Capacities

Capacities is a personal knowledge management app from Capacities Labs GmbH in St. Wendel, Saarland, Germany. Instead of files and folders, it lets you capture notes as typed objects — people, books, projects, meetings, and custom types — and connect them with bi-directional links.

Available on web, desktop, and mobile, Capacities is built for individuals who think for a living: writers, researchers, students, and founders. Daily notes act as a low-friction inbox, while backlinks and related-content suggestions surface connections you already made. Optional AI features can help summarise, translate, and draft from your notes. Data is hosted in certified EU data centres with GDPR compliance, two-factor authentication, and full export in standard formats.

Capacities Labs GmbH is registered in Germany (HRB 108844, Amtsgericht Saarbrücken) and is founder-owned without outside investors. That independence keeps the focus on individual users rather than enterprise bloat.
