A second brain for the semester.

Undergraduates, grad students, and researchers juggling lectures, textbooks, citations, and exam prep across multiple courses. MemX captures the moments and gives them back when exam week comes.

Try MemX Free

94% of university students take notes in lectures; 69% digitally, yet only 5% actually record lectures (Cogent Education / Taylor & Francis, 2024). The reason is simple: nobody wants to scrub a 90-minute recording later. MemX fixes that by transcribing and indexing every voice capture so a question like "what did the professor say about Bayes' theorem?" returns the answer, not the audio file.

Across documents, photos, voice, and chat, MemX gives you a single searchable corpus per semester. Knowledge workers, students included, spend ~9.3 hours per week searching for information (McKinsey Global Institute, 2012). For a student in exam season, those hours are the difference between revision and panic.

How Students Use MemX

Lecture capture without note loss

Record a 90-minute lecture; Voice to Memory transcribes it via Whisper and indexes the concepts. Ask MemX in plain English when you sit down to revise.

Textbook + handout scanning

Document Scanner OCRs PDF chapters and printed handouts. Ask "what did the textbook say about Bayes' theorem?" instead of flipping pages.

Citation & quote recall

Photo Memory captures whiteboard photos and journal-article snippets. Key-fact extraction surfaces exact quotes when you're writing a paper at 2am.

Lab notebook backup

Voice memos during lab work, plus Smart Reminders enforcing protocols like "redo titration at 48 hours." Nothing dies in the back of a paper notebook.

Collaborative study + course-group chats

WhatsApp Import pulls course-group chats into searchable memory: deadlines, professor clarifications, peer-to-peer corrections. No more scrolling 800 messages to find that one date.

University admin paperwork

Enrollment letters, financial aid, transcripts, ID cards. Scan once via Document Scanner; pull any of them up in seconds from a registrar queue or visa office.

Features That Matter to Students

Voice to Memory with Whisper

Up to 60-second captures, server-side transcription via OpenAI Whisper, on-device Silero VAD to auto-stop. ~3× faster than typing on mobile (Ruan et al., Stanford / U. Washington, 2017).

AI Document Scanner with OCR

On-device OCR via Google ML Kit on every PDF chapter, lab report, or handwritten page. Key facts extracted server-side for semantic search.

AI Photo Memory

Background classification detects whiteboard photos, journal-article snippets, document scans. Vacation and selfie photos stay out of the study library.

Ask MemX: RAG across everything

A single chat interface that runs vector search across every memory you have (voice, document, photo, chat) and synthesizes an answer with a citation back to the source.

Smart Reminders from your own captures

Upload a syllabus and MemX suggests deadline reminders parsed from the document itself. Record a lab note and MemX suggests "follow up in 48 hours." You approve or dismiss.

Encrypted at rest with hardware-backed keys

On-device, the local cache uses SQLCipher (AES-256) with its key in Android Keystore / iOS Keychain. Cloud-stored memories are encrypted at rest with the master key in Google Cloud KMS hardware security modules. Your study corpus stays yours even on a shared lab machine.
