Capacities

What it is for

Capacities is an object-based notes desk: every person, book, or meeting is a type you query, then (on Pro) ask an AI assistant or drop a PDF on the object. Use it when the job is a typed personal knowledge graph, not when you need a meeting notetaker.

What makes it unique: the cover is Capacities’ official docs Book-object still — Books type, Fall of Giants, Author Ken Follett — not a pricing card.

Key features

• Objects + types — unlimited custom types, spaces, and blocks on Free (capacities.io; pricing). A typed graph, not a chat.
• AI assistant — chat, autofill, and media analysis on Pro+ (pricing “AI assistant”). A generate, not an object.
• Calendar — day/week tied to objects (Pro “Calendar integration”). Time, not a note.
• Smart queries — saved filters over types (Pro). A query, not a search box you type once.
• PDF / image / weblink analysis — drop a file on an object and extract (Pro). A parse, not a type.

Readwise / Kindle and the public API sit on Pro. Basic stays free (their published promise). Monthly AI budget vs Plus add-on ($8.33/mo yearly) is the meter. Model names are SKU.

Who it's for

Best fit: researchers and makers who will pay Pro so AI, calendar, and PDF analysis sit on the Free object graph.

Limitations / costs

• $9.99 is the Pro card we copied. Yearly is “−16%”; Plus AI is a separate $8.33 add-on.
• Basic has no AI assistant. Pro is the first AI card.
• Typed PKM, not a PDF whiteboard. For a spatial map, see Heptabase.

Alternatives

• Mem — AI notes without Capacities’ object types.
• Notion AI — team docs when you do not want a typed graph.
