ChatGPT, Claude, Gemini, Mistral and every other AI, in one app. As your message is sent, your sensitive details are detected and replaced with made-up equivalents, on your computer. The AI works on that version. Your real details take their place back in the answer.
Installs in two minutes. Nothing to set up.
Who it’s for
For everyone who tells an AI things that are none of its business.
Doctors. A report, a prescription, a letter to a colleague or any other document: the AI works on the file without ever knowing who the patient is.Lawyers. Professional secrecy doesn’t stop at the door of a chatbot. Names, cases, amounts and anything else confidential stay in the office.Accountants. Statements, invoices, IBANs, amounts and everything else: the AI works on replaced figures. The real ones come back in the answer, and the totals still add up.Notaries. Parties, property, amounts and every other detail in a deed never leave the office.Sales teams. Clients, prices, terms and everything you negotiate don’t end up at OpenAI or Google.HR teams. Contracts, reviews, pay, letters or any other file: the AI drafts, without ever learning who it’s about.Finance. Credit files, closes, letters or any other file: clients, accounts and amounts are replaced as it is sent. The maths stays right.Companies. Your teams already use AI. Give them every AI in one app, at the level of protection you choose.Individuals. A lease, a letter to the tax office, a health question or anything personal: what concerns you is nobody’s business but yours.

A name becomes another name, a date another date, an IBAN another IBAN, and so on for every sensitive detail. The AI can’t tell the difference and answers as usual. Your real information never leaves your computer: it slips back into the answer the moment it arrives.

Kaviar counts. It keeps nothing.
How many names, dates, numbers, and so on. Never which ones.

Privacy
Everything happens on your computer.
Kaviar is an app installed on your computer, not a service on the internet. Your information never goes through our servers. You keep using the AIs you are used to. They simply stop seeing what’s sensitive.
Ask anything. Reveal nothing.
Two minutes to install. Nothing to set up.
Protection is free. The Pro and Teams plans add AI credits, unlimited documents and team management.
