25 Productivity Skills for Claude, ChatGPT, and Gemini

In this article, I have compiled 25 skills that you can add to any AI model to skyrocket your productivity.

Each skill is written in .md format, which is the standard for Claude. Even so, you can copy the content and paste it into ChatGPT or Gemini whenever you need to use the skill.

I have organized the skills into 5 categories and also included a video guide showing how to easily add these skills to your Claude agent:

📚 Students

1. Structured Notes Generator

You feed it a topic, a class PDF, or a video transcript, and it returns organized notes with key concepts, definitions, examples, and a visual outline. Like Notion, but automatic.

1. Exam Preparer

Based on notes or a syllabus, it generates multiple-choice questions, essay questions, and practical cases with answers. Basically a personalized mock exam.

1. Learning Roadmap Generator

You tell it "I want to learn X" and it sets up a week-by-week plan with resources, exercises, and checkpoints to measure your progress.

1. Complex Concept Explainer

You pass it a dense concept and it explains it to you with analogies, everyday examples, and levels of depth ranging from basic to advanced.

1. Academic Paper Writer

Structures theses, essays, and papers with academic formatting: introduction, theoretical framework, development, conclusions, and bibliography.

1. Flashcard Creator

Extracts the most important question-answer pairs from notes or texts for review with spaced repetition.

1. Study Session Planner

You tell it how many days you have, how many subjects, and the difficulty level, and it sets up a realistic study calendar with breaks included.

💼 Work Productivity

1. Professional Email Writer

Adapts tone according to context: follow-up, escalation, cold contact, response to complaint... It gets straight to the point and doesn't sound like a robot.

1. Meeting and Minutes Organizer

Converts messy meeting notes into clean minutes with decisions, tasks, responsible parties, and deadlines. So that no one leaves a meeting without knowing what they have to do.

1. CV and LinkedIn Optimizer

You pass it your CV and the job offer you are applying for, and it adapts it by highlighting what is relevant for that specific position. It also optimizes your LinkedIn profile.

1. Presentation Preparer

A topic or briefing → presentation structure with points per slide, narrative, key data, and visual suggestions for each slide.

🔍 Research and Analysis

1. Deep Research Synthesizer

Converts large amounts of information into structured insights and actionable conclusions. Filters out the noise and keeps what matters.

1. Source Validation

Filters information by reliability. Evaluates if a source is credible, detects biases, and tells you what you can trust.

1. Knowledge Structuring

Transforms messy information into clear and usable frameworks. Ideal when you have many loose notes and need to give them structure.

1. Competitive Intelligence

Compares products, tools, or services in a structured way. Strengths, weaknesses, opportunities, and recommendations.

🎬 Video and Visual Content

1. Video Script Generator

Produces structured scripts for short and long-form video with hooks, clear sections, controlled pacing, and CTAs.

1. Hook Generator

Creates openings that grab attention in the first few seconds. For videos, posts, threads, or any content where the first 3 seconds decide if they read you or ignore you.

1. Flowchart Builder

Converts processes into step-by-step flowcharts with nodes, conditional branches, and clear paths.

💻 Code and Automation

1. Code Documenter

You pass it a function, class, or module and it generates clear documentation with description, parameters, return types, usage examples, and edge cases. So you never leave a function undocumented again.

1. Unit Test Generator

Analyzes your code and generates automatic tests covering normal cases, edge cases, and error handling. Compatible with the most used testing frameworks.

1. Debugger Assistant

You paste an error and your code, and it guides you step-by-step until you find the problem and the solution. Like doing pair programming with someone who doesn't get tired.

1. Regex Builder with Explanation

You describe what you want to validate or extract in normal language and it generates the regular expression with a detailed explanation of each part. No more regex copied from Stack Overflow without understanding them.

1. Conventional Commits Generator

Analyzes your code changes and writes descriptive commit messages following the Conventional Commits standard. So your git history stops being a chaos of "fix things" and "update stuff."

1. Code Review Skill

Analyzes code for bugs, inefficiencies, and bad practices. Returns detected problems with concrete suggestions for improvement.

1. Workflow Automation Agent

Breaks down any complex goal into a step-by-step workflow, assigns tools to each step, and optimizes execution.

How to add these skills

Each skill is in .md format. To use them:

1. In Claude: You can add them as part of a Project or paste them directly into the conversation as context.
2. In ChatGPT: Copy the content of the code block and paste it as an instruction at the beginning of your conversation or in the custom instructions.
3. In Gemini: Paste the content as a system prompt or previous context to your query.

The beauty of having skills in .md is that they are modular: you load them only when you need them, and you can combine several in the same session.
