| Ignoring the free tier limits | Suddenly losing access mid‑semester | Track your usage (e.g., Otter’s 300 min/month) |
⚡ My 3‑Tool Study System
If I had to start from zero as an online student, I wouldn’t use all 10 tools. I’d use just 3 as a complete system:
| Step | Tool | Job |

| 2. Capture | Otter.ai | Transcribe live lectures, never miss details |
| 3. Memorize | Quizlet | Turn notes into flashcards, quiz yourself daily |
That’s it. Three tools, one workflow.
You can always add more later, but this system alone will save you 5–10 hours a week.
