Step-by-Step AI Tutorials for Beginners

Introduction

Want to learn AI but don’t know where to start? This guide gives you practical, step-by-step tutorials you can follow today — even if you have zero coding experience. You’ll build real things:

A no-code AI chatbot (live on your website)

AI image generation for blog visuals and social posts

A simple text classifier using Python (train and test in Google Colab)

Each tutorial shows tools, exact steps, example prompts, and what to expect next. Let’s dive in.

Quick prerequisites (what you need)

A modern browser (Chrome/Edge/Firefox)

Free accounts: OpenAI/ChatGPT (or alternative), DALL·E / Stable Diffusion service, Google account for Google Colab

Optional: basic familiarity with copy/paste and downloading files

Time: 30–90 minutes per tutorial (depending on which you choose)

Tutorial 1 — Build a No-Code AI Chatbot (Website Chat Widget)

Goal: Add a simple chatbot to answer FAQs and collect leads.

Tools you can use (no code)

ChatGPT (or other LLM)

Make (Integromat) or Zapier (for integrations)

Tidio, Landbot, or ManyChat (chat widget providers)

Step-by-step

  1. Decide chatbot purpose (30 min)
    Example: “Answer product/service FAQs and collect emails.”
  2. Write 10–20 example Q&A pairs (use your site content)
    Example:
    Q: “What is AbdulwahabDigital?”
    A: “AbdulwahabDigital is a beginner-friendly AI blog helping students and small businesses learn AI.”
  3. Create a ChatGPT (or provider) account

If using ChatGPT, create an API key (optional for widget providers that integrate directly).

  1. Choose a chat widget provider (Tidio or Landbot recommended)

Sign up free, create a chat flow, and pick “Use AI responses” or “Webhook”.

  1. Connect ChatGPT via Zapier/Make

Create a Zap/Scenario: Incoming message → send to ChatGPT API with system prompt + user message → return reply → widget posts reply.

System prompt example (set role/behavior):
You are a helpful assistant for AbdulwahabDigital. Use short friendly answers and include a link to relevant articles when asked.

  1. Test with sample queries, refine replies and add fallback for unknown questions (e.g., “I don’t know — want me to forward this to our team?”).
  2. Publish the widget (copy embed code into WordPress → Appearance → Widgets or directly into your theme’s footer).

Example snippet for system prompt

You are the AbdulwahabDigital assistant. Answer briefly (1–3 sentences), link to relevant blog articles, ask for an email if the user wants a downloadable guide.

Why this works: No coding, fast setup, gives value and collects leads.

Tutorial 2 — Create AI Images for Your Posts (No Code)

Goal: Generate attractive, copyright-free featured images for articles and social posts.

Tools

DALL·E (OpenAI) or Midjourney or Stable Diffusion (DreamStudio)

Canva (for final touchups)

Step-by-step

  1. Pick the image theme for the post (e.g., “futuristic business meeting with robot”).
  2. Use an image prompt template (copy & paste and tweak):

A realistic 3D-style illustration of a humanoid robot interacting with three human professionals in a modern office. High detail, natural lighting, cinematic composition, wide aspect ratio 16:9.

  1. Generate 3–5 versions with the image tool. Compare and pick the best.
  2. Edit (optional) in Canva to add your site logo, headline, or watermark.
  3. Download with web resolution and upload to your post. Add ALT text using the primary keyword.

ALT text example

ALT: Step-by-step AI tutorials for beginners – 3D illustration of a robot and humans in a business meeting

Why this works: Custom images increase click-throughs and give your brand a unique look.

Tutorial 3 — Build a Simple Text Classifier (Python, Google Colab)

Goal: Train a small model in Colab to classify text (e.g., topic detection or spam vs ham).

Why Colab? Free GPU/CPU, no local install required.

What we’ll build

A text classifier using scikit-learn — simple, fast, great for learning.

Step-by-step

  1. Open Google Colab → New Notebook.
  2. Install / Import libraries

Run in Colab cell

!pip install -q scikit-learn pandas
from sklearn.datasets import fetch_20newsgroups
from sklearn.model_selection import train_test_split
from sklearn.feature_extraction.text import TfidfVectorizer
from sklearn.naive_bayes import MultinomialNB
from sklearn.metrics import classification_report, accuracy_score
import pandas as pd

  1. Load a dataset (20 newsgroups built-in)

data = fetch_20newsgroups(subset=’all’, remove=(‘headers’,’footers’,’quotes’))
texts = data.data
labels = data.target

  1. Train/Test split

X_train, X_test, y_train, y_test = train_test_split(texts, labels, test_size=0.2, random_state=42)

  1. Vectorize text (TF-IDF)

vec = TfidfVectorizer(stop_words=’english’, max_features=10000)
X_train_tfidf = vec.fit_transform(X_train)
X_test_tfidf = vec.transform(X_test)

  1. Train a simple model

clf = MultinomialNB()
clf.fit(X_train_tfidf, y_train)

  1. Evaluate

y_pred = clf.predict(X_test_tfidf)
print(“Accuracy:”, accuracy_score(y_test, y_pred))
print(classification_report(y_test, y_pred, target_names=data.target_names))

  1. Try custom inputs

def predict_text(text):
v = vec.transform([text])
pred = clf.predict(v)[0]
return data.target_names[pred]

print(predict_text(“How do I use AI to analyze customer reviews?”))

Notes for beginners

You can replace fetch_20newsgroups with your own CSV (pd.read_csv(“yourfile.csv”)) if you have labeled data.

This pipeline (vectorizer → classifier) is the foundation for many text-based AI projects.

Why this works: Minimal code, instant results, great for demonstrating a real AI application.

Tutorial 4 — Generate Your First AI Prompt Engineering Practice (No Code)

Goal: Improve the quality of AI outputs by learning how to write better prompts.

Step-by-step

  1. Start simple: “Write a 3-sentence summary of [topic].”
  2. Add constraints: “Write a 3-sentence summary aimed at students, include one example.”
  3. Use persona: “You are a friendly tutor. Explain [topic] in plain language.”
  4. Chain prompts (refine outputs):

Prompt 1: “Summarize X.”

Prompt 2: “Make that summary shorter and add one example.”

Prompt 3: “Turn the example into a short exercise.”

Practice improves output reliability — useful for blog writing, lesson creation, and chatbots.

Suggested 30-Day Mini Learning Plan (for hands-on practice)

Days 1–3: No-code Chatbot + image generation for 2 posts

Days 4–7: Complete the Colab text classifier and experiment with different datasets

Days 8–10: Build a content series using prompts (teach others)

Days 11–15: Make short videos (TikTok/YouTube Shorts) showing each project

Days 16–30: Polish projects, write case study posts, reach out to small businesses with sample demo

Tools & Resources (quick list)

Chat & API: ChatGPT/OpenAI, Anthropic, Cohere

Images: DALL·E, Midjourney, Stable Diffusion (DreamStudio)

No-code: Tidio, ManyChat, Landbot, Make, Zapier

Code & notebooks: Google Colab, Kaggle Notebooks

Libraries (Python): scikit-learn, pandas, tensorflow/keras (for image tasks)

Troubleshooting Tips

Bad chatbot answers? Improve the system prompt and add curated Q&A examples.

Low image quality? Increase detail in prompts and try multiple variations.

Model performs poorly? Check data quality, add more labeled examples, try a different algorithm.
