You repeat yourself every session. You accidentally paste API keys into ChatGPT. You wish AI understood your role, your style, your tools. Catalyst Context is the missing layer between you and AI: portable, private, and yours.

The Problem

Your Context Disappears. Your Secrets Don't.

Two problems that existing AI tools completely ignore: your context evaporates every session, and your sensitive data has zero protection.

Context Loss Is the Real Bottleneck

You waste 20% of every AI conversation re-explaining who you are, what you're working on, and how you want responses. Your context doesn't persist, doesn't transfer between tools, and can't be organized or reused.

No DLP Means No Safety Net

There's nothing between you and a data breach. API keys, passwords, client emails, PII. One careless paste into ChatGPT and it's on a server you don't control. No warning. No redaction. No audit trail.

Walled Gardens Trap Your Knowledge

Your custom instructions on ChatGPT don't exist on Claude. Your prompts, your agent configs, your context: all locked to one platform. Switch tools and you start from zero.

How It Works

Three Steps to AI That Actually Knows You

Build Your Layers

Create context layers: agent personas, API keys, knowledge blocks, code snippets. Each with a type, placement, and privacy setting. Your personal AI toolkit.

Search & Select

Open Catalyst Context on any AI chat. Search your layers, check the ones you need, see exactly what will be injected. Full transparency. You're always in control.

Inject & Go

One click injects your selected context as clean XML into the chatbox. Agent personas prepend, knowledge appends. Private keys auto-redact. The AI instantly knows you.

Layer Types

Four Types of Context. Infinite Combinations.

Every layer has a type that controls how it behaves when injected.

Agent

Persona definitions, role instructions, behavioral guidelines. Automatically prepend to set the frame before your message.

<context type="agent">
You are a senior security engineer reviewing code for vulnerabilities...
</context>

Block

General knowledge, project context, reference material. Appends to give the AI background knowledge without changing its behavior.

<context>
Project: Catalyst Context. Stack: TypeScript, Chrome MV3. Target: ChatGPT, Claude...
</context>

Key

API keys, credentials, secrets. Always private by default. Values are redacted to XXXXXX when injected. The AI sees the structure, not the secret.

<context type="key">
AWS Access Key: XXXXXX
</context>

Snippet

Code templates, reusable prompts, document structures. Drop in boilerplate you use constantly without retyping it every time.

<context type="snippet">
async function fetchWithRetry(url, retries = 3) { ... }
</context>
Privacy Protection

Stop Accidentally Sharing Your Secrets With AI

Catalyst Context includes a built-in Data Loss Prevention engine that scans what you type before it reaches the AI. Think of it as spell-check for sensitive data.

Real-Time Scanning

Detects sensitive data as you type, before you hit send. API keys, passwords, credit cards, SSNs, email addresses, and more.

  • 100+ pattern types detected
  • Runs entirely in your browser
  • Zero data sent to any server
  • Inline highlighting with one-click redact

Context-Aware Redaction

Goes beyond pattern matching. Cross-references what you type against your stored private layers.

  • Recognizes your stored API keys inline
  • Warns: "This matches your Production DB Password"
  • Per-site rules (allow on Claude, block on ChatGPT)
  • Custom regex patterns for your org

Audit Trail

Know exactly what was caught, when, and what you chose to do about it. SOC 2-ready compliance reporting with end-to-end encryption.

  • Every interception logged locally
  • Weekly privacy health reports
  • Export for compliance requirements
  • Team admin dashboard (Team plan)

Common Questions

No. On the free tier, everything stays in your browser using Chrome's local storage. Even the DLP scanning runs entirely client-side. On Pro/Team with sync enabled, data is encrypted end-to-end. We never see your content.

Yes. Catalyst Context works on chatgpt.com and claude.ai. Your context layers are the same across both. That's the whole point of portable context.

Custom Instructions are one static block, locked to ChatGPT, with no privacy protection. Catalyst Context gives you unlimited typed layers, works across platforms, includes DLP scanning, and lets you selectively inject different context for different conversations.

When a Key layer is marked "Always Private," the actual value is replaced with XXXXXX when injected. The AI sees the structure (e.g., "AWS Access Key: XXXXXX") but never the real secret. This is on by default for all Key-type layers.

On the Team plan, yes. You get a shared team layer library where admins can create standard contexts (brand voice, code standards, compliance requirements) that everyone on the team can inject. Keys and private layers stay individual.

Free tier includes 20 layers, basic regex DLP (catches API keys, SSNs, credit cards), local storage, and access to free marketplace agents. No time limit. It's free forever.
