Local privacy firewall for AI

Control what leaves your device before it reaches AI.

fAIrewall helps professionals and teams reduce sensitive data exposure before prompts are sent to AI tools.

Built for local-first prompt protection, pre-send minimization, and clearer control across everyday AI workflows.

Works with ChatGPT, Claude, Gemini, and DeepSeek on the web.

AI adoption is moving faster than data control.

AI tools are already part of daily work. The challenge is not just model quality. It is what gets exposed along the way. Personal data, internal identifiers, customer information, and sensitive business context often reach AI tools before governance does.

fAIrewall is built for that reality. It adds a local layer of control before prompts are sent, helping reduce unnecessary exposure without asking users to abandon the tools they already rely on.

A local control layer for real-world AI use

fAIrewall helps you inspect and minimize sensitive content before it leaves the browser.

Detect locally

Identify sensitive patterns in prompts before submission.

Minimize before send

Apply policy-driven protection to reduce unnecessary exposure at the source.

Keep audit visibility

Maintain local visibility for review, accountability, and internal governance.

How it works

Write your prompt

Use your normal workflow in supported AI web apps.

Check and minimize locally

fAIrewall inspects the prompt on-device and applies the selected protection policy before submission.

Send cleaner content

Only the minimized version moves forward, helping reduce unnecessary exposure while keeping the workflow familiar.

Designed to fit everyday AI use without becoming another hosted AI gateway.

Built for practical control, not just theory

Local-first by design

Prompt inspection and minimization happen on the device.

Policy-driven protection

Choose stricter or more flexible behavior based on workflow and risk level.

Broad PII coverage

Built to recognize strong identifiers and privacy-relevant patterns, including EU-focused categories.

Cross-provider coverage

Use one consistent control layer across major AI web apps.

Strict mode available

When required, protection can fail closed instead of silently passing through.

Encrypted local audit trail with signed exports

Keep visibility over sanitization events without routing prompts through a third-party cloud. Export audit records for review and evidence workflows.

Who it is for

fAIrewall is built for privacy-sensitive professionals and teams using AI in real work, including legal, finance, HR, consulting, agencies, healthcare-adjacent workflows, and SaaS teams handling customer or internal data.

It is especially useful where AI adoption is already happening, but internal controls, minimization, and governance are still catching up.
