For MBBS students & PG aspirants

The 20th notebook
that builds itself.

Every senior tells you to keep a 20th notebook — one revision notebook bridging all 19 subjects. Almost nobody manages to. BlueTile builds it for you — with your highlights, your comments, your starred topics.

The 20th notebook

Your 20th notebook, the way you'd build it — except it builds itself.

Categorizing 19 subjects by hand is impossible. Maintaining it across 4 years is harder. BlueTile does both — every concept you explore lands in your 20th notebook, organized by subject, automatically.

  • Highlight any line, formula or symptom — there forever, ready when you skim.Coming soon
  • Add your own notes — your mnemonics, your professor's tip, the way you remember it.Coming soon
  • Star important topics for one-tap revision.Coming soon
  • Subject-organized automatically across all 19 NEET PG subjects.
  • Search across everything you've ever studied — instant recall, never lost.

How it builds

Three things happen, every time you study.

01

Explore

Type any topic — a tile generates with a summary, citations, and four related directions to follow.

02

Tile lands

Each tile is synthesized from standard medical textbooks (Harrison's, Robbins, KD Tripathi…) — cited, never fabricated.

03

Filed by subject

Auto-organized in your 20th notebook across all 19 NEET PG subjects. Highlight, comment, star, search — anytime.

What makes it yours

Three habits that make a textbook your textbook.

Three things you can do on every BlueTile concept that flashcards and PDFs can't.

Highlight what matters.

Anything you read, marked the way you'd mark a textbook with a pen. Yours, forever.

YOUR NOTE

Add your own notes.

Your professor's tip, your mnemonic, the way you remember it. Add it to the tile and it lives there.

Why a 20th notebook works

Why a 20th notebook helps — and why your memory isn't to blame.

72%vs 38%

vs 38% — test scores when students studied related concepts mixed together vs. one topic at a time, one day later. A 20th notebook does exactly this — automatically.

Rohrer & Taylor, J. Educational Psychology (2014)

55studies

all agreeing — students using concept-map learning consistently outperformed peers studying traditionally, by a large margin. A 20th notebook is a concept map.

standard medical textbooks — Harrison's, Robbins, Parson's, KD Tripathi and more — synthesized into every page of your 20th notebook. Cited, not fabricated.

How it fits in

BlueTile works with the tools you already love.

Flash cards drill you for active recall. Video lectures walk you through the curriculum. Textbooks give you the source. BlueTile adds the layer that ties everything together — and gives you a 20th notebook to come back to.

The 20th notebook (auto-organized for revision)

Use BlueTile alongside everything else. It's the layer that ties what you've already studied into a 20th notebook you'll actually come back to.

From students

Built with the people who'll use it.

Honestly I just wanted somewhere to dump what I'd already studied so I'd actually find it again. Came back two months later for revision and my MUDPILES note was sitting right under Anion Gap, exactly where I'd left it.

Was reading about beta blockers for pharma and it linked straight to the MI pathophys side. Never get that from notes — I'd have it in two different notebooks and forget the connection. That bit sold me.
Aman K.
PG Aspirant, Delhi
Doesn't replace anything for me — still watch lectures, still do qbanks. But the random doubts I get during a lecture? Those go in here, and it's the only thing I actually re-read before exams.

FAQ

Common questions

Yes. BlueTile's design draws on three of the most-replicated findings in education research: interleaving — students who study related concepts mixed together score 72% vs 38% on next-day tests vs. studying topics in isolation (Rohrer & Taylor, J. Educational Psychology, 2014); concept-map learning — a 2024 meta-analysis of 55 studies in science education found students consistently outperformed peers using traditional methods (Schroeder et al., Educational Psychology Review); and elaborative encoding — connecting new information to a knowledge base produces moderate-to-strong learning gains (Dunlosky et al., 2013). BlueTile is built around the parts of these techniques that usually fail: students don't have to construct concept maps from scratch (the AI does that), and you always get focused depth on a topic before related suggestions appear — so novice learners aren't thrown into the deep end.

Your textbook starts with one topic.

Three of the most-replicated findings in education research — interleaving, concept mapping, and elaborative encoding — woven into one quiet daily habit. Type anything you're curious about. We'll handle the rest.
