🎮 The Master Framework: "CTRL-PT"

Remember the 6 core AI service categories like keyboard shortcuts

Think of CTRL on your keyboard — you're taking control of AI PowerTools:

1. Comprehend — Natural language processing (sentiment, entities, PII detection)
2. Transcribe — Speech-to-text conversion
3. Rekognition — Computer vision (faces, objects, scenes)
4. Lex — Conversational AI chatbots
5. Polly — Text-to-speech synthesis
6. Textract — Document data extraction

💡 Memory Anchor #1

"I need to CTRL my PT (presentation): Comprehend customer feedback, Transcribe meeting audio, Rekognize faces in photos, build a Lex chatbot for Q&A, use Polly to read slides aloud, Textract data from registration forms."

💡 Memory Anchor #2

"Press CTRL-PT to control your AI PowerTools!"

Why this works: Your muscle memory already knows CTRL from thousands of keyboard shortcuts. We're hijacking that neural pathway.

💬 Language & Speech: "TALK TO COMPUTERS"

The 6 services that enable human-computer communication

This mnemonic follows the natural conversation workflow — from listening to responding:

1. Transcribe — Audio to text
2. Analyze with Comprehend — Text understanding & sentiment
3. Lex — Chatbot conversations
4. Kendra — Intelligent enterprise search
5. Translate — Language conversion (75+ languages)
6. Output with Polly — Text to speech

💡 Memory Anchor #1

"When you TALK TO COMPUTERS: First Transcribe a podcast → Analyze sentiment with Comprehend → Build a Lex bot to answer questions → Kendra searches your documentation → Translate to Spanish → Output audio with Polly."

💡 Memory Anchor #2

"How do humans TALK TO COMPUTERS? Through transcription, analysis, bots, search, translation, and voice output!"

Why this works: The mnemonic creates a story — your brain remembers narratives better than lists. You can literally visualize this pipeline.

👁️ Computer Vision: "SEER"

The 4 vision services that "see" and understand images

A SEER (prophet/oracle) has supernatural vision — just like these AWS services:

1. Scene analysis with Rekognition (objects, activities, unsafe content)
2. Extract text with Textract (OCR for documents, forms, tables)
3. Evaluate faces with Face Liveness (anti-spoofing for authentication)
4. Recognize identities with AnalyzeID (passports, driver's licenses)

💡 Memory Anchor #1

"The SEER can see everything: Scenes in security footage, Extract invoice text, Evaluate if selfies are real people, Recognize driver's licenses."

💡 Memory Anchor #2

"Be a SEER (prophet) of computer vision — see scenes, extract text, evaluate faces, recognize IDs!"

Why this works: The word SEER literally means "one who sees" — it's a semantic match that creates instant recall.

🛡️ Foundation Models: "TITAN HEALTH"

The 6 most powerful generative AI services

TITAN = Mythological giants (Greek mythology)
HEALTH = Keeps your AI applications healthy + medical AI

1. Titan Text — Large language models for content generation
2. Image Generator (Titan) — AI-generated visuals
3. Text Embeddings — Semantic search & RAG applications
4. Amazon Nova — Next-gen multimodal models (Reel, Micro, Lite, Pro, Canvas)
5. Nova capabilities — Video, image, text generation
6. HealthScribe — Clinical documentation automation

💡 Memory Anchor #1

"The TITAN of HEALTH AI: Titan writes marketing copy, Image Generator creates product visuals, Text Embeddings power semantic search, Amazon Nova models handle video/text, HealthScribe documents patient visits."

💡 Memory Anchor #2

"TITAN HEALTH = The giant foundation models that keep your AI applications healthy!"

Why this works: Double meaning — TITAN (powerful/large) + HEALTH (reliability + medical use cases). The mythology connection makes it memorable.

🎪 Individual Service Memory Tricks

🔹 Rekognition = "Rek-a-Face"

Sounds like "wreck a face" but friendly — you're finding/checking faces

Example: "I need to REK-a-FACE in this crowd photo — use Rekognition!"

🔹 Textract = "Text-Tractor"

A tractor pulls crops from the ground; Textract pulls text from documents

Example: "My TEXT-TRACTOR harvests data from PDF fields — Textract extracts everything!"

🔹 Comprehend = "Comprehend PII"

Comprehend means understand; PII is Personal Identifiable Information

Example: "I COMPREHEND the PII (phone numbers, emails) hidden in customer reviews!"

🔹 Transcribe = "Tran-scribe Medical"

A scribe writes things down; Trans- means transform/across

Example: "TRAN-SCRIBE that doctor's recording into medical notes!"

🔹 HealthScribe = "Health-Scribbles"

Doctors scribble messy notes; HealthScribe converts them to structured clinical documentation

Example: "The doctor's HEALTH-SCRIBBLES become structured clinical notes automatically!"

🎯 Certification Exam Tips

When you see an AWS exam question asking about:

1. "Which service transcribes audio?" → Think: TALK TO COMPUTERS → Transcribe
2. "Which service detects faces?" → Think: SEER → Rekognition (or Rek-a-Face)
3. "Which service extracts form data?" → Think: TEXT-TRACTOR → Textract
4. "Which service generates text content?" → Think: TITAN HEALTH → Titan Text
