How privacy works
Privacy that's built in, not just promised.
In memory
Your message is unlocked only for the seconds it takes to answer. Never saved, never logged.
Our database
All we keep is your email, plan, and usage count for billing. No messages, no files. Ever.
One model, as capable as the big-name AIs.
You get a top-tier model on par with the best paid assistants, not a stripped-down version. It thinks problems through instead of guessing, searches the web, reads your files, and understands your images.

Frequently asked questions
Do you store my conversations?
No. Your conversations are never saved on our servers. Your chat history is encrypted on your device, and we only count usage for billing.
Is the free tier actually free?
Yes, and it stays free. Your usage refreshes every 30 days, so you can keep using Nychorium for free as long as you like. Pro is $20 per month whenever you want much higher limits.
How do I pay for Pro?
You can pay by credit card or crypto. Card subscriptions renew monthly and can be cancelled anytime. Crypto payments cover one month of Pro and do not auto-renew.
Is Pro a different model?
No. Free and Pro use the same AI. Pro is about how much you can use it, not a gated better model.
