AI Tool Rotation
Don't use one AI for everything. Use Perplexity for sources, NotebookLM for learning, Claude for writing, and Wolfram for math. A free rotation beats any $20/mo paid plan.
Using the right tool for the exact right job. They are all free, and they all excel at different things.
You pay $20/month for a Pro plan and try to use it for math, writing, and research—and it fails at two of them.
The Perfect Free Rotation Recipe
Step 1: Prep (Perplexity)
Don't use standard AI to look up facts — it hallucinate. Perplexity actually reads the web and gives you real sources with footnotes.
Search for your topic to gather your initial research papers and get a factual lay of the land.
Step 2: Process (NotebookLM)
Now that you have your facts, you need to digest them. NotebookLM is built specifically for processing your personal documents.
Upload the PDFs, slides, and notes you just found. Generate a study guide, FAQs, or even a fake podcast to listen to while walking to class.
Step 3: Cook (Claude)
It's simply the best AI right now for sounding like a human and catching your logic mistakes without doing the work for you.
Switch to Claude when you actually need to write an essay outline, brainstorm, or code a project.
Step 4: Taste Test (Wolfram Alpha)
Never trust an AI language model to do math. They guess the next word, they don't actually compute.
If you're solving equations or doing physics, use Wolfram Alpha to check your work step-by-step to ensure it's correct.
Step 5: Serve (ChatGPT Voice)
The only time you really need ChatGPT right now is on your phone for spoken practice.
Put in your headphones, turn on Advanced Voice Mode, and have it mock interview you or test you on flashcards while you commute.
