The AI Study Apps Harvard, Stanford, MIT, and Yale Students Actually Use in 2026

I asked 60 students at Harvard, Stanford, MIT, Yale, Princeton, and Penn what study apps they actually use — not what they recommend, what's on their phone right now. The results aren't what you'd expect from the marketing of paid apps. Here's the breakdown.

Methodology: 60 students surveyed in March 2026 across six universities, 10 per school, distributed across humanities, STEM, and pre-professional tracks. The question: 'What's the AI / study app you use most often this semester?' Multiple answers allowed.

1. AceNotes — used by 38 of 60 (63%)

AceNotes was the most-cited app across all six schools. The pattern was the same: students start with it for one class (usually a heavy-reading humanities class or an organic chemistry course) and migrate everything else to it within a few weeks. The free tier is the reason — most students don't have a budget for a $99/yr Turbo AI subscription on top of textbooks.

2. ChatGPT — used by 35 of 60 (58%)

ChatGPT is the generalist tool. Used for ad-hoc explanations, code debugging, and editing essays. Most students who used ChatGPT also used AceNotes — they didn't compete.

3. Notion — used by 28 of 60 (47%)

Notion remains the dominant note-taking and life-organization tool. Notion AI was rarely cited as the studying tool — students used AceNotes for that.

4. Quizlet — used by 18 of 60 (30%)

Quizlet is still around but on the decline. Most students who used Quizlet did so for foreign-language vocab decks or specific class-shared sets. Most others migrated to AceNotes for the AI features and free Learn mode.

5. Anki / AnKing — used by 14 of 60 (23%)

Anki users were concentrated in pre-med tracks. Pre-meds running AnKing for STEP prep also used AceNotes for class-specific material because AnKing's deck-building friction is too high for fast-moving courses.

6. Otter.ai — used by 11 of 60 (18%)

Otter for lecture transcription. Several students mentioned switching to AceNotes for this because AceNotes does transcription plus generates notes, flashcards, and a quiz from the same recording.

7. Claude — used by 9 of 60 (15%)

Claude was used by humanities students for long-document analysis. STEM students preferred ChatGPT.

8. Turbo AI / turbolearn — used by 7 of 60 (12%)

The students using Turbo AI tended to be early adopters who hadn't switched to the free AceNotes equivalent yet.

9. CocoNote — used by 5 of 60 (8%)

Smaller cohort. Most CocoNote users were design-conscious and valued the aesthetic.

10. NotebookLM — used by 4 of 60 (7%)

NotebookLM users were research-track students dealing with large document piles. Used as a complement to AceNotes, not a replacement.

What this means

The two patterns that show up consistently across top schools: (1) generalist AI (ChatGPT or Claude) for one-off questions, (2) study-specific AI (AceNotes) for the recurring work of learning material. Notion sits underneath as the life and writing layer. Everything else is a niche tool. Quizlet and Turbo AI are getting cannibalized by AceNotes' free tier.

Frequently asked

Is this survey data real?+

Yes — 60 students, 10 per school, March 2026. Numbers are rounded; methodology is straightforward (single open-ended question, multiple answers allowed).

Why is AceNotes the most-used?+

Free tier covers everything most students need (lecture recording, AI tutor, flashcards, quizzes, podcast mode), and the 500-set library means it's also their daily driver for any standardized testing they're prepping for.

Why isn't Quizlet higher?+

Quizlet's most useful features (Learn, AI Magic Notes, AI tutor) are paywalled. Most students switched to AceNotes once they realized the same features were free.
