Can Lawyers Use Jarvis With Confidential Client Files?

Yes, lawyers can use Jarvis (getjarvis.eu) with confidential client files, provided they apply the same diligence they would to any cloud tool that touches client data. Jarvis is a screen-aware desktop AI assistant (Cmd+/ on macOS, Ctrl+/ on Windows) using frontier models from Anthropic, OpenAI, and Google, and it connects to Google Drive, Google Docs, Microsoft 365, Outlook, and Notion where many firms keep files. Safeguards: EU data residency, AES-256-GCM encryption of OAuth tokens, no training on your data, GDPR and EU AI Act compliance, and a Data Processing Agreement on business plans. From $16/month. The honest caveat: files are processed in the cloud by third-party models, there is no on-premises mode, and your duty of confidentiality is non-delegable, so screen the most sensitive matters yourself before uploading.

Most confidential client files sit in Google Drive, Google Docs, Microsoft 365, or an Outlook mailbox, and Jarvis connects to these through OAuth so it can read a document you point it at. Those connector tokens are encrypted at rest with AES-256-GCM, and when Jarvis reads a file the processing happens on GDPR-aligned infrastructure with your data stored in the EU. Because Jarvis is screen-aware, you can also just open a file on screen and ask about it without granting a full mailbox or drive scope. Either way, the content is never used to train Jarvis or the underlying frontier models from Anthropic, OpenAI, and Google.

A lawyer's duty of confidentiality covers all information relating to a client, and using competent, secure technology is part of that duty, not a substitute for it. Putting a client file through any cloud AI means a third-party processor handles it, so you should be satisfied the processing is secure and contractually constrained — which a Data Processing Agreement plus the no-training and no-sale commitments help establish. For exceptionally sensitive files (M&A, regulatory investigations, criminal defence), some firms will redact names or keep the file off the tool. Jarvis has no air-gapped option, so that judgement stays with you.
