Prompt library: 30+ ready-to-paste instructions for ChatGPT, Claude and Gemini
You type something into ChatGPT, get a bland answer, and conclude *"this bot is dumb"*. The bot is fine, your prompt was weak. This library has 30+ ready prompts (a prompt is the instruction you send to a bot) that someone wrote, tested and polished for you. Click, copy, paste, and see what the bot can actually do when you ask it properly.
Every prompt is split into clear sections: role (*"act as a..."*), goal, rules and answer format. Inside, you'll find blanks to fill in wrapped in curly braces, things like {{topic}} or {{audience}}. Your job: replace them with specifics and paste the whole thing into the bot.
Eight categories: writing, coding, analysis, learning, marketing, business, creative, productivity. Filter by category or search by keyword. Everything is in English and multiple other languages, works the same on ChatGPT, Claude and Gemini.
How to use it
- Pick a category (e.g. *"coding"* or *"marketing"*) or type a keyword into the search box, like *"code review"* or *"LinkedIn post"*.
- Click the card that looks right. A window opens with the full prompt and a short note on what it does.
- Look for blanks in curly braces, things like {{topic}}, {{audience}}, {{length}}. Those are the spots where you fill in your specifics. Replace {{topic}} with *"Next.js 16 for beginners"*. Replace {{audience}} with *"junior frontend dev"*.
- Hit Copy, open ChatGPT (or Claude, or Gemini), paste, swap the blanks for real values, press Enter.
- Below the window you see an estimated token count (a token is a small chunk of text, the bot slices what you paste into pieces and counts each one). Useful when you pay for an API and want a rough idea of cost.
- Some prompts also show a "best bot for this job" hint. Claude is great with long code, ChatGPT shines at brainstorming, and so on.
When this is useful
Six typical situations where the prompt library gives you a concrete edge:
- Junior dev learning to ask the bot well. Sees what a prompt split into sections looks like (role, goal, rules, examples). Clicks *"Code review"*, pastes their code, gets a concrete answer instead of a generic *"looks fine"*. After a few uses, they start writing similar prompts from scratch.
- Marketer hunting for a post idea. Marketing category → *"Social media post"*. The template has separate guidelines for Twitter, LinkedIn, Instagram and TikTok. Paste, swap the topic for your product, and in 5 minutes you have 4 versions ready to publish.
- Product manager writing company goals. Picks the *"OKR"* template (short for Objective + Key Results, basically *"the goal + measurable signs you've reached it"*). Gets a ready structure: ambitious objective, 3-5 measurable results, plus a warning on how not to fall into the *"we hit numbers but missed the point"* trap. Better goals in 5 minutes.
- Recording a project decision. The *"Decision log"* template gives you a clear structure: context, decision, consequences, alternatives, when to revisit. Instead of a loose Slack note, you have a doc you can come back to in a year and still understand why something was chosen.
- Brainstorm that's going nowhere. Instead of *"give me 20 ideas"* (the bot will hand you 20 obvious ones), use the *"Brainstorm 20 ideas"* template. It walks the bot through four modes: safe, optimization, lateral, wild. You get ideas you wouldn't have thought of yourself.
- Learning a new topic. The *"Feynman test"* template (a classic learning method: if you can explain something to a kid, you actually understand it). The bot pretends to be a student and asks *"naive but probing questions"*. In 30 seconds you see exactly where your knowledge has holes.
