pricingWith the base Pro or Believer plan you already get every AI workflow, every model in the picker, and a monthly budget sized for trying AI features or very light monthly use. If you want regular AI use, choose Plus.https://capacities.io/pricing
pricingAdd Pro+ (or Believer+ on Believer) for a much larger monthly AI budget — include Plus when you subscribe, or add it later in Settings → Subscription & Billing. You can also wait until your budget resets next billing cycle.https://capacities.io/pricing
pricingEvery Pro and Believer subscriber receives a monthly AI budget that resets each billing cycle. The budget covers all AI-powered features in Capacities: chatting with your notes, analyzing media (images, audio, web links), AI autofill, and AI assistant interactions. All models in the picker are available on Pro and Believer. The included budget is sized for trying AI features or very light monthly use.https://capacities.io/pricing
pricingWith the Plus add-on, your monthly budget is substantially larger: roughly what you pay for Plus, minus transaction fees. That is the plan for regular AI use.https://capacities.io/pricing
pricingYes. If you are on a Plus add-on (Pro+ or Believer+) and exhaust your monthly AI budget before the cycle resets, you can purchase additional AI budget top-ups directly inside the app. Head to Settings → Subscription & Billing to see your current usage and top-up options. See our pricing page for more information.https://capacities.io/pricing
pricingFirst, we want to clarify that AI costs do not drive the subscription fee for Capacities Pro. If you want to use AI regularly, you can expand your monthly budget with Pro+ and Believer+, and purchase top-ups when needed, so as we introduce more AI its cost won’t need to be subsidized by users who don’t want to use it.https://capacities.io/pricing/why
integrationsCapacities is a calm home for what you know. A person or a book gets its own page, linked to everything around it. That shape is what lets your scripts and your AI work with your notes as well as you do.https://capacities.io/developers
integrationsFree to start. The API and AI connectors come with Pro.https://capacities.io/developers

Product HuntCapacities Reviews (2026) / Product HuntGrounded web searchReviewers largely praise Capacities for its object-based approach, saying it hits a useful middle ground between Notion’s structure and Obsidian or Roam’s linking. They repeatedly highlight the clean, fast interface, strong mobile experience, daily notes, flexible tagging, and easy capture for bookmarks, projects, writing, research, and personal knowledge systems. The main caveats are a learning curve, less control or customization than Obsidian for power users, limited offline access, some miss

Limits and method

Limitations and open questions

Known constraints and missing evidence from the collected pages.

The collected pages do not mention specific competitors by name, but they reference Notion, Obsidian, and other note-taking apps in user testimonials S1. Evidence gaps include lack of detailed pricing page content beyond the authoritative table, no explicit uptime or status page information, and no detailed API documentation beyond mention of a public API. Open questions include the exact AI budget limits and the full scope of the API.

Sources, method, and limitations

Evidence inventory, collection method, provider use, and constraints.

This report is based on 15 collected pages from capacities.io, including the homepage, product page, why-capacities page, and pricing page. The catalog includes static and rendered page content, with 177 sitemap URLs mapped. External proof search was performed but no additional verification was completed. Limitations: some pages may have been marketing-focused, and pricing details were supplemented by an authoritative pricing table from the pricing page.
