How to Decide
Trilium is a free, open‑source hierarchical note‑taking application popular among researchers and knowledge workers. The alternatives split into a few clear camps: logseq leans into bi‑directional linking and built‑in task management for personal knowledge bases; Joplin emphasizes end‑to‑end encryption and cross‑platform syncing across desktop and mobile; Obsidian is chosen for its local‑markdown file storage with a massive plugin ecosystem and optional paid sync/publish add‑ons; Foam stands out with a graph‑database backend and an extensible plugin architecture with API support; AFFiNE differentiates itself with real‑time collaboration features and a highly customizable workspace with extensive integrations.
When comparing these tools to Trilium, the key factors that actually matter are: 1) the depth of hierarchical organization and linking (how notes are structured and connected); 2) security and privacy features such as end‑to‑end encryption; 3) collaboration capabilities, especially real‑time editing and commenting; 4) platform and mobile support for cross‑device access; and 5) extensibility through plugins or APIs that allow the app to be tailored to specific workflows.
