina brand.
Which handles more languages?
Limina states 52 languages. Hidden Tokens detects names, contacts and financial identifiers in any language, but its engine and packs were built first for French and Moroccan documents, and our benchmark shows it still over-codes ordinary English words. If broad multilingual coverage is your main need, Limina is likely the better fit today.
Which is faster to roll out?
Hidden Tokens installs per user on Mac or Windows without administrator rights and starts with a 14-day trial, no account and no card. Limina is deployed by your IT team as containers in your infrastructure.
