Reflect

Reflect is a networked note-taking application built around backlinks, so every note can connect to related notes and build up a personal knowledge graph over time. It includes an AI assistant powered by large language models for tasks like transcription, outline generation, and grammar correction, plus end-to-end encryption for privacy.

Roam Research

Roam Research is a web‑based note‑taking platform built around bi‑directional links and a graph view, allowing users to create a web of interconnected ideas. Its daily notes page encourages a habit of capturing thoughts as they happen, while the query language lets you retrieve information across the entire knowledge base. Designed for researchers, writers, and knowledge workers, Roam supports markdown, collaborative editing, and real‑time syncing across devices. The platform’s open API enables custom integrations and automation, extending its capabilities beyond personal use.

Notability

Notability is a digital note-taking app that combines handwriting, typed text, live audio recording and transcription, and AI-powered study tools like flashcard and quiz generation. Notes can import PDFs and documents, be searched by handwriting, and be summarized or queried through a chat-with-your-notes feature. Originally an Apple-only app, Notability has expanded beyond iOS, iPadOS, and Mac to Android and the web, with notes syncing across devices. It uses a freemium model with a free Starter tier, several paid subscription tiers, and a one-time-purchase Classic option available to users grandfathered from before the subscription switch.

Capacities

Capacities is a personal knowledge management app built around structured, typed objects (notes, people, projects, books, etc.) rather than a flat pile of documents. Users start from daily notes and create custom object types as needed, and the app automatically surfaces connections between related content instead of requiring manual backlinking for everything.
