Everything you love about Capacities, plus AI, media analysis, smart queries, calendar integration, and the tools to take your knowledge work to the next level.
Free trial available. No credit card required
You've built your knowledge base. Now supercharge it.
You've experienced the clarity of object-based thinking. You've felt the magic of connections surfacing automatically. You've built something valuable.
Pro gives you the tools to do more with it.
Ask your notes questions. Let AI fill in the details. See your calendar and notes in one view. Create dynamic queries that find exactly what you need.
Same simplicity. More power.
"Going Pro was a great decision. This app just keeps getting better and better."
Finally, AI that's actually useful
Not a generic chatbot. An AI that knows your notes, your objects, your context.
Chat with any note
Open a note and have a conversation about it. Ask questions, get summaries, explore ideas—AI responds based on what's actually in that note.
Auto-fill anything
Create a book object → AI fills in author, genre, publication year, summary, key themes. Create a movie → director, cast, runtime, synopsis. Automatic.
Smart commands
Summarize long notes. Translate to any language. Critique your writing. Continue your thoughts. All contextual, all grounded in your notes.
Contextual suggestions
AI suggests tags, collections, and properties based on your content. You approve or ignore. Your knowledge base organizes itself.
"I created a Movies object and I'm able to use AI to auto-populate details like budget and genres and even create links to IMDb. Absolutely insane product."
Unbounded AI work, with Pro+
Pro includes every AI workflow, with a monthly budget for light use and occasional media. Pro+ is the add-on for ongoing AI work: a much larger budget, and top-ups so you can keep going without a ceiling.
Optional on Pro or Believer. Same features. Top up anytime, including auto top-up.
Media
Every file is a thing you can think with.
A photo, a recording, a PDF, a saved article. Each one gets its own page, with properties, links, and your notes beside it. Pro reads them for you, so the words inside show up in search and in AI chat.
The text in your photos, now searchable.
Snap a whiteboard, a receipt, or a page of handwriting. Click Analyze and Capacities reads it.
- Text from any image, even handwriting. Copy it, search it.
- A title, a description, and a category like diagram or receipt, filled in for you.
- The color palette as swatches. Click one to copy its hex value.
Hit record. Get the transcript and the summary.
Meetings, lectures, voice notes. Each recording lands in your space as its own object.
- Record from your desktop or your phone. On Mac, add system audio to capture both sides of a call.
- One click for a transcript and a summary. No prompt to write.
- The spoken words become searchable and ready for AI chat.
Available to Believers in early access. Part of Pro once early access ends.
Mark up the PDF. Keep your notes beside it.
Highlight a passage, pick a color, add a thought. Every highlight links back to the exact spot in the document.
- Highlights and notes on every device. On desktop, snapshot a figure straight into your notes.
- Analyze for a page-by-page reader view, a summary, and keywords.
- Search finds it by the words inside or by what it’s about, and opens the right page. Ask AI chat about it.
Save the article. Read it clean. Keep what mattered.
Paste a link and Capacities saves the page. Open it in reader view, without ads or pop-ups, and highlight as you go.
- Highlights become notes on the link, ready to quote and connect.
- Analyze for a summary, keywords, topic, and category.
- The article stays in your space. Search lands on the matching paragraph.
Reader and analysis run on desktop. Results sync to all your devices.
Analysis runs when you click Analyze. It needs AI turned on and uses your monthly AI budget. Highlights and notes don’t need AI. How media analysis works
Your knowledge, organized automatically
Stop manually organizing. Let queries do the work.
Dynamic views
Create a query once: "All books I rated 4+ stars" or "Tasks due this week" or "Notes from meetings with [Person]." It stays current forever.
Combine any conditions
Date created + tags + properties + collections. "Show me articles tagged 'AI' from the last 3 months that I haven't finished reading."
Embed anywhere
Put query results in any page. Build a "This Week" dashboard, a "Reading List" page, a "Project Status" overview. They update automatically.
Variable queries
Queries that change based on what you're looking at. Open a person? See all your notes with them. Open a project? See all related tasks.
"Queries is the fundamental piece I was waiting for since becoming a Believer. Extremely well implemented, easy to work with."
Your day, in context
Meetings aren't separate from notes. They're connected.
See your schedule
Connect Google, Microsoft, Apple Calendar, or CalDAV. Events appear alongside your daily notes and tasks.
Auto-create meeting objects
Calendar events automatically become objects. Link attendees, agendas, action items, and follow-ups.
Meeting context
Before any meeting, see all related notes, previous meetings with these people, relevant projects, and open tasks.
Timeline integration
Calendar events appear in your daily note timeline. Your day tells a story.
"The calendar integration is a game changer. Brilliantly done—hugely capable, not invasive. Exactly the way I wanted it done."
Tasks that live where your work lives
No more juggling between apps. Tasks embedded in context, surfaced when you need them.
Create from anywhere
Inside a note, from the command palette, on mobile—tasks appear instantly. Link them to projects, people, or any object.
Zero setup required
No configuration, no workflows to build. Built-in views for Inbox, Today, Scheduled, Open, and Completed. Deadlines, recurring tasks, and Kanban boards that organize themselves.
Context that follows you
Open a project? See its tasks. Open a person? See tasks involving them. Tasks appear exactly where they make sense—automatically.
See tasks in your daily flow
Tasks appear right when you need them—in your calendar view alongside your daily notes. Today shows what's due without overwhelming you. Plan your day in one place.
"Started using this today and its one of the most intuitive implementations of tasks with notes around."
Your highlights, ready to think with
Bring your reading into your knowledge base. Readwise, Kindle, or both—highlights become connected notes you can build on.
Readwise & Reader sync
Selectively import documents from Readwise or Reader. Choose what to bring in—no information overload. Highlights stay synced as you add more.
Direct Kindle import
Email your Kindle highlights to Capacities. Chapter structure preserved. Highlight colors intact. No extra subscription needed.
Turn highlights into objects
A quote becomes a Quote object. A person mentioned becomes a Person. An idea becomes a Concept. Your highlights become building blocks.
Process, don't hoard
Refine, annotate, and connect your highlights to other notes. The goal isn't to capture everything—it's to create knowledge you can use.
"I love that the new Kindle integration keeps the colors of my highlights!"
