What is Capacities?

Capacities is a modern note-taking and personal knowledge-management tool built around an object-based model. Instead of organizing everything into folders and flat documents, Capacities treats your notes as connected objects — people, books, ideas, projects, meetings — each with its own structure, that link together into a rich, navigable network. This object-centric approach makes it natural to build a structured "second brain" where information is organized by what it is and connected by how it relates, rather than buried in a folder hierarchy.

Its strengths are structure, connection and a thoughtful, pleasant design. By giving different kinds of content their own object types, Capacities helps you capture and find information in a way that mirrors how you actually think, and the linking between objects surfaces relationships and context as your knowledge base grows. It strikes a balance between flexibility and structure that appeals to people who want more organization than a simple notes app but find heavier tools overwhelming. The clean, focused experience makes building and revisiting your knowledge genuinely enjoyable.

Capacities is a great fit for students, researchers, writers and knowledge workers who want an organized, connected, object-based system for their notes and ideas — a structured second brain that is still approachable. It sits alongside tools like Notion, Obsidian, Tana and Reflect in the personal knowledge-management space, distinguished by its object-based model. If you have struggled to keep your notes organized and connected and want a tool that brings natural structure to your thinking, Capacities is a refreshing, well-designed option worth trying.

What is RemNote?

Taking great notes and actually remembering them are two very different problems, and most apps only solve the first. RemNote tackles both — it's an AI note-taking tool built specifically to help you learn, combining notes, flashcards and PDF annotation in one place.

Notes that become flashcards

RemNote's core trick is turning your notes directly into study material. You write notes (typed or handwritten), and the app can automatically generate flashcards and quizzes from them with AI — so studying isn't a separate chore you procrastinate on, it's a byproduct of taking notes in the first place. That tight loop between capturing knowledge and testing yourself on it is exactly what most study workflows are missing.

Spaced repetition that makes it stick

Those flashcards run on spaced-repetition algorithms, the evidence-backed technique that schedules reviews right before you'd forget something, maximizing long-term retention for minimum effort. RemNote also includes an exam scheduler that personalizes your daily study recommendations based on your test dates — so instead of cramming, you get a steady, optimized study plan that adapts as your exam approaches.

Built for real study sessions

RemNote goes beyond text: you can upload PDFs and annotate them directly, keeping your readings, highlights and notes together instead of scattered across apps. It works offline and syncs across desktop and mobile, so your study materials are with you whether you're at a desk or reviewing on the bus.

One tool instead of five

The real appeal is consolidation. Students often juggle a notes app, a flashcard app, a PDF reader and a planner; RemNote folds all of that into a single connected workflow, which means less time managing tools and more time actually learning.

Who it's for

RemNote is aimed squarely at students preparing for exams — from high school through university and demanding tests like the MCAT and medical school — as well as lifelong learners who want to genuinely retain what they read rather than forget it a week later.

Pricing

RemNote is freemium, with a robust free plan covering the core note-taking and flashcard features, and paid upgrades that unlock advanced AI tools, backups and extra customization. Most students can get real value without paying, then upgrade if they lean on it heavily.

Bottom line: RemNote is the study tool that connects note-taking to memory — auto-generated flashcards, spaced repetition and PDF annotation in one app, so what you learn actually sticks.
