An AI that remembers how you like code explained

Every new AI chat starts from zero, so you re-explain your formatting, your tone, how much detail you want in a code snippet and how you like technical explanations written. Nook is a private AI assistant that remembers those preferences, so you say them once.

Tired of re-explaining your style?

At the start of every chat you type the same instructions again: how you like comments written, whether you want a short answer or a detailed one, one code block or a step-by-step walkthrough, and the tone you want explanations in. It adds up, and it's the same every time.

Tell Nook once

Nook keeps short memory facts that you can see in its Memory panel. When it saves a preference you see "Saved to memory" with an Undo, so nothing is remembered behind your back. A few examples:

• Keep code snippets short, with comments only where something is surprising.
• Explain the why before the how.
• Use TypeScript in examples unless I say otherwise.

Your chats, saved and searchable

Your chats are saved to your account, so they are there on your next visit, and you can search them.

Private to one person

Your Nook workspace belongs to one account: yours. Anyone else who signs in sees that the workspace is private.

Get your own Nook

Nook is opening to more people through a waitlist. Leave your email and we'll let you know when your own private workspace is ready.
