What Capacities does
Capacities is a personal knowledge studio using typed objects, relationships, daily notes, queries, and AI tools for chat, synthesis, rewriting, translation, and properties.
Capacities replaces a folder-first notebook with typed objects and relationships. Daily notes support capture, while objects, properties, backlinks, collections, queries, media, and calendar or task connections support retrieval and synthesis. AI can chat with selected knowledge, summarize, rewrite, translate, generate text, and fill properties. The approach works best when users define a modest set of meaningful object types, preserve source links and quotations, and separate original evidence from later interpretation or generated prose.
Capacities states that its core product is and will remain free and offers paid Pro and Believer plans. The public rendered pricing page reviewed for this entry did not reliably expose localized amounts, so this listing should not invent a universal price. Users should check the official pricing or checkout for current currency, monthly versus annual billing, taxes, AI query or model limits, storage, feature differences, and renewal. AI-intensive research may incur practical limits even when core note creation remains free.
The January 2026 privacy policy says AI may process selected or search-selected notes, chat prompts, text, media context, and metadata through external AI providers; it states providers do not use the transferred data for model training and store it only temporarily. Users can disable AI, but any personal data deliberately placed in selected context is transmitted. Those commitments do not prevent hallucination. Minimize sensitive context, inspect current providers and transfers, verify generated properties and summaries against sources, retain exports, and obtain qualified review before publishing health, legal, financial, academic, or reputational claims.
How Capacities works
A user captures information as typed objects such as people, books, meetings, or ideas and connects them through links, properties, collections, and queries. AI features receive a prompt plus user-selected or search-selected note context, send the necessary material to an external model provider, and return chat, summaries, rewrites, translations, or proposed properties for the user to verify and save.
How to set up Capacities
Choose a bounded knowledge domain
Define object types, required properties, naming conventions, source links, sensitive content, retention, exports, and cases where AI should remain disabled.
Build a minimal object system
Create a representative set of notes, people, sources, and projects; use links and properties consistently and avoid importing an uncurated archive.
Review privacy and connections
Inspect current AI providers and settings, decide whether external processing is acceptable, connect calendars or tasks narrowly, and exclude confidential material.
Evaluate AI with selected context
Test chat, summaries, translation, rewriting, and property filling on ambiguous and conflicting notes; check every claim and distinguish source text from generation.
Maintain and export regularly
Review inbox notes, duplicates, broken links, stale objects, generated properties, integrations, and usage; keep periodic exports and correct inaccurate synthesis promptly.
Capacities FAQs
Is Capacities free?
Its core product is free. Pro and Believer add paid capabilities; verify current localized amounts, billing cadence, AI limits, and taxes on the official page.
What makes Capacities object-based?
Notes can be typed as reusable objects such as people, books, meetings, or ideas, with properties, links, collections, and queries.
What data does its AI process?
The privacy policy describes prompts and selected or search-selected notes, text, media context, and metadata being sent as necessary to external AI providers.
Can AI features be disabled?
Yes. The privacy policy says users can disable AI features, which prevents related transfer to AI providers.
Does AI understand every linked note correctly?
No. It can omit context, merge concepts, or invent facts and properties. Users must compare output with original notes and authoritative sources.
