Stop Leaking Secrets to AI

You can suspend a model. You can't recall a disclosure.

Your engineers paste credentials, customer data and proprietary source into AI tools every day. Pretense hides it before it ever leaves the laptop.

  • Deploy in 30 seconds

  • No credit card required

  • Work with all AI tools

Works with all AI tools

A Samsung engineer pasted proprietary chip code into ChatGPT three times in one month.

Nobody in that building knew. Not security. Not legal.

This is the part nobody says out loud. Your developers are already using AI every single day, and the security tools you bought were built for a different problem. They watch email and file uploads. They were never built for a senior engineer opening Claude at 2am to fix a release.

The industry spent two decades building walls around the front door. The code walked out through a browser tab.

So we built a firewall for the thing they actually use

Pretense sits between your developer and the AI, like a proxy on the machine. When code goes out, it finds the sensitive parts and swaps them for stand-ins. The AI does its work on the safe version. When the answer comes back, Pretense puts the original values back in place.

The developer writes code the way they always have. The AI answers the way it always has. The passwords, the patient records, the source nobody is allowed to see, none of it ever leaves the laptop.

Hiding the code shouldn't make the AI worse

Other tools redact or block the sensitive parts. That deletes the context the AI needs, and the answers get worse with every prompt. Pretense swaps instead of deletes, so the AI never knows anything is missing.

Redact or block — the old way

The AI gets blanks

The sensitive fields are stripped out before the prompt is sent. The model loses the thread and starts guessing.

# what the AI receives

patient = [REDACTED]

ssn =

record = [REMOVED]

Over a few prompts the accuracy keeps slipping, by 20 to 30 percent in our testing.

Mutation — the Pretense way

The AI gets working code

The values are swapped for realistic stand-ins on your machine. The AI works normally. Pretense reverts them in the response.

# what the AI receives

patient = "alpha_record"

ssn = "BETA-4471-XX"

record = "mrn_beta_009"

Full accuracy, same speed, and the values that matter never leave the machine.

You can have this running before your coffee is cold

No procurement process. No rebuilding your stack. Four steps and you are protected.

01

Install the CLI

One command. Works on macOS and Linux.

$ curl -s pretense.ai/install | sh

02

Create your organization

Name your team so activity and access stay in one place.

03

Generate an API key

This connects Pretense to the AI tools you already use.

04

Start coding

Sensitive data gets swapped automatically before it reaches any model.

That is the whole setup. From install to first protected prompt is about 30 seconds.

Teams that were nervous about AI now ship with it

Setup took less than a minute. We started seeing Code Protection activity immediately across the team.

Sarah Lewis

Backend Developer

We were worried about sending sensitive code to LLMs. Pretense solved that instantly without changing how we work.

Alex Chen

Senior Engineer, Devcore

Pretense gave us visibility and control over how AI tools interact with our code. That's something we didn't have before.

Sarah Kim

Security Lead, Byteshield

Pretence added a layer of trust to our AI workflow. Now our developers can work faster with AI tools while knowing sensitive code stays secure

Jason Lee

CTO, Buildflow

We stopped worrying about sending proprietary code to AI tools. Pretense made that a non-issue.

Rahul Mehta

Security Engineer, Finstack

I haven't seen anything else that protects code before it reaches AI. This is a completely new layer of security.

Daniel Park

Platform Engineer, Infralabs

Pretense sits between your developers and the AI tools they use, like a proxy on the machine. Before any code or prompt reaches an LLM, it finds the sensitive parts and swaps them for realistic stand-ins. The AI works on the safe version, and when the response comes back, Pretense restores the original values. Your real data never leaves the machine.
