10 AI Tools & Real Use Cases

(OpenAI)

Best For

Everyday personal assistance: Memory feature remembers preferences, travel plans, context
Marketing and creative content: Best text rendering in images via DALL-E integration
Deep research reports: Generates detailed reports (36+ pages) with actionable recommendations
Voice conversations: Most natural voice flow and personality
Photo analysis: Analyzes objects, transcribes handwritten notes, diagnoses plants

Not Ideal For

Complex coding projects: Creates "basic clones" lacking features
Matching your writing style: Edits feel "too verbose and sterile"
When you need citations: Use Perplexity for source verification

I use it to find my hidden talents and blind spots. Try: "Tell me something unique you notice about me, but I haven't realized about myself yet."

Taking a pic of my handwritten scribbled notes from meetings and having it transcribe and summarize—game changer.

Claude

(Anthropic)

Best For

Complex coding and full applications: Built "gorgeous Tetris game", playable Mario Level 1
Matching your writing style: "Captures my writing style better than any other model"
Long document analysis: 200K token context window for entire codebases or research papers
Research synthesis: Produces reports that "synthesize insights" with 427+ sources
Artifacts feature: Real-time code visualization with simultaneous execution
Adding type hints and documentation to untyped Python code

Not Ideal For

High-volume usage: Rate limits are #1 complaint
Memory across sessions: Doesn't remember previous conversations
Image generation: Cannot generate images

With ChatGPT I usually have to tweak and critique the code to fit my project. Not so with Claude.

Treat Claude as a senior developer who explains the 'why' behind the code. Ask for reasoning, not just solutions.

Perplexity AI

Best For

Research with citations: Every answer includes clickable source references
Current events and real-time info: Processes 780M+ monthly queries with live web crawling
Academic research: Focus mode narrows searches to academic papers, videos, or Reddit
Price comparisons: Compare product prices across multiple platforms instantly
Advanced search operators: Use 'site:', 'before:', 'after:', and 'filetype:'

Not Ideal For

Creative writing: Built for research, not content generation
Coding: Use Claude or GitHub Copilot instead
Synthesis and analysis: Use ChatGPT for interpreting verified information

Saves hours of traditional Googling. It's like a fact-first, Google-enhanced research buddy with superpowers.

Pro's $20 worth it...saved my team $5K in consultant fees for market research.

Google Gemini

Best For

Massive document processing: 1M+ token context window (up to 2M in preview)
Google Workspace integration: Seamlessly works with Gmail, Docs, Drive
Cost-effective AI development: Gemini Flash is cheaper than Claude Sonnet
Turning documents into interactive experiences: Create games from PDFs
Real-time visual analysis: Live camera mode for debugging while coding

Not Ideal For

Creative writing: Edits feel "too verbose and sterile"
Top-tier coding: Makes "solid games that aren't as visually polished as Claude"
Consistent writing voice: Struggles to maintain tone across long projects

I successfully processed my entire 140-page book when other tools couldn't handle it.

Default to Pro model for complex tasks, only use Flash when you need answers ASAP.

DeepSeek

(V3 & R1)

Best For

Mathematical reasoning (R1): 97.3% on MATH-500 benchmark with transparent step-by-step thinking
Cost-effective AI deployment: 10-30x cheaper than comparable OpenAI models
General-purpose tasks (V3): Content creation, chatbots, knowledge queries
Self-hosting and privacy: Open-source, run locally without cloud dependency
Complex coding logic: R1 tailored for logic-intensive benchmarks like Codeforces (96.3% percentile)

Not Ideal For

China-sensitive topics: Heavy censorship on political content
Data privacy concerns: Chinese company with enterprise compliance concerns
Creative flair: "Provides functional responses but lacks code organization"
Quick answers (R1): R1 is much slower than V3—thinking process can take several minutes

Start with V3 for general tasks and escalate to R1 when a problem demands deeper, more rigorous logical analysis.

Near GPT-4 quality at 5-10% of the cost.

GitHub Copilot

Best For

Real-time code completion: Context-aware suggestions while you type
Boilerplate and repetitive code: Eliminates tedious coding for loops and standard functions
Unit test generation: Generates tests for valid inputs, edge cases, and invalid inputs
Learning patterns and best practices from code suggestions
IDE integration: Native support in VS Code, JetBrains IDEs, Neovim

Not Ideal For

Complex explanations: "Copilot is great for small snippets. I use ChatGPT more for understanding concepts"
Security-critical code: Always review suggestions for insecure patterns
Novel algorithms: Better for common patterns than creative solutions

Use Copilot for small snippets ("add a font-awesome icon to this button"), ChatGPT for bigger logic questions.

It's like having a very knowledgeable coding partner who speeds up development and introduces you to new patterns.

Midjourney

Best For

Artistic and stylized images: "Level of photorealism is mind-bending"
Photorealism: V7 captures fine nuances with great accuracy—appears almost lifelike
Fashion and portraiture: Exceptional for high-fashion shoots with incredible consistency
Creative variations: Generates 4 distinct styles from the same prompt
Moodboards: Upload reference images to create custom style profiles

Not Ideal For

Text in images: DALL-E handles typography better
Precise prompt following: Sometimes interprets prompts creatively rather than literally
Beginners: Requires learning prompting techniques with Discord interface learning curve
Free usage: No free tier. Starts at $10/month

Midjourney is for artistic quality. DALL-E is for ease of use and text accuracy. Most professionals use both.

Cut my concept art creation time in half.

DALL-E 3

Best For

Precision and text accuracy: Handles typography and text in images better than competitors
Ease of use: Seamless integration with ChatGPT for easy refinement
Refining through conversation: Ability to iterate and improve images through dialogue

Not Ideal For

Photorealism: "Still has that AI sheen on skin." Midjourney edges ahead
Batch variations: Midjourney generates 4 variations at once; DALL-E gives one

The ease of refining through ChatGPT is a game-changer.

DALL-E for precision and text, Midjourney for aesthetics. Use both.

Grok

(xAI)

Best For

Real-time X/Twitter Summarizes trending topics and analyzes conversations
Social sentiment analysis: Tuned for decoding public opinion from live social media
Creative/edgy content: "More chaotic and creative. Opinionated, spicy"
Less filtered responses: Designed with "a rebellious streak" to answer avoided questions
DeepSearch mode: Powerful for research tasks with Think mode for complex reasoning

Not Ideal For

Professional/formal work: Humor can interfere with clarity
Serious research: Can hallucinate with "factual accuracy drift" in extended conversations
Work outside X ecosystem: Heavily tied to X platform requiring X Premium subscription

Grok is bolder, more tuned to X's culture. ChatGPT is calmer, more balanced. It's a stylistic difference.

NotebookLM

(Google)

Best For

Document-based research: Upload PDFs, YouTube videos, Google Docs for source-based answers
Audio Overviews: Transforms documents into podcast-style AI discussions
Literature reviews: Upload multiple papers to compare findings and highlight consensus
Study guides and flashcards: Creates learning materials from your own notes and sources
Cross-source analysis: Finds connections across multiple documents humans might miss

Not Ideal For

Real-time web information: Only works with sources you upload
Direct content generation: Designed for analysis, not creating original content
Replacing your note-taking app: Use alongside Notion, Obsidian, etc.—not instead

Got in a 7-minute workout while listening to a custom podcast about the Federal Reserve's Beige Book.

It's like having a writing coach who can analyze your entire story in seconds.
