AI governance for Gemini
Gemini at work: redaction and visibility
PromptWall redacts sensitive content in every Gemini prompt - gemini.google.com, Google AI Studio, and the Gemini API. NetLens shows how the team uses it.
Real usage
What people paste into Gemini
The patterns we see most often once a team adopts Gemini for real work.
Workspace content pasted for a summary
Google Doc content, Sheet rows and Calendar invite details, pasted into Gemini for summarisation - including embedded customer data and internal financials.
Whole documents in one long-context paste
Gemini's very large context window invites people to paste entire support inboxes, audit reports and design docs in one shot.
Production data tested in AI Studio
Engineers testing prompts in AI Studio often reach for real production data because it's faster than building a fixture.

Gemini, common questions
Does it cover the Gemini integration in Gmail and Docs?
Yes - Workspace AI features call the same Gemini backend. The agent covers the underlying request that the "Help me write" sidebar uses.
Does it work with Google AI Studio?
Yes. AI Studio traffic goes to the standard Gemini API and is covered the same way.
Are my Workspace files at risk if I don't paste them?
PromptWall redacts prompt text a person types or pastes into Gemini - that's the surface it covers. Files that stay inside Workspace without being pasted into a prompt are unaffected either way.
Will this affect Gemini's grounding or search results?
No. Grounding queries are derived from the redacted prompt by Gemini itself, so answers come back based on the redacted but structurally intact prompt.
Does Google Workspace's existing data controls cover Gemini prompts?
Workspace's own controls govern documents and email; they don't inspect what's typed into Gemini. PromptWall fills that specific gap.
