Your Context

Ready to share

👤

Identity

Senior Developer 5 years exp

Tech Stack

Concise code Functional style

The Problem

AI companies move fast.
Your context gets left behind.

New model, new rules. New chat, blank slate. Your expertise is locked inside platforms you don't control.

🔄

Identity reset

Every AI session erases who you are. Your role, stack, and project context — gone. Every. Single. Time.

🧠

Memory is a lie

Claude "remembered" your preferences. Until the next update wiped them. AI memory is rented, not owned.

🔀

Platform lock-in

Comfortable with ChatGPT? Great — until the next price hike, policy change, or feature removal. Your context is hostage.

The Solution

Your context.
Your rules.

Take control of what you share. Switch seamlessly when platforms pivot.

✏️

Build your profile

Your expertise, projects, and response preferences. Two minutes to set up. Yours forever.

🔐

Authenticate & control

Face ID ensures only you share. Choose exactly which context goes to which AI. Granular control.

✨

One tap, any AI

Copy your context. Paste into ChatGPT, Claude, Gemini — any AI, any platform. They instantly understand you.

See the difference

Same question.
Dramatically different answers.

Without ContextKey

"How should I structure this API?"

"There are many ways to structure an API. You could use REST, GraphQL, or gRPC. It depends on your use case. Could you tell me more about your project, tech stack, and team experience?"

Generic. Starts at zero.

With ContextKey

"How should I structure this API?"

"Given your TypeScript/Node.js stack and preference for functional patterns, I'd recommend a REST API with Express and Zod validation. For your e-commerce project, here's a clean module structure..."

Personalized. Instant context.

Why ContextKey

Not just another
custom instruction.

ChatGPT has Custom Instructions. But that's not the same thing.

FAQ

Questions answered.

Is my data secure?

All data is stored locally on your device with AES-256 encryption. API keys live in the iOS Keychain. Nothing is sent to any server. Ever.

Is it free?

ContextKey is free to use. No subscriptions, no hidden fees, no ads. The beta is available now via TestFlight.

Does it store my AI conversations?

No. ContextKey stores your profile context — not your chat history. The AI extraction feature processes text on-device and discards it after.

How is this different from Custom Instructions?

Custom Instructions are locked to one platform. ContextKey works across every AI — ChatGPT, Claude, Gemini, and more. Your context, portable.

Does it integrate or just copy/paste?

Currently it copies formatted context to your clipboard, optimized for each AI. Direct API integrations are on the roadmap.

What happens to my email when I sign up?

Your email is only used to send beta access. We don't share it, sell it, or spam you. See our privacy policy.

Stop renting your identity
to AI platforms.

Own your context. Share on your terms. Switch without starting over.
