Double AI Answer Accuracy in 5 Minutes Using One Prompt Formula

Step-by-step guide: structure any request by TCEF (Task - Context - Example - Format) and get dramatically better results

  1. 1.Open Claude (claude.ai) or ChatGPT (chat.openai.com) - both have a free tier without a credit card

    If you already have an account on one of them, use it. If not - pick any and sign up with email

  2. 2.In a new chat, write a prompt using the TCEF formula (Task - Context - Example - Format)

    Copy the structure below and replace [bracketed text] with your specific values. Order can vary, the key is having all four components

    Claude AI / ChatGPT ↗
    Prompt
    Task: [WHAT NEEDS TO BE DONE - specific action, verb]

Context: [WHY AND FOR WHOM - situation, audience, goal, constraints]

Example: [HOW IT SHOULD LOOK - 1-2 samples of the desired result]

Format: [IN WHAT FORM - output the result: list, table, JSON, paragraph, etc.]
    What this prompt doesThis is a template for a universal prompt formula. It works the same in Claude and ChatGPT. Replace [text] with your specific question. For example: Task: Write a headline for an article about AI benefits Context: for a tech blog, target audience - developers aged 18-35 Example: «5 Ways AI Can Speed Up Your Work» or «Why Machine Learning Isn't Science Fiction» Format: maximum 8 words, use bold or numbers at the start
  3. 3.Replace each [placeholder] with your specific request - be precise

    The more specifically you describe the task, context, example and format, the more accurate the answer. Replace vague words (like 'good', 'interesting') with numbers and clarifying terms

  4. 4.Copy the completed prompt into the chat and send it (Enter)

    Make sure spaces between sections are preserved so the AI correctly recognizes the structure

  5. 5.Compare the result with the most basic request - example of accuracy without the formula

    Try asking the same thing in a new chat in one line without the formula (for example: 'Write a headline for an AI article'). You'll immediately feel the difference in quality and relevance

  6. 6.Save your working prompts in a text file or notes - create your personal prompt library

    After each successful request, copy-paste the prompt into a file with a note (for example: 'Works great for headlines, tested on 3 articles'). In a week you'll have a set of ready-made templates
