On-device masking for iPhone and Mac
You decide what AI gets to see.
SendMasked swaps names, ID numbers, addresses and amounts for placeholders before the text leaves your device. Ask ChatGPT, Claude or Gemini as usual — and the answer gets the real details back, on your device.

The principle
SendMasked hides who it is about — not what it is about.
The AI needs to understand the matter to help you: the dispute, the terms, the diagnosis. It does not need to know who it concerns. So identities are masked, not content.
The app
Review exactly what leaves your device.
Every masking is visible in the document. Click one to unmask it, or select text to mask something the app missed.

Documents and attachments
PDF, Word, Excel, email and images open directly — scanned paper too.
Strict by default
Anything that looks like personal data is masked. Unmask what got it wrong with one click.
Same name, same token
Anna, Anna’s and Anna Svensson become [PERSON_1] everywhere, so the answer still makes sense.
The flow
Three steps. No sign-in.
Paste
Text, a document or the clipboard. On Mac also with ⌃⌥M, wherever you are.
Copy the masked text
Paste it into the chat you already use, or send it directly with your own API key.
Paste the answer back
Placeholders turn back into the real details — on your device, not at the AI.
What gets masked
Anything that points to a person or a company.
Checksums for Swedish numbers, patterns for addresses and amounts, and Apple Intelligence for names that are on no list.

Honestly
What the app does — and doesn’t.
Does
- Masks names, numbers, addresses and amounts on your device
- Shows exactly what will be sent before anything leaves the device
- Restores the answer on your device
- Works without an account or our servers — we have none
Doesn’t
- Doesn’t guarantee everything is found — that’s why you always review
- Doesn’t hide what the text is about, on purpose
- Can’t stop role, workplace and dates from sometimes pointing to someone together
- Finds fewer unusual names on older devices without Apple Intelligence
Pricing
Free to start. SEK 99 when you want more.
10 maskings a month. Every feature.
Unlimited maskings. The subscription is handled by Apple and can be cancelled any time.
In direct mode you pay the AI provider separately, with your own key. SendMasked takes none of it.
