AI needs context. Not identity.

Ainym works right inside the AI chat you already use. It spots personal data before you send, swaps it for realistic stand-ins on your device and puts the real details back into the answer. Your team gets the full power of AI. The real names stay with you.

The problem

Ban it, allow it
or build it?

Your team already works with AI. The real question is what gets sent along with it. The usual answers all come at a price. There is a better one.

A

Ban it

Your team loses a tool it relies on every day, and the time it saved is gone again.

B

Just allow it

Names, account numbers and entire files reach the AI provider in plain text.

C

Run your own model

A major project in its own right, with its own budget and a team to keep it running.

D

Ainym

Your team keeps the AI it loves. Ainym takes the identity out before anything is sent.

How it works

Four steps,
one flow.

01

Dear Ms Weber, on behalf of Michael Lehmann please transfer the amount to IBAN DE44 5001 0517…

Detect

While you type or attach a file, Ainym checks the content right on your device. Checksum rules catch IBANs, tax IDs and card numbers. A language model in your browser picks up names, addresses and companies.

Review

Before anything is sent, you see every match in context, already ticked. Untick what isn't personal, add anything you want covered, then approve. Nothing goes out without your go-ahead.

Replace

Real details become believable stand-ins, not black bars. Ms stays Ms and a letter still reads like a letter, so the AI can work at full strength.

Format in.
Format out.

What you upload is what you get back. Fonts, tables, headers and page breaks stay exactly where they were.

The AI can even work inside the document. Have it rewrite a clause or add a paragraph, and the file still comes back in your formatting, with the real names in place.

Questions

Straight
answers.

Does the AI provider see my original text?

The AI provider only receives the version you approved, with stand-ins in place of the real details. Your originals and the mapping stay on your device.

Is that anonymisation?

It is pseudonymisation, and it happens before anything leaves your device. The AI works with stand-ins and never needs the real names. Legally, pseudonymised data remains personal data, so your own assessment still applies. The difference is how much less you disclose.

What if Ainym marks something that isn't personal?

One click and the mark is gone. You see every match in context before sending, and nothing in your text changes without you seeing it.

And what if it misses something?

You always have the last word. Checksum rules and a language model on your device do the searching, and you see the result before anything is sent. No detector catches everything, so anything else you spot can be added with a click before you approve.

Can we get started now?

Yes, as a pilot team. Ainym is in closed beta: we personally onboard a small number of teams, agree the scope with you and stay in direct contact while we keep building.
