The workflow that actually works
Don’t try to use all 15 at once. That’s just procrastination with extra steps.
Pick a core 3 based on what you’re working on:
- Research papers: Perplexity → NotebookLM → Grammarly
- STEM courses: Wolfram Alpha → Anki → ChatGPT
- Essay writing: Claude → QuillBot → Zotero
- Group projects: Notion → Canva → Otter.ai
The students getting the most out of AI aren’t using it to skip work. They’re using it to do better work faster finding sources with Perplexity, analyzing them with NotebookLM, writing in their own voice, and cleaning up with Grammarly. That workflow produces stronger papers and doesn’t trigger AI detectors.
AI is a study partner. A fast one, available at 2am, that never gets tired of explaining the same concept three different ways. Use it like that, and you’ll actually learn more.
