Your independent AI firewall. Local, private, and compatible with every AI tool you use.
GhostPrompt detects and replaces sensitive entities in your documents, prompts, and images before they reach any AI tool. One click restores the originals after the AI responds. 100% local. No cloud. No account required.
If you have ever pasted a work document into ChatGPT, you have already taken a risk you probably did not think about. GhostPrompt closes that gap before the next paste.

Why this exists
I built this because I recognized the pattern the moment AI arrived in the workplace.
Over 20 years of shipping products across gaming studios, public-company SaaS platforms, mission-critical 911 and telecom infrastructure, broadcast media, consumer cloud, and federal government technology, I have watched the same dynamic every single time a powerful new tool lands in the workplace. Good people using it faster than their organization's policy can catch up. I saw it with cloud migration. I saw it with BYOD. I saw it with collaboration platforms. When ChatGPT arrived in late 2022 and the generative AI wave came with it, I recognized the shape immediately.
At every organization I have been inside since then, the same thing has happened. People pasting client documents, legal drafts, financial models, meeting transcripts into AI tools because the tools were useful and the work did not stop while the policy committees formed. Nobody being reckless. The tools were genuinely useful, the pressure was real, and there was nothing in place to help people use them safely. So they just went ahead.
The risk was not coming from bad actors. It was coming from good people with no safe path forward. They needed a tool that worked before the data left their machine, without asking permission from IT, without filing a procurement request, without waiting for a policy committee to land. That tool did not exist. So I built it.
GhostPrompt does not ask your organization to change its policies, upgrade its infrastructure, or file a procurement request. It runs locally, on your machine, in the time between when you have a document and when you need to use AI on it. That window is where the risk lives. That is exactly where GhostPrompt works.

Honest about limits
GhostPrompt catches significantly more than manual review. It does not catch everything, and we say that clearly.
Detection accuracy data will be published within 90 days of beta launch from controlled internal benchmark testing across curated document sets. The tool itself collects no usage data from user sessions, ever. Benchmark methodology and test sets will be made available on request. We are a risk-reduction tool, not an absolute guarantee. You remain responsible for reviewing content before sharing with any AI platform.

I want to be straight with you about what this is.
What you are buying
A pre-order. The core engine is in active development. Your license key is emailed the moment you purchase. The download link follows when we ship.
When it ships
Beta within 90 days of your purchase. Stable v1.0 within 180 days. These are binding commitments, not estimates. If either date slips, you hear from me immediately and get a full refund, no friction.
Refund policy
Full refund any time before delivery, same-day, no questions. After delivery: 7 days. EU buyers keep their 14-day statutory right regardless.
What "lifetime" means
Your license covers the full v1.x series, including all updates in that line. Future major versions with team features are sold separately. Your access to the core product never expires.
Important: feature availability: The beta will not ship with all advertised features. GhostPrompt is built iteratively based on real feedback from founding members. Core functionality (detection, replacement, and the restore loop) ships first. Additional entity categories, custom entity libraries, and image support will follow in subsequent releases. You will always know what is available in each release before it ships.
Think of this like backing a Kickstarter. We are actively building GhostPrompt right now. The core detection engine and restore loop are in development, and early backers get locked-in lifetime access at the lowest price we will ever offer. As the product gets closer to shipping, each phase reflects how much development work is already done, not different tiers, just different timing. Every phase gets the identical finished product. Phase 1 buyers back us earliest and save the most. Phase 3 buyers wait until the product is nearly ready and pay closer to launch price. All 500 early access licenses are lifetime. after they are gone, GhostPrompt moves to subscription-only for new users. If you want a one-time price forever, this is the only window to get it.
7-day money-back guarantee. Not satisfied within 7 days of delivery? Email us. Refunded in full, same business day, no questions.
After all 500 early access licenses are claimed,GhostPrompt launches as a subscription product at subscription pricing. Your lifetime license locks in your access forever at today's one-time price , no subscription, no renewals, no price increases. Ever.
The problem
This is happening right now, at organizations you recognize.
The people behind these incidents were not being reckless. They were trying to do their jobs faster, with the best tools available, in organizations that had not caught up yet. That is the real problem. Not bad actors. Good people, moving faster than the policy can.

One paste is all it takes.
No warning. No second chance. Once data leaves your device it is in their system. It may be logged. It may be used for model training. You remain legally responsible for what you shared.
Why it matters
What actually happens when you paste sensitive data into AI.
Most people assume it stays private. The default settings on every major AI platform tell a different story.
Your conversations may be used to train AI models
+
By default, if you use the free or Plus tier of ChatGPT, OpenAI's own policy states that your conversations can be used to improve future versions of the model. Most people never opt out because opting out is not the default. You have to go into settings and find it. The data submitted before you do that has already been sent. Source: OpenAI, "How your data is used to improve model performance," updated 2025.
Human employees at AI companies can read your conversations
+
OpenAI's privacy policy confirms that authorized employees and contractors may access user conversations for safety monitoring, quality assurance, and model improvement. This can be triggered automatically by the system. You receive no notification when it happens, and you have no way to know whether your specific conversation has been reviewed. Source: OpenAI Privacy Policy, February 2026.
Most employees are using personal accounts with no enterprise protections
+
Cyberhaven tracked billions of real-world data movements across 7 million workers and found that 32.3% of ChatGPT usage occurs through personal accounts rather than corporate ones. Personal accounts have none of the data protection guarantees of enterprise plans. The data you submit is governed by consumer terms, not a business data processing agreement. Source: Cyberhaven 2026 AI Adoption and Risk Report, February 2026.
Nearly 40% of all AI interactions involve sensitive data
+
Cyberhaven's 2026 report found that 39.7% of all data going into AI tools is sensitive, including information employees should not be sharing outside the organization. The researchers are clear that this is not malicious intent. It is people using the fastest tool available, not recognizing that what they are doing constitutes a data security incident. Source: Cyberhaven 2026 AI Adoption and Risk Report.
Breaches involving shadow AI cost significantly more
+
IBM's 2025 Cost of a Data Breach Report found that incidents involving unauthorized AI tool use cost organizations an average of $4.63 million. That is $670,000 more than standard breach incidents. Detection takes longer because organizations typically have no visibility into what data entered which AI tool or when. Source: IBM Cost of a Data Breach Report 2025.
Platform breaches have already exposed AI conversations
+
In March 2023, a bug in ChatGPT's infrastructure exposed chat history titles and payment information for a subset of users. In July and August 2025, thousands of shared ChatGPT conversations became publicly searchable on Google due to a misconfigured setting. OpenAI has addressed both issues, but they confirm that data submitted to any cloud platform is only as secure as that platform's infrastructure at the moment you submitted it. Source: wald.ai ChatGPT Data Breaches Timeline, February 2026.
The restore loop
Sanitize before you send. Restore after the AI responds.
GhostPrompt is the only tool that closes the full cycle. You send a sanitized version to AI. When you paste the AI output back, every original entity is restored automatically using a locally-held replacement map. No real data ever left your machine.

Who it's for
Built for people whose work carries real consequences.
If something in your documents could hurt a client, a colleague, or your career if it got out, GhostPrompt was built for you.
Lawyers
The ABA has already said it plainly: uploading client documents to AI may constitute a breach of professional conduct. GhostPrompt lets you use AI for drafting and research without that exposure.
HR professionals
Performance reviews. Compensation bands. Disciplinary records. If that data ends up in an AI system, it is not just a breach. It is personal. GhostPrompt keeps it on your machine.
Consultants and advisors
Your client list, your deal terms, your engagement specifics. That is your entire business. One pasted deck and it is in a model's training data. GhostPrompt sanitizes before you send.
Government workers
Your IT policy is probably six months behind the tools your colleagues are already using in the background. Protected A does not protect itself. GhostPrompt does, locally, without asking anyone for permission.
Product and engineering teams
Your roadmap is your advantage. Paste it into an AI assistant and it stops being yours alone. GhostPrompt sanitizes the sensitive parts before your team hits send.
Researchers and journalists
Your source trusted you with something. That trust does not have an exception clause for AI tools. GhostPrompt makes sure it holds, even when you are using AI to help with the work.

Every objection answered
We have heard all of them.
This is a pre-order. Why should I pay before the product exists?
+
Fair question. Three reasons: you get the lowest price ever available, you directly shape what gets built through the beta process, and we have made explicit legal commitments on delivery timeline. If we miss the 90-day beta or 180-day v1.0 date you get a full refund. The risk is bounded and documented in our Terms.
Why not just trust the AI providers?
+
Even leading AI platforms state that inputs may be used for model training depending on your account settings. You remain legally and professionally responsible for what you share. Hoping they do not log it is not a data governance strategy.
Can I just manually remove sensitive data myself?
+
You can. You will miss things every single time. An email buried in paragraph four. A client name in a footnote. GhostPrompt catches what your brain skips, in under a second, with a manifest you can verify.
How do I know you are not collecting data?
+
You do not need to trust us. Monitor your network traffic while using GhostPrompt and nothing document-related will leave your device. No cloud infrastructure exists. License validation sends only an anonymous device hash, never document content.
What if this never ships?
+
If GhostPrompt is discontinued before delivery, all pre-order purchasers receive a full refund within 30 days. This is stated explicitly in the Terms you agree to at checkout. Your money is not at risk of disappearing without recourse.
Does GhostPrompt work with any AI tool, or only specific ones?
+
It works with every AI tool that exists or will exist, including ChatGPT, Claude, Gemini, Microsoft Copilot, Perplexity, Grok, and any future tools. Because GhostPrompt sanitizes content before you paste or upload it, the AI tool never knows GhostPrompt was involved. There is no integration required, no plugin to install for each tool, and no dependency on any AI provider's API.
What types of sensitive entities does GhostPrompt detect?
+
The first release will cover the most common categories: people's names, organization names, dates, financial figures, email addresses, phone numbers, physical locations, and custom terms you define. Additional entity categories, including legal identifiers, medical terms, and structured data patterns, will be added in subsequent releases based on what founding members actually need. You will always know what ships in each release before it does.
What happens if GhostPrompt misses a sensitive entity?
+
GhostPrompt significantly reduces exposure but does not guarantee 100% detection. If it misses something, that entity goes to the AI as-is. This is why we are honest about being a risk-reduction tool rather than an absolute safeguard. You remain responsible for reviewing content before sharing with any AI platform. The replacement manifest shows you exactly what was detected and replaced, so you can spot any gaps. Anything missed can be added to your permanent custom entity library so it is caught next time.
Can my organization deploy GhostPrompt without IT involvement?
+
Yes. GhostPrompt requires no server configuration, no cloud provisioning, and no network policy changes. Each installation is self-contained on the user's device. Licenses can be distributed and individuals can install independently without IT configuration. For organizations that want centralized deployment, we will support enterprise distribution methods. Individual install works without any IT involvement at all.
How is GhostPrompt different from just manually redacting documents?
+
Manual redaction fails under time pressure, is inconsistent across team members, leaves no audit trail, and cannot restore originals after the AI responds. GhostPrompt detects entities your manual review misses, replaces them consistently, holds a local manifest of every substitution, and restores originals in one click. The restore loop is the part no manual process can replicate. It makes the sanitize, use, restore cycle practical enough to become a daily habit.
Is this useful even if my AI provider claims not to train on my data?
+
Yes, for several reasons. First, provider policies can change. What is true today may not be true after a terms-of-service update. Second, even with no-training guarantees, your data is still transmitted to and processed on their servers, creating exposure to breaches, subpoenas, and policy failures outside your control. Third, many employees use personal AI accounts that carry no enterprise data protections at all. GhostPrompt removes the data before transmission so none of these risks apply.
What is the restore loop and why does it matter?
+
The restore loop is what makes GhostPrompt useful rather than just compliant. After the AI responds to your sanitized input, you paste the AI output back into GhostPrompt. It automatically swaps every stand-in placeholder back to the real entity using the locally held replacement map, so the AI output you work with contains your real client names, dates, and figures, not the fictional ones that were sent. No other tool closes this cycle. Without it, you would have to manually re-insert real information into every AI response, which is slow and error-prone.
How do pricing phases work? Why is Phase 1 cheaper?
+
Each phase reflects the level of development risk you are taking on at the time of your purchase, not just how many people have bought before you. Phase 1 (Founding Member) is open while GhostPrompt is in early development with no beta yet shipped. Phase 2 opens after the beta is live and core functionality is validated. Phase 3 opens as we approach full launch. Phases advance on development milestones. Founding Members are paying less because they are backing something that does not fully exist yet, which is a genuine risk. Phase 3 buyers pay more because the product exists and the risk is lower. Every phase gets the identical finished product.
