If you use AI chat tools regularly, you probably fall into one of two camps.

Either you front-load every conversation with instructions. Before you ask the AI anything, you tell it how to behave: keep it concise, write in plain English, give me the code first, do not open with "Great question!", stop hedging and just answer.

Or you skip the setup, take what the AI gives you, and then spend the next few messages correcting the same things you always correct. "Can you remove the dashes?" "Less formal please." "Shorter." "No emoji." You end up giving the same feedback in chat after chat, day after day, because the AI never remembers how you like to work.

Either way, you are doing repetitive work that the tool should be doing for you. We built Prompt Prefs to fix that.

The idea in one sentence

Prompt Prefs is a simple browser extension that lets you save your AI preferences once, then drop them into any chat with a single tap.

Set it up once. Copy when you need it. Paste. Done.

Why we made it

The quality of an AI's response depends enormously on the instructions you give it. A model told to write concisely, lead with code, and never add disclaimers produces far more useful output than the same model left to guess.

Most people already know this. The problem is not knowledge, it is friction. Writing good instructions takes effort, and re-typing them (or re-correcting the same mistakes) dozens of times a day is the kind of small annoyance that quietly drains your patience without ever feeling big enough to deal with.

So we dealt with it. Instead of carrying your preferences in your head and repeating them, you save them once and reuse them.

How it works

When you open a supported AI chat, a small widget appears in the corner of the screen. Open it and you will see your library: a collection of preference presets you have built, each one tuned for a different kind of task.

Creating a preset takes about a minute. You pick a starting category like Writing, Coding, Research, Business, Creative, or Learning, and each one comes pre-filled with sensible defaults. A short guided flow then walks you through the choices that actually shape an AI's output:

Your choices get turned into clear, direct instructions that AI models actually follow. Not vague labels, but specific commands the model can act on.

When you need it, you tap Copy on the right preset and paste it at the top of your chat. Switching context is just as easy. A preset for code reviews, another for drafting emails, another for studying, each one a single tap away.

A note on privacy

We think this matters, so we will be blunt about it.

Prompt Prefs collects nothing. There is no account to create, no analytics, no tracking, and no network requests of any kind. Everything you create lives in your browser and never leaves your device. There are no servers behind Prompt Prefs because there is no data to put on them.

When you tap Copy, the text goes to your clipboard, and that is the only thing the extension ever writes anywhere. It never reads your clipboard, never touches the content of the pages you visit, and runs entirely offline once installed.

Who it is for

Prompt Prefs works for two kinds of people equally well.

If you are new to getting the most out of AI, it lets you set up good defaults once and forget about them. You do not need to learn prompt engineering. The templates do the heavy lifting.

If you are a power user, it is a context switcher. You probably already have strong opinions about how the AI should behave in different situations. Prompt Prefs lets you save each of those as a preset and flip between them instantly, instead of rebuilding the instructions from memory every time.

Launching soon

Prompt Prefs is a small, simple tool that does one thing well. It is launching soon on the Chrome Web Store, and it is free, private, and lightweight.

Set your preferences once. Use them everywhere.
