You’ve been hearing for a year that ChatGPT “saves you hours a week”, but every time you open it, you end up with vague answers, copy-paste that needs review, and the feeling that you’ve spent more time than doing it by hand. The problem is almost never the model: it’s the prompt.
In this guide, you have 10 tested prompts — the ones we actually use on the NodoAI editorial team — to chain real daily tasks: reading endless emails, converting meetings into plans, writing messages that are difficult, reviewing your own texts without sounding like AI. Each one with its context, its variant, and how to adapt it to your work.
Why a good prompt matters more than the model
ChatGPT, Claude, and Gemini are context-conditioned reasoning tools. You give it little context → generic response. You give it context, format, and restrictions → usable response. A mediocre prompt with GPT-5 is still mediocre; a well-structured prompt with GPT-4o free saves you 30 real minutes.
The 4 pieces that turn a bad prompt into a good one:
- Role — who the model is in this task (editor, mentor, analyst).
- Task — what you want exactly, not “help me with this”.
- Context — the material or restrictions (length, tone, language).
- Output format — bullet, table, JSON, short paragraphs.
If the answer doesn’t work, it’s almost always missing one of the four.
10 tested prompts that save time
They’re all written to be copied and pasted as is, replacing only the material between {{brackets}}. They work on ChatGPT, Claude, and Gemini without changes.
1. Summary of a long email with editable tone
You paste a long email (complaining customer, 12-response thread, poorly written brief) and return a clear summary plus a proposed response:
Act as my executive assistant. Read this email and return:
1. Summary in 3 sentences (what they're asking, what's urgent, what decisions need to be made).
2. Critical points that I shouldn't overlook.
3. Draft response in a professional but close tone, maximum 100 words.
Email:
"""
{{paste email here}}
"""Useful trick: add at the end "if information is missing to respond, ask me before drafting" and you’ll stop receiving invented responses.
2. From meeting minutes to action plan
Convert chaotic notes into an actionable plan with responsible person, deadline, and next step:
Convert these meeting notes into an action plan in a table with columns:
Task | Responsible | Deadline | Concrete next step
Don't invent responsible people or dates that don't appear. If missing, mark "?".
Notes:
"""
{{paste notes here}}
"""3. Professional responses in seconds
For customer emails that require tact. You give context and desired outcome:
You're the account manager. Draft a response to this customer.
Context:
- We're delayed in a delivery of {{X days}}.
- The real cause was {{cause}}.
- I want: to apologize specifically, give a realistic date, offer 1 compensatory detail.
Tone: professional, without excess, without empty phrases. Maximum 120 words.
Customer message:
"""
{{text}}
"""4. Brief → presentation structure
When you have to set up a presentation from a long brief:
Convert this brief into a presentation structure of {{N}} slides.
For each slide, return:
- Slide title (≤8 words)
- 3 key bullets (≤15 words each)
- A "speaker's note" in one sentence.
Audience: {{who}}
Objective: {{what decision we want}}
Brief:
"""
{{paste brief}}
"""5. Review your own text without sounding like AI
The most underrated prompt. You give your text and ask for surgical review, not rewriting:
You're a tech magazine editor. Review this text and return ONLY:
1. The 5 weakest sentences, with a concrete proposal for improvement.
2. Repetitions of words or structures.
3. Places where the logic jumps or is not understood.
DO NOT rewrite the entire text. DO NOT add conclusions. DO NOT use words like "fundamentally", "innovative", "robust", or "it's important to highlight".
Text:
"""
{{your text}}
"""6. Quick comparison to make a decision
When you’re in doubt between 2-3 options (tool, plan, provider):
Compare these {{N}} options for my case. Return a table with:
- Real cost (not "check")
- Learning curve
- Main risk of choosing that option
- Who it's ideal for
My case: {{describe case}}
My priority: {{what matters most}}
Options:
1. {{option A}}
2. {{option B}}
3. {{option C}}
At the end: give me your recommendation in one sentence with the reason.7. Structuring a project from scratch
Useful for freelancers or when leading something new:
I'm going to start {{project}}. I want you to break it down into phases.
For each phase, return:
- Name
- Measurable objective
- 3-5 concrete tasks
- Main risk
- How long it usually takes someone with average experience.
Don't include motivational filler. Don't assume I have a team.8. Extracting key information from a long PDF
Works best in Claude and ChatGPT Plus, which accept attachments. If you’re using the free plan, paste the text:
Read this document and extract:
1. The main thesis in 1 sentence.
2. The 5 most relevant numerical data (with page or section).
3. Any statement that needs verification.
4. What's NOT covered and what an expert reader would miss.
Document:
"""
{{paste text or upload file}}
"""9. List of tasks you can really do
To empty your head at the end of the day without falling into “infinite list”:
I have this set of pending tasks. Organize them into 3 groups:
1. To do today (maximum 5, the ones that really move the needle)
2. To schedule for this week (with clear criteria for when)
3. To eliminate or delegate (be honest, mark the ones that don't contribute)
Pending tasks:
"""
{{paste them as is, raw}}
"""10. Writing uncomfortable messages
The one most people use in private: asking for a raise, canceling a subscription, saying no to a project:
Write a message for {{situation: asking for a raise / canceling / saying no / apologizing}}.
Data:
- To whom: {{person, relationship}}
- What I want to achieve: {{clear outcome}}
- What I DON'T want to seem: {{aggressive / weak / imprecise}}
- Tone: direct, respectful, without clichés.
Return 2 versions: one more formal and one more casual. Maximum 120 words each.How to adapt these prompts to your work
These prompts are not magic recipes: they’re templates you can save in your note app (Notion, Apple Notes, Obsidian) and duplicate when you use them. Three adjustments that multiply their usefulness:
- Add your role at the beginning. If you’re a marketer, “act as my content editor”. If you’re sales, “act as my sales coach”. The model reasons within that frame.
- Define the “no” before the “yes”. Saying “don’t use words like X, Y, Z” works better than asking for an abstract style.
- Iterate instead of rewriting. When the response doesn’t fit, don’t start from scratch: ask “rewrite bullet 3 shorter” or “the tone was too formal, lower it a bit”.
3 errors that kill productivity with prompts
- Prompt-throw-and-accept. If you copy the first response without reviewing, at some point you’ll publish a hallucination. Always read before pasting.
- Asking the model to invent data. ChatGPT will keep going even if it doesn’t know. If you ask for a number or date and don’t have it in context, give it a source or ask it to say “I don’t know”.
- Using it for tasks that don’t need AI. A 3-word response to your colleague doesn’t deserve a prompt. Real productivity is in when to open ChatGPT, not in always opening it.
Frequently Asked Questions
The most typical doubts we see on the team:
What’s the best model to use these prompts in 2026?
For professional text, Claude Sonnet 4 (paid) or GPT-4o (free with limits). For tasks with many numerical data or long PDFs, Claude handles extended context better. For integration with Google Drive and Gmail, Gemini Advanced.
Do these prompts work in Spanish or is it better to translate them to English?
They work perfectly in Spanish. The quality difference between Spanish and English in top models in 2026 is marginal. Only translate to English if the original material (PDF, brief, code) is already in English.
How much time is really saved?
Depends on the task. Email summaries and text review: 15-30 minutes a day if you use them frequently. Response templates: 1-2 hours a week. In-depth research: more variable, because it requires verifying sources.
Is a paid plan necessary for these prompts to work well?
No. The prompt structure matters more than the plan. What changes with the paid plan: longer context, attached files, priority in peak hours, and premium models (GPT-5 or Claude Opus). If you only need short-medium professional text, the free plan is enough.
How do I avoid my texts sounding like AI?
Three rules: 1) use prompt 5 (review your text) instead of asking it to write for you; 2) block typical model signal words (“fundamentally”, “it’s important to highlight”, “innovative”); 3) rewrite the introduction and conclusion yourself. The model is a good editor, bad author.
What’s next
If these prompts fit you, the next natural step is to set up a workflow: combining them with automations so they trigger automatically when an email arrives or a meeting closes.
