When researching unannounced acquisition targets, confidential patent filings, or proprietary drug compounds, PrivacyScrubber tokenizes company and product names into anonymous placeholders before queries leave your device.
The PrivacyScrubber Chrome Extension automatically monitors Perplexity search bars and Pro Search inputs, glowing yellow to warn of confidential data and redacting on shortcut.
Synthesized research answers returned by Perplexity are automatically re-populated with your real entity names locally, keeping full context intact without server logging.
Perplexity Pro Search executes multi-step web searches. Tokenizing inputs locally prevents sensitive corporate queries from being broadcast across third-party web search APIs.
Conduct confidential competitive intelligence and M&A discovery without leaking strategic inquiries:
perplexity.ai inputs for company names and PII.[TARGET_CO] before search dispatch.AI search engines differ fundamentally from standard LLMs, introducing unique search broadcast risks:
When you enter an in-depth query, Perplexity Pro Search breaks the prompt into multiple sub-queries and dispatches them across web search APIs (Google, Bing, Brave), exposing your confidential search intent across external search indexes.
Queries and uploaded files are saved in cloud thread history, where accidental public sharing ('Share Link') can expose proprietary market research to the open internet.
Corporate development executives querying valuations of potential buyout targets inadvertently signal market interest to third-party ad networks and cloud aggregators.
Uploading internal pitch decks, customer survey data, or balance sheets into Perplexity for summarization exposes all underlying direct identifiers to server-side extraction.
Log in to perplexity.ai, click your avatar → Settings → Account, and turn off AI Data Retention to stop model training on your research threads.
With the PrivacyScrubber Chrome Extension active, search inputs on perplexity.ai are continuously scanned for confidential entities. Press Alt + Shift + X (Option + Shift + X on Mac) to tokenize before searching.
Configure custom regex rules for your current deal codenames (e.g. Project Titan → [PROJECT_TITAN]). Perplexity performs deep market synthesis based on the anonymized parameters without recording the true deal name.
When Perplexity delivers citations and summaries referencing [TARGET_CO], click Reveal in the floating extension popover to see full un-redacted intelligence on your screen.
Verify that your search queries cannot be tracked or intercepted:
