How it works
Three simple steps to smarter learning
AI builds your system
A personalized study plan, concepts, linked notes, smart flashcards and quizzes — generated from your own material.
Learn & track progress
Study with purpose through journeys and spaced review, and watch your understanding grow over time.
Powerful features
Everything you need to learn deeply and retain longer
AI Study Plans
Learning journeys with ordered steps built from your sources, so you always know what to study next.
Source-Grounded Answers
Ask Momentum answers from your uploads with citations, and says plainly when it is speaking generally.
Smart Flashcards
Cards generated from your material and scheduled with spaced repetition based on real recall ratings.
Linked Notes
Markdown notes with [[wiki-links]], backlinks and tags, connected to the exact source section.
Practice & Quizzes
Multiple-choice and short-answer quiz sets with graded attempts that feed straight into mastery.
Progress Tracking
Mastery estimates that show their evidence — and stay honest by saying “not yet measured”.
Use cases
Made for people with real material to master
Students & exam prep
Turn a syllabus, lecture pack or textbook into an ordered journey with review that keeps knowledge fresh.
Professionals upskilling
Work through dense papers and manuals with concept pages, notes and quizzes instead of passive reading.
Self-directed learners
Build a private knowledge graph across everything you read, and share a read-only journey outline when useful.
Private by construction
Your knowledge is private
Files, notes, cards and scores belong to your account only. Nothing you upload appears on this public page.
Secure by design
Row-level security on every table and a private storage bucket — access is scoped to the owning account.
Guided every step
A single workflow from upload to mastery, with clear states for processing, review and what to do next.
Built for real learners
No fabricated scores or invented facts: unmeasured mastery is shown as unmeasured, not as zero.
Pricing

About
One coherent system, not eight disconnected tools
Momentum Learning OS combines an Obsidian-style connected knowledge base with a guided study system. Sources, sections, concepts, notes, flashcards, quizzes, journeys and spaced review live in one workspace, so what you read becomes what you actually know — and every estimate it shows you is backed by evidence it can point to.
