Why prompts fail
Stop punching trees with your bare hands
Raw AI gives raw results. The difference between noise and output you can ship is the recipe you start from.
You retype the same half-remembered prompt every time, and get different mediocre results.
Install a proven system prompt once. Every session starts with the recipe already loaded.
Generic “act as an expert” prompts produce generic, wall-of-text answers.
Our prompts pin the role, the rules and the output format, so the answer arrives ready to use.
Your notes, tasks and AI chats live in five different places, and nothing connects.
The Second Brain templates give every capture a home, and pair with prompts that fill them.
Prompt lists with 500 entries that you bookmarked once and never opened again.
A curated library, filtered by what you actually do: study, create, code, write, teach.
The Aesthetic Second Brain
A calm home for everything you capture
Minimal workspace templates that pair with the prompt library: capture with AI, organize without chaos.
Crafters' log
What people build with it
Real crafters, real output, pulled from feedback we get every week.
“The flashcard prompt turned my 40-page pharmacology notes into a study deck in one evening. I stopped dreading exam weeks.”
Amara K.
Nursing student
“I used to spend two days per script. The Script Architect prompt gets me a solid structure in twenty minutes. I just add my stories.”
Jonas R.
YouTube creator, 85K subs
“The code review system prompt catches the edge cases I'm too tired to see at 6pm. It's like having a patient senior on call.”
Priya S.
Frontend developer
“The Ruthless Editor cut 28% of my draft and it read better. I was mildly offended and completely converted.”
Miguel T.
Freelance copywriter
“Lesson plans, rubrics and three levels of differentiated worksheets before my coffee gets cold. This library gave me my Sundays back.”

High school teacher

FAQ
Common questions
Still wondering something? Start here.
Is MDCrafter really free?
Yes. Every prompt in the library is free to copy and use, and the workspace templates are free downloads. A Pro bundle with exclusive packs is coming later. The free library stays free.
Which AI models do the prompts work with?
Every prompt is tested with ChatGPT, Claude and Gemini unless tagged otherwise. Image prompts are written for Midjourney. Most prompts are model-agnostic: good structure travels well.
What's the difference between a system prompt and a chat prompt?
A chat prompt is a single well-structured request you paste into a conversation. A system prompt defines the AI's role and rules for a whole session: you install it once in custom instructions, a Claude Project or a Gemini Gem. Each prompt in our library is labeled with its type.
Can I use these prompts for commercial work?
Yes. Use them in your job, your client work, your business. Just don't repackage and sell the library itself.
What is the 'Aesthetic Second Brain'?
Our collection of workspace templates: PARA-style dashboards, planners, trackers and vaults designed to be calm and minimal instead of overwhelming. They pair with the prompt library: capture with AI, organize with the templates.
