SafePrompt is a local-first DLP and LLM firewall. Install it and see your first real detection in minutes — every prompt is scanned entirely on your device before it reaches ChatGPT, Claude, or Gemini. No prompt data is ever sent to SafePrompt.
Sign-in required — a free Community account is created automatically, no separate step. Already have one? Sign in.
Blocked: SafePrompt automatically identified your AWS Access Key ID & Secret Access Key. The request was blocked before being sent to OpenAI.
Ready for your whole team? The same Agent prevents employees from sharing sensitive business data with AI tools — everyone protected in 60 seconds, no IT team required, no firewall changes, no training.

The Problem
Employees increasingly use AI to write code, analyze documents, summarize customer information, troubleshoot systems, and automate workflows. But a single prompt can accidentally expose highly sensitive data.
AWS keys, token pairs, and service endpoints pasted into debug windows.
Customer names, phone numbers, email addresses, and contact logs.
Credit card numbers, bank routing keys, and transaction histories.
Patient details, medical diagnoses, and private insurance identifiers.
NDAs, pitch decks, corporate strategies, and board resolutions.
Proprietary algorithms, internal classes, and trade secrets.
Auth credentials, database strings, and system passwords.
Proprietary spreadsheets, CRM dumps, and operational metrics.
Traditional security controls weren't designed for this new interaction layer.
The problem isn't whether your employees use AI. The problem is what they send to it.
Architectural Flow
SafePrompt analyzes content before it reaches the AI service. Sensitive information can be detected and protected at the point of interaction.
Why SafePrompt?
Banning ChatGPT or Claude hurts employee speed. SafePrompt lets your team use their favorite AI models safely by automatically keeping raw credentials, customer PII, and company secrets on the device itself.
Keep your competitive edge. Employees use ChatGPT, Claude, and Gemini securely to draft documents, write code, and solve problems faster.
Sensitive-data detection runs on your device, so raw sensitive values don't need to be sent to SafePrompt's cloud. Get started completely free on your workstation.
No complex proxy setups or cloud round-trips. Prompt interception and protection happen instantly on the endpoint before leaving the browser.
Align easily with SOC2, GDPR, and HIPAA. Maintain a clear logs history of blocked or redacted incidents without storing any raw customer secrets.
No IT team or firewall changes required. Download the agent, sign in with your email, and you are immediately protected.
Manage policies centrally. Set warnings, custom keywords (e.g. project codenames), or block rules across your entire organization.
We document our local ONNX runtime configurations, deterministic vs contextual NER matching models, redact-first verification topologies, and exact capabilities in our technical reference documents.

Customer Stories
We had an engineer accidentally paste our production database URI into ChatGPT while debugging. SafePrompt blocked it and sent a Slack alert in real time. Paid for itself in the first week.
Our legal team was using Claude to summarise NDAs. SafePrompt's file scanning catches the contract content before it leaves our network. Finally a DLP tool that gets AI.
The API gateway feature is a game changer. We rerouted all our internal LLM calls through SafePrompt with one config line. Zero code changes, full DLP coverage.
