Buyer's guide
Code Review for Students: what to know
Students need productivity + study + collaboration software. The free + freemium tier of most major tools covers a student's needs: Google Workspace + Microsoft 365 (free for .edu emails), Notion (free personal), GitHub (free for students via GitHub Student Developer Pack), Figma + Adobe Creative Cloud (free or steep discount for students), Otter.ai for lecture transcription, Anki / Quizlet for spaced repetition, Khan Academy + Coursera + edX for self-paced learning.
The 2024-2026 reality: AI tools (ChatGPT, Claude, Perplexity, Notion AI) have transformed how students study + write. Universities are still figuring out which AI use is acceptable (research + brainstorming usually OK; finished writing usually not). Note-taking is the highest-leverage student tool category: Notion + Obsidian + Roam + Logseq + Apple Notes + RemNote each have strong cases. The right note-taking system + spaced repetition (Anki, RemNote built-in) outperform expensive textbook software.
Challenges Students face
- AI tools usage policy varies by professor + class
- Tool budgets are tight; free tiers + student discounts matter
- Group project coordination across different time zones + tool preferences
- Note-taking system choice (Notion vs Obsidian vs Apple Notes) is a religious war
- Distraction management — same device for learning + entertainment
What to prioritize when picking a tool
- Note-taking + knowledge management (Notion, Obsidian, Apple Notes, RemNote, Logseq)
- AI assistant (Claude, ChatGPT, Perplexity) for research + drafts
- Spaced repetition (Anki, RemNote, Quizlet) for memorization
- Productivity suite (Google Workspace, Microsoft 365) — free with .edu
- Citation manager (Zotero, Mendeley) for research papers
