What I Recommend

For most students, the highest-value combination is:

1. Otter.ai for lecture notes (free tier is sufficient)
2. Perplexity for research (free tier works well)
3. Claude for writing assistance (free tier for light use)
4. Grammarly for proofreading (free tier covers basics)

This combination costs nothing for light use and covers the full student workflow from lectures to research to writing to exam prep. When budgets allow, upgrading to Otter Pro and Claude Pro removes usage limits that heavy users hit quickly.
