Read the guide →About these guides
Each guide is written for people who already use AI but want to get more from it. We skip the basics and focus on the techniques that actually move the needle - better prompts, smarter model selection, workflows that save real time.
Every guide includes numbered steps, real prompt examples you can copy, and a difficulty rating so you know exactly what you're getting into before you start. All techniques work with the free plan on AskAI.free - no paid subscription required.
Frequently asked questions
Are these guides free to read?
Yes, completely free. All guides are publicly available with no sign-up required. The techniques described also work with the free plan on AskAI.free, so you don't need to pay to follow along.
Which AI model do the guides recommend?
Most guides work well with any major model - Claude, ChatGPT, or Gemini. Where one model has a meaningful edge for a specific task (for example, Claude for long-document summarisation or reasoning-heavy tasks), the guide calls it out explicitly.
How long does each guide take?
Each card shows the estimated reading time before you click. Most guides run between 5 and 15 minutes. The step count is shown too, so you can judge whether to read it all at once or come back to individual steps.
Do I need an account to follow these guides?
No account is needed to read the guides. To actually try the prompts and techniques, you can use AskAI.free without signing up - the first several questions are free without any registration.
Can I request a new guide topic?
Yes. Use the contact page to suggest a topic. We prioritise guides based on reader demand, so if a technique or use case is missing, let us know and we'll consider adding it.
