Keep sensitive documents out of AI chats

Ops & admin automation · Dev, web & IT · checked 2026-10-17

Store tax and legal originals in Proton Drive and team credentials in Proton Pass, and give AI tools only redacted copies. A simple habit that prevents most leaks.

#WhoWhat happensHowStatus
1You Keep originals in Proton Drive and shared credentials in Proton Pass team vaults Human step Confirmed
2Proton Pass Shares only the credentials you choose with an AI agent through an access token; the agent must give a reason each time Built-in integration Confirmed · source ↗

4Claude Works only from the redacted copies AI platform Confirmed

Confirmed means the vendor documents it (linked). It doesn't mean IonBin has tested it. AI-platform and human steps need no source.

Human approval

You decide what leaves the vault.

Watch out for

Check each AI provider’s data-retention settings before uploading anything.

Starter prompt

Goal: Use AI for paperwork without exposing personal or company secrets. Tools involved: Proton Pass, Claude. Your part: works only from the redacted copies. Work step by step, show me each draft or proposed change, and wait for my approval before anything is sent, published, signed, filed or changed in a live system.

Which AI platforms can run it

PlatformStatusWhy
Claude (incl. Claude Code) Confirmed No platform-specific connection: the steps run in the tools themselves (browser, upload or built-in).
OpenAI Codex Confirmed No platform-specific connection: the steps run in the tools themselves (browser, upload or built-in).
Google Antigravity Confirmed No platform-specific connection: the steps run in the tools themselves (browser, upload or built-in).
ChatGPT Confirmed No platform-specific connection: the steps run in the tools themselves (browser, upload or built-in).
Gemini Confirmed No platform-specific connection: the steps run in the tools themselves (browser, upload or built-in).
Perplexity Confirmed No platform-specific connection: the steps run in the tools themselves (browser, upload or built-in).

Computed from the MCP and API steps only: "Confirmed" needs the tool's docs to name the platform and the platform to support the connection. Browser, upload and human steps work from any platform.

What we checked (2026-10-17)

  • Proton Workspace. Standard is $12.99 per user per month billed yearly ($155.88 a year), and Premium is $19.99 ($239.88 a year). There’s a 14-day trial. Both include Proton Drive (1 TB or 3 TB per user) and a password manager with team vaults.
  • Pass access tokens. Proton Pass can share selected credentials with an AI agent. The agent has to give a reason each time it uses one, and you can monitor its activity. Proton says this is included on Pass Plus, Family, Professional and Workspace plans.
  • No MCP. We didn’t find a Proton MCP server for Drive.

The habit

  1. Keep originals (tax returns, contracts, IDs) in an encrypted drive, not in chat history.
  2. Before asking AI for help, make a copy and redact names, account numbers, addresses and signatures.
  3. Upload only the redacted copy, and check the provider’s data-retention settings first.
  4. If an agent needs to log in somewhere, give it one scoped credential, not your vault. Teams already on 1Password can apply the same habit there.

This isn’t legal or tax advice. Ask a professional what you must keep and for how long.
