A second brain built for students
Capture everything once. Ask your knowledge base anything, anytime — with citations back to the original source.
Start freeA second brain is a personal knowledge system that captures the information you encounter and makes it instantly retrievable. Learnd AI is the second brain built specifically for students. Every lecture, PDF, recording, video, and note you add becomes part of a searchable workspace with a cited AI tutor on top.
Why a generic second brain falls short for studying
Tools like Notion, Obsidian, and Roam are powerful, but they are blank canvases. Students need more than a place to put files — they need their material understood, structured, summarized, and turned into active-recall practice. A student second brain has to do the work of learning, not just storing.
How Learnd AI becomes your study second brain
Create a module per course, project, or exam and pour everything in. Learnd AI parses PDFs, transcribes audio and video, indexes web pages and YouTube links, and connects your own notes alongside source material. The AI tutor answers questions across all of it, citing the exact source, page, or timestamp so you can always verify.
Searchable, cited, and ready when you need it
Your second brain only matters if you can find what you stored. Learnd AI lets you ask natural-language questions across every source in a module — "What did the lecturer say about diffusion models?" — and get a direct answer with the original passage. The same workspace generates summaries, flashcards, quizzes, and mind maps from the material whenever you want to study actively.
The retention loop
Capture, organize, understand, remember, retrieve — the five stages every study workflow needs.
Stage 01
Capture
Upload PDFs, slides, lectures, recordings, notes, and YouTube links.
Stage 02
Organize
Learnd AI structures every source into a module you can search across.
Stage 03
Understand
Ask the AI tutor — every answer is cited to a page or timestamp.
Stage 04
Remember
Flashcards, quizzes, and mock exams reinforce material with active recall.
Stage 05
Retrieve
Pull any concept back out of your module weeks or months later.
Loop, not a funnel
every retrieval feeds the next capture.
From scattered materials to structured learning.
01
Add your materials
Upload PDFs, paste YouTube links, record audio, drop in notes — any format you already use.
02
Learnd AI organises everything
In under a minute, Learnd AI reads everything and makes it searchable, citable, and study-ready.
03
Chat, generate, and study
Ask your AI tutor questions, generate flashcards, quizzes, mock exams, mind maps, study plans, and more — all in one place.
Every answer, cited.
Ask anything about your lectures, PDFs, and recordings. Learnd AI shows you the exact page or timestamp behind every answer — so you can always check.
Only from your materials
Exact page or timestamp
Always verifiable
Answers start instantly
Generate the study assets you wish you already had.
Most AI tools stop at chat, flashcards, and quizzes. Learnd AI generates 30+ — built entirely from the notes and lectures you already have.
Card 1 of 24
FRONT
What is photosynthesis?
BACK
The process by which plants convert light energy into chemical energy (glucose) using CO₂ and H₂O, occurring in the chloroplasts.
Built around how memory actually works.
Most AI tools generate content and stop. Learnd AI schedules reviews, mixes up topics, and tests you — the way your brain actually retains things.
Active Recall
Testing yourself is the single most effective way to learn. Learnd AI generates flashcards, quizzes, and practice problems that force retrieval — not just recognition.
Roediger & Butler, 2011
Spaced Repetition
You forget 80% of what you learn within 48 hours — unless you review at the right intervals. Learnd AI's flashcards and quizzes are designed around spaced intervals — so you revisit material right before it fades.
Ebbinghaus, 1885; Cepeda et al., 2006
Mix it up
Mixing up topics during study beats blocking them one at a time. Learnd AI's quizzes and mock exams mix concepts to build flexible knowledge.
Rohrer & Taylor, 2007
Ask yourself why
Asking "why?" and "how?" deepens understanding. The AI Tutor prompts you to explain, connect, and reason — not just memorise.
Pressley et al., 1987
How Learnd AI stays trustworthy
Built to be checked, not just trusted
Answers cite your sources
Every tutor response links back to the exact lecture, PDF, or note it came from, so you can verify before you commit it to memory.
One workspace, many modules
Notes, flashcards, mock exams, mind maps, and summaries all build off the same uploads — no copy-pasting between tools.
Retrieval-grounded, not guesswork
Generation runs over the material you actually uploaded, not the open web. That keeps the output on-syllabus and reduces hallucination risk.
Your uploads stay yours
We don't train AI models on your study material. Files are stored to power your workspace and can be deleted any time.
Frequently asked questions
Notion, Obsidian, and Roam are blank-canvas note tools. Learnd AI is purpose-built for studying — it parses your sources, builds a cited AI tutor on top, and generates flashcards, quizzes, mock exams, summaries, and mind maps from what you upload.
Yes. Modules are private by default. You can choose to share specific modules with classmates or make them public, but nothing is shared unless you explicitly do so.
No. Your uploaded materials are not used to train AI models.
Your next exam doesn't have to be stressful.
