Coverword swaps names, emails, phone numbers, account numbers and other private details for placeholders before your message reaches the AI. You still see the real values. The AI never does.

Works right inside the AI assistants your team already uses
Your team already pastes client emails, patient notes and case files into AI to get work done faster. Once it is sent, it sits on someone else's servers. Coverword makes sure the private parts never go.
No new app, no copy-and-paste ritual. Install it once and it runs quietly inside the AI sites you already use.
Write your prompt in ChatGPT, Claude or Gemini, client details and all.
Private details become placeholders the moment you paste or press Send. The same value always gets the same placeholder, so the AI can still follow who is who.
Hover any placeholder in the answer to see the real value. Copy the answer and the real names come back with it, ready to send.
Pick the mode that fits how careful your office needs to be. You can switch any time from the toolbar.

A privacy tool that uploads your text to check it would defeat the point. Coverword does all of its work on your computer. The only thing it ever asks the internet is whether your subscription is active.
Detection is plain code inside the extension. No AI model of ours reads your messages and no server of ours ever receives them.
The list that matches each placeholder to its real value lives in memory only. It is never written to disk and is erased when you quit Chrome.
When you hover a placeholder, the real value appears in a sealed box the AI site's own code cannot read. It is shown to you, not to them.
Draft recall reminders, referral letters and insurance appeals without pasting patient names or record numbers.
Summarize case notes and draft client letters with names, case numbers and contact details covered.
Ask about a return or reconcile a statement without handing over SSNs or account numbers.
Work on claims, renewals and policy letters while policy and claim numbers stay private.
Write offers, follow-ups and listing emails with buyer and seller contact details hidden.
Polish offer letters, reviews and candidate notes without exposing employees' personal data.

No. Everything happens inside your browser. Your text is never sent to us, and the list of real values behind each placeholder is erased when you close Chrome.
Yes. The AI doesn't need a real phone number to write a good reminder. Placeholders keep the meaning of your message, and the same person always gets the same placeholder, so the AI can still keep track of who is who.
ChatGPT, Claude and Gemini, in Chrome and other Chromium browsers such as Edge, Brave and Arc. More AI sites are on the way.
Names written with no label in front ("write to John about…") aren't detected on their own, so add the names you use often to your private words. Files, images and voice input aren't scanned; Coverword works on the text you type or paste.
No single tool can do that. Coverword lowers the risk of private details reaching AI services by keeping them out of what you send, and it fits well alongside your office's own policies and training.
Subscribe for $5 a month to keep hiding details automatically. If you don't, Coverword still spots private details and warns you before you send, but it won't replace them.
Install Coverword in under a minute and keep using AI the way you already do, with the private parts covered.
Then $5/month. Cancel any time.
