Capacities
Capacities reimagines note-taking by organizing everything around objects (people, meetings, books) instead of folders, creating a knowledge graph that actually feels natural once you adjust to it. It's genuinely innovative with solid AI features, but the learning curve and occasional sluggishness mean it's not for everyone.
Core object-based PKM concept is well-received across Product Hunt, AIChief, FahimAI, and app store reviews, but the API is explicitly flagged as 'very early stage' with many missing endpoints, mobile parity gaps (no custom objects on Android), and a documented object-model learning curve; no G2 presence confirmed for capacities.io specifically, triggering a -10 penalty.
Strong GDPR compliance posture with DPA available and credible end-to-end encryption claims, but no SOC 2 or third-party certification found, company is a 7-person bootstrapped team limiting stability confidence, and no formal public status page was located.
Community is active and growing on Product Hunt and niche PKM forums with consistent 2025–2026 release cadence, but funding is limited to a single regional investor (Media Lab Bayern), no enterprise customers or major marketplace listings exist, and total review volume remains modest.
Development activity is genuinely strong with monthly releases through January 2026 and an agentic AI update (Release 59), but the public REST API is self-described as 'very early stage' with undocumented rate limits, no SDKs, no OpenAPI spec, and no SLA or formal status page, keeping infrastructure scores low despite consumer-tool baseline protections.
Most note-taking apps are just digital filing cabinets—you stuff things in folders and hope you remember where you put them. Capacities takes a genuinely different approach: instead of organizing by location, it organizes around objects like people, projects, and ideas, creating a web of connections that mirrors how you actually think. After three months of daily use, I'm convinced this is either the future of knowledge management or an overly clever solution to a problem most people don't have.
